Diagnostic Highlights


Normal Result

Abnormality with Condition


Lipid profile

Electrocardiogram (ECG)

Range varies for age and gender; 140-200 mg/dL

Normal electrocardiographic representation with P, Q, R, S, and T waves

Total cholesterol level above 200 mg/dL

Q waves because of a prior MI; resting ST segment depression or elevation; T wave inversion suggestive of myocardial ischemia

Elevated levels are associated with CAD

Changes in the electrical activity of the heart are associated with cardiac ischemia, injury, or necrosis

Other Tests: Ambulatory electrocardiographic (ECG) monitoring, exercise echocardiography, stress myocardial perfusion imaging, and cardiac catheterization. Exercise echocardiography is useful in establishing the diagnosis of CAD and allows some determination of risk in patients with angina. Magnetic resonance imaging and computed tomography are able to depict zones of impaired blood supply and to show the coronary anatomy. Electronic beam computed tomography (EBCT) can identify coronary calcification.
