Patients with heart failure with preserved ejection fraction (HFpEF) experience poor exercise tolerance and quality of life. Little is known about the feasibility or effects of HFpEF exercise training (ET) in a community hospital setting.
The aim of this study was to examine the feasibility and pilot data of a community-based HFpEF ET intervention.
This was a single-group (n = 16), pretest-posttest, 9-week ET intervention. The Minnesota Living With Heart Failure Questionnaire, Patient Health Questionnaire-9, cardiopulmonary exercise test (peak VO2), and 6-minute walk test were used for evaluation.
Participants (n = 16) attended 88% of prescribed ET sessions and 94% completed all pretest-posttest assessments. Significant improvements in Minnesota Living With Heart Failure Questionnaire (P = .01), Patient Health Questionnaire-9 (P ≤ .01), exercise test time (P = .01) and 6-minute walk test (P = .001), but not in peak VO2 (P = .16), were found.
The ET intervention was feasible and safe, and findings support improved quality of life, depressive symptoms, and exercise tolerance. Larger controlled trials are warranted.
射血分数保留的心力衰竭（HFpEF）患者运动耐量和生活质量较差。HFpEF 运动训练（ET）在社区医院环境中的可行性或效果知之甚少。
本研究旨在探讨基于社区的 HFpEF ET 干预的可行性和初步数据。
这是一项单组（n = 16）、前测后测、9 周 ET 干预研究。采用明尼苏达州心力衰竭生活质量问卷、患者健康问卷-9、心肺运动试验（峰值 VO2）和 6 分钟步行试验进行评估。
参与者（n = 16）参加了 88%的规定 ET 课程，94%的参与者完成了所有的前测后测评估。明尼苏达州心力衰竭生活质量问卷（P =.01）、患者健康问卷-9（P ≤.01）、运动试验时间（P =.01）和 6 分钟步行试验（P =.001）显著改善，但峰值 VO2 无显著改善（P =.16）。
ET 干预是可行且安全的，研究结果支持改善生活质量、抑郁症状和运动耐量。需要更大规模的对照试验。
