[Evaluation of myocardial contractile function in chronic postinfarct cardiac aneurysm].

The ventriculograms of patients with chronic postinfarction aneurysm of the heart were studied with the use of separate analysis of the contraction indices of the functioning and non-functioning parts of the left ventricular myocardium. Relatively high indices of the ejection fraction of the functioning part of the myocardium with low indices of the total ejection fraction were noted. A correlative dependence was found between the total ejection fraction and the ratio of the volumes of the nonfunctioning part of the myocardium during systole and diastole to the total volume of the left ventricle during the same phases, which is evidence that these indices are important in appraising myocardial contractile function in aneurysm of the heart.
