女性绝经前后运动平板试验假阳性率的对比研究

目的 分析在胸痛患者中运动平板试验阳性对冠心病的诊断符合率.比较男性、女性绝经前、绝经后运动平板试验假阳性率的差异.方法 268例胸痛运动平板试验阳性患者,行冠状动脉造影检查,冠状动脉狭窄超过50%诊断为冠心病.结果 268例患者冠状动脉造影检查诊断为冠心病176例(65.67%),女性绝经前患者假阳性率为66.67%(26/39),明显高于男性患者(28.08%,41/146)和女性绝经后患者(30.12%,25/83)(P < 0.01),女性绝经后患者与男性患者假阳性率比较差异无统计学意义(P > 0.05).结论 胸痛患者在冠状动脉造影前行运动平板试验筛查,阳性者再行冠状动脉造影检查可大大提高冠状动脉造影检查的阳性率.女性绝经前患者运动平板试验假阳性率较男性患者和女性绝经后患者高.

Comparative study of woman false positive rate in exercise treadmill before or after menopause

Objective To analyse the rate of coincidence to suspected coronary artery disease (CAD) patient between positive exercise treadmill testing (TET) and coronary angiography (CAG) test.Method Two hundred and sixty-eight chest pain patients positive in TET were performed CAG test,coronary stenosis exceed 50% was diagnosed CAD. Results One hundred and seventy-six patients (65.67%) was diagnosed by CAG, 105 male and 71 female in them. Ninety-two (34.33%) patients was negative in CAG test. The false positive rate of TET between post-menopause patients (30.12%, 25/83 ) andmale patients (28.08%, 41/146) was no significant difference(P > 0.05 ); the difference of false positive rate between pro-menopause patients (66.67%, 26/39) and male patients (28.08% ,41/146) was statistical significance (P < 0.01 ). Conclusions The positive rate of CAG can be greatly improved by screening the chest pain patients though TET before CAG, if the positive in TET performed CAG only. TET false positive rate of pro-menopause female is significantly higher than post-menopause female or male.
