HIGH DENSITY LIPOPROTEIN CHOLESTEROL AND INCIDENCE OF CORONARY HEART DISEASE THE ISRAELI ISCHEMIC HEART DISEASE STUDY

TLDR

Univariate and multivariate analyses were employed to examine the relationship between high‑density lipoprotein cholesterol and coronary heart disease incidence. In a five‑year prospective cohort of 6,500 Israeli men, higher HDL cholesterol was inversely associated with myocardial infarction, angina, sudden death, and MI mortality—particularly in those over 50—an association that persisted after adjusting for age, other lipids, smoking, blood pressure, weight, and diabetes, indicating HDL as an independent protective factor for CHD.

Abstract

Using univariate and multivariate analyses, the association between high density lipoprotein (HDL) cholesterol and coronary heart disease (CHD) incidence was investigated. Over 150 cases of myocardial infarction (MI) occurred among 6500 Israeli adult males in a five-year prospective study. At age 50 years and over, there is a significant inverse association between MI incidence and HDL cholesterol. This relationship persists when controlling for risk factors such as age, other cholesterol components, smoking, blood pressure, weight, and diabetes mellitus. Unlike hypercholesterolemia and smoking, the relative risk with HDL cholesterol increases with age above 50. Similar patterns of association occur between HDL cholesterol and angina pectoris incidence, sudden unexpected death and deaths from MI. It is suggested that HDL cholesterol Is an independent risk factor for CHD, especially in males over 50, and the implication of this study is that increased HDL cholesterol might play a protective role in the pathogenesis of CHD.
