Introduction

The cardiovascular system consists of the heart and the blood vessels that distribute blood to the entire body. The system is designed to provide oxygenated blood to tissues in order to maintain function. Much of this exchange occurs at the level of the capillaries and arterioles where surface contact between the blood cells carrying oxygen and the tissues is greatest. While the system is relatively simple in design, it is essential to the normal physiology of the body and is maintained at a level of activity that can supply energy under normal circumstances as well as under situations of stress where greater activity is required. Because of its importance to normal physiology, it should be obvious that abnormal functioning of the cardiovascular system can have an enormous deleterious impact on the homeostatic function. Disorders of the cardiovascular system are a primary contributor to the global morbidity and mortality that continues to increase in prevalence in spite of remarkable advances in the methods used to manage the disease. In fact, cardiovascular disease (CVD) has annually been the leading cause of mortality for over a century. For these reasons alone, the diseases that form the constellation of CVD are the focus of intensive research efforts by the biomedical research community. Considerable attention has been focused both on the underlying molecular basis of these diseases and the agents that can be used for the therapeutic management of CVD.
