Ischemic cardiomyopathy: echocardiographyc diagnostic markers.
Purpose of the pilot study was to reveal structural and functional features of heart failure at different severity levels of ischemic cardiomyopathy (ICMP). 62 patients affected with ICMP have been involved in the study: 9 men (15%) and 51 (85%) women (average age 62,63+/-13,11). The control group was composed of 20 healthy persons. Heart infarction (HI) was recorded in all affected patients' anamnesis. Patients affected with chronic aneurism of left ventricular (LV) were not covered in the study. Chronic heart insufficiency of functional group II-III (NYHA) was observed in all patients. Depending on the LV systolic dysfunction, the patients were randomized into three groups: I group - patients with expressed reduction of the left ventricle ejection fraction (EF<30%), II group - patients with systolic dysfunction of average severity (EF 30-40%), III group - patients with moderately expressed reduction ejection fraction of LV (EF<40-50%). The following echocardiographic criteria of ischemic cardiomyopathy have been established: final diastolic size of LV - more than 52 mm, final diastolic volume of LV - more than 133 ml, index of LV myocardial mass - more than 140 g/m(2), EF - less than 50%, fractional shortening (FS)- less than 23%, index of local contractility - more than 1,3. In Patients with ischemic disease at prevalence of at least three components, Echo-index of formation in considered as of high probability.
