Antihypertensive Agents

Combination Drugs Used for Hypertension Minoxidil, oral General Statement The Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure classifies BP for adults aged 18 and over as follows Optimal as < 120 < 80 mm Hg, Normal as < 130 < 85 mm Hg, High Normal as 130-139 85-89 mm Hg, Stage 1 Hypertension as 140-159 90-99 mm Hg, Stage 2 Hypertension as 160-179 100-109 mm Hg, and Stage 3 Hypertension as 180 or greater 110 or greater mm Hg. Drug therapy is recommended depending on the BP and whether certain risk factors (e.g., smoking, dyslipidemia, diabetes, age, gender, target organ damage, clinical CV disease) are present. Life-style modification is an important component of treating hypertension, including weight reduction, reduction of sodium intake, regular exercise, cessation of smoking, and moderate alcohol intake. The goal of antihypertensive therapy is a BP of < 140 90 mm Hg, except in hypertensive diabetics...

Initial assessment of severe hypertension

When severe hypertension is noted, the measurement should be repeated in both arms to detect any significant differences. Peripheral pulses should be assessed for absence or delay, which suggests dissecting aortic dissection. Evidence of pulmonary edema should be sought. C. Prescription drug use should be assessed, including missed doses of antihypertensives. History of recent cocaine or amphetamine use should be sought.

High Blood Pressure and Kidney Failure

Hypertension (high blood pressure) is a common feature of renal failure. It appears in most patients at some point as the disease progresses. The reasons for hypertension in almost all patients with chronic kidney disease (in addition to those whose hypertension is their primary disorder) are complex, but have to do with hormones produced by normal kidneys that regulate blood pressure, especially hormones that control sodium balance. In susceptible people, retention of sodium increases blood pressure, and hormones that increase the sodium content of the body tend to be produced in increased amounts. Other hormones may play a role in hypertension as well, including parathyroid hormone and insulin, both of which tend to rise in patients with hypertension. The body tends to pro duce decreased amounts of substances normally released by the kidneys that lower blood pressure. For these many reasons, high blood pressure is a very common feature of kidney failure. Occasionally people have...

Treating High Blood Pressure

Based on your frame size, you may learn that you exceed your ideal weight. If so, don't be alarmed. Most Americans exceed that weight. There's no need to achieve model thinness, because losing just a few pounds can have substantial medical benefits. Losing as few as 10 pounds can drop your blood pressure by about 7 points. This alone can mean the difference between hypertension and high-normal blood pressure. Loss of a pound or two a week is about right. Crash diets that promise you'll lose weight faster usually have only temporary benefits the weight comes back. Diets rich in fruits and vegetables can be extraordinarily effective in lowering blood pressure, partly because they are rich in potassium, which counteracts sodium's effect on blood pressure. Even if you don't have hypertension, losing a few pounds may help keep your blood pressure in the normal range. Sodium, one of the ingredients of sodium chloride (table salt), plays a major role in hypertension. As mentioned, Americans...

Medications for High Blood Pressure

Before getting into specifics about drug treatment of high blood pressure in people with kidney disease, I want to emphasize some general principles. The lowest effective dose should always be used. It is necessary to start on a dose that will not be fully effective and to increase the dose gradually until you reach the lowest effective dose. Antihypertensive drugs all cause dose-dependent adverse effects, and unfortunately they often are prescribed in doses higher than necessary. The goal is to reduce blood pressure throughout the 24-hour period. Taking your drugs at bedtime is not a good idea you need to control Treatment works only if you take the prescribed medications. Research has found that only half of people with high blood pressure continue their medications after a few months. Just why this is so is uncertain. Part of the reason is because of side effects, which are numerous, but some people seem to quit for no apparent reason. Blood pressure varies a good deal from day to...

Intracranial Hypertension

The normal intracranial pressure (ICP) is 60-120 mmH2O, which corresponds to 5-15 mmHg. An ICP greater than 30 mmHg impairs cerebral blood flow an ICP greater than 50 mmHg for more than 30 minutes is fatal an ICP greater than 80 mmHg for any length of time can cause brain damage. Intracranial hypertension may be either acute (developing in hours to days) or chronic (lasting for weeks or months). Its manifestations are progressively more severe as the ICP rises, but are not specific thus, the diagnosis cannot be made from the signs of intracranial hypertension alone but requires either the demonstration of a causative lesion (e.g., subdural hematoma, encephalitis, brain tumor, hydrocephalus) or direct measurement ofthe intracranial pressure. Treatment is indicated when the ICP persistently exceeds 20 mmHg, when plateau waves are found, or when the pulse amplitude rises. Individual cases may manifest a variety of different signs of intracranial hypertension, either in slow or rapid...

Modified Dandy Criteria for Idiopathic Intracranial Hypertension

Note the typical patient profile (typical patient see Table 13) of a young obese woman is not required by these criteria, although the presence of idiopathic intracranial hypertension in a child, man, or thin or elderly individual would now be classified as being an atypical case. (Adapted with permission from Friedman DI, Jacobson DM. Diagnostic criteria for idiopathic intracranial hypertension. Neurology 2002 59 1492-1495, and from Lippincott, Williams, and Wilkens.)

Hypertension Introduction

Hypertension in children is reflected by the consistent readings of the systolic and or diastolic blood pressure at the level of or above the 95th percentile for age and sex. It may be primary or secondary. Fifty to 80 of secondary hypertension is caused by renal parenchymal disease therefore, infants and children with hypertension and adolescents with severe hypertension need to be evaluated for renal pathology. Hypertension in children is of particular concern because of its close association with adult hypertension. Children with increased blood pressure usually do not display any overt symptoms. Blood pressure determinations are a part of routine examination in children 3 years and older. Children under 3 who have been diagnosed with a heart condition are also screened for hypertension.

Definition Classification and Diagnosis of Hypertension

Hypertension is a disorder of the cardiovascular system characterized by elevated arterial blood pressure. The blood pressure in the arteries is dependent on the energy of cardiac contractions, elasticity, and contractile state of arterial walls, as well as on the volume and viscosity of the blood. It fluctuates with every heartbeat. The maximal pressure occurs near the end of the stroke output and is termed systolic. The minimal pressure occurs late in ventricular diastole and is termed diastolic. Individuals with a systolic blood pressure at or under 120mmHg and diastolic pressure at or under 80 mmHg are considered normotensive. The term 'prehypertensive' is used for individuals with a systolic pressure under 140, but above 120 mmHg and diastolic pressure under 90, but above 80 mmHg. Patients with 140-159 mmHg systolic and over 90 mmHg diastolic have phase I hypertension, while patients with systolic pressure over 160 mmHg and diastolic pressure over 100 mmHg have phase II...

Treatment of hypertension in preeclampsia

Severe hypertension should be treated. In adult women, diastolic blood pressures > 105 to 110 mm Hg or systolic pressures > 160 to 180 mm Hg are considered severe hypertension. In adolescents, treatment is initiated at diastolic pressures of > 100 mm Hg. 3. Occasionally, preeclamptic women with severe hypertension are stabilized and not delivered. In these patients, oral antihypertensive therapy is often indicated. The only oral drugs that have been proven to be safe in pregnant women are methyldopa (250 mg twice daily orally, maximum dose 4 g day), and beta-blockers, such as labetalol (100 mg twice daily orally, maximum dose 2400 mg day).

Surgically Induced Hypertension

One of the major discoveries in hypertension research in the twentieth century was that of Goldblatt and his associates in 1937. They occluded the main renal artery of one kidney in six dogs and found that renin levels in the peripheral blood of these animals substantially increased. Over the next 3-4 days the mean systemic blood pressure in these animals also increased by an average of 104-139 mmHg. The Goldblatt technique was later used in rats and more recently in mice and led to the establishment of models with transient or permanent renal artery occlusion with or without unilateral nephrectomy. These models are referred to as two kidneys one clip (2K1C) or one kidney one clip (1K1C) hypertension models. The initial phase of hypertension in either of these models is associated with a rapid increase in plasma renin levels and a subsequent increase in Ang II formation. In the 2K1C model, the RAS remains activated for at least 9 weeks after occlusion of the renal artery. After a few...

Mineralocoticoid Hypertension

In 1942 Selye described experimental mineralocorticoid hypertension in rats produced by desoxycorticosterone acetate (DOCA) and salt. It is a low-renin salt-dependent model, which has been widely used in the evaluation of antihypertensive drugs. Recently this model has been shown to be useful in the evaluation of endothelin antagonists. The endothelin system was found to be involved in the pathogenesis of low-renin hypertension16 and endothelin antagonists lower arterial pressure in DOCA-salt hypertensive rats. Iglarz et al17 reported that rosiglitazone, an activator of peroxisome proliferator-activated receptor g (PPARg), prevents the development of hypertension in DOCA-salt rats.

Spontaneous Hypertension

The first strain of rats with inheritable hypertension was bred in New Zealand by Smirk and Hall and is known as New Zealand hypertensive rats. Most of the currently available SHRs are derived from the strain developed in Japan by Okamoto and Aoki. The substrains of Okamoto-Aoki rats have undergone changes and differ in various aspects from the original strain. Okamoto-Aoki SHRs have been cross-bred with strains with other inheritable abnormalities, including hyperlipemia and obesity. The stroke-prone SHRs (SPSHRs) die from a type of stroke that resembles a rare The importance of salt intake in the pathogenesis of hypertension has been explored using Dahl salt-sensitive (DSS) and Dahl salt-resistant (DSR) rats. It has been reported that optimal dietary potassium chloride (2.6 ) can prevent hypertension and protect cerebral and renal vasculature in DSS rats fed a 1 sodium chloride-containing diet for 8 months.19 Lighthall eta .20 detected three new salt-sensitive genes in the kidneys...

Treatment of Hypertension

The current JNC VII guidelines recommend that antihypertensive therapy should start with a thiazide diuretic or a b-adrenoceptor antagonist as the first choice and newer drugs should only be added in special circumstances.1 Some investigators disagree, however, with the JNC recommendations and feel that drugs inhibiting RAS - ACE inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) - should be the first-line drugs in the treatment of hypertension, since they provide benefits beyond blood pressure reduction. Extended-release formulations of calcium antagonists are also often used as first-line therapy.

Drug Resistant Hypertension

Many cases of drug-resistant hypertension are in reality unrecognized failures of compliance. There are, however, patients who do not respond to any of the available drugs or their combinations. The most common cause of drug-resistant hypertension is atheroscleroric renal artery disease. These patients may respond to minoxidil, a highly effective vasodilator. Its side effects include tachycardia and hair growth, as well as sodium and water retention. Because of its side effects, it is rarely used clinically. The mechanism of its antihypertensive action involves activation of vascular KATP channels. There is a need for a safer Katp channel activator for the treatment of drug-resistant hypertension.

Pulmonary Arterial Hypertension

Pulmonary arterial hypertension is a debilitating and fatal lung disease. Patients are diagnosed as having pulmonary arterial hypertension if their mean pulmonary arterial pressure exceeds 25 mmHg at rest or 30 mmHg during exercise. Pulmonary arterial hypertension is subdivided into primary and secondary. Primary pulmonary hypertension (PPH) is idiopathic, while secondary pulmonary hypertension is caused by other diseases, e.g., pulmonary fibrosis, thromboembolism, or drugs. Some 6-12 of PPH patients have familial PPH, which is an autosomal dominant disease. In many families with PPH, mutations of the bone morphogenetic protein receptor type II (BMPR2) gene have been identified. Idiopathic pulmonary arterial hypertension has a particularly poor prognosis. Without lung transplantation the average survival time is 3 years after diagnosis.45'46 In the past the therapy of pulmonary arterial hypertension has been disappointing, although CCAs have been tried with some success....

Systolic Hypertension

Isolated systolic hypertension is common in patients over 65 years of age. Its prevalence in the elderly has been estimated to range from 34 to 65 . It is associated with the structural changes of arterial wall that include thickening of the intima, fibrosis of the media, and degeneration of the elastic fibers. These changes lead to stiffening of the arteries. Prevention of vascular changes should be an important goal in the therapy of isolated systolic hypertension. Since Ang II is one of the profibrotic factors, ARBs are likely to protect arteries from fibrotic degeneration. ARBs, ACEIs, CCAs as well as combinations of ACEIs and CCAs have been used in the therapy of isolated systolic hypertension. However, all these drugs reduce diastolic blood pressure as well. A large clinical trial designed to determine which drugs are more likely to reduce cardiovascular mortality and morbidity safely in patients with isolated systolic hypertension will be completed in 2008.49

Pathophysiology Biochemistry and Genetics of Hypertension

The pathophysiology of essential hypertension has been extensively studied over the last 50 years. Peripheral vascular resistance is usually increased in hypertensive individuals. Normally, the autonomic nervous system, kidneys, adrenal cortex, local hormones, and cytokines regulate vascular resistance. Failure of the normal regulation of vascular resistance leads to hypertension. The failure can theoretically occur in any part of the regulatory system. Initially, overactivity of the sympathetic nervous system plays a major role in the development and maintenance of hypertension. The excessive activation of the renin-angiotensin system (RAS) or enhanced sensitivity to its primary effector, Ang II, contributes to the development and maintenance of hypertension. The fact that inhibitors of the formation of Ang II or its antagonists at the receptor level are highly useful antihypertensive drugs supports the likely involvement of RAS in the pathogenesis of hypertension. Since calcium ions...

International Society on Hypertension in Blacks ISHIB

ISHIB is a nonprofit organization dedicated to improving the health and life expectancy of ethnic populations in the United States and around the world. The organization was founded in Atlanta, Georgia, in 1986 to respond to the problem of high blood pressure among African Americans and has since broadened its mission to include the total spectrum of ethnicity and disease. ISHIB aims at stimulating research and clinical investigation disseminating scientific findings to aid in the understanding of differences in obesity, hypertension, and other health issues among ethnic groups promoting public awareness of the harmful effects of hypertension, especially among African Americans educating the public on ways to prevent the complications of hypertension and developing health-related programs to improve the quality of life and health expectancy in ethnic minority populations worldwide.

Hypertension

Adiponectin has also been associated with hypertension. In adiponectin-deficient mice, a high-fat and -sucrose diet led to increased blood pressure (BP) (63). Although an initial study in humans reported that hypertensive males had increased plasma levels of adiponectin (64), subsequent studies reported that BP has a negative correlation to adiponectin (65-67). However, more recent data adjusting for insulin sensitivity did not show any significant correlation with hypertension and adiponectin, indicating that insulin resistance may mediate the potential association between adiponectin and BP (68). However, adiponectin has been associated with a vasodilatory response (63), with recent evidence suggesting that adiponectin increases NO formation through AMPK (55). Further studies are needed to elucidate more completely adiponectin's role in regulating BP levels.

High Blood Pressure

High blood pressure, or hypertension, increases your chances of developing heart disease or kidney disease and of having a stroke. About one in every four American adults has high blood pressure but may not be aware of it. It is often called the silent killer because it usually causes no symptoms. However, high blood pressure is easy to diagnose, and there are practical steps you can take to bring your blood pressure under control. Different activities make your blood pressure rise or fall. For example, normally, blood pressure rises when you are exercising and falls when you are resting. A blood pressure reading of 140 90 mm Hg or lower is generally considered normal. High blood pressure is classified according to guidelines that reflect the levels at which blood pressure begins to pose significant health risks. Normal blood pressure Lower than 130 mm Hg High-normal blood pressure 130 to 139 mm Hg High blood pressure A diagnosis of high blood pressure is based on two or more blood...

The Scope of the Problem

Like Horace, millions of Americans have reduced kidney function (that is, kidney failure), and don't know it. At least 6 million people have an elevated blood level of creatinine, a likely sign of kidney failure. Among older people with diabetes or hypertension (which includes the majority of older people), 1 in 8 has kidney disease. Among noninstitutionalized adults in the U.S., 1 in 10 has either an abnormal amount of protein in their urine or reduced kidney function, or both. Americans of all ages have kidney failure, especially older people, blacks, and Native Americans.

Electrolyte Abnormalities Sodium

Hyponatremia is a common finding in the surgical patient and is usually the result of excessive administration of H2O or hypotonic fluids. Patients may be symptomatic with levels < 130 mEq L and develop seizures < 120 mEq L. The presentation is with muscle twitching, increased DTRs, increased ICP, convulsions, hypertension, increased salivation, watery diarrhea, oliguria. In many cases there are

Discharge And Home Healthcare Guidelines

Metabolic acidosis, a pH below 7.35, results from any nonpulmonary condition that leads to an excess of acids over bases. Renal patients with chronic acidemia may show signs of skeletal problems as calcium and phosphate are released from bone to help with the buffering of acids. Children with chronic acidosis may show signs of impaired growth. Metabolic alkalosis, a pH above 7.45, results from any nonpulmonary condition that leads to an excess of bases over acids. Metabolic alkalosis results from one of two mechanisms an excess of bases or a loss of acids. Patients with a history of congestive heart failure and hypertension, who are on sodium-restricted diets and diuretics, are at greatest risk for metabolic alkalosis. Metabolic alkalosis can also be caused by prolonged vomiting, hyperaldosteronism, and diuretic therapy.

Diagnoses And Diagnostic Criteria

The diagnosis of other conditions is based on the measurement of a specific attribute. For example, the diagnosis of hypertension is made when measurements of blood pressure are observed to exceed a certain threshold. For the diagnosis to be reliable, there must be consensus on where the threshold for defining hypertension lies. Diabetes is another condition where measurement of an attribute in this case blood glucose level is compared with a threshold value considered by consensus to be normal.

Modeling The Diagnostic Process And The Establishment Of Standardized Diagnostic Criteria

Diagnostic criteria are usually based on traditional teaching that may be influenced through time by the literature. The literature often reflects an informal distillation of diagnostic concepts held by clinical experts in the field. However, a few examples exist where an ad hoc declaration of diagnostic criteria for a condition have been widely accepted. For instance, the Jones criteria for the diagnosis of rheumatic fever, although revised intermittently (6), have been the accepted standard for the identification of this disease entity for more than 50 years (7). Other examples include the criteria used for the diagnosis of essential hypertension (8) and systemic lupus erythematosus (9,10).

The Benefits of Exercise

Along with a healthy diet, exercise is the cornerstone of good health. Physical activity produces a multitude of benefits for your overall health and well-being. Being active helps prevent heart disease and stroke by lowering cholesterol levels and making the heart pump more efficiently. It reduces the risk of dying prematurely, especially of heart disease. Physical activity helps control your weight and prevent obesity, which is a risk factor for high blood pressure and diabetes. Regular exercise also can improve your mood, reduce stress, and relieve depression, not to mention build muscular strength and tone, increase your flexibility, If you are just starting an exercise program and have been inactive, ask your doctor to recommend activities that are safe, especially if you have an existing health problem such as diabetes or high blood pressure. Men who are already fit should add other types of exercises to their aerobic routine. Strength-conditioning exercises using free weights...

The Hazards of Tobacco

If you smoke, you will notice the gradual onset of a host of long-term problems. Your senses of smell and taste will weaken, you will get more frequent colds than before, facial wrinkling will intensify, and you will develop a nagging smoker's cough, which is actually a symptom of a serious disease called chronic bronchitis (see page 246). You also increase your chances of developing cancers of the lung and other organs, emphysema, high blood pressure, stroke, and heart disease. You also place your family at risk of the same health problems by exposing them to secondhand smoke (see page 31). Several products containing nicotine are available today to help you stop smoking, including nicotine gum, the nicotine patch, and the nicotine inhaler. Both the patch and the gum are available over-the-counter, while the inhaler requires a doctor's prescription. All three methods put nicotine into your system to help you curb your craving for tobacco and, when used according to directions, can...

Clinical Development Plan

In the pharmaceutical industry clinical development of a pharmaceutical entity starts with seeking alternatives or new drug therapies for an existing health problem (e.g., hypertension) or a newly identified health problem (e.g., AIDS). The health problem of interest may be related to virus, cardiovascular, cancer diseases, or other diseases. Once the health problem is selected or identified, whether it is worth developing an alternative or a new pharmaceutical entity for this particular disease is a critical development decision point. A clear decision point can increase the success of the project and consequently reduce the risk and cost. Suppose that it is decided to proceed with the development of a pharmaceutical

Primary Nursing Diagnosis

Signs of withdrawal, such as irritability, anxiety, tremors, restlessness, confusion, mild hypertension (blood pressure > 140 90), tachycardia (heart rate > 100), and a low-grade fever (temperature > 100 F). Keeping the patient safe during the withdrawal process depends on managing the physiological changes, the signs and symptoms, and the appropriate drug protocols. The goal is to keep the patient mildly sedated or in a calm and tranquil state but still allow for easy arousal.

Gender Ethnicracial And Life Span Considerations

The onset of DAT may occur at any age but is rare before age 50 the average onset occurs after age 65. Approximately 3 of men and women ages 65 to 74 have AD, and some scientists note that about 50 of those age 85 and older may have AD. The prevalence of AD doubles every 5 years beyond age 65. More females than males have the disease. It is difficult to determine if there are racial and ethnic differences in the prevalence of AD. However, a unique issue for older black African Americans is that, contrasted with other ethnic racial groups, they are disproportionately affected by stroke, high blood pressure, and diabetes. These diseases can increase the risk of developing AD.

Client Family Teaching

Several antihypertensive agents cause sedation which can be intensified with the addition of an opioid analgesic or benzodiazepine. Use caution when doing anything that requires thought or concentration, such as operating heavy machinery, driving a car, or taking care of children. 8. Several antihypertensive agents can cause gastrointestinal (GI) irritation which can be intensified with the addition of a nonsteroidal anti-inflammatory drug. Take the medication with food or milk to help avoid or minimize GI discomfort.

Descriptive And Inferential Statistics

After the completion of the study, descriptive statistics are useful tools to reveal possible clinical differences (or effects) or trends of study drugs. As an example, Table 2.5.1 provides a partial listing of individual patient demographics and baseline characteristics from a study comparing the effects of captopril and enalapril on quality of life in the older hypertensive patients (Testa et al., 1993). As can be seen from Table 2.5.1, although as a whole, the patient listing gives a detailed description of the characteristics for individual patients, it does not provide much summary information regarding the study population. In addition descriptive statistics for demographic and baseline information describe not only the characteristics of the study population but also the comparability between treatment groups (see Table 2.5.2). In addition, for descriptive purposes, Table 2.5.3 groups patients into low, medium, and high categories according to the ranking of their...

Are You at Risk for Kidney Failure

Most people who have early kidney failure are unaware of their condition because of the notable lack of symptoms in the early stages. (We discuss symptoms in Chapter 3.) This is true in the case of other diseases too (like diabetes and hypertension) but is particularly common in kidney disease. So those people who are at risk for kidney failure, either because of inherited susceptibilities or risky behaviors, should be aware of the possibility of contracting a kidney problem. In Chapter 3 we discuss how easy it is to discover the presence of kidney disease by utilizing a simple at-home test, but first let's find out whether you fall into one of the at-risk groups.

Palliative and Causative Acting Drugs

By far the largest fraction of today's pharmacopoeia does not target disease at its cause - as these causes are largely unknown - but by modulating a pathway that affects the disease-relevant phenotype or function. We refer to such drugs as symptomatic or palliative agents. The pathways they target are known from more than a century of physiological, biochemical, and pharmacological research. The pathways they modulate are disease phenotype-relevant (albeit not disease cause-relevant), and while they are not dysfunctional, their modulation can effectively be used to counterbalance the effect of a dysfunctional, disease-causing pathway. Thus signs and symptoms of the disease can be alleviated, often with striking success, notwithstanding the fact that the real cause of the disease remains untouched. A classical example of such an approach is the acute treatment of thyrotoxicity with b-adrenergic-blocking agents even though in this case the sympathetic nervous system does not contribute...

Clinical Significance And Clinical Equivalence

The magnitude of a clinically significant difference varies. In practice, no precise definition exists for the clinically significant difference, which depends on the disease, indication, therapeutic area, class of drugs, and primary efficacy and safety endpoints. For example, for antidepressant agents (e.g., Serzone), a change from a baseline of 8 in the Hamilton depression (Ham-D) scale or a 50 reduction from baseline in the Hamilton depression (Ham-D) scale with a baseline score over 20 may be considered of clinical importance. For antimicrobial agents (e.g., Cefil), a 15 reduction in bacteriologic eradication rate could be considered a significant improvement. Similarly, we could also consider a reduction of 10 mm Hg in sitting diastolic blood pressure as clinically significant for ACE inhibitor agents in treating hypertensive patients. The examples of clinical significance on antidepressant or antihypertensive agents are those of individual clinical significance, which can be...

Diseases That Lead to an Increased Risk of Kidney Failure

Sometimes it's the diseases you already have that can cause trouble for your kidneys. The most common culprits include diabetes and hypertension. A few patients develop kidney failure secondary to potassium deficiency. Hypertension High blood pressure is one of the most common disorders in the United States. The majority of people over 50 suffer from it. Thanks to a persistent campaign by the American Heart Association and others, the importance of controlling blood pressure is more and more widely known, and most patients now get at least some treatment for hypertension. Undertreated or untreated, hypertension can lead to heart failure, strokes, and kidney failure. It was widely assumed in the past that hypertension causes kidney failure. However, a recent analysis of 10 large trials shows that controlling blood pressure in nonmalignant hypertension (the commonest kind) doesn't make any difference in the development of kidney failure. Among 26,521 people with high blood pressure...

Medical Implications of OSA

Severe cardiovascular disease is also common in patients with OSA. Hypertension, cardiac arrhythmia, left ventricular dysfunction, myocardial infarction, pulmonary hypertension, stroke, and sudden death are all more common in patients with this condition.10 Systemic hypertension has been reported in up to 50 of patients with OSA, and one report implicated undiagnosed OSA in as many as 40 of patients with essential systemic hypertension.11 In an often quoted study by He et al.12 in 1988, a large cohort of patients with OSA were evaluated at the Henry Ford Hospital Sleep Disorders Center and followed for up to 9 years. Untreated subjects with an AHI of > 20 had significantly increased mortality compared with those with less severe AHI scores. Aggressive treatment with nasal continuous positive airway pressure (CPAP) appeared to reverse this trend, clearly implicating OSA for the increased mortality.

Statistical Considerations

For a clinical trial, it is recognized that it is impossible to address all questions with one trial. Therefore, it is important to identify the primary and secondary response variables that will be used to address the scientific and or medical questions of interest. The response variables (or clinical endpoints) are usually chosen at the outset, since they are needed to fulfill the study objectives. Once the response variables are chosen, the possible outcomes of treatment are defined, and those showing efficacy and safety are clearly indicated. In practice, it is suggested that the selected clinical endpoints be validated (reliable and reproducible), widely available, understandable, and accepted. For example, in an antibiotic trial the outcome might be defined as cure, cure with relapse, or treatment failure, and the response variables may be pyrexia, dysuria, and frequency of urination. The criteria for the evaluation of a cure could be that all signs or symptoms of urinary tract...

Transient Global Amnesia

These are features (see Table 55) that caution against, but do not firmly exclude, a diagnosis of frontotemporal lobar degeneration (FTLD). A history of alcohol abuse raises the possibility of an alcohol-related basis for a frontal lobe syndrome. However, excessive alcohol intake may also occur in patients with frontotemporal dementia (FTD) as a secondary manifestation of social disinhibition or hyperoral tendencies. The presence of vascular risk factors, such as hypertension, ought to alert investigators to a possible vascular etiology. Nevertheless, such risk factors are common in the general population and may be present coincidentally in some patients with FTLD, particularly in those of more advanced age.

Example The Pawtucket Health Heart Program in Rhode Island is a com-munitywide cardiovascular disease prevention program employing a variety of community-based interventions, targeting worksites, restaurants, schools, grocery stores, individuals, small groups, and the community at large in an effort to reduce the incidence of heart disease through screening, health education, and counseling programs directed toward risk factors such as high blood pressure, elevated cholesterol, cigarette smoking, obesity, and sedentary lifestyle (Hunt et al., 1990 Lasater et al., 1991).

Thrombolytic Therapy in Acute Myocardial Infarction

The beneficial effect of thrombolytic therapy in the treatment of acute myocardial infarction (AMI) is now well established 13-15 . Use of thrombolytic agents has become a standard emergency treatment in such situations to the extent that globally, such drugs are administered to over 500,000 patients each year. It has been estimated that three times that number could potentially benefit from such therapy 5,16 . Although effective, these products achieve complete reperfusion in, on an average, only 50 of patients, and side effects can include risk of hemorrhage (in particular intracranial bleeding) as well as hypertension.

The Health Risks of Being Overweight or Underweight

More than half of all American men are overweight, and a third of all American men are obese (weigh more than 20 percent more than their ideal body weight). Being overweight is a major risk factor for a number of chronic diseases, including heart disease, high blood pressure, stroke, diabetes, and certain forms of cancer. Even a small reduction as little as 10 percent in body weight can decrease your chances of developing the most common chronic disorders as you get older. If you already have a health problem, losing weight can help you manage your condition. In some disorders, such as diabetes, weight loss can help reduce and even eliminate the need for medication. Heart disease is the number one cause of death in American men. High blood pressure is a major risk factor for stroke, which can lead to permanent disability and death. You can reduce your risk of developing heart disease, high blood Healthy where your body stores fat. If you are like most men, your body stores fat around...

Multiplicity and ligand selectivity

EPHX2 is found in high levels in the mouse cytosol, from which the enzyme was originally purified. The enzyme contains an imperfect peroxisome-targeting sequence at the C-terminus and so activity has also been detected in peroxisomes. Like EPHX1, EPHX2 is encoded by a single gene, but there is very little sequence similarity between the two enzymes. EPHX2 is a known hydrate range of aliphatic and extensively substituted, hindered arene oxides. However, current focus is on its physiological role, especially the metabolism of arachidonic, linoleic, and other fatty acid epoxides. These endogenous chemical mediators play an important role in blood pressure regulation and inflammation. It has been proposed that inhibitors of EPHX2 might be useful in the treatment of hypertension or as antiinflammatory agents and several potent and selective amide, carbamate, and urea-based inhibitors of EPHX2 have been developed.87

Catechol Omethyltransferase

Catechol O-methyltransferase (COMT) typically metabolizes catecholamines and estrogens, forming mixtures of ortho and para methoxy metabolites118 Drug substrates include L-dopa, 2-hydroxy ethinylestradiol and isoproteranol and COMT inhibitors have therapeutic value in the treatment of Parkinsonism. The enzyme is the product of a single gene located on chromosome 22q11.2, but two forms of the protein exist soluble COMT (S-COMT, 25 kDa) and membrane-bound COMT (M-COMT, 30kDa), whose additional 50 amino acids provide the hydrophobic anchor for membrane localization. S-COMT predominates in peripheral tissues and M-COMT is the main form of the enzyme in brain tissue.119 COMT activity is inherited in an autosomal recessive manner. Individuals with low activity inherit a form of the enzyme that is thermolabile. A single G to A transition at codon 108 158 of the cytosolic membrane gene results in a Val to Met substitution which forms the molecular basis for the well-recognized interindividual...

Intraarterial Thrombus Formation A

Activation of platelets, e.g., upon contact with collagen of the extracellular matrix after injury to the vascular wall, constitutes the immediate and decisive step in initiating the process of primary hemostasis, i.e., cessation of bleeding. However, in the absence of vascular injury, platelets can be activated as a result of damage to the endothelial cell lining of blood vessels. Among the multiple functions of the endothelium, the production of NO' and prostacyclin plays an important role. Both substances inhibit the tendency of platelets to adhere to the endothelial surface (platelet adhesiveness). Impairment of endothelial function, e.g., due to chronic hypertension, cigarette smoking, chronic elevation of plasma LDL levels or of blood glucose, increases the probability of contact between platelets and endothe-lium. The adhesion process involves GPIB IX, a glycoprotein present in the platelet cell membrane and von Wille-brandfs factor, an endothelial membrane protein. Upon...

Initial treatment of atrial fibrillation

In patients without rheumatic heart disease who are younger than 75 years of age, warfarin therapy should be initiated if risk factors are present, including previous transient ischemic attack or stroke, hypertension, heart failure, diabetes, clinical coronary artery disease, mitral stenosis, prosthetic heart valves, or thyrotoxicosis. In patients

Generalization Of Controlled Randomized Trials

Note that the current conduct of clinical trials is to compare the difference in distributions of the clinical responses observed from patients under a test therapy and a standard (or reference) therapy or a placebo. This concept is referred to as population efficacy (or safety). Suppose that the distribution of a clinical response can be adequately described by a normal probability distribution. Then the population efficacy can be assessed through the comparison of the first two moments of the distributions between the test and the reference therapies. This is because a normal distribution is uniquely determined by its first two moments. The comparison of the first moment of the efficacy endpoints for the two therapies is usually referred to as average efficacy, while the comparison of the second moments is called the variability of efficacy. To provide a better understanding of average efficacy and variability of efficacy, the comparison in averages and variabilities are illustrated...

Hypertensive Emergency

Neurologic, cardiac, renal, or retinal dysfunction are present. Hypertensive emergencies include severe hypertension in the following settings C. Causes of secondary hypertension include renovascular hypertension, pheochromocytoma, cocaine use, withdrawal from alpha-2 stimulants, clonidine, beta-blockers or alcohol, and noncompliance with antihypertensive medications.

Cerebrovascular Accident

In an embolic CVA, a clot is carried into the cerebral circulation, usually by the carotid arteries. Blockage of an intracerebral artery results in a localized cerebral infarction. Hemorrhagic CVA results from hypertension, rupture of an aneurysm, arteriovenous malformations, or bleeding disorder. Risk factors thought to cause blood vessel changes that cause vessel walls to be more susceptible to rupture and hemorrhage include elevated low-density lipoprotein (LDL) and lowered high-density lipoprotein (HDL) levels, cigarette smoking, and a sedentary lifestyle.

Enalaprilat IV Vasotec

Enalaprilat is an ACE-inhibitor with a rapid onset of action (15 min) and long duration of action (11 hours). It is ideal for patients with heart failure or accelerated-malignant hypertension. F. Hydralazine is a preload and afterload reducing agent. It is ideal in hypertension due to eclampsia. Reflex tachycardia is common. The dose is 20 mg IV IM q4-6h. I. Phentolamine (Regitine) is an intravenous alpha-adrenergic antagonist used in excess catecholamine states, such as pheochromocytomas, rebound hypertension due to withdrawal of clonidine, and drug ingestions. The dose is 2-5 mg IV every 5 to 10 minutes.

What Kind Of Responses To Trauma Should Mental Health Practitioners Be Concerned About

In most discussions of long-term pathologic responses following a traumatic event, there is an implicit assumption that the critical outcome being referred to is PTSD. Yet, PTSD is but one among several possible outcomes following trauma exposure. Trauma survivors, compared to persons who have not experienced trauma, are at increased risk for the development of other mental disorders, such as major depression, panic disorder, generalized anxiety disorder, and substance abuse, as well as persistent anxiety symptoms and distress that do not meet criteria for a specific psychological disorder 3 . Furthermore, they are at risk for developing somatic symptoms and physical illnesses, particularly hypertension, asthma, chronic pain syndromes and other psychosomatic illnesses. Interestingly, the focus of most investigations in the wake of disasters that affect large numbers of persons, whether they be natural or man-made events, has been related to PTSD, even though this disorder is neither...

Regional Differences and Variability in Left Ventricular Wall Motion

In our understanding of the mechanical performance of the heart as a pump we mostly rely on the famous studies of Otto Frank1 and Ernest Starling2 whose observations have been widely accepted for a century. Thus, the clinical therapeutic regimens contain volume substitution (preload), antihypertensive therapy (afterload), bradycardic agent (heart rate) and positive inotropic agent (contractility) drug administration. All these maneuvers involve the heart as a whole. In most of our patients, however, just parts of the ventricle are injured by insufficient energy supply. Therefore, if we treat the ventricle as a whole we may ask whether all the parts of the ventricle act in unison. When we look at heart preparations for morphological analyses (Fig. 5.1) it becomes obvious from the global as well as local anisotropy that there must be an inhomogeneity in myocardial contraction i) across the ventricular wall, ii) from site to site from apex to the base, and, moreover, iii) at any site...

Pharmacologic Highlights

Other Drugs Antihypertensives are also used since hypertension increases stress on damaged blood vessels. A direct vasodilating agent such as hydralazine or sodium nitroprusside may also be used. Angiotensin-converting enzyme inhibitors (ACEIs) are used to lower blood pressure.

Cardiovascular Anomalies

Cardiovascular anomalies are the most common birth defects in man, accounting for 0.5-1 of live births. They are typically classified according to the affected segment of the heart. The complexity of an anomaly, its relationship to other cardiac structures, and its physiologic consequences, determine its clinical significance. Ventricular and atrial septal defects are the two anomalies most commonly seen and can produce a spectrum of problems, including congestive heart failure and pulmonary hypertension (1). Abnormal atrioventricular valves, such as found in tricuspid atresia or congenital mitral stenosis, are associated with underdevelopment of either the right or left ventricle, respectively, and have more severe clinical implications. Maldevelopment of either the aorta or the pulmonary artery leads to conditions such as tetralogy of Fallot, double-outlet right ventricle, and transposition of the great arteries. All of these congenital anomalies require surgical intervention for...

Outcomes in Diabetic Patients

An underlying question regarding the vascular protective effects of antihypertensive therapies is whether these effects are mediated via the reduction in BP or whether these drugs may provide additional effects. This issue has been addressed in a number of studies. Comparisons of antihypertensive therapies on cardiovascular outcomes in hypertensive patients with type 2 diabetes have been performed in several trials. In the United Kingdom Prospective Diabetes Study, the effects of tight and less tight BP control by the ACE inhibitor captopril or the -blocker atenolol were compared in patients with both hypertension and type 2 diabetes (9,93). This prospective study demonstrated that tight BP control was more effective than less tight control in reducing macrovascular endpoints, including stroke and deaths related to diabetes (9,93). Additionally, this study indicated that the ACE inhibitor and -blocker were equally effective in reducing cardiovascular outcomes. The Appropriate Blood...

Description Medical Diabetes

Long-term complications such as disease of the large and small blood vessels lead to cardiovascular disease (coronary artery disease, peripheral vascular disease, hypertension), retinopa-thy, and renal failure. Diabetic patients also have nerve damage (neuropathy) that can affect the peripheral nerves, resulting in numbness and pain of the hands or feet.

Hypolipidemic 3thia Fatty Acids

In addition to lowering plasma TG, n-3 fatty acids (eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) are reported to have a number of additional beneficial effects on the cardiovascular system which include antihypertensive and antithrombotic actions.3-5 EPA and DHA are major fatty acid constituents of fish oil and it has been assumed that both EPA and DHA are responsible for its hypotriglyceridemic activity. However, growing evidence indicates that EPA and DHA may possess different hypolipidemic properties. We have reported that EPA is the fatty acid primarily responsible for the TG-lowering effect of fish oil (Table 1), but the mechanism underlying this hypotriglyceridemic effect has not yet been fully elucidated. Interestingly, however, we

Pressure and Hemodynamic Effects

The BP effects of Ang II are mediated via a combination of mechanisms including vasoconstriction, stimulation of renal tubular sodium resorption, and its effects on the central and sympathetic nervous tissues (100,101). Because hypertension exacerbates diabetic vascular complications (102), it is likely that the BP-lowering effects of ACE inhibitors are a major contributor to the reduction of vascular complications in diabetic patients with hypertension (9,93). However, there is growing evidence that ACE inhibitors may also provide beneficial vascular effects in diabetes in the absence of systemic hypertension. Several large studies have demonstrated that ACE inhibition can reduce renal, retinal, and cardiovascular complications in normotensive diabetic patients (1,5,8). Although a small reduction in systemic BP within the normotensive range may contribute to the vasoprotective effects of ACE inhibition, the magnitude of these effects is greater than that which would be predicted...

Clinical Manifestations

Acute cardiovascular Tachycardia, hypertension, tachyarrhythmias, myocardial infarction (MI), vascular endothelial damage and platelet aggregation and adhesion, subacute bacterial endocarditis (SBE) from septic emboli. Chronic cardiovascular Coronary artery disease (CAD) and left ventricular hypertrophy (LVH) dilated cardiomyopathy, peripheral vascular disease, and acute aortic dissection. Pulmonary Pneumomediastinum from deep inhalation with breath-holding, noncardiogenic pulmonary edema (NCPE) may result from adrenergic tone, pulmonary capillary leak, and pulmonary hypertension.

Pharmacology Of Alcohol

More important than the disruption of the cell membrane is the effect of alcohol on the gamma-aminobutyric acid (GABA) system and glutamate system of the brain. The brain has three types of GABA receptors A, B, and C. GABA A receptors are the targets for alcohol, benzodiazepines, barbituates, and neurosteroids. Stimulation of the GABA receptor by the binding of these compounds causes an ion channel to open temporarily and emit chloride ions into the cell. Alcohol enhances the influx of chloride ion, and the result is sedative and anxiolytic effects. Chronic use of alcohol down-regulates the GABA system, and the neuron eventually becomes dependent on alcohol to enable GABA to function. If alcohol is withdrawn, the opening of the chloride ion channel fails, because GABA is no longer capable of performing the task secondary to the cell, having adapted to the role of alcohol. Thus, the cell becomes hyperexcitable, leading to irritability, insomnia, hypertension, tachycardia, and possibly...

And Insulin Sensitivity

There is growing evidence that inhibition of the RAS system by either ACE inhibition or ATI receptor antagonism can increase insulin sensitivity and glucose utilization. Studies using euglycemic hyperinsulinemic clamps have shown that ACE inhibitor treatment improves insulin sensitivity in most (136-140), but not all (141,142) individuals with hypertension, obesity, and or type 2 diabetes. Similarly, although ATI antagonism has been reported to improve muscle sympathetic nerve activity and insulin sensitivity in obese hypertensive subjects (143) and increase basal and insulin-stimulated glucose oxidation in normotensive individuals with type 1 diabetes (144), other clinical studies have not observed improvement on insulin sensitivity and glucose homeostasis following treatment with ATI receptor antagonists (139,145,146).

Vicious circle of the progression of nephropathy

Damage caused by high blood pressure , More protein deposits in the corpuscles Since this is not yet possible, patients and doctors must all try to reduce, or at least to retard, kidney damage via the factors that we can influence. The most important is good blood sugar control and good management of high blood pressure. Sometimes, it is helpful to eat less protein. If that is not enough, protein excretion in the urine and its detrimental effects can be treated with special medicines. Levels of blood fats should not be too high and intensive management of the diabetes should be started as soon as possible. Another factor that increases the risk of kidney damage is smoking, so giving up is a helpful step to take.

Peroxisome Proliferator Activated Receptory Key Regulator of Adipogenesis and Insulin Sensitivity

PPAR-y was first identified as a part of a transcriptional complex essential for the differentiation of adipocytes, a cell type in which PPAR-y is highly expressed and critically involved (6). Homozygous PPAR-y-deficient animals die at about day 10 in utero as a result of various abnormalities including cardiac malformations and absent white fat (7-9). PPAR-y is also involved in lipid metabolism, with target genes such as human menopausal gonadotropin coenzyme A synthetase and apolipoprotein (apo)-A-I (10,11). Chemical screening and subsequent studies led to the serendipitous discovery that thiazolidinediones (TZDs) were insulin sensitizers that lower glucose by binding to PPAR-y. Used clinically as antidiabetic agents, the TZD class includes pioglitazone (Actos) and rosiglitazone (formerly BRL49653, now Avandia) (12,13). Troglitazone (ReZulin) was withdrawn from the market because of idiosyncratic liver failure. Naturally occurring PPAR-y ligands have been proposed, although with...

Metabolic derangements that accompany liver failure

Ascites due to portal hypertension and or hypoalhuminemia. Ascites can be detected on physical exam by shifting dullness or a positive fluid wave. Possible complication is 8. Portal hypertension seen with cirrhosis (chronic liver disease) causes hemorrhoids, varices, caput medusae.

Cardiovascular System

Transient hypertension is noted in nearly 50 of alcoholics undergoing detoxification and is related to quantity of drinking and severity of other withdrawal symptoms. Epidemiological studies have demonstrated that alcohol elevates blood pressure independently of age, body weight, or cigarette smoking (Klatsky, Friedman, & Armstrong, 1986). A 10-year follow-up study found even moderate intake of alcohol (< 23 grams day) significantly increased the risk for hypertension in men, independent of age and body mass index. The risk of hypertension was increased for women, but not significantly, when age and body mass index were controlled (Ohmori et al., 2002). Heavy alcohol intake (> 60 grams day) is associated with increased risk of ischemic and hemorrhagic stroke. Mechanisms involved include alcohol-induced hypertension, coagulation disorders, atrial fibrillation, and reduction in cerebral blood flow (Reynolds, Lewis, Nolen, Kinney, & Sathya, 2003). Alcohol has been shown...

Investigating the scene of death

There must also be an awareness that people with natural disease may, intentionally or not, abuse drugs which may exacerbate their underlying disease process and significantly contribute to their death. Drugs create pathological states, with or without death, by their immediate pharmacologic effects, the way in which the drug is taken, by the cumulative effects of chronic abuse, and by interaction with pre-existing pathologic conditions.1,2 Therefore, what once could have been discussed as a complication of hypertension (e.g., spontaneous aortic dissection) must now be evaluated as a possible effect of acute and chronic cocaine abuse.3,4

Diffuse Liver Disease

The role of imaging in cirrhosis is to identify effects of portal hypertension and to detect HCC. The liver in early cirrhosis often has a normal appearance on CT. Early CT features include hepatomegaly and heterogeneity of hepatic parenchymal attenuation. Advanced cirrhosis is characterized by decreased hepatic volume with prominence of the porta hepatis and intrahepatic fissures, decreased size of the right hepatic lobe and medial segment of the left lobe, with a corresponding relative increase in the size of the caudate lobe and left lateral segment 28 . Regenerative nodules are seen on CT in those patients with siderotic nodules (dense on unenhanced CT, and signal void on MRI) and are better appreciated on MRI than on CT due to greater MR susceptibility to iron 29 . Dysplastic nodules (DN) represent a continuum and transition between regenerative nodules and HCC, and therefore is an important imaging diagnosis. When large, they are characteristically hyperintense on Tl-weighted...

There are few absolute contraindications for deep peeling, with the exception of physical or mental instability. During pregnancy and lactation any cosmetic intervention is considered to be undesirable. We have safely peeled patients with hypertension, diabetes mellitus, thrombo-cytopenia, thyroid malfunction, etc., as long as their disease is well controlled and stable. All pa

Glucocorticoid Therapy

With short-term use, glucocorticoids are practically free of adverse effects, even at the highest dosage. Long-term use is likely to cause changes mimicking the signs of Cushing's syndrome (endogenous overproduction of cortisol). Sequelae of the anti-inflammatory action lowered resistance to infection, delayed wound healing, impaired healing of peptic ulcers. Sequelae of exaggerated glucocor-ticoid action a) increased gluconeogen-esis and release of glucose insulin-dependent conversion of glucose to triglycerides (adiposity mainly noticeable in the face, neck, and trunk) steroid-diabetes if insulin release is insufficient b) increased protein catabolism with atrophy of skeletal musculature (thin extremities), osteoporosis, growth retardation in infants, skin atrophy. Sequelae of the intrinsically weak, but now manifest, mineralocorticoid action of cortisol salt and fluid retention, hypertension, edema KCl loss with danger of hypokalemia.

Genetic Considerations

HF is a complex disease combining the actions of several genes with environmental factors. Many HF risk factors have genetic causes or are associated with genetic predispositions. These include hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM), coronary artery disease, myocardial infarction, and hypertension. Genetic polymorphisms of the renin-angiotensin-aldosterone system (RAAS) and sympathetic system have also been associated with susceptibility to and or mitigation of HF. Gene variants in the alpha-2c adrenoceptor and the alpha-1 adrenoceptor have been associated with a higher risk of HF among African Americans.

Age Related Macular Degeneration

Elevation of IOP results from a deposition of extracellular matrix (ECM) in the anterior chamber, and thus blockage of the AH drainage pathway, the TM and Schlemm's canal. The ECM is composed of numerous proteins, modified glycoproteins, and glycosaminoglycans, including hyaluronic acid, chondroitin sulfate, dermatan sulfate, keratin sulfate, and heparin sulfate. The abnormal deposition and or clearance of ECM in glaucomatous patients may also result from TM cell death and loss of phagocytic activity during the aging process. Coupled with these phenomena is perhaps the decreased ability of TM cells to liberate local matrix metalloproteinases (MMPs), that can digest the ECM and remodel and maintain the anterior chamber architecture and function. There is increasing evidence that increased concentration of tissue growth factor- 2 (TGF-P2) observed in ocular hypertensive glaucoma patients contributes to the elevation of ECM in the TM. The loss of MMP activity could also be due to TGF-...

Clinical Trial Issues

From an efficacy perspective, clinical trials of ocular hypotensive agents can be relatively short with well-defined endpoints of IOP reduction following once or twice daily dosing. However, recruitment of glaucoma and ocular hypertensive patients and the provision of the NCE in the correct formulation with reasonable shelf-life and stability are formidable challenges fraught with logistics issues and, ultimately, patient compliance.

Diabetes and fibrinolysis

Thus, people with type 2 diabetes exhibit a decreased fibrinolytic system capacity secondary to increased PAI-1 in blood. Similar derangements are evident in association with other states of insulin resistance and compensatory hyperinsulinemia in conditions such as obesity (94,95), hypertension (101), and the polycystic ovarian syndrome (100,102,103).

New Research Areas

While FP prostaglandin analog esters currently dominate the therapeutic scene for treatment of ocular hypertension and glaucoma, investigators are keen to discover new drugs that may supplant the prostaglandins and or be combined with the prostaglandins in the future. On the horizon are some new ocular hypotensive agents with a variety of mechanisms of action. These include protein kinase inhibitors such as rho kinase inhibitors (e.g., Y-27632)71 myosin-II ATPase inhibitor (blebbistatin)72 5HT2 receptor agonists (a-methyl-5HT AL-34662) adenosine agonists (2-alkynyladenosine) diadenosine polyphosphates73 calcium antagonists (nivaldepine and flunarizine)74 an angiotensin AT1 receptor antagonist (CS-0 88)75 5HT1A agonists76 melatonin agonists74 dopamine agonists (PD128907, 3-PPP, CHF1035, and CHF10 24)77 agents that degrade glyocosaminoglycans (AL-3037A)78 cannabinoid agonists79 natriuretic peptides80 marine macrolides (e.g., latrunculins and bumetamide)2 chloride transport inhibitors...

Summary and Perspective

While carvedilol has proven itself in the cardiology community, and has become a significant financial success, the full potential of the drug may still not yet be realized. The multiple organ protection that carvedilol has demonstrated in preclinical studies suggests the potential for carvedilol to provide 'best in class' therapy for hypertension (for which it also is approved), angina and organ damage failure, including the renal, vascular, and central nervous systems.

Soon After The Earthquake

After 1 week, the focus of health care was shifted from emergency medical care to care for chronic patients, including those with hypertension, diabetes mellitus, and mental disorders 4,5 . Care for demented elderly and mentally handicapped people in shelters posed difficult problems. Insomnia was common at crowded shelters. Acute stress responses and nightmares were reported. Psychiatric emergency care was established at some shelters. The Hyogo Prefectural Mental Health Center played a key role in coordinating mental health care to victims.

Therapeutic implications

Several complications and concomitants of diabetes can exacerbate a prothrombotic state and accelerate vascular disease. Thus, hypertriglyceridemia, hypertension, and hyperglycemia must be ameliorated. Lipid-lowering drugs should be used vigorously as is evident from results from studies such as the CARE trial in which the incidence of CAD was reduced by 27 in diabetic subjects to an extent comparable to that in nondiabetic subjects by administration of pravastatin over 5 years of follow-up (138). Hypertension should be treated vigorously, generally with angiotensin-converting enzyme inhibitors because of the demonstrated reduction of progression of renal disease accompanying their use. An alternative may be angiotensin receptor blocking agents. Despite the ominous portent of macrovascular disease in type 2 diabetes, nephropathy continues to be a dominant life-threatening complication with an extraordinarily high incidence. Its occurrence is clearly related to hyperglycemia and may...

Longterm Health Consequences

A wide range of physical and psychological problems have been observed among victims even several years after the earthquake. These problems were mainly related to stressful experiences and conditions of the victims. However, other environmental factors and direct physical damage also played an important role. For example, hypertension among victims could be caused by several causes such as salty instant food, stressful living conditions, and nightmares. It will take a long time to obtain data on such possible effects of the earthquake as those on the psychosocial development of children, and those on the immune function (and on the incidence of allergy, cancer, etc.). The isolated lifestyle increased alcohol use and cigarette-smoking, thus increasing the risk of hypertension and coronary heart disease. The lack of intake of fresh vegetables and the increased intake of ''fast food'' increased

What Is Blood Pressure

People with high blood pressure vary dramatically in their sensitivity to salt. Some show big changes in blood pressure with minor changes in salt intake others do not. Older people, African Americans, and those with family histories of hypertension will experience the biggest drop in blood pressure when they limit their salt intake.

Spontaneous Intracerebral Hemorrhage

Spontaneous intracerebral hemorrhage (ICH) accounts for approximately 10 of cases of stroke. Arterial hypertension is by far the most common cause of ICH other causes are the intracranial aneurysms, vascular malformation, bleeding diathesis, cerebral amyloidosis, brain tumors, vasculitis, or drug abuse.

Chronic Renal Failure Introduction

Mg++ increases, and reduced Hgb and Hct that result in metabolic acidosis, anemia, growth retardation, hypertension, and bone demineralization. Eventually, if untreated, uremic syndrome develops as the kidneys are not able to maintain fluid and electrolyte balance. End stage renal disease (ESRD) is defined as loss of kidney function at 90 or greater. ESRD is the term applied when the kidneys are no longer able to clear wastes from the body. Eventually the disease terminates in death unless kidney transplantation or dialysis is performed.

Measuring Your Own Blood Pressure

All patients with kidney disease should learn to measure their own blood pressure in the arm how often they need to take the measurement depends on whether it is high or not if it is normal, check it at least once a month to make sure it stays that way. If you have high blood pressure, check it and record it at least once a week, at about the same time of day. Show your blood presssure log to your doctor. If your blood pressure is consistently elevated, or if protein is consistently in your urine, see your doctor. Current recommendations are to keep mean arterial blood pressure (systolic pressure plus two times diastolic pressure, divided by three) under 95 mm Hg in patients with renal failure. This is lower than has been recommended in the past. A blood pressure of 130 80, for example, signifies a mean arterial pressure of 97 mm Hg and is slightly high. Pronounced hypertension (say, over 160 100) can not only damage the If you have high blood pressure, check it and record it at least...

Repair of Hypoplastic Right Ventricular Outflow Tract

Residual Right Outflow Tract Obstruction

In the presence of right heart hypertension, the chance of late development of a pericardial outflow tract aneurysm can be reduced further by attaching a synthetic patch to the surface of the previously placed pericardial patch. This synthetic patch is cut from a tubular Dacron graft, which incites a fibrous tissue reaction, resulting in a thick protective outer surface over the pericardial patch. Figure 9-40. In the presence of right heart hypertension, the chance of late development of a pericardial outflow tract aneurysm can be reduced further by attaching a synthetic patch to the surface of the previously placed pericardial patch. This synthetic patch is cut from a tubular Dacron graft, which incites a fibrous tissue reaction, resulting in a thick protective outer surface over the pericardial patch.

Scope of the Metabolic Syndrome Epidemic Prevalence and Risk

In several countries, MetS prevalence by any definition has been reported to rise from greater than 10 in adults aged 20-40 years up to 40-70 in adults aged over 60.13'14 Among patients with hypertension, between a third and a half will concurrently have MetS, at least if hyperinsulinemia is considered as the defining biochemical feature.15-17 The risk of having MetS is most tightly linked to obesity MetS prevalence increases to greater than 50 in both obese MetS is associated with increased risk of cardiovascular disease and also increased risk for the development of its associated risk factors - diabetes and hypertension. The presence of MetS according to the National Cholesterol Education Program (NCEP) definition was prospectively associated with the development of type 2 diabetes20 (see 6.19 Diabetes Syndrome X) and both all-cause and cardiovascular mortality.21 Cardiovascular disease risk has been reported to be increased two- to fivefold in both men and women with MetS (greater...

Glomerulonephritis Introduction

Acute glomerulonephritis (AGN) is an alteration in renal function caused by glomerular injury, which is displayed by the classic symptoms of gross hematuria, mild proteinuria, edema (usually periorbital), hypertension, and oliguria. AGN is also classified as either a primary disease, associated with group A, beta-hemolytic streptococcal infection or a secondary disease, associated with various systemic diseases (i.e., systemic lupus erythema, sickle cell disease, Henoch's chorea purpura). The most common type of AGN is the primary disease, described as an immune-complex disease (or an antigen-antibody complex formed during the streptococcal infection which becomes entrapped in the glomerular membrane, causing inflammation 8 to 14 days after the onset of this infection). AGN is primarily observed in the early school-age child, with a peak age of onset of 6 to 7 years. The onset of the classic symptoms of AGN is usually abrupt, self-limiting (unpredictable), and prolonged hematuria and...

Etiology of Metabolic Syndrome The Search for the Single Causal Mechanism

Initial interest focused on the direct effect of insulin on vascular function and the impact of insulin resistance. Insulin mediates a direct vasodilator effect on a range of vascular beds, both arterial and venous.24'25 The effect has been predominantly related to activation of nitric oxide synthase activity,26 - although other endothelial mechanisms have also been suggested.26 Further, insulin's vasodilator effect has been suggested to be an important determinant of the extent of glucose uptake in skeletal muscle.27 Further studies indicated that resistance to the vascular effects of insulin paralleled systemic insulin resistance in diabetes and in hypertension as well as with obesity.28 Also, modalities that improve systemic insulin resistance (e.g., angiotensin-converting enzyme inhibitors, salt loading) also improve vascular insulin sensitivity.29,30 However, vascular insulin resistance ultimately could not be viewed as a specific cause of the vascular manifestation of MetS. In...

Genes and the Metabolic Syndrome Complex Trait Genetics

For instance, in certain North American aboriginal communities, such as the Oji-Cree of Ontario, the combined prevalence of impaired glucose tolerance and type 2 diabetes is approximately 40 .40 This development has been inextricably linked with the recent doubling of hospitalizations for coronary heart disease among Oji-Cree, despite declining rates in the general Canadian population.41 Among Oji-Cree adults aged 35 and older, 43 had MetS.42 Furthermore, 8.7 of female Oji-Cree adolescents had MetS, as defined by the NCEP Adult Treatment Panel (ATP) III47 criteria. Increased waist girth and depressed HDL cholesterol were the most prevalent individual components in subjects with MetS. Common functional polymorphisms in genes encoding proteins involved in the renin angiotensin system, the G-protein family (GNB3) and components of triglyceride-rich lipoproteins were each significantly associated with MetS in Oji-Cree adults, especially women.43 Such studies suggest that...

Insights into Metabolic Syndrome Progression from the Monogenic Disorders

Nondiabetic FPLD2 subjects have high plasma insulin, triglycerides, free fatty acids, and CRP, together with low plasma HDL cholesterol and adiponectin long before diabetes developed.43 Thus, the characteristic cluster of biochemical abnormalities precedes the relatively late decompensation of glycemic control among carriers predisposed to lipodystrophy. A similar pattern of progression - i.e., early hyperinsulinemia with dyslipidemia and altered adipocytokines followed by hypertension and finally diabetes - may be important in 'garden-variety' MetS. In both cases, spillover of FFA from adipose tissue and uptake and storage viscerally and in ectopic sites, such as muscle and liver, may be a key inciting pathophysiological event. In FPLD, spillover of free fatty acids occurs because there is an anatomical absence of the peripheral subcutaneous fat buffer. In 'garden-variety' MetS, this spillover occurs because peripheral fat stores become saturated. If this pattern of metabolic...
