Abstract

Abstract: In order to investigate the echocardiographic evaluation of left ventricular diastolic dysfunction and its reliability in patients with heart failure, this study selected 98 patients with heart failure as the test group, and 98 healthy people as the control group. Both groups underwent echocardiography and the results were compared. The results showed that the left atrial dimension (LAD), interventricular septal thickness (IVST), leftventricular end-diastolic diameter (LVDd), left ventricular end-systolic dimension (LVDs) and left ventricular posterior wall thickness (LVPWT) in the test group were all higher than those in the control group (P<0.05). Compared with control group, the deceleration time (DT) of test group were lower,while the mitral valve diastolic early E peak speed/diastolic late A peak speed(E/A), early diastolic velocity of mitral annulus from septal (Esep), early diastolic velocity of mitral annulus 897 from lateral (Elat), the mitral valve diastolic early E peak velocities/mitral valve diastolic early peak velocities(E/Ea) were higher (P<0.05). The LVDd, left ventricular ejection fractions (LVEF) and E/A of the patients with E/Ea ≥ 15 in the test group were higher than those with E/Ea<15, and DT of the patients with E/Ea ≥ 15 was lower than those with E/Ea<15 (P<0.05). In conclusion, the left ventricular diastolic function and left ventricular diastolic function can be accurately evaluated by cardiac ultrasound.
