Role of the right ventricle in compensating for cardiac activity in myocardial infarct

Changes in the phase structure of the systole and diastole of both ventricles of the heart with relation to the presence or absence of cardiac failure were studied in 68 patients with myocardial infarction. Four variants of such changes were defined. It was established that the right ventricle could...

Summary:Changes in the phase structure of the systole and diastole of both ventricles of the heart with relation to the presence or absence of cardiac failure were studied in 68 patients with myocardial infarction. Four variants of such changes were defined. It was established that the right ventricle could be a factor of the compensation of cardiac activity in myocardial infarction. Change in the phase structure could be of prognostic value with regard to the development of cardiac failure. The appearance of the right ventricular high diastolic pressure syndrome against a background of a decrease in left ventricular contractility was shown to be an early sign of congestion in the pulmonary circulation and a prognostic criterion of the appearance of clinically marked left ventricular insufficiency in the nearest future requiring adequate therapy. Marked asynchronism in ventricular activity contributes to the development of cardiac failure in myocardial infarction.
