title: [Echocardiographic study of the contractile function of the affected and intact areas in the acute period of macrofocal myocardial infarct].
abstract: Daily echocardiographic examination was conducted of 31 patients in the acute period of macrofocal myocardial infarction with anteroseptal and posterior localization of left ventricular affection. The hemodynamic indices were determined and regional contractility both in the zone of infarction and in areas opposite the infarction was studied. The authors point to the possibility of partial restoration of the contractility of the wall in the zone of disturbed circulation beginning with the third day of the disease. In the absence of signs of partial restoration of regional contractility in the zone of affection the prognosis is much worse. It is concluded that the hemodynamic disorders in the acute period of macrofocal myocardial infarction are determined by the size of the affected area, the possibility of partial restoration of contractility in the zone of impaired circulation and by the compensatory reserves of areas remote from the infarction.
