title: Reduced high density lipoproteins as a risk factor after acute myocardial infarction.
abstract: In a group of normocholesterolemic, non-diabetic middle-aged males surviving an acute myocardial infarction for 4 +/- 2 years (mean +/- SD), we have previously described a low apolipoprotein A-I and a deficient fibrinolytic activity as two major characteristics. In the present study we have followed morbidity and mortality risk factors for five years in these males. Mortality was 40% in a hypertensive group and 16% in a normotensive group. In the normotensive group mortality was related to reinfarction. Furthermore, patients with a poor prognosis in the normotensive group had lower high density lipoprotein (HDL) cholesterol and lower apolipoprotein A-I concentration in plasma than patients with a good prognosis. Unexpectedly, in the hypertensive group death was related to a low (p less than 0.05) cortisol concentration in urine. It is concluded that a low HDL level may be a bad prognostic sign in males who have sustained an acute myocardial infarction and show no evidence of other risk factors, such as diabetes, hypercholesterolemia or hypertension.
