Abstract Objective: To evaluate left ventricular systolic and diastolic function before and after treatment by acoustic quantification(AQ). Methods: Thirty-four normal subjects were selected as control group, 34 consecutive patients with a clinical diagnosis of congestive heart failure were studied by echocardiography. Left ventricle end diastolic volume(EDV), end systolic volume(ESV), ejection fraction(EF), peak ejection rate(PER), peak rapid filling rate(PRFR) and peak atrium filling rate(PAFR) were also measured, PRFR/PAFR were calculated. Results: Compared with healthy controls, EDV, ESV, PRFR and PAFR had significantly increased?穴P<0.001, P<0.001, P<0.001 and P<0.05 respectively), EF and PER significantly decreased(P<0.001 and P<0.05 respectively), PRFR/PAFR had no significant differences. ESV, EDV and PAFR had significantly decreased(P<0.001), EF and PER significantly increased(P<0.001), PRFR and PRFR/PAFR had no significant differences after treatment(P>0.05). Conclusions: AQ is helpful to evaluate left ventricular systolic function, while evaluating left ventricular diastolic function of heart failure patients in late phase, AQ is limited.
