摘要
【目的】研究不稳定型心绞痛(UA)患者肌钙蛋白(TnT)与冠状动脉病变及预后的关系。【方法】 98例UA患者根据TnT是否阳性分成TnT阳性组(36例),TnT阴性组(62例),于住院期间行冠状动脉造 影(CAG)并观察其心脏事件的发生情况,对比分析两组UA患者的冠状动脉造影特点及预后。【结果】TnT 阳性组冠状动脉造影阳性率为94.5%,三支病变发生率41.7%,左主干病变19.4%,冠脉内血栓形成者为 22.2%,均明显高于TnT阴性组;TnT阳性组近期(30d)心脏事件发生率30.5%,亦明显高于TnT阴性组, 且两组相比差异均有显著性(P<0.01)。【结论】TnT阳性的UA患者复杂病变多及冠脉内血栓形成率高且 预后较差。
ObjectiveTo evaluate relations among Troponin T (TnT), coronary lesion and prognosis in unstable angina (UA) patients.Ninety-eight patients with UA were classified into two groups according to whether serum levels of TnT were positive(group 1,n=36) or negative (group 2,n=62).Coronary angiogram(CAG) in UA patients was done in the hospital and the development of cardiac events observed. Through contrast, the CAG and prognosis in TnT positive patients were analysed.There was 94.5% of positive rate of CAG:41.7% of three branches lesion, 19.4% of the main left branch lesion and 22.2% of coronary thrombosis in TnT positive patients,which was higher than in TnT negative patients(P< 0.01).Cardiac attacking events rates were 30.5% at recent 30 days in TnT positive patients,also higher than in negative patients(P<0.01).[Conclusion]There are more complicated lesions,higher rate of coronary thrombosis and worse prognosis in TnT positive patients.
