【摘要】：目的探讨急性心肌梗死、主动脉夹层患者急诊入院时血清D二聚体(DD)、C反应蛋白(CRP)、肌钙蛋白I(cTnI)水平及血压不对称情况的差异。方法回顾102例因6 h内急性胸(背)痛伴或不伴呼吸困难初次就诊患者的临床资料,其中72例最终诊断为急性心肌梗死(AMI组),30例最终诊断为主动脉夹层(AAD组)。入院后立即抽取静脉血,采用乳胶法检测血清DD,采用免疫散射比浊法检测CRP,采用化学发光法检测cTnI,测量两臂血压观察是否存在血压不对称(双臂收缩压差≥20 mm Hg)。比较两组血清DD、CRP水平及血清cTnI升高、血压不对称发生率。结果 AMI、AAD组患者血清DD水平分别为(362±141)、(1 608±546)μg/L,两组相比P0.05。AMI、AAD组患者血清CRP水平分别为(12.9±3.60)、(13.8±3.48)mg/L,两组差异无统计学意义。AMI组72例(100%)血清cTnI升高、1例(1.4%)血压不对称,AAD组4例(13.3%)血清cTnI升高、10例(33.3%)血压不对称,两组血清cTnI升高、血压不对称发生率相比P0.05。结论急性心肌梗死、主动脉夹层患者急诊入院时血清DD、cTnI和血压不对称情况存在差异。血清DD、cTnI可用于急诊鉴别诊断急性心肌梗死和主动脉夹层。
[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，
