Objective: To investigate the efifcacy of supplemental walking training in patients with coronary artery disease (CAD) combining heart failure (HF) under routine medication.
Methods: A total of 80 patients with CAD combining HF were randomly divided into 2 groups: Exercise group,n=40 including 25 male and 15 female at (61.2 ± 9.8) years of age, the patients received additional six-minute walking exercise training based on routine medication and Control group,n=40 including 26 male and 14 female at (58.1 ± 10.9) years of age, the patients received routine medication. All patients were treated for 3 months. Plasma levels of BNP and general conditions at before and after the treatment were compared between 2 groups.
Results:①After 3 months treatment, both groups had signiifcantly improved LVESD, LVEDD, LVEF, plasma levels of BNP and six-minute walk test (except LVESD and LVEDD in Control group), allP<0.05.②Compared with Control group, Exercise group showed obviously improved LVEF, plasma level of BNP and six-minute walk test, allP<0.05.
Conclusion: Walking training may increase the exercise tolerance, which is beneifcial to recover the cardiac function in patients with CAD combining HF in addition to routine medication .
