摘　　要：目的探讨运动试验ST/HR滞后与冠状动脉病变程度的关系。方法拟诊冠心病(CHD)患者186例2周内行活动平板运动试验与冠状动脉造影检查,根据冠状动脉造影结果分为冠心病组和非冠心病组,比较2组活动平板运动试验ST/HR滞后值与冠状动脉病变的程度。结果 ST/HR滞后值(≥0.01μv·bp^(-1)·min^(-1))CHD组明显高于非CHD组,p<0.01;而METs明显低于非CHD组,p<0.01。随冠状动脉病变严重程度的增加,运动ST/HR滞后值逐渐增大,ST/HR滞后值≥0.01μv·bp^(-1)·min^(-1),1支血管病变23.58%;ST/HR滞后值≥0.025μv·bp^(-1)·min^(-1),2支血管病变33.00%;ST/HR滞后值≥0.045μv·bp^(-1)·min^(-1),3支血管病变43.39%,血管病变支数与病例比较,p<0.05。运动ST/HR滞后值与ST段压低值及冠状动脉病变严重程度均呈正相关;运动最大代谢当量(METs)与ST段压低及冠状动脉病变严重程度呈负相关。结论冠心病患者运动ST/HR滞后增大可反映心肌缺血及冠状动脉病变程度的指标。Objective To study the relationship between the result of extent of treadmill exercise test value the maxinal ST segment/heart rate hysteresis(ST/HR hysteresis)and coronary angiography. Methods One hundred and eighty-six patients with suspected coronary artery disease received treadmill exercise test value the maxinal ST segment/heart rate hysteresis and coronary angiography in two weeks,and were divided into coronary artery disease group and non-coronary artery disease group according to the result of coronary angiography. The value the maxinal ST segment/heart rate hysteresis of treadmill exercise test were compared between two groups. Results The value the maxinal ST segment/heart rate hysteresis(≥0.01μv·bp-1·min-1)coronary artery disease group was significantly higher than those in the non-coronary artery disease group, p<0.01, The METs coronary artery disease group was significantly lower than those in the non-coronary artery disease group, p<0.01;The ST segment/heart rate hysteresis of exercise had an increasing trend with the severity of coronary artery tesion. ST/HR hysteresis ≥0.01 μv·bp-1·min-1, 1 branch coronary artery vessls vessel disease were 23.58%;ST/HR hysteresis≥0.025μv·bp-1·min-1, 2 branch coronary artery vessls vessel disease were 33.00%;ST/HR hysteresis≥0.045μv·bp-1·min-1,3 branch coronary artery vessls vessel disease were 43.39%, p<0.05. The ST/HR hysteresis of exercise were positively correlated to the depression of ST segment and the severity of coronary artery lesion;The The maximal metabolic equivalents exercise test of exercise were negatively correlated to the depression of ST segment and the severity of coronary artery. Conclusions Parameter of patients with coronary artery disease had an increase ST segment/heart rate hysteresis of exercise can be one of the indexes to estimate extent of myocardial inchemia and coronary artery lesion.
