Tai Chi For The Cardiopulmonary Function And Efficacy Of Patients With Chronic Heart Failure:A Systematic Review And Meta-analysis

Objective:To systematically evaluate the cardiopulmonary function and efficacy of Tai Chi for patients with chronic heart failure,and to provide evidence-based medicine evidence for clinical practice.Methods:Randomized controlled trials were retrieved from PubMed,Cochrane Library,EMbase,CNKI,Wanfang Journal Database,and VIP Chinese Journal Service Platform before June 2022.The Chinese search terms included:“Tai Chi,Tai Chi,traditional exercise therapy,skill,chronic heart failure,chronic heart failure,randomized controlled trial,random”;the English search terms included:“health Qigong,fitness skill,Taijiquan,Tai chi,Taichi qigong,Qigong,Chronic heart failure,randomized controlled trial,RCT”.Meta-analysis was performed using Rev Man 5.4 software.Results:Twenty studies involving 1711 patients were included,of which821 were in the observation group and 781 were in the control group.The trial group was better than the control group in improving cardiac function efficacy[RR=1.12,95%CI（1.01,1.25）,P=0.04],6min walk test[MD=37.61,95%CI（2.50,7.72）,P=0.04],MLHFQ score[MD=-8.60,95%CI（-10.14,-7.06）,P<0.00001],LVEF[MD=4.18,95%CI（1.13,7.23）,P=0.007],LVEDd[MD=-3.94,95%CI（-6.58,-1.30）,P=0.003],VO₂peak[SMD=0.70,95%CI（0.48,0.91）,P<0.00001],BNP[MD=-42.04,95%CI（-75.02,-9.05）,P=0.01],and the differences were statistically significant.Conclusion:Tai Chi combined with conventional drug therapy can improve the cardiac function efficacy of CHF patients,reduce serum BNP,increase 6min walking distance,improve VO₂peak,LVEDd,LVEF and MLHFQ scores,and find no significant adverse effects,with high safety.
