Results of recent large cholesterol - Lowering trials and implications for clinical management

Three recent large clinical trials-the West of Scotland Coronary Prevention Study, the Scandinavian Simvastatin Survival Study, and the Cholesterol and Recurrent Events Trial-have all confirmed that cholesterol lowering with HMG-CoA reductase inhibitors is safe and effective therapy to prevent an initial recurrent coronary event in patients at high risk for coronary heart disease. However, a number of questions related to the treatment of lipid disorders and risk reduction for coronary heart disease remain, including the cholesterol concentration at which treatment would best be initiated, the optimal cholesterol reduction or goal to be attained, and the mechanisms by which HMG-CoA reductase inhibitors reduce the risk for clinical events.
