目的:比较HEART、TIMI及GRACE评分对急性非ST段抬高型心肌梗死(non-ST-segment elevation myocardial infarction,NSTEMI)患者发病后7 d、28 d主要不良心血管事件(major adverse cardiovascular events,MACEs)的预测价值。方法:回顾性收集2017年10月至2018年10月就诊于复旦大学附属中山医院急诊科胸痛患者中的心源性胸痛患者566例,排除ST段抬高型心肌梗死(ST-segment elevation myocardial infarction,STEMI)患者105例及失访患者15例,最终纳入109例NSTEMI患者及337例非心梗心源性胸痛患者,将NSTEMI患者按照是否发生MACEs分亚组,采用LSD-n t检验、Mann-Whitney n U检验或n χ2检验分析比较就诊时的基线资料,临床数据,HEART、TIMI及GRACE评分在两亚组之间的差异;多因素Logistic回归分析发病后7 d、28 d发生MACEs的独立因素;并通过受试者工作曲线(ROC曲线)比较不同评分对NSTEMI患者7 d MACEs和28 d MACEs的预测价值。n 结果:NSTEMI组和非心梗心源性胸痛患者组相比,性别、冠心病既往史、罹患3个及以上动脉粥样硬化危险因素、心电图、高敏肌钙蛋白T值(high-sensitivity troponin T,hs-cTnT)、肌酐值、心梗既往史、HEART评分、TIMI评分和GRACE评分差异有统计学意义(均n P<0.05)。进一步将NSTEMI患者按照是否发生MACEs进行亚组分析和多因素分析,发现卒中既往史、hs-cTnT升高是NSTEMI患者发病后7 d发生MACEs的独立因素。而卒中既往史、TIMI评分是NSTEMI患者发病后28 d发生MACEs的独立因素。ROC曲线比较不同评分对NSTEMI患者发生MACEs预测价值显示,TIMI评分的预测价值(AUC=0.715,95%n CI:0.482~0.948)优于HEART评分(AUC=0.659,95%n CI:0.414~0.904)及GRACE评分(AUC=0.587,95%n CI:0.341~0.833)。n 结论:HEART评分、TIMI评分和GRACE评分可用于NSTEMI患者的评估。TIMI评分对NSTEMI患者发生MACEs预测价值优于HEART及GRACE评分,并且对28 d MACEs的发生有独立预测价值。“,”Objective:To compare the predictive value of the HEART, TIMI and GRACE scores for major adversecardiovascular events (MACEs) at 7 and 28 days in patients with actue non-ST-segment elevation myocardial infarction (NSTEMI).Methods:More than 12 000 patients with chest pain from the Emergency Department of Zhongshan Hospital Affiliated to Fudan University from October 2017 to October 2018 were studied, including 566 patients with cardiogenic chest pain, 105 patients with ST-segment elevation myocardial infarction (STEMI) excluded and 15 patients lost to follow-up. Finally, 109 patients with NSTEMI and 337 non-myocardial patients with cardiogenic chest pain were enrolled. NSTEMI patients were divided into subgroups according to whether MACEs occurred. LSD n t-test, Mann-Whitney n U test or n χ2 test were used to analyze and compare the differences between the two subgroups about the baseline data, clinical data, HEART, TIMI and GRACE scores at the time of visit. Multivariate logistic regression analysis was used to explore the independent factors of MACEs at 7 and 28 days. And the predictive values of different scores for 7-day MACEs and 28-day MACEs were compared in NSTEMI patients through the receiver operating characteristic (ROC) curve.n Results:Compared NSTEMI patients with non-myocardial patients with cardiogenic chest pain, we found a statistically significant differences in sex, past history of coronary heart disease,≥3 risk factors for atherosclerosis, electrocardiogram, high-sensitivity troponin T (hs-cTnT), creatinine value, past history of myocardial infarction, HEART score, TIMI score and GRACE score. In further subgroup analysis of NSTEMI patients who were divided according to whether MACEs occurred, we found previous history of stroke and increased hs-cTnT were statistically different in 7 days after the onset of the disease. The multivariate analysis showed that the previous history of stroke and increased hs-cTnT were independent factors for the occurrence of MACEs at 7 days after the onset of NSTEMI; The previous history of stroke and increased hs-cTnT, electrocardiogram ST segment depression and TIMI score were statistically different at 28 days after the onset of NSTEMI. The multivariate analysis showed that the previous history of stroke and TIMI score were independent factors for the occurrence of MACEs at 28 days after the onset of NSTEMI patients. ROC curve indicated that the predictive value of TIMI score (AUC=0.715, 95%n CI: 0.482-0.948) was better than HEART (AUC=0.659, 95%n CI: 0.414-0.904) and GRACE scores (AUC=0.587, 95%n CI: 0.341-0.833)in predicting MACEs in NSTEMI patients.n Conclusions:HEART score, TIMI score and GRACE score can be used to evaluate NSTEMI patients. There is an independent predictive value on TIMI score for the occurrence of 28-day MACEs in NSTEMI patients.
