LEFT VENTRICLE DIASTOLE MALFUNCTION SEVERITY LEVEL DIAGNOSIS OF PATIENTS WITH CHRONIC CARDIAC FAILURE

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to cardiology. The echocardiography is used to value such parameters as E/A, DT, IVRT (TMD) and S/D spectra at rest and during load Doppler's testing - the degree of decline in E / A at a height of the Valsalva test (E/A Vals), diastolic left ventricle (LV) reserve at an altitude of isometric (DR isom) and cold (DR cold) loads. It is also used to determine the ejection fraction value of the LV and end diastolic volume index of the left and right ventricles, the Myocardial mass and if they meet the certain rules, a certain differential diagnostic phage (DDP) stage is set. This method allows to increase the accuracy of identifying patients with initial (stage I of DDP), and frank diastole malfunctions, also clearly distinguishing patients with a normal TMD spectrum and patients with pseudo-normalisation (Stage II of DDP), and determining the degree of LV malfunction of the patients with the chronic cardiac failure.;EFFECT: diagnosis accuracy increasing of the patients with ICP.;1 dwg, 5 tbl, 4 ex
