有氧运动干预对老年稳定性冠心病患者认知功能损伤改善作用

Effect of aerobic exercise intervention on cognitive impairment in elderly patients with stable coronary heart disease

目的探讨有氧运动干预对老年稳定性冠心病患者认知功能的改善作用。方法选取64例合并有认知功能损伤的老年稳定性冠心病患者作为研究对象,通过随机数法分成有氧运动干预组和对照组各32例。有氧运动干预组患者在常规治疗基础上进行有氧运动干预,对照组患者仅采取常规治疗。采用蒙特利尔认知评估量表(MoCA)评估认知功能,比较两组患者在干预前后认知功能的变化。结果两组患者干预前基线水平MoCA各方面评分比较均无统计学差异存在(P>0.05)。有氧组患者给有氧运动干预4个月后,MoCA各方面评分均有所增加,在视空间及执行能力、注意及总分值方面存在显著统计学差异(P<0.05)。对照组患者在4个月后,MoCA各方面评分均未出现明显的统计学差异(P均>0.05)。有氧组患者有氧运动干预4个月后与对照组患者相比,MoCA评分在命名、注意及总分方面要明显优于对照组,差异有统计学意义。结论有氧运动干预能够对老年稳定性冠心病患者的认知功能损伤起到改善作用。

Objective To explore the effect of aerobic exercise intervention on cognitive function in elderly patients with stable coronary heart disease.Methods 64 elderly patients with stable coronary heart disease(CHD)with cognitive impairment were selected as the study subjects.They were divided into aerobic intervention group and control group by random number method,32 cases each.Patients in the aerobic exercise intervention group received aerobic exercise intervention on the basis of routine treatment,while patients in the control group only received routine treatment.Montreal Cognitive Assessment Scale(MoCA)was used to assess cognitive function.The changes of cognitive function before and after intervention were compared between the two groups.Results There was no significant difference between the two groups in all aspects of MOCA before intervention(P>0.05).After 4 months of aerobic exercise intervention,MOCA scores increased in all aspects,and there were significant differences in visual space,executive ability,attention and total scores(P<0.05).After 4 months,there was no significant difference in MOCA scores of the control group(P>0.05).After 4 months of aerobic exercise intervention,MOCA scores of patients in aerobic group were significantly better than those in control group in terms of naming,attention and total scores.Conclusion Aerobic exercise intervention can improve cognitive impairment in elderly patients with stable coronary heart disease.
