目的：探讨6 min步行运动训练对射血分数保留的心力衰竭患者运动耐力的影响。方法：采用随机法将50例射血分数保留(LVEF≥50%)的心力衰竭患者分为训练组及对照组，每组25例。两组患者均给予常规药物治疗，训练组在上述治疗基础上每日辅以6 min步行运动训练。6个月后观察两组患者治疗前、后6 min步行距离变化情况。结果：经6个月治疗后，训练组6 min步行距离提高幅度显著优于对照组(P<0.05)。结论：6 min步行运动训练能显著改善射血分数保留心力衰竭患者的运动耐力，有益于提高生活质量。

Objective:To investigate the effects of 6-minutes of walking exercise(6-MWE) on the exercise tolerance of heart failure patients with preserved ejection fraction(HFpEF).Method:Fifty heart failure patients with preserved ejection fraction(LVEF≥50%) were randomly divided into an exercise training group and a control group with 25 cases in each.Each group was treated with routine drug.The exercise training group was treated with the same drugs plus 6-MWE.Before and after the six-month period of treatment,their 6-minute walk distance(6-MWD) was measured.Result:The 6-MWD of the experimental group improved significantly more than control group after 6 months(P<0.05).Conclusion:6-MWE can significantly improve the exercise tolerance of HFpEFs,and improve their quality of life.
