摘要
目的:探讨不同强度有氧运动对经皮冠状动脉介入治疗(PCI)术后患者心功能及运动耐力的影响。方法:将65例PCI术后患者随机分为高强度(峰值功率的80%)间歇有氧运动组(22例)、中等强度(峰值功率的60%)有氧运动组(21例)、对照组(22例)。高强度运动组以3min训练、1min休息的间歇训练模式进行,每次训练10组,共40min。中等强度运动组每次持续训练40min,两组患者均训练12周,每周3次,所有患者训练前后均行超声心动图及心肺运动试验(CPET)评估患者心功能及运动耐力。结果:训练前3组患者的左室射血分数(LVEF)、峰值功率(PP)、运动持续时间(ED)、峰值摄氧量(VO2peak)、无氧阈(AT)均无显著差异(P>0.05);训练后高强度运动组及中等强度运动组PP、ED、VO2peak比较差异具有显著性(P<0.05),且均优于对照组(P<0.05);中等强度运动组与对照组LVEF差异并无显著性(P>0.05),但均与高强度运动组有显著差异(P<0.05);AT仅高强度运动组比对照组明显增高(P<0.05)。结论:与中等强度持续有氧运动相比,高强度间歇有氧运动可以更好地改善PCI术后患者的左室收缩功能及有氧代谢能力,提高患者的运动耐力。
Objective：To investigate the effects of different intensity aerobic exercise on cardiac function and exercise endurance in patients after percutaneous coronary intervention（PCI）.Method：Sixty-five patients after PCI were randomly divided into high-intensity（80% of peak power） intermittant aerobic exercise group（n=22）, moderate-intensity（60% of peak power） aerobic exercise group（n=21） and control group（n=22）. High-intensity exercise training group performed by the mode of 3min training separated by 1min of rest, 10 sessions every time,each time lasted 40 min, moderate- intensity exercise group accepted40 min persistent training every time. All patients trained for 12 weeks, 3 times a week, before and after training, all patients received echocardiography and cardiopulmonary exercise test（CPET） to assess their cardiac function and exercise endurance.Result：Before training, 3 groups of patients had no significantly difference（P〉0.05） in left ventricular ejection fraction（LVEF）, peak power（PP）, exercise duration（ED）, peak oxygen uptake（VO2peak） and anaerobic threshold（AT）; after training, there were significant differences（P〈0.05） between high- intensity exercise groupand moderate- intensity exercise group in PP, ED, VO2 peak, and all were better than control group（P〈0.05）;moderate- intensity exercise group and control group had no significant difference in LVEF（P〉0.05）, but there were significant differences（P〈0.05） to high-intensity exercise group; only high-intensity group had significantly higher AT than control group（P〈0.05）.Conclusion： Compared with continuous moderate- intensity aerobic exercise, high- intensity intermittent aerobic exercise can better improve left ventricular systolic function and aerobic metabolism ability of patients after PCI, and improve their exercise tolerance.
