不同训练时间太极拳运动康复方案对慢性心力衰竭病人心功能的影响

The Influence of Tai Chi Rehabilitation Program with Different Training Time on Cardiac Function of Patients with Chronic Heart Failure

目的评价不同训练时间太极拳运动康复方案对慢性心力衰竭病人心功能的影响。方法纳入符合条件的慢性心力衰竭病人120例,采用简单随机、对照方法,分为对照组、短时间组(太极拳S组)、长时间组(太极拳L组),各40例。所有病人均按照指南指导标准药物治疗和常规康复建议,在此基础上分别给予不同太极拳运动方案进行研究。所有病人每周至少进行5次康复训练,疗程24周。于12周及24周检测3组脑钠肽(BNP)、左室射血分数(LVEF)、6min步行试验(6MWT)。结果治疗12周后,太极拳S组和太极拳L组6MWT长于与对照组,差异有统计学意义(P<0.05);太极拳S组和太极拳L组LVEF高于对照组,差异有统计学意义(P<0.05);太极拳S组和太极拳L组BNP水平低于对照组,差异有统计学意义(P<0.05)。治疗24周后,太极拳L组6MWT长于太极拳S组,太极拳L组LVEF高于太极拳S组,BNP水平低于太极拳S组,差异有统计学意义(P<0.05)。结论太极拳运动康复方案可较好地改善慢性心力衰竭病人的心功能状态和运动耐量,且慢性心力衰竭病人采用60min太极拳运动方案并坚持锻炼,在改善运动耐量方面获益更大。

Objective To investigate the clinical influence of Tai Chi rehabilitation program with different training time on cardiac function of patients with chronic heart failure.Methods One hundred and twenty patients with chronic heart failure were divided into the control group,30 minutes Tai Chi training group (S group),and 60 minutes Tai Chi training group (L group),40 cases in each group.All patients were given different Tai Chi rehabilitation program on the basis of pharmacologic therapy,dietary,and exercise counseling.Tai Chi rehabilitation program consisted of a 30 to 60 minutes class held 5 times weekly during 24 weeks.Brain natriuretic peptide(BNP),left ventricular ejection fraction(LVEF),and 6 minute walk test(6MWT) were compared between two groups.Results After 12 weeks,6MWT and LVEF were increased in S group and L group,which were better than those in the control group ( P <0.05).BNP was decreased in S group and L group,which were better than that in the control group( P <0.05).After 24 weeks,6MWT and LVEF were increased in L group than those in S group( P <0.05).BNP was decreased in L group than that in S group( P <0.05).Conclusion Tai Chi rehabilitation program can improve the cardiac function and exercise tolerance of patients with chronic heart failure,the longer to keep practicing 60 minutes Tai Chi rehabilitation program everyday and the more benefit in improving exercise tolerance.
