Statins, platelet aggregation and coronary heart disease.

It is becoming increasingly recognized that the beneficial effects of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-Co-A) reductase inhibitors (statins) on reducing clinically important cardiovascular events (myocardial infarction and stroke) are not only attributable to their hypocholesterolemic effect but also to non-lipid mechanisms of action. The nonlipid factors may include the stabilization of arterial plaques, endothelial normalization, anti-inflammatory effects and inhibition of platelet thrombus formation. The inhibition of platelet thrombus formation has not been adequately studied in man and the results are often contradictory.
