[Characteristics and prevalence of various types of left ventricular myocardial dysfunction in patients with chronic cardiac failure].
Prevalence of systolic and diastolic myocardial dysfunctions of the left ventricle (SDLV, DDLV) was studied in 223 patients with chronic cardiac failure (CCF) arising in the presence of arterial hypertension (AH), coronary heart disease (CHD) and their combination. The diagnosis was made in outpatient diagnostic center and included patients free of distinct clinical symptoms of CHD. DDLV was rather prevalent in a functional class (FC) I of CCF, in AH patients with SDLV FC III and CHD patients. Mean duration of cardiovascular diseases (CVD) before CCF onset with various types of left ventricular dysfunction was determined. Echocardiographic, including Dopplerographic, criteria of SDLV and DDLV were studied and their significance depending on FC and etiology of CCF was ascertained. The study elicited regularities of CCF formation in patients with various cardiovascular diseases, impact of the latter on myocardial dysfunction, echocardiographic features of CCF by systolic and diastolic type.
