背景與目的：恢復型心收縮分率心衰竭(heart failure recovered ejection fraction, HFrecEF)為心衰竭的一項新類類別，是指一開始診斷為低收縮分率心衰竭，其心室射出分率因自然恢復或治療後上升至>40%。文獻指出HFrecEF族群之存活率、再住院率及心肺耐力皆優於其他三類，為預後較佳族群。本文利用個案報告提供恢復型心收縮分率心衰竭物理治療運動訓練參考。方法：個案為一位39歲男性，因感到呼吸困難以及胸口不適而就醫，接受心導管與心肌切片檢查，而確診為擴張型心肌病變，給予藥物調整，於出院後，並參與「急性後期整合照護計畫」轉介開始第二期心臟復健。本文使用「個案處理模式」與「國際健康功能與身心障礙分類系統」進行心衰竭個案分析。結果：由於個案屬於低收縮分率心衰竭，物理治療計畫前18次運動訓練，依美國運動醫學會建議運動危險分級，左心室射出分率小於35%為運動高危險群，故以中等強度運動訓練，40~60%心率儲存量設定運動強度，每週兩次之有氧運動及阻力運動，後18次運動訓練，由於其運動心肺功能測試與心室射出分率皆有進步，屬於HFrecEF族群，為心衰竭中預後較佳的族群，且病人運動動機強，因此調整為高強度間歇性運動訓練，運動訓練後，個案運動心肺功能測試之最大強度為7.1代謝當量，左心室射出分率皆有進步為53.4%。結論：本個案報告為首次針對HFrecEF族群執行中等強度運動訓練，並轉銜高強度間歇性運動訓練，藉此供臨床物理治療運動訓練參考。

Background and Purpose: Heart failure recovered ejection fraction (HFrecEF) is a new population whose EF improve from HFrEF to HFmrEF and even normalize their EF to ≥ 50%. Survival rate, re-admission rate, exercise capacity and exercise tolerance of HFrecEF are better than these of other three groups. This article offers a suggestion of exercise program in a HFrecEF patient by case report. Methods: The case is a 39-year-old man diagnosed with dilated cardiomyopathy. He suffered from chest tightness and dyspnea on exertion. The coronary angiography and biopsy showed dilated cardiomyopathy and HF-related medicines were given. He was referred to cardiac rehabilitation phase II program was started in the fourth week after discharge by the post-acute care plan. This article reported a case by using the Client Management Model and international classification of functioning, disability and health. Results: Exercise intensity was set by heart rate reserved (HRR) according to American Medical Association. Cardiac rehabilitation included aerobic and resistant training twice a week. The first 18 times exercise training, he performed the exercise for 20 mins at 40–60% HRR, due to the case was HFrEF. The exercise capacity and EF improved to HFmrEF. Thus the case belonged to HFrecEF which had better recovery. He had high motivation of exercise. The next 18 times exercise training was high intensity interval training for four 3-minute intervals at 80% HRR, and each interval was separated by 3-minute exercise at 40% HRR. After cardiac rehabilitation, peak METs improved 5.1–7.1 METs, and EF increased 28.5–53.4%. Conclusion: This case report is the first application of exercise program from moderate-intensity transferred to high-intensity interval training to HFrecEF, which offers a valuable suggestion for clinical physical therapy.
