[Myocardial infarct in young persons].

A study of 106 patients with myocardial infarction, aged under 40 demonstrated a predominance of males (90.5%) with prevailing marco-focal and transmural myocardial infarctions. In 88 patients (83%) risk-factors of ischaemic heart disease were found: arterial hypertension, hypercholesterolemia, heavy smoking, excessive weight, sedentary life. The severity of the course of myocardial infarction is directly related to the presence of risk factors in the patient. Studies of the content of immunoglobulins in 15 patients revealed an immunologic hyperrectivity in young patients with myocardial infarction when they developed complications. Autopsy data of 5 mortality cases demonstrated atherosclerotic lesions of the coronary arteries in all of them.
