快步走有氧运动联合抗阻训练对年轻冠心病 PCI术后患者运动耐力及心功能的影响

Effects of brisk walk aerobic exercise combined with resistance training on exercise endurance and cardiac function of young patients with coronary heart disease after PCI

目的:探讨快步走有氧运动联合抗阻训练对年轻冠心病经皮冠状动脉介入术(PCI)术后患者心功能指标及运动耐力指标的影响。方法:选取125例年轻冠心病PCI术后患者作为研究对象,采用随机数字表法将其分为试验组62例和对照组63例。对照组予以抗阻训练,试验组在对照组的基础上予以快步走有氧运动,干预后观察两组患者心功能指标及运动耐力指标情况。结果:干预后试验组左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)低于对照组(P<0.05),左心室射血分数(LVEF)高于对照组(P<0.05);峰值氧耗量(VO_(2)peak)、无氧代谢阈值氧耗量(VO_(2)AT)高于对照组(P<0.05)。结论:快步走有氧运动联合抗阻训练应用于年轻冠心病PCI术后患者中,通过降低LVEDD、LVESD水平,提高运动耐力指标LVEF、VO_(2)peak和VO_(2)AT,从而有效改善患者心功能和运动耐力。

Objective: To investigate the effects of aerobic exercise combined with resistance training on the cardiac function and exercise endurance in young patients with coronary heart disease after percutaneous coronary intervention(PCI). Methods: A total of 125 young patients with coronary heart disease who underwent PCI were selected as the research subjects. They were randomized into an experimental group(n=62)and a control group(n=63). The control group were given resistance training, while the experimental group were given aerobic exercise at a fast pace on the basis of therapy for the control group. Then the cardiac function index and exercise endurance index of the two groups were compared after the intervention. Results: After intervention, the left ventricular end diastolic diameter(LVEDD)and left ventricular end systolic diameter(LVESD)of the experimental group were lower than that of the control group(P<0.05);the left ventricular ejection fraction(LVEF)was higher than that of the control group(P<0.05);and peak oxygen consumption(VO_(2)peak)and oxygen consumption of anaerobic threshold(VO_(2)AT)were higher than those in the control group(P<0.05). Conclusion: For young patients with coronary heart disease after PCI, Brisk walk aerobic exercise combined with resistance training can reduce LVEDD and LVESD levels, increase the exercise endurance indexes of LVEF, VO_(2)peak and VO_(2)AT, and effectively improve patients’ cardiac function and exercise endurance.
