12导联动态心电图对老年冠心病患者的诊断价值

目的　评价 12导联动态心电图对老年冠心病的诊断价值。方法　选择 10 0例临床疑为冠心病的老年患者 ,将12导联动态心电图检测心肌缺血的结果与冠状动脉造影结果进行对比分析。结果　 12导联动态心电图诊断冠心病的敏感性为 6 3.8% ,特异性为 79.2 % ,阳性预测值为 73.2 % ,阴性预测值为 71.2 % ,准确性为 72 %。 12导联动态心电图对于 3支及左主干病变敏感性高达 10 0 % ,而对于前降支、回旋支或右冠状动脉病变敏感性没有区别。结论　 12导联动态心电图在诊断老年冠心病方面敏感性及特异性不高 ,但对左主干及 3支病变的敏感性很高 ,有一定的临床应用价值

The value of 12-lead dynamic electrocardiography in the diagnosis of coronary artery disease in the elderly

s:Objective To assess the value of 12 lead dynamic electrocardiography (Holter) in the diagnosis of coronary artery disease (CAD) in the elderly.Method 100 patients with suspected CAD undergoing both 12 lead Holter and coronary angiography were analyzed.Results The overall sensitivity, specificity, positive and negative predicted values and accuracy in detecting CAD with 12 lead Holters were 63.8%, 79.2%, 73.2%, 71.2% and 72%, respectively. The sensitivity was 100% in identifying triple vessel and left main coronary artery (LMCA) stenosis, whereas the sensitivity in detecting LAD, LCX and RCA stenosis (65.8%,70.6% and 75%, respectively) was not significantly different.Conclusion 12 lead Holter does not have a high level sensitivity and specificity in detecting CAD in the elderly ,but the sensitivity in diagnosing triple vessel disease and LMCA stenosis is high. 12 lead Holter has some value in clinical application.
