[Interconnection between segmentary contractility and dysfunction of left ventricle in patients with post-infarct cardiosclerosis ].

Intracardiac hemodynamics and segmental contractility were studied in 227 patients with postinfarction cardiosclerosis without ischemic cardiomyopathy and chronic aneurysm. Decreased ejection fraction (EF < 50%) was noted in 41 (18.1%) patients. Systolic dysfunction was frequently observed in patients with the local contractility index (LCI) exceeding 1.25. The highest degree of the left ventricular end-diastolic diameter (EDD) and end-diastolic volume (EDV) was evidenced by the anteroseptal localization of the postinfarction scar. The diastolic dysfunction of the left ventricle was mostly observed in patients with LCI less than 1.25 and posterolateral localization of scar.
