| 目的 对比观察不同强度间歇有氧运动在急性冠脉综合征患者心脏康复中的作用（包括有效性及安全性），为科学制订运动处方提供参考依据。 方法 采用随机数字表法将64例急性冠脉综合征患者分为最大强度间歇有氧运动组（简称MAIE组）和高强度间歇有氧运动组（简称HAIE组）。2组患者先进行2周适应性训练，随后分别以95%~100%心率储备（HRR）和85%HRR进行4周相应强度间歇有氧运动，每周训练3 d。于有氧运动前、训练6周后测定2组患者最大摄氧量（VO2max）并记录其运动过程中相关不良反应情况。 结果 2组患者共合计完成671.6 h有氧运动训练，且均未出现心血管及骨骼肌肉系统并发症。经6周不同强度间歇有氧运动后，发现MAIE组、HAIE组VO2max［分别为（33.2±5.0）ml/kg/min和（30.6±4.7）ml/kg/min］均较训练前明显增加（P<0.05），并且MAIE组VO2max升高幅度（31.2%）亦显著大于HAIE组水平（17.2%），组间差异具有统计学意义（P<0.05）。 结论 在严格监控下进行MAIE运动对急性冠脉综合征患者心肺功能的改善疗效优于HAIE运动，且不同强度间歇有氧运动均具有较高安全性。 |

| Objective To evaluate the efficacy and safety of intermittent aerobic exercise of different intensities in the cardiac rehabilitation of patients with acute coronary syndrome so as to provide a reference for making the best exercise prescription. Methods Sixty-four acute coronary syndrome patients were randomly divided into a maximum-intensity and a high-intensity intermittent aerobic exercise group, each of 32. Both groups underwent 2 weeks of adaptive training, followed by 4 weeks of intermittent aerobic exercise (3d/week) at either 95-100% or 85% of their heart rate reserve. The maximum oxygen uptake (VO2max) was measured before and after the intervention, and any exercise-related adverse reactions were recorded. Results Both groups completed the 671.6-hour exercise plan without any cardiovascular or musculoskeletal complications. After the intervention, the average VO2max of the maximum-intensity group had increased by 31.2%, versus 17.2% for the high-intensity group, a significant difference. Conclusion Maximum-intensity aerobic exercise is more effective than high-intensity in improving cardiopulmonary function among patients with acute coronary syndrome. With strict monitoring, both intensities are safe. |
