【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(P0.05);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(P0.05),且均优于对照组(P0.05);中等强度运动组与对照组LVEF差异并无显著性(P0.05),但均与高强度运动组有显著差异(P0.05);AT仅高强度运动组比对照组明显增高(P0.05)。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。
[Abstract]:Objective: to investigate the effects of different intensity aerobic exercise on cardiac function and exercise endurance after percutaneous coronary intervention (PCI). Methods: 65 patients after PCI were randomly divided into two groups: high intensity (80% peak power) intermittent aerobic exercise group (22 cases), moderate intensity (60% peak power) aerobic exercise group (21 cases) and control group (22 cases). In the high intensity exercise group, 10 groups were trained for 40 minutes with 3min training for 1 minute. The patients in the moderate intensity exercise group were trained for 12 weeks 3 times a week for 40 min. Echocardiography and cardiopulmonary exercise test (CPETs) were performed before and after training to evaluate the cardiac function and exercise endurance of the patients. Results: before training, there were no significant differences in left ventricular ejection fraction (LVEFV), peak power (PPV), duration of exercise (EDV), peak oxygen uptake (VO _ 2peaka), and anaerobic threshold (ATT) in the three groups before training, and there was no significant difference between the high intensity exercise group and the moderate intensity exercise group after training (P < 0.05). There was no significant difference in LVEF between the moderate exercise group and the control group, but there was significant difference between the high intensity exercise group and the high intensity exercise group, only the high intensity exercise group was significantly higher than the control group. Conclusion: compared with moderate intensity continuous aerobic exercise, high intensity intermittent aerobic exercise can improve the left ventricular systolic function and aerobic metabolism of patients after PCI, and improve the exercise endurance of the patients.
