个体化运动康复治疗对未行血运重建的冠心病患者的影响

目的:观察6min步行试验指导的个体化运动康复治疗对未行血运重建的冠心病患者心功能、生活质量及近期预后的影响。方法:选择在我院心内科住院治疗,且经冠脉造影证实至少一支或多支冠状动脉血管狭窄≥75%,但未接受血运重建的冠心病患者200例为研究对象。分为常规药物治疗(A组)和常规药物治疗+运动康复治疗(B组)各100例。2组患者均给予常规冠心病药物治疗,且在出院后每周来医院接受健康教育,B组患者在此基础上加用个性化运动康复治疗方案。结果:治疗8周后,B组患者心力衰竭、再发心肌梗死率及死亡发生率均明显低于A组(P<0.05)。治疗后,2组静息室壁运动积分及生活质量评分均较出院时明显下降(P<0.05),且B组较A组下降更明显(P<0.05);2组左室射血分数及6min步行距离均较出院时明显提高(均P<0.05),且B组较A组提高更明显(P<0.05)。结论:6min步行试验指导的个体化运动康复治疗可明显改善未行血运重建的冠心病患者心功能、生活质量及近期预后。

Effect of individualized exercise rehabilitation in patients with coronary heart disease without revascularization

Objective:To investigate the effect of individualized exercise therapy guided by 6-minute walking test on cardiac function, quality of life and short-term prognosis in patients with coronary heart disease without revascularization.Methods:The patients who were hospitalized in the Department of Cardiology of our hospital and confirmed by coronary angiography that there was at least one or more coronary artery stenosis more than 75%, but not given vascularization of the coronary artery were selected for study. They were divided into routine drug therapy group (group A) and routine drug therapy plus exercise rehabilitation group (group B). Patients in group B received rehabilitation exercise guided by 6 minute walk test. The quality of life, cardiac function and prognosis of the two groups were compared after treatment for 8 weeks.Results:After 8 weeks of treatment, the heart failure rate, recurrent myocardial infarction rate and mortality were significantly lower in group B than in group A (P<0.05). After treatment, the resting wall motion scores and quality of life scores in the two groups significantly decreased as compared with those at the time of discharge (P<0.05), and those in the group B decreased more obviously than in the group A (P<0.05); the left ventricular ejection fraction in the two groups and the distance of 6 min walking test were significantly improved as compared with those at the time of discharge (P<0.05), and those in the group B were improved more obviously than in the group A.Conclusion: The individualized exercise therapy guided by 6 minute walk test can obviously improve the heart function, quality of life and the short term prognosis of patients with coronary heart disease without revascularization.
