复合试验在糖尿病合并冠心病中的应用

D O test in diabetes mellitus with coronary heart disease

目的：探讨潘生丁食管心房调搏试验（ 简称复合试验） 对糖尿病合并冠心病的诊断价值。方法：对糖尿病合并冠心病３２ 例、单纯糖尿病３４ 例和健康人３１ 名，行复合试验、食管心房调搏试验和潘生丁试验。结果：复合试验、食管心房调搏试验和潘生丁试验对糖尿病合并冠心病的诊断阳性率分别为８１ ．３ ％ 、６８ ．８ ％ 和５６ ．３ ％ 。复合试验与潘生丁试验差异有显著性（ Ｐ＜ ０ ．０５） ，但与食管心房调搏试验差异无显著性（ Ｐ＞ ０ ．０５） 。在假阳性方面，三种方法差异均无显著性（ Ｐ＞ ０ ．０５） 。结论：复合试验可作为糖尿病合并冠心病辅助诊断方法之一。

Objective:To study the role of dipyridamole esophagus atrium frequency modulation test(D O test)in dignosis of diabetes mellitus with coronary heart disease.Methods:D O test,esophagus atrium frequency modulation test and dipyridamole test were performed in 32 cases of diabetes mellitus(DM) patients with coronary heart disease(CHD),34 cases of DM and 31 healthy persons.Results:Positive rate in the three tests were 81.3%,68.8% and 56.3%, respectively.Positive rate in D O test was significantly higher than that in dipyridamole test( P <0.05),but its difference to the esophagus atium frequency modulation test is not significant( P >0.05),and the false positive rate among these three tests were also not significant( P >0.05).Conclusions:D O test can be an auxiliary method in diagnosis DM with CHD.
