[The role of intracardiac hemodynamic parameters in prognosis of cardiac failure in myocardial infarction patients].

Two-dimensional echocardiography was used to study intracardiac hemodynamics (end systolic, end diastolic volumes and left atrial ejection fraction; end systolic, end diastolic volumes and left ventricular fraction; mean pressure in the pulmonary artery; myocardial mass of the left ventricle) in 49 patients 2, 10 and 30 days after onset of macrofocal myocardial infarction (MI). It was found that patients with and without cardiac failure after one year of the diseases significantly differed by volume and function of the left ventricle and atrium registered since MI day 2. Probability of cardiac failure in the postinfarction period may be estimated since the disease day 2 by an increase in the end-systolic and end-diastolic volumes and left ventricular ejection fraction. A restrictive type of left ventricular diastolic dysfunction is one of the early prognostic criteria of cardiac failure in postinfarction period.
