title: [Role of hyperlipidemia in disorders of myocardial function in men with or without angina pectoris and post-infarction cardiosclerosis].
abstract: The paper is concerned with evaluation of myocardial function in men under 50 without the clinical manifestations of coronary heart disease (CHD), in patients with angina pectoris and postinfarction cardiosclerosis. The examinees were divided into groups with and without hyperlipidemia (HLP). The cholesterol level not less than 300 mg/100 ml (7.76 mmol/l) and the triglyceride level not less than 200 mg/100 ml (2.25 mmol/l) was regarded as hyperlipidemic. To judge myocardial function, use was made of the criterion of exercise tolerance on a treadmill and of polycardiography (PCG) and apical cardiography (ACG). It was established that in groups with HLP, the exercise tolerance was lower than in analogous clinical groups without HLP. PCG and ACG were also helpful in a more frequent detection of cardiodynamic disorders in HLP groups. The exercise test has shown that in HLP, the ischemic responses in CHD patients occur more readily and more frequently. Possible mechanisms of an adverse effect of HLP are discussed.
