[Prevention of coronary heart disease--"evidence-based medicine" of antilipemic therapy].
A considerable number of large scale clinical trials provide clear evidence that cholesterol lowering is one of the most important risk-reduction strategies for secondary and primary prevention of coronary artery disease. Unlike the older studies with fibrates, the most recent trials of cholesterol-lowering therapies with the 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors have clearly shown that their use can reduce coronary artery disease and total mortality as well as the need for expensive hospitalization and revascularization procedures. Studies such as the Scandinavian Simvastatin Survival Study (4S), the West of Scotland Coronary Prevention Study (WOS), the Cholesterol and Recurrent Events (CARE) trial and most recently the Long-Term Intervention with Pravastatin in Ischaemic Disease (LIPID) as well as numerous other investigations, have established that decreasing elevated levels of low-density lipoprotein (LDL) cholesterol will result in a reduction in risk of coronary artery disease. In addition, HMG-CoA reductase inhibition reduces the risk for cerebral ischemia. Recent data indicate that less than half of patients with coronary artery disease receive cholesterol-lowering therapy, and few meet the LDL-cholesterol goal. Therefore clinicians treating coronary artery disease need to emphasize secondary prevention and recognize the key role of cholesterol-lowering therapy. The challenge for clinicians is to apply the important lessons learned from these clinical trials to an "evidence-based" patient care.
