[Left ventricular function in patients with dilated cardiomyopathy].
Functional state of left ventricle was studied in 43 patients with dilated cardiomyopathy. All the patients showed pronouncedly reduced total ejection, stroke volume and cardiac index, increased final diastolic and final systolic volumes, decreased ejection rate indices. Analysis of regional contractility of left ventricle allowed to detect significant fall of ejection fraction in 96.3% of segments. Diastolic dysfunction was characterized by disorders of isovolumetric relaxation, changes in hemodynamical structure and contribution of atrial systole to ventricular filling, decrease of volumetric compliance of left ventricle. The data obtained give a reason to consider that appropriate therapy of dilated cardiomyopathy should be carried out with taking into account both systolic and diastolic left ventricle dysfunction.
