[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.

[Myocardial contraction in ischemic heart disease].

The indices of contractility of the left ventricular myocardium were studied by means of ventriculography and catheterization in 84 patients with ischemic heart disease according to the extent of damage to the coronary arteries and the course of the disease. Changes in the coronary arteries were encountered twice as frequently among patients with postinfarction cardiosclerosis as among patients with angina pectoris and no history of infarction. The main cause of disorders of myocardial contractility in patients with ischemic heart disease is post-infarction cardiosclerosis (56% of cases). Signs of impaired functional capacity of the left ventricle appeared in segmental asynergy involving 20 to 25% of its circumference. Changes in the indices of contractility were revealed in 13% of patients with angina pectoris.
