有氧锻炼联合抗阻训练对冠心病致心肌缺血患者的影响

Effects of aerobic exercise combined with resistance training on patients with myocardial ischemia caused by coronary heart disease

目的探讨长期有氧锻炼联合抗阻训练在冠心病致心肌缺血患者中的临床效果及对心功能、运动耐力及生活质量的影响。方法选择2017年1月~2019年1月冠心病致心肌缺血患者100例作为研究对象,随机分为对照组(n=50)和观察组(n=50)。对照组给予抗阻训练,观察组在对照组基础上联合长期有氧锻炼,两组均完成3个月治疗,比较两组心功能、运动耐力及生活质量。结果观察组治疗后3个月舒张期间隔厚度(IVST)、左心室舒张末期内径(LVDD)及左心室收缩末期内径(LVSD)水平低于对照组,观察组治疗后3个月左心室射血分数(LVEF)水平高于对照组,两组比较差异具有统计学意义(P<0.05),观察组治疗后的ET、TXB2水平明显低于对照组,两组比较差异具有统计学意义(P<0.05)。观察组治疗后3个月6 min步行距离、生活质量评分高于对照组,两组比较差异具有统计学意义(P<0.05)。结论长期有氧锻炼联合抗阻训练用于冠心病所致心肌缺血患者中能提高患者心功能水平,提高运动耐受力及生活质量,值得推广应用。

Objective To explore the clinical effect of long-term aerobic exercise combined with resistance training in patients with myocardial ischemia caused by coronary heart disease and its influence on cardiac function,exercise endurance and quality of life.Methods Totally 100 patients with myocardial ischemia caused by coronary heart disease from January 2017 to January 2019 were randomly divided into control group(n=50)and observation group(n=50).The control group was given resistance training,while the observation group was combined with long-term aerobic exercise on the basis of the control group.The two groups were treated for 3 months.The cardiac function,exercise endurance and quality of life were compared between the two groups.ResultsThe levels of IVST,LVDD and LVSD in the observation group were lower than those in the control group at 3 months after treatment.The level of LVEF in the observation group was higher than that in the control group at 3 months after treatment.The difference between the two groups was significant(P<0.05).The ET in the observation group was higher than that in the control group(P<0.05).2)The levels of ET and TXB2 were significantly lower than those of the control group,and the difference between the two groups was statistically significant(P<0.05).The 6-minute walking distance and the quality of life score in the observation group were higher than those in the control group 3 months after treatment,and the difference between the two groups was statistically significant(P<0.05).Conclusion Long-term aerobic exercise combined with resistance training can improve cardiac function,exercise tolerance and quality of life in patients with myocardial ischemia caused by coronary heart disease,which is worthy of popularization and application.
