The aim of the study was to determine the peculiarities of left ventricular systolic and diastolic function in patients with ischemic cardiomyopathy. In our study have been involved 20 practicall healthy and 62 affected with aschemic cardiomyopathy. Has been performed overall Echocardiographic study of characteristics of structuro-functional index at Ischemic Cardiomyopathy of different severity. The patients were randomized in to 3 groups: patients with moderately expressed reduction of left ventricle ejection fraction (EF>40%), patents with systolic dysfunction of average severity (EF 30-40%), and expressed reduction ejection fraction of LV (EF<30%). Have been established the following oriental Echocardiographic criteria of ischemic cardiomyopathy: end diastolic size of LV – more than 52 mm, end diastolic volume of LV – more than 133 ml, index of LV myocard mass – more than 140 g/m², EF – less than 50%, shortening fraction – less than 23%, index of local contractility – more than 1,3. In patients with Heart ischemic disease at prevalence of at least three components, Echo-index of formation in considered as of high probability.
