摘 要:目的分析无心肌梗死患者平板运动试验(TET)诱发心电图ST段抬高与冠状动脉狭窄的关系。方法回顾性选取2008年8月至2018年8月在首都医科大学附属北京安贞医院行诊断性TET检查出现ST段抬高并进一步行冠状动脉造影(CAG)检查的无心肌梗死患者22例。分析TET心电图ST段抬高与CAG检查冠状动脉狭窄的关系。结果22例患者中,1例(4.5%)冠状动脉正常;12例(54.5%)为单支病变,其中9例左前降支狭窄,3例右冠状动脉狭窄;5例(22.7%)为双支病变,其中1例是左前降支+右冠状动脉狭窄,2例左前降支+左回旋支狭窄,2例是左回旋支+右冠状动脉狭窄;4例(18.2%)为多支病变,均为左前降支+左回旋支+右冠状动脉狭窄。22例患者中11例胸导联ST段抬高,CAG显示均有左前降支病变,狭窄程度为50%~90%;8例Ⅱ和/或Ⅲ和/或aVF导联ST段抬高,CAG显示其中6例有右冠状动脉病变,狭窄程度为70%~100%,1例左前降支中段肌桥,对角支70%狭窄,1例只有左回旋支远段20%~30%狭窄;1例V1及aVR导联ST段抬高提示多支病变,CAG显示左前降支中段狭窄80%,对角支狭窄70%,左回旋支近段狭窄60%,钝缘支近段狭窄80%,右冠状动脉远段狭窄99%;1例V1及Ⅲ导联ST段抬高,CAG显示第一对角支近段狭窄40%,左回旋支近段狭窄50%,右冠状动脉开口狭窄90%;1例aVL导联ST段抬高,CAG显示左前降支中段狭窄90%,左回旋支中段狭窄85%。结论无心肌梗死患者TET诱发心电图ST段抬高多数与冠状动脉狭窄密切相关,需要高度重视。Objective To analyze the relationship between ST-segment elevation induced by treadmill exercise test(TET)and coronary artery stenosis in patients without myocardial infarction.Methods Totally 22 patients with ST-segment elevation who underwent diagnostic TET and then underwent coronary angiography(CAG)in Beijing Anzhen Hospital,Capital Medical University from August 2008 to August 2018 were retrospectively selected.The relationship between ST-segment elevation induced by TET and coronary artery stenosis in CAG was analyzed.Results Among the 22 patients,1 case(4.5%)had normal coronary artery;12 cases(54.5%)had single vessel disease,including 9 cases of left anterior descending artery stenosis and 3 cases of right coronary artery stenosis;5 cases(22.7%)were double vessel disease,including 1 case of left anterior descending branch+right coronary artery stenosis,2 cases of left anterior descending branch+left circumflex branch stenosis,and 2 cases of left circumflex branch+right coronary artery stenosis;4 cases(18.2%)were multivessel lesions,with left circumflex branch+left circumflex branch+right coronary artery stenosis.Among the 22 patients,11 cases had ST-segment elevation in the thoracic lead,and CAG showed left anterior descending branch lesions,with a stenosis degree of 50%-90%;in 8 cases with ST-segment elevation in leadsⅡand/orⅢand/or aVF,CAG showed that 6 of them had right coronary artery disease,with a stenosis degree of 70%-100%,1 case had a muscle bridge in the middle of the left anterior descending branch,70%stenosis in the diagonal branch,and 1 case had only 20%-30%stenosis in the distal segment of the left circumflex branch;one case with ST-segment elevation in leads V1 and aVR was suggested multi vessel disease,and CAG showed 80%stenosis in the middle of the left anterior descending branch,70%stenosis in the diagonal branch,60%stenosis in the proximal left circumflex branch,80%stenosis in the proximal blunt branch,and 99%stenosis in the distal right coronary artery;one case with ST-segment eleva
