Twenty-nine patients with documented coronary artery disease underwent cardiopulmonary exercise tests before and following a percutaneous transluminal coronary angioplasty (PTCA). The patients medication regimen and exercise protocols remained the same in both cases. Following PTCA, significant improvement (p < 0.001-0.0001) was noted in oxygen consumption (1,526.8 +/- 470.0 vs. 1,686.2 +/- 390 ml/min), oxygen pulse (12.40 +/- 2.73 vs. 13.44 +/- 2.9 ml/beat), oxygen pulse score (7.62 +/- 1.29 vs. 8.85 +/- 1.26 points) and in the ventilatory anaerobic threshold (993.1 +/- 177.6 vs. 1,089.8 +/- 150.9 ml/min) but not (p > 0.05) in maximal heart rate (128.7 +/- 16.9 vs. 132.0 +/- 17.2 beats/min). Thus, a cardiopulmonary exercise test is an effective method to assess functional results following PTCA.
29例有冠状动脉疾病记录的患者在经皮腔内冠状动脉成形术（PTCA）前后接受了心肺运动试验。两种情况下患者的用药方案和运动方案均保持不变。PTCA后，耗氧量（1526.8±470.0对1686.2±390毫升/分钟）、氧脉搏（12.40±2.73对13.44±2.9毫升/次搏动）、氧脉搏评分（7.62±1.29对8.85±1.26分）以及通气无氧阈（993.1±177.6对1089.8±150.9毫升/分钟）均有显著改善（p<0.001 - 0.0001），但最大心率无显著变化（p>0.05）（128.7±16.9对132.0±17.2次/分钟）。因此，心肺运动试验是评估PTCA后功能结果的有效方法。
