title: [The effect of lowering cholesterol on mortality].
abstract: There is little doubt about the validity of the lipid hypothesis as a pathogenetic theory for atherosclerosis. However, this theory does not allow the conclusion that cholesterol-lowering treatment is necessarily beneficial in practice. As a consequence of the probabilistic nature of risk factors, the classification of plasma cholesterol levels into "normal" and "pathological" can be misleading in clinical practice. The potential benefit of cholesterol-lowering treatment is a direct function of the overall coronary risk, more or less independently of plasma cholesterol. Therefore, plasma cholesterol is of clinical significance only in patients with established CHD and a high overall risk of infarction. Total mortality has been prospectively included as one end-point in addition to infarct mortality in the many intervention studies on cholesterol-lowering. Meta-analyses of these studies show a non-significant decrease in infarct mortality through cholesterol-lowering drug treatment, with a concomitant, highly significant increase in non-infarct mortality. Lowering cholesterol in asymptomatic persons and in coronary patients with a relatively low risk of infarction results in a significant increase in total mortality. Only in a very small group of coronary patients with a very high risk of myocardial infarction, due to the presence of several additional risk factors, may cholesterol-lowering treatment be beneficial.
