Abstract

OBJECTIVE

To investigate how group-based exercise affects the levels of physical activity, physical fitness and health- related quality of life (HRQoL) in patients with chronic heart failure and comorbidities.

DESIGN

Randomized controlled trial.

PATIENTS

A total of 48 patients (10 women, 38 men), mean age 71 years (standard deviation 8 years), ejection fraction 27% (standard deviation 10%), and New York Heart Association functional class II-III.

METHODS

A bicycle test, 6-min walk test (6MWT) and muscle endurance tests were performed. Physical activity was assessed with a pedometer and the International Physical Activity Questionnaire (IPAQ), HRQoL was evaluated with the Short Form-36 (SF-36). Patients were randomized to control or intervention groups. Intervention consisted of an individually designed group-based exercise programme twice a week, for a period of 3 months. Subjects in the control group were asked to continue with their usual lives.

RESULTS

A total of 42 patients completed the study, and 6 dropped-out. Steps/day did not increase significantly after intervention (p = 0.351), but IPAQ score did (p = 0.008). Exercise tolerance (p = 0.001), 6MWT (p = 0.014), shoulder abduction (p = 0.028), heel lift (p < 0.0001) and HRQoL (p = 0.018) improved significantly in the intervention group compared with the control group.

CONCLUSION

Group-based exercise did not improve the level of physical activity in patients with chronic heart failure and comorbidity; however, physical fitness and HRQoL were significantly improved.

摘要

目的

研究小组运动对合并症的慢性心力衰竭患者的身体活动水平、身体适应性和健康相关生活质量（HRQoL）的影响。

设计

随机对照试验。

患者

共 48 例患者（10 名女性，38 名男性），平均年龄 71 岁（标准差 8 岁），射血分数 27%（标准差 10%），纽约心脏协会功能分级 II-III 级。

方法

进行了自行车测试、6 分钟步行测试（6MWT）和肌肉耐力测试。使用计步器和国际体力活动问卷（IPAQ）评估身体活动，使用短表 36 项健康调查（SF-36）评估 HRQoL。患者随机分为对照组和干预组。干预措施包括每周两次的个性化小组运动计划，持续 3 个月。对照组患者被要求继续其日常生活。

结果

共有 42 例患者完成了研究，6 例退出。干预后每日步数没有显著增加（p = 0.351），但 IPAQ 评分增加（p = 0.008）。运动耐量（p = 0.001）、6MWT（p = 0.014）、肩外展（p = 0.028）、脚跟抬高（p < 0.0001）和 HRQoL（p = 0.018）在干预组与对照组相比均显著改善。
