[Left ventricular mass of the myocardium and its contractile capacity in hypertensive patients in the postinfarct period]. / Massa miokarda levogo zheludochka i ego sokratitel'naia sposobnost' u bol'nykh gipertonicheskoi bolezn'iu v postinfarktnom periode.

ABSTRACT

Seventy patients with hypertonic disease (HD) in the IInd stage were examined echocardiographically 30 days and 6 months after macrofocal myocardial infarction with the view to study contractility of myocardium of the left ventricle depending on its mass. Increase of the left ventricle mass (LVM) in patients with HD after infarction was established to be associated with rise of myocardial contractility. Fall of the LVM occurs at the account of thinning of ventricular wall without changes in volumic parameters of the left ventricle.
