[Regional and general contractile function of the myocardium following myocardial infarct].
A total of 93 patients with myocardial infarction were investigated 3-4 mos. after the beginning of disease by the method of radionuclide ventriculography. Total and regional ejection fractions (for 7 zones), left ventricular functional volumes (end-systolic, end-diastolic and stroke volumes), rates of contraction and expulsion were determined. A certain level of left ventricular pump function in patients after myocardial infarction was determined by the ratio of the number of hypokinetic segments and the expression of a decrease in their contractility and normo- and hyperkinetic segments which are the main compensatory factor. Variations in the structure of formation of the total ejection fraction with relation to a site of myocardial infarction were revealed. Compensatory significance of hyperkinetic zones is decreased with a growing degree of expression of contraction asynergia.
