201例老年慢性心力衰竭患者6MWT步行试验反应的临床资料分析

Clinical Analysis of 6MWT Walking Test Reaction in 201 Elderly Patients with Chronic Heart Failure

摘要: 为提高老年慢性心力衰竭患者康复运动处方治疗的效果及其安全性。方法：对临床诊断为老年慢性心力衰竭，经过临床治疗，症状明显好转，准备进行康复期运动处方治疗的患者201例，询问病史检测身高、体重、血压、血脂、血糖，进行6MWT试验。结果：老年慢性心力衰竭患者6MWT达标与心功能、肥胖、高血压和糖尿病有关，心功能 ≥ 3级、肥胖、高血压和糖尿病的患者6MWT达标率比较低，其高体重、高体重指数、高血压、高血糖、高胆固醇和高甘油三酯患者6MWT达标率比较低。未达标组患者运动后QRS间期延长大于达标组患者。提示老年慢性心力衰竭患者其心血管疾病高危因素聚集，患者运动后心率明显减慢。结论：6MWT歩行在450 M以内的老年慢性心力衰竭患者，其基础疾病控制不好，其在康复期间应当慎用运动处方。

Abstract: Objective: To improve the efficacy and safety of rehabilitation exercise prescription in elderly patients with chronic heart failure. Methods: 201 patients with chronic heart failure, who were clinically diagnosed as chronic heart failure and whose symptoms were obviously improved after clinical treatment, were prepared for rehabilitation exercise prescription treatment, the height, weight, blood pressure, blood lipid and blood glucose were measured and 6MWT test was carried out. Results: The 6MWT was related to heart function, obesity, hypertension and diabetes mellitus in elderly patients with chronic heart failure. The 6MWT was lower in patients with heart function ≥ 3, obesity, hypertension and diabetes mellitus. The level of 6MWT in elderly patients with chronic heart failure is related to their constitution, blood pressure, blood glucose and blood lipid, patients with high body weight, high body mass index, high blood pressure, high blood sugar, high cholesterol and high triglycerides had lower 6MWT compliance rate. The prolongation of QRS interval after exercise was greater in the patients without QRS than in the patients with QRS. It is suggested that the high risk factors of cardiovascular disease in the elderly patients with chronic heart failure gather together, and the heart rate of the patients obviously slows down after exercise. Conclusion: the 6MWT can not control the underlying diseases well and the cardiovascular risk factors are clustered in the elderly patients with chronic heart failure, so exercise prescription should be used carefully during the rehabilitation period.
