title: Effect of Controlling Hypercholesterolemia on Myocardial Ischemia.
abstract: Hypercholesterolemia causes myocardial ischemia, even in the absence of obstructive coronary artery lesions. Reductions in cholesterol are associated with improved clinical outcomes that may reflect reversal of endothelial dysfunction, lesion regression, or both. This review explores experimental and clinical evidence that supports these observations. These include: 1) mechanisms by which hypercholesterolemia (and other risk factors for coronary artery disease) causes endothelial dysfunction; 2) the role that hypercholesterolemia and endothelial dysfunction play in atherogenesis, lesion complications, and clinical ischemic syndromes; and 3) compelling data that illustrate the benefits of cholesterol control. The latter include transformation of the plaque lipid composition to a more favorable profile, improved blood pressure control, normalization of exercise test results, improved exercise tolerance, and reversal or prevention of myocardial perfusion abnormalities. Collectively, these data support the notion that control of cholesterol is important to both the prevention and treatment of cardiac disease.) (c)2001 CHF, Inc.
