目的探讨室上性心动过速缺血型ST段下移对冠心病(CAD)的诊断价值。方法对武汉大学人民医院1992—2008年收治的在室上性心动过速发作时出现ST段下移并行冠状动脉造影者,收集其临床资料及冠状动脉检查结果进行分析。结果共纳入65例患者,分为两组:A组在心动过速发作时伴缺血型ST段下移,B组伴非缺血型ST段下移,并依据年龄将A组分成几个亚组,分别比较各组CAD诊断率。A组48例中有23例(47.92%)有CAD,B组17例中无一例有CAD,A组诊断价值显著高于B组(P<0.05),且年龄越大,诊断价值越高。结论室上性心动过速缺血型ST段下移对CAD有一定诊断价值,且随年龄增长,诊断价值进一步增大。
Objective To investigate the diagnostic value of ST-segment elevation of supraventricular tachycardia in patients with coronary heart disease (CAD). Methods From 1992 to 2008, Wuhan University People’s Hospital admitted patients with ST-segment downgoing parallel coronary angiography who had episodes of supraventricular tachycardia. The clinical data and the results of coronary artery examinations were collected for analysis. Results A total of 65 patients were enrolled and divided into two groups: group A with tachycardia with ST-segment elevation and group B with non-ischemic ST-segment elevation with group A divided into several groups according to age Subgroups, respectively, compared the diagnosis rate of CAD in each group. Among the 48 cases in group A, 23 cases (47.92%) had CAD, and none of 17 cases in group B had CAD. The diagnostic value of group A was significantly higher than that in group B (P <0.05), and the higher the age, the higher the diagnostic value. Conclusion ST-segment elevation of supraventricular tachycardia is of diagnostic value to CAD, and with age, the value of diagnosis is further increased.
