[Homocysteinemia as a risk factor for early myocardial infarct--a case-control study].

Purpose: To investigate if hyper-homocysteinemia represents an independent risk factor of early coronary disease.

Methods: We studied a group of patients under 45 years old, that suffered a myocardial infarction from 3 months and 1 year before the study. The patients were matched with a group of normal controls of a check-up program, in terms of age, sex, smoking habits, presence of hypertension, obesity, (Quetelet Index), presence of diabetes, basal glycemia, total cholesterol, LDL and HDL cholesterol.
