增强型体外反搏治疗慢性心力衰竭的疗效及对心脏超声参数的影响OA

Aim To investigate the efficacy of enhanced external counterpulsation(EECP)in the treatment of chronic heart failure(CHF)and its effects on echocardiographic parameters.Methods One hundred and thirty-four patients with CHF were selected and randomly divided into an observation group(treated with EECP combined with dapagliflozin)and a control group(treated with dapagliflozin).Echocardiographic parameters,serum myocardial enzyme profiles,N-terminal pro-brain natriuretic peptide(NT-proBNP),quality of life(assessed by the Minnesota Living with Heart Failure Questionnaire(MLHFQ)),and 6-minute walking dis-tance(6MWD)were compared between the two groups before and after treatment.Results Compared with the levels before treatment,after treatment,both groups showed increased left ventricular ejection fraction(LVEF)and longer 6MWD,as well as de-creased left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),serum NT-proBNP levels,and MLHFQ scores.Furthermore,the improvement in all these indicators was significantly greater in the observation group than that in the control group(P<0.05).Conclusion The application of EECP can effectively improve clinical efficacy,in-hibit ventricular remodeling,promote cardiac structural remodeling,enhance cardiac function,and improve quality of life in patients with CHF.
