平板运动试验心率恢复及心率变异性与冠心病的相关分析

Correlation between of heart rate recovery after treadmill exercise test to patients with coronary artery disease and heart rate variability

目的评价平板运动试验后心率恢复、心率变异性与冠心病的关系及临床意义。方法对310例拟诊为冠心病的患者行活动平板运动试验,并对照其冠状动脉造影结果,将患者分为冠心病组106例和非冠心病组204例。比较两组患者的心率恢复值、达标时间、静息心率及运动最大心率,分析心率恢复异常与冠心病。同时评估短期心率变异性。结果冠心病组运动后心率恢复值低于非冠心病组,差异有统计学意义;冠心病组心率变异性与非冠心病组相比,差异有统计学意义。结论冠心病组与非冠心病组相比,心率恢复异常及心率变异性差异均有统计学意义,两者综合评价冠心病的准确率更高。

Objective To evaluate the significance of heart rate recovery（ HRR）,heart rate variability（ HRV） after treadmill exercise test and its clinical value in coronary heart disease（ CAD）.Methods 310 cases of suspicious coronary artery disease who underwent treadmill exercise test were divided into CAD group and non-coronary artery disease（ NCAD） group according to coronary artery angiogram. HRR value of the two groups were compared,the standard time,resting heart rate and exercise maximum heart rate,abnormal HRR as a diagnostic criterion for CAD,Compare its accuracy with treadmill exercise test in the diagnosis of CAD. Simultaneous analysis of short-term HRV. Results HRR after CAD is lower than the NCAD group,the difference was significant;CAD rate variability compared with non-CAD group,the difference was statistically significant.Conclusion CAD group compared with the non-CAD group,HRR and HRV significantly differs,can be used to diagnose CAD.
