Implications of the atorvastatin versus revascularization treatment (AVERT) study for the clinician.

The underlying disorder in the vast majority of cases of cardiovascular disease is atherosclerosis, for which low-density lipoprotein cholesterol is recognized as a major risk factor. Data from epidemiologic studies have suggested that lower cholesterol levels are associated with a lower overall risk of morbidity and mortality due to coronary heart disease. Numerous clinical trials with lipid-lowering agents support these epidemiologic data. Of these, studies with the HMG-CoA (3-hydroxy 3-methylglutaryl coenzyme A) reductase inhibitors, or statins, have shown the greatest lipid-lowering effects. Data from recent trials such as the Atorvastatin Versus Revascularization Treatment contribute to a growing body of evidence that suggests that aggressive reduction of cholesterol can yield additional clinical benefits above and beyond that observed with less robust treatment regimens. Aggressive cholesterol-lowering strategies have the potential therefore to have a significant impact on levels of atherosclerotic disease throughout the westernized world. Such effects argue in favor of renaming the entire class of drugs as anti- atherosclerotic rather than lipid-lowering agents.
