Signs of coronary atherosclerosis in apparently healthy men with different types of hyperlipoproteinaemia

Abstract

Subjectively healthy males exhibiting markedly elevated fasting serum cholesterol and triglyceride concentrations at a health control examination were analysed. The prevalence of different types of hyperlipoproteinaemia and of ST segment depression during exercise indicating myocardial ischaemia was determined (4.1--4.3 Minnesota code). Encountered types and numbers of subjects with hyperlipoproteinaemia (HLP) were as follows: type IV-94, IIA-31, IIB-14, III-11. The frequency of ST segment depression within each HLP type was as follows: type IIB-65%, IIA--40%,III-35%,IV-30% and in controls with non-elevated serum lipids 10%.
