영문 초록

Purpose : Higher levels of peak oxygen consumption and maximal aerobic capacity in patients with heart failure (HF) can lead to improvement of clinical outcomes such as morbidity and mortality. For this reason, cardiac rehabilitation (CR) should be applied to maximize HF patients’ aerobic capacity. However, several precautions are necessary due to unexpected cardiac adverse events in case of HF with reduced ejection fraction (HFrEF). The purpose of this study is to investigate the effect and safety of recumbent cycle exercise and regular training in order to apply a CR program for HFrEF patients. Methods : 72 HFrEF patients completed a cardiopulmonary exercise test and a knee extensor maximal voluntary isometric contraction (MVIC) and muscle power (MP) test at baseline. 12 HFrEF patients completed recumbent cycle exercise training (50 minutes, three times per week) for 24 sessions, followed by a post-test. Results : The study population consisted of 12 HFrEF patients (age 57.5± 10.8 years, all male). All subjects completed 24 training session without adverse events. Compared to baseline, the peak VO2 and six minute walking distance were significantly improved by 16% (p=0.003) and 18% (p<0.001) respectively. Knee extensor MVIC and MP weresignificantly improved by 18% (p=0.002) and 21% (p=0.012) respectively. Conclusion : Our study showed that recumbent cycle exercise could be an effective and safe exercise training method to increase aerobic capacity and leg muscle strength in HFrEF patients.
