摘要
目的结合冠状动脉造影评价心电图在诊断冠心病中的价值。方法156例临床诊断冠心病的患者,均记录18导联心电图(ECG),部分患者行运动心电图检查,继之行冠状动脉造影(CAG),部分患者同时接受冠状动脉内介入治疗。结果心电图诊断冠心病的灵敏度为78.6%;特异性36.1%;假阳性率63.9%;假阴性率19.7%;阳性预测值58.9%;阴性预测值为59.1%。CAG前ECG有缺血性改变的患者中,CAG未见明显管腔狭窄占43.4%(49/113);临床有发作性胸痛,ECG无缺血性改变的患者中,CAG显示相应血管有粥样硬化狭窄者40%(17/42);CAG显示3支血管病变,ECG无缺血性改变的占19.4%(7/36)。结论心电图是诊断冠心病的有效手段,但有一定的局限性,应重视冠状动脉造影检查。
[Objective] To evaluate the diagnostic value of coronary heart disea se by electrocardiogram combined with angiography. [Methods] 156 patients ,cli nical diagnosed coronary heart disease (CHD), aged fromed 30 to 78 years old (av erage 58±12 years old), were commonly recorded 18 leads electrocardiogram, some accepted treadmill. All the patients accepted coronary angiography (CAG), some of them accepted percutaneous coronary intervention (PCI). [Results] Using ele ctrocardiogram to diagnose CHD, the positive rate was 78.6%; speciability was 36 .1%; false positive rate was 63.1%; false negative rate was 19.7%; positive pre diction was 58.9%; negative prediction was 59.1%. In the patients whose electroc ardiogram had ischemic changes, CAG had no stenosis accounted for 43.4%(49/113); In the patients whose electrocardiogram had no ischemic changes but had chest p ain, CAG had corresponding vessel atherosclerosis accounted for 40%(17/42); In t he patients whose CAG showed three vessels stenosis, but the ECG had no ischemic changes accounted for 19.4%(7/36). [Conclusions] Electrocardiogram is an effe ctive method to diagnose coronary heart disease, but it has a little limitation. It is important to take coronary angiography seriously.
