Echocardiographic evaluation of left ventricular function in ischemic heart disease (IHD)

A comparison was performed between the echocardiographic (EchoC) indices for the pump and contraction function of left ventricle and the stage of left-ventricle insufficiency, determined according to clinical criteria of 82 patients with ischemic heart disease (IHD)--old myocardial infarction and (or stable angina pectoris without left-ventricle infarction and for stable angina pectoris without left-ventricle aneurysm. With IHD, regardless of the considerable asynergy of left ventricle, some of the functional EchoC-indices were established to preserve their diagnostic values and definitely to differentiate the majority of the cases with, from those without, cardiac insufficiency, objectivizing the determination of initial left-ventricle insufficiency. The most significant diagnostic value of EchoC-assessment of left-ventricle function in IHD has the following complex of EchoC-indices: diastolic extent, left ventricle index resp, expulsion fraction (EF), shortening fraction (FS), average velocity of circumferential fibres (VCF), distance between point E of mitral echogram and interventricular septum (S-E distance), telediastolic interval A-C of mitral echogram and extent, index of left auricle, resp.
