| 摘要
目的：检测肥胖对心肌梗死后（PMI）患者心脏康复早期有氧工作能力的影响。
方法：116例男性PMI患者根据其身体质量指数（BMI）高于或低于25和服用或未服用β-阻断剂被分为4组，然后进行递增负荷运动实验，其间记录每级负荷时的摄氧量（VO2）、心率（HR）、血压和自我用力感觉（RPE），并持续监测12导联心电图（ECG）。
结果：BMI＜25的两组患者都能坚持较长时间的运动（P＜0.05），有较高的峰值摄氧量（P＜0.05）和较低的有氧能力的损伤(P＜0.01)。当RPE到达13时，其他组别的VO2分别是BMI＜25且服用β-阻断剂组的90%（未服用β-阻断剂，BMI＜25），75%（服用β-阻断剂，BMI＞25）和70%（未服用β-阻断剂，BMI＞25）。
结论：肥胖会影响患者运动中的功能和代谢能力，但服用β-阻断剂对此可有所补偿。BMI＜25对于减轻氧能力损伤将会有明显的益处。 |

| Abstract
Objective: To examine the influence of adiposity on the aerobic capacity of post myocardial infarction (PMI) patients during early stage of cardiac rehabilitation.
Method: One hundred and sixteen male recent PMI patients were divided into four groups according to their body mass index (BMI) above or below 25, and with or without taking β-blocker. Then, a graded exercise test was performed; oxygen uptake (VO2), heart rate (HR), blood pressure and ratings of perceived exertion (RPE) were recorded, and 12 lead electrocardiogram (ECG) was monitored continuously.
Result: Both groups with BMI<25 could persist longer exercise time (P<0.05), had higher peak VO2 (P<0.05), and lower functional aerobic impairment (P<0.01). When RPE was at 13, relatively to the taking β-blocker and BMI<25 group, the other groups had peak VO2 of 90% (no、β-blocker, BMI<25), 75% (taking β-blocker, BMI>25) and 70% (no β-blocker, BMI>25) respectively.
Conclusion: Adiposity can compromise patients' function and metabolic capacity during exercise, but in patients taking β-blocker there may be some compensation. One with BMI <25 will have particular benefits for alleviating functional aerobic impairment. |
