The objective of this study was to investigate the effect of a 3-mo training program for patients with either a percutaneous transluminal coronary angioplasty (PTCA) or a coronary artery bypass grafting (CABG).
Forty-four patients participated in a 3-mo outpatient cardiac rehabilitation program. Graded exercise tests with gas analysis were conducted before and after training to evaluate the changes of cardiorespiratory function.
In the pretraining examination, the PTCA group showed a higher peak oxygen uptake (VO2peak) and work rate than the CABG group. In the posttraining examination, the PTCA group increased 14.6% in VO2peak. Meanwhile, the CABG group increased 32.8% in VO2peak. At the ventilatory threshold, both groups also significantly increased in Vo2.
A 3-mo cardiac rehabilitation program for patients with PTCA or CABG could favorably enhance their cardiorespiratory function. Although the pretraining VO2peak was lower for the patients with CABG, their training potential was greater, and hence they could achieve a similar level of aerobic capacity as the PTCA group.
本研究的目的是调查为期3个月的训练计划对接受经皮腔内冠状动脉成形术（PTCA）或冠状动脉旁路移植术（CABG）患者的影响。
44名患者参加了为期3个月的门诊心脏康复计划。在训练前后进行了带气体分析的分级运动测试，以评估心肺功能的变化。
在训练前检查中，PTCA组的峰值摄氧量（VO2peak）和工作负荷高于CABG组。在训练后检查中，PTCA组的VO2peak增加了14.6%。同时，CABG组的VO2peak增加了32.8%。在通气阈值时，两组的Vo2也显著增加。
为期3个月的针对PTCA或CABG患者的心脏康复计划可以有效地增强他们的心肺功能。尽管CABG患者训练前的VO2peak较低，但其训练潜力更大，因此他们可以达到与PTCA组相似的有氧运动能力水平。
