[Type of behavior pattern and risk factors in young men after myocardial infarction]

The studies involved 102 male patients, aged between 23 and 40 years, with a history of one myocardial infarction. Behaviour pattern was determined with The Jenkins Activity Survey questionnaire. Total serum cholesterol, triglycerides, glucose, and uric acid concentrations were assayed, both diastolic and systolic blood pressures were measured, all patients were weighed, and reported the number of smoked cigarettes. A mean number of risk factors per patient was calculated as well as their incidence in various behaviour patterns. It was found behaviour pattern A predominates in young male patients with a history of myocardial infarction. However, serum total cholesterol, triglycerides, and uric acid levels were lower in this group in comparison with those representing behaviour patterns B and X. The authors suggest that behaviour pattern A may be an independent risk factor for myocardial infarction in young subjects. Further studies are, therefore, needed within the programs of circulatory diseases prevention.
