目的:探讨联合检测和肽素(Copeptin)、高敏心肌肌钙蛋白T( hs-cTnT)对急性心肌梗死( AMI)的早期诊断价值。方法:选取272例因胸痛4小时内就诊的患者,入院后均行冠状动脉造影术(CAG)。其中排除冠心病患者64例(CAG正常组),不稳定性心绞痛患者50例(UAP组),ST段抬高型心肌梗死(STEMI)患者82例(STEMI组),非ST段抬高型心肌梗死(NSTEMI)患者76例(NSTEMI组)。入选患者均留院观察,抽取就诊时及胸痛6小时后肘静脉血,检测和肽素、hs-cTnT水平。结果:胸痛4小时内就诊时联合检测和肽素、hs-cTnT在诊断AMI上相比单独检测hs-cTnT具有更高的灵敏度(以hs-cTnT≤14ng/L、和肽素<14pmol/L为诊断切点)。NSTEMI组:AUC为0.97[95%可信区间(CI):0.88~0.99]:AUC为0.75(95%CI:0.62~0.87),P<0.05。STEMI组:AUC为0.97(95%CI:0.88~0.99): AUC为0.74(95%CI:0.60~0.88), P<0.05。联合检测和肽素、hs-cTnT的AUC为0.912(95%CI:0.812~0.961),高于单独检测hs-cTnT(AUC为0.851,95%CI:0.713~0.936)早期诊断AMI的效能(Z=2.553,P<0.05)。结论:联合检测和肽素、hs-cTnT与单独检测hs-cTnT相比,对于早期诊断急性心肌梗死有更高的灵敏度、准确性,有助于胸痛患者早期危险分层,对治疗决策具有临床价值。
目的:探討聯閤檢測和肽素(Copeptin)、高敏心肌肌鈣蛋白T( hs-cTnT)對急性心肌梗死( AMI)的早期診斷價值。方法:選取272例因胸痛4小時內就診的患者,入院後均行冠狀動脈造影術(CAG)。其中排除冠心病患者64例(CAG正常組),不穩定性心絞痛患者50例(UAP組),ST段抬高型心肌梗死(STEMI)患者82例(STEMI組),非ST段抬高型心肌梗死(NSTEMI)患者76例(NSTEMI組)。入選患者均留院觀察,抽取就診時及胸痛6小時後肘靜脈血,檢測和肽素、hs-cTnT水平。結果:胸痛4小時內就診時聯閤檢測和肽素、hs-cTnT在診斷AMI上相比單獨檢測hs-cTnT具有更高的靈敏度(以hs-cTnT≤14ng/L、和肽素<14pmol/L為診斷切點)。NSTEMI組:AUC為0.97[95%可信區間(CI):0.88~0.99]:AUC為0.75(95%CI:0.62~0.87),P<0.05。STEMI組:AUC為0.97(95%CI:0.88~0.99): AUC為0.74(95%CI:0.60~0.88), P<0.05。聯閤檢測和肽素、hs-cTnT的AUC為0.912(95%CI:0.812~0.961),高于單獨檢測hs-cTnT(AUC為0.851,95%CI:0.713~0.936)早期診斷AMI的效能(Z=2.553,P<0.05)。結論:聯閤檢測和肽素、hs-cTnT與單獨檢測hs-cTnT相比,對于早期診斷急性心肌梗死有更高的靈敏度、準確性,有助于胸痛患者早期危險分層,對治療決策具有臨床價值。

Objective: To investigate the diagnostic value of combined examination of copeptin and high sensitivity cardiac troponin T (hs-cTnT) in patients at the early stage of acute myocardial infarction (AMI) . Methods: A total of 272 patients were enrolled in this study, all of them suffered from chest pain and admitted within 4 hours. The patients were divided into 4 groups according to coronary artery angiography (CAG) results. Control group, the patients with normal CAG,n=64, UAP group (unstable angina pectoris),n=50, STEMI group,n=82, NSTEMI group,n=76. All patients received in-hospital observation, plasma levels of copeptin and hs-cTnT were examined at admission and at 6 hours after the chest pain respectively. Results: Within 4 hours of chest pain, combined examination of copeptin and hs-cTnT had the higher sensitivity for diagnosing AMI than a single detection of hs-cTnT with the cut-off point of hs-cTnT ≤ 14ng/L and Copeptin < 14pmol/L. In NSTEMI group, the AUC (area under curve) for combined examination was 0.97 (95% CI 0.88-0.99), AUC for single hs-cTnT detection was 0.75 (95% CI 0.62-0.87),P<0.05. In STEMI group, the AUC for combined examination was 0.97 (95% CI 0.88-0.99), AUC for single hs-cTnT detection was 0.74 (95% CI 0.60-0.88),P< 0.05. The AUC for combined examination of copeptin and hs-cTnT in diagnosing early AMI was 0.912 (95% CI 0.812-0.961) which was higher than single detection of hs-cTnT, AUC 0.851 (95% CI 0.713-0.936), Z=2.553,P<0.05. Conclusion: Combined examination of copeptin and hs-cTnT had the higher sensitivity and accuracy for diagnosing the patients at the early stage of AMI, it may help the risk stratiifcation of chest pain which is valuable in clinical practice.
