Eff ect of modifi ed lip-constricted abdominal breathing training on exercise endurance in patients with chronic heart failure

目的 探讨改良缩唇腹式呼吸训练应用于慢性心力衰竭患者对运动耐力的影响。方法选择2020年9月—2021年8月江南大学附属医院心内科收治的慢性心力衰竭患者104例,按组间基本特征匹配原则将患者分为对照组51例和观察组53例。对照组实施常规护理干预;观察组实施改良缩唇腹式呼吸训练。比较两组干预前后6 min步行距离(6MWD)、肺功能及生活质量。结果 干预3个月后,观察组6MWD长于对照组;FEV_(1)、FVC、FEV_(1)/FVC、MVV水平均高于对照组;躯体领域、情绪领域、其他领域、生活质量总分均低于对照组;上述指标组间比较差异有统计学意义(P<0.05)。结论 改良缩唇腹式呼吸训练应用于慢性心力衰竭患者中可提高运动耐力,改善生活质量。

Objective To investigate the effect of modified lip-constricted abdominal breathing training on exercise endurance in patients with chronic heart failure. Methods 104 patients with chronic heart failure admitted in the Department of Cardiology, A ffi liated Hospital of Jiangnan University from September 2020 to August 2021 were selected and divided into a control group(n=51) and an observation group(n=53) according to the principle of basic feature matching. The control group carried out routine nursing intervention;The observation group received improved lip-contraction abdominal breathing training. 6 mins Walking distance(6MWD), lung function and quality of life were compared between the two groups before and after intervention. Results After 3 months of intervention, 6MWD of the observation group was longer than the control group. The levels of FEV_(1), FVC, FEV_(1)/FVC and MVV were higher than the control group. The total score of body domain,emotion domain, other domain and quality of life was lower than the control group. There were statistically significant dif ferences in the above indexes among groups(P<0.05). Conclusion Improved lip-constricted abdominal breathing training could improve exercise endurance and quality of life in patients with chronic heart failure.
