摘要
Abstract
Objective To explore value of functional cardiac reserve indicators in evaluation chronic heart failure(CHF).Methods 136 patients with CHF served as heart failure group and 46 healthy people as control group.Color Doppler ultrasound echocardio-graphy was used and left ventricular ejection fraction(LVEF) were calculated.6 minute walk test(6MWT) was performed, and cardiac reserve non-invasive monitoring system was employed to detect ratios of diastolic phase duration to systolic phase duration(D/ S).The correlations between LVEF, 6MWT, D/S value and cardiac functional status were evaluated, respectively.Results 6MWD, D/S value and LVEF of patients in heart failure group were obviously lower than those in control group(P<0.05).According to bivariate Pearson correlation coefficient analysis, D/S value and 6WMD showed negative correlation with New York heart association(NYHA) cardiac functional grading(r= -0.659, P<0.01;r= - 0.561,P<0.01).LVEF and NYHA cardiac functional grading were positively correlated (r=0.203, P<0.05).Conclusion D/S value reflects well on status of cardiac function of patients with CHF, and can be served as a new and effective indicator in evaluation of cardiac function.关键词
