摘要:
目的 比较复极离散指数(RDI)和缺血性ST-T改变对冠心病(CHD)的诊断价值。 方法 以选择性冠状动脉造影(CAG)为标准诊断法,以可疑CHD患者227例为研究对象,利用四格表法,计算真实性评价指标。结果 ①尤登指数(YI)最大值为0.49, 相应的RDI=0.40为截断点;②RDI和缺血性ST-T改变诊断CHD的灵敏度、特异度及准确度分别为 66.7%对68.3%(P＞0.05)、82.2%对47.5%(P＜0.01)及73.6%对59.0%(P＜0.01);③RDI和缺血性ST-T改变联合(系列)实验的灵敏度为64.4%,特异度为83.2%,准确度为72.7%. 结论 RDI诊断CHD灵敏度与缺血性ST-T改变接近,但特异度高. 两者联合应用可减少误诊。
Abstract:
Aim　Comparison studying the diagnostic value of coronary heart disease between repolarization dispersion index and ischemic ST-T change. Methods:Coronary arteriography(CAG) regarded as the standard of diagnostic CHD. 227 cases with suspected CHD was studied. And assessment index of validity was calculated by contingency table. Results:①As RDI is located at 0.40, Youden′s index (YI) equals 0.49. Because of it highest, YI=0.40 is as boundary value. ② Sensitivity and specificity and accuracy for observation of RDI and ischemic ST-T change was 66.7% vs 68.3%(P＞0.05),82.2% vs 47.5%(P＜0.01) and 73.6% vs 59.0%(P＜0.01) respectively. ③ Sensitivity and specificity and accuarcy for observation of RDI with ischemic ST-T change was 64.4%,83.2% and 72.7% respectively. Conclusion:RDI is similar to ischemic ST-T change on sensitivity of diagnostic CHD. But specificity of RDI is high. Their combination can decrease mistake diagnostic rate.
