【摘要】：目的探討急性心肌梗死、主動脈夾層患者急診入院時血清D二聚體(DD)、C反應蛋白(CRP)、肌鈣蛋白I(cTnI)水平及血壓不對稱情況的差異。方法回顧102例因6 h內急性胸(背)痛伴或不伴呼吸困難初次就診患者的臨床資料,其中72例最終診斷為急性心肌梗死(AMI組),30例最終診斷為主動脈夾層(AAD組)。入院后立即抽取靜脈血,采用乳膠法檢測血清DD,采用免疫散射比濁法檢測CRP,采用化學發(fā)光法檢測cTnI,測量兩臂血壓觀察是否存在血壓不對稱(雙臂收縮壓差≥20 mm Hg)。比較兩組血清DD、CRP水平及血清cTnI升高、血壓不對稱發(fā)生率。結果 AMI、AAD組患者血清DD水平分別為(362±141)、(1 608±546)μg/L,兩組相比P0.05。AMI、AAD組患者血清CRP水平分別為(12.9±3.60)、(13.8±3.48)mg/L,兩組差異無統(tǒng)計學意義。AMI組72例(100%)血清cTnI升高、1例(1.4%)血壓不對稱,AAD組4例(13.3%)血清cTnI升高、10例(33.3%)血壓不對稱,兩組血清cTnI升高、血壓不對稱發(fā)生率相比P0.05。結論急性心肌梗死、主動脈夾層患者急診入院時血清DD、cTnI和血壓不對稱情況存在差異。血清DD、cTnI可用于急診鑒別診斷急性心肌梗死和主動脈夾層。
[Abstract]:Objective to investigate the difference of serum D-dimer (DD), C reactive protein (CRP),) troponin I (cTnI) and blood pressure asymmetry in patients with acute myocardial infarction and aortic dissection. Methods the clinical data of 102 patients with or without acute chest pain or dyspnea within 6 hours were reviewed. 72 patients were diagnosed as acute myocardial infarction (AMI) and 30 as aortic dissection (AAD). Immediately after admission, venous blood was drawn, serum DD, was detected by latex method, CRP, was detected by immunoturbidimetric method, and chemiluminescence was used to measure the blood pressure of both arms. The blood pressure was measured by chemiluminescence method. The blood pressure asymmetry was observed (double arm systolic pressure difference 鈮，
