Risk factors for the development of premature cardiovascular disease.
The elucidation of the major risk factors for the development of premature atherosclerosis including plasma cholesterol, hypertension, and smoking has permitted the institution of specific therapy to reduce the risk of vascular disease. The further elucidation of LDL and HDL as positive and negative risk factors, respectively, has provided additional insights into the role of lipoproteins in cholesterol transport and atherosclerosis. Analysis of plasma apolipoproteins suggests that they may be even more effective than lipoproteins as predictors of premature vascular disease. The results of the Lipid Research Clinics Coronary Primary Prevention Trial clearly established the effectiveness of decreasing coronary risk by the reduction of LDL cholesterol in hyperlipidemic subjects. Aggressive diet and drug treatment of patients with elevated plasma levels of LDL would be anticipated to have a major impact on the development and/or progression of premature vascular disease. The implications of reduced levels of HDL on clinical practice is less certain. At present there is no evidence that interventions that change HDL levels will influence the development of vascular disease. In addition, the role of triglycerides and triglyceride-rich lipoproteins as potential risk factors for the development of premature atherosclerosis has not been firmly established. Additional epidemiological studies as well as basic research will undoubtedly provide the answers to these important unresolved questions.
