| 1 | Effects of exercise training on diastolic and systolic dysfunction in patients with chronic heart failure显示文摘BACKGROUND Chronic heart failure(CHF)is a complex syndrome characterized by a progressive reduction of the left ventricular(LV)contractility,low exercise tolerance,and increased mortality and morbidity.Diastolic dysfunction(DD)of the LV,is a keystone in the pathophysiology of CHF and plays a major role in the progression of most cardiac diseases.Also,it is well estimated that exercise training induces several beneficial effects on patients with CHF.AIM To evaluate the impact of a cardiac rehabilitation program on the DD and LV ejection fraction(EF)in patients with CHF.METHODS Thirty-two stable patients with CHF(age:56±10 years,EF:32%±8%,88%men)participated in an exercise rehabilitation program.They were randomly assigned to aerobic exercise(AER)or combined aerobic and strength training(COM),based on age and peak oxygen uptake,as stratified randomization criteria.Before and after the program,they underwent a symptom-limited maximal cardiopulmonary exercise testing(CPET)and serial echocardiography evaluation to evaluate peak oxygen uptake(VO2peak),peak workload(Wpeak),DD grade,right ventricular systolic pressure(RVSP),and EF.RESULTS The whole cohort improved VO2peak,and Wpeak,as well as DD grade(P<0.05).Overall,9 patients(28.1%)improved DD grade,while 23(71.9%)remained at the same DD grade;this was a significant difference,considering DD grade at baseline(P<0.05).In addition,the whole cohort improved RVSP and EF(P<0.05).Not any between-group differences were observed in the variables assessed(P>0.05).CONCLUSION Exercise rehabilitation improves indices of diastolic and systolic dysfunction.Exercise protocol was not observed to affect outcomes.These results need to be further investigated in larger samples. | Ioannis Chaveles Ourania Papazachou Manal al Shamari Dimitrios Delis Argirios Ntalianis Niki Panagopoulou Serafim Nanas Eleftherios Karatzanos | 2021 | World Journal of Cardiology2021，13，9： | 2 |
