摘  要:目的运用循证医学(EBM)理论,研究和评价有关肌红蛋白(Mb)和肌钙蛋白(cTn)对急性心肌梗死(AMI)诊断的文献,探讨Mb和cTn对AMI诊断的价值。方法按照EBM标准,对1994-2005年间《中国学术期刊检索数据库》、《中国生物医学期刊数据库》、《外文生物医学期刊文献数据库》中以Mb、肌钙蛋白I(cTnI)或肌钙蛋白T(cTnT)作为检测指标诊断AMI的全部文献(包括论文、综述、摘要)进行回顾性检索并作出评价。结果1994-2005年间共检索到目标文献中文93篇,英文30篇,多数文献设有临床对照试验(中文占94.5%,英文占53.3%)、盲法研究(中文占19.8%,英文占10.0%)及随机对照组(中文占9.9%,英文占16.7%);42篇文章未提供基线资料。结论通过分析、研究和评价目前国内外应用Mb和cTn对AMI诊断的文献,表明Mb和cTnI联合检测能体现最佳的灵敏度和特异性,对AMI的早期诊断具有非常重要的临床意义。Objective To explore the diagnostic value of serum myoglobin (Mb) and cardiac troponin (cTn) in patients with acute myocardial infarction (AMI) by reviewing and evaluating the corresponding references with evidence-based medicine (EBM) theory. Methods All references (including papers,reviews and abstracts) of CNKI-CHKD,CMCC(1994-2005)and EMCC(1995-2005) were collected and retrospectively analyzed according to evidence based medicine (EBM) standard, with Mb cTn as the detected indices for diagnosing AMI. Results In the searched period of 1994-2005,123 papers were published (93 pieces were written in Chinese,and 30 were written in English). In most references, the authors set clinical control trial (CCT) (Chinese : 92.5 % ; English : 53.3 % ), blind control trial (Chinese: 19.4%; English: 10.0%)and/or random control trial (RCT) (Chinese: 9.7%; English: 16.7%). The respective reference ranges weren't provided in 42 pieces of articles. Conclusion The analytic result of the references in home and aborad indicates combined detection of Mb and cTnI posseses favourite sensitivity and specificity,which contributes to the early diagnosis of acute myocardial infarction.
