摘要

目的：評估心臟復健計畫對於已接受冠狀繞道手術(CABG)病患之休息心跳的影響。方法：22位已接受冠狀動脈繞道手術(CABG)病患隨機安排至心臟復健運動計劃組(n = 11)和控制組(n = 11)。所有的病患於出院時和三個月後執行心肺運動測試(cardiopulmonary exercise tests)，心臟復健運動計劃組的病患接受每週三次，運動強度為根據心肺運動測試時所達到最大心跳之60-85%，總共36次耐力運動訓練。結果：於三個月後之心肺運動測試，心臟復健運動計劃組相較於控制組的病患顯現出明顯較低的休息心跳(75.4 ± 8.1 下/分 P=0.018)。另外，對於2組病患，相較於其出院時後均顯現出明顯較低的心跳(心臟復健組P=0.006；控制組P=0.020)。結論：心臟復健計劃對於接受冠狀動脈繞道手術(CABG)病患之休息心跳有正面的影響，已結果與自主神經系統的改善一致。

Objective. To evaluate the effects of cardiac rehabilitation on the resting heart rate in patients who received coronary artery bypass graft (CABG) surgery. Method. Twenty-two patients who received CABG were randomly assigned to enter or not to enter a cardiac rehabilitation exercise program (cardiac rehabilitation n = 11; control group n = 11). All subjects underwent cardiopulmonary exercise tests at discharge and 3 months later. Patients in cardiac rehabilitation group received 36 sessions of exercise program, 3 times a week, and the intensity was designed according to individual 60-85% of peak heart rate achieved in cardiopulmonary exercise test. Results. At follow-up tests, patients in the cardiac rehabilitation group had a significantly lower resting heart rate (75.4 8.1 beats/min) compared to that of control group (P=0.018). There were also significant reductions in resting heart rates in both cardiac rehabilitation (P=0.006) and control groups (P=0.020) compared to their baseline measurements Conclusion. Cardiac rehabilitation exercise program had a positive effect on heart rate recovery in CABG patients, and this result was consistent with the autonomic improvement.
