摘　　要：目的探讨TIMI危险评分在急诊就诊的急性胸痛患者中鉴别非ST段抬高急性冠状动脉综合征(NSTE-ACS)的诊断价值。方法回顾性分析52例就诊于四川大学华西医院急诊科的急性胸痛患者。按TIMI危险评分的7个变量进行计分,以冠状动脉CT血管成像检查或(及)冠状动脉造影作为确诊标准,应用受试者工作特征(ROC)曲线以及Youden指数评价TIMI危险评分在急性胸痛患者中NSTE-ACS的诊断价值。结果 TIMI危险评分≥4分对于急性胸痛患者的NSTE-ACS有诊断价值。结论 TIMI危险评分增高的急性胸痛患者对于急性胸痛患者的NSTEACS有较好的诊断意义。Objective To evaluate the significance of TIMI risk scores in diagnosis of NSTE-ACS by ROC curve analysis. Methods 52 patients with acute chest pain were analyzed retrospectively. TIMI risk scores were measured. And All of these patients were given coronary CT angiography or/and invasive coronary anglography to detect the lesions in coronary artery. TIMI sores, coronary CT angiography and invasive coronary angiography were analyzed by ROC curve and Youden index. Results The possible reason in the patient with acute chest pain, whose TIMI risk scores is more than 4, is NSTE-ACS. Conclusion TIMI risk scores can be used in patients with acute chest pain to diagnose NSTE-ACS.
