老年冠心病诊断中无创性诊断方法的评价

Evaluation of 4 noninvasive methods in the diagnosis of coronary heart disease

本文在８０例老年人中以冠状动脉造影结果为标准，评价了静息１２导联心电图（ＥＣＧ）、２４小时动态心电图（Ｈｏｌｔｅｒ）、二维超声心动图（ＵＣＧ）及心肌核素显像平衡法（ＥＭ）在老年冠心病诊断中的价值。结果显示，上述方法的诊断敏感性、特异性、阳性预测值及诊断指数分别是：ＥＭ为９１．２％、８８．９％、９６．９％、８０．１％；ＥＣＧ为９１．５％、４４．４％、９２．９％、３５．９％；ＵＣＧ为４８．３％、７７．８％、９３．５％、２５．８％；Ｈｏｌｔｅｒ为６６．７％、１６．７％、８１．５％、１６．６％。４种无创性静息检查方法中，ＥＭ诊断指数最高，其次为ＥＣＧ。

The values of rest ECG ,Holter , UCG and EM were analyzed according to the results of angiography .in the diagnosis of coronary heart disease in 80 elderly cases. The results showed that the sensitivity ,specificity .positive predictive value and diagnostic index of these four methods were 91. 2%, 88. 9%, 96. 9% and 80. 1 % for EM, respectively , 91. 5% , 44. 4% ,92. 9% and 35. 9% for ECG, respectively,48. 3% , 77. 8% , 93.5% and 25. 8% for UCG ,respectively, and 66. 7% , 16. 7% , 81. 5% and 16. 6% for Holter , respectively. In summary ,the diagnostic index of EM methods was the highest among these four methods.
