影响平板运动试验心率恢复的相关因素分析

Related factors analysis of heart rate recovery after treadmill exercise test

目的探讨影响平板运动试验(treadmill exercisetest,TET)后心率恢复的相关因素。方法回顾性分析2008年5月～2012年5月在我院做TET并经冠状动脉造影(coronary angiography,CAG)确诊或排除冠心病的150份病例。根据TET中是否发生心率恢复异常(运动后第1分钟心率恢复<18次/min)分为心率恢复异常组(A组)及心率恢复正常组(B组),并收集各项临床观察指标进行分析。结果男性、体质量超重、吸烟、基础心率偏快、伴随冠心病(尤其是多支病变者)、伴随糖尿病及焦虑症者均可影响运动后的心率恢复。结论控制体质量、戒烟、降低过快的基础心率、重视精神障碍的心理干预、重视糖尿病者的自主神经功能检测、加强冠心病者的双心治疗对心血管疾病的防控具有重要的临床意义。

Objective To explore the related factors which influence heart rate recovery after treadmill exercise test(TET).Methods Give a retrospective analysis of 150 cases who were carried out TET in our hospital during May 2008-May 2012 and were diagnosed with or excluded from coronary disease by undergoing coronary angiography(CAG).According to the occurrence of abnormality in heart rate recovery during TET,all patients were divided into two groups:abnormal-heart-rate-recovery group(group A)and normal-heart-rate-recovery group(group B),where the abnormality in heart rate recovery was defined if the recovery of heart rate the first minute after exercises was less than 18 time per minute.Various clinical observation indexes of these patients were analyzed.Results Related factors of heart rate recovery after TET include being male,overweight,smoking,relatively fast basal heart rate,being complicated with coronary disease(especially multiple vessel disease),diabetes or anxiety.Conclusion In the prevention and control of cardiovascular disease,it bears great clinical significance to control weight,quit smoking,slow down the basal heart rate,pay more attention to psychological intervention of mental disorders as well as function test of autonomic nerve of diabetes mellitus,and strengthen double heart treatment of coronary disease.
