A clinical and metabolic study of 61 patients with myoocardial infarct before the age of 40 yr showed a high frequency of familial involvement, particularly in subjects with type IIA and IIB hyperbetalipoproteinaemia. Excess weight and arterial hypertension were rare, while premonitory angina was absent in 59%. Four subjects were diabetic. Oral glucose tolerance was normal in 14 and of diabetic type in 26 of 40 patients examined; the insulin response pointed to insulin-resistance. Dyslipidaemia was noted in 45%, including type IIA and IIB hyperbetalipoproteinaemia in 27%. Distribution of the frequency of infarct in function of cholesterolaemia classes gave a bimodal curve indicative of distinct normo- and hypercholesterolaemic groups within the series.

Abstract

A clinical and metabolic study of 61 patients with myoocardial infarct before the age of 40 yr showed a high frequency of familial involvement, particularly in subjects with type IIA and IIB hyperbetalipoproteinaemia. Excess weight and arterial hypertension were rare, while premonitory angina was absent in 59%. Four subjects were diabetic. Oral glucose tolerance was normal in 14 and of diabetic type in 26 of 40 patients examined; the insulin response pointed to insulin-resistance. Dyslipidaemia was noted in 45%, including type IIA and IIB hyperbetalipoproteinaemia in 27%. Distribution of the frequency of infarct in function of cholesterolaemia classes gave a bimodal curve indicative of distinct normo- and hypercholesterolaemic groups within the series. Reduced glucose tolerance was more frequent in patients with low blood cholesterol. This suggests that reduced tolerance and high blood cholesterol are independent risk factors in coronary disease. No relation between the clinical and metabolic data could be ascertained.
