摘要
目的探讨心脏型脂肪酸结合蛋白(H—FABP)在临床诊断早期急性非sT段抬高心肌梗死(NSTEMI)中的优势及应用价值。方法疑似NSTEMI患者118例,按发病后就诊时间分为两组,分别在发病后0-3h、3-6h内检测H—FABP,同时检测肌钙蛋白I(cTnI)、肌酸激酶同功酶(CK—MB)及肌红蛋白(MYO)进行对比,计算各项指标的灵敏度、特异性、准确性、阳性预测值及阴性预测值并进行比较分析。结果H—FABP在发病0-3h内诊断NSTEMI的灵敏度为66.7%,高于cTnI及CK—MB,差异有统计学意义(P〈0.05);特异性为88.9%;准确性为78.4%。在发病3-6h内诊断NSTEMI的灵敏度为94.4%,高于cTnI及cK—MB,差异有统计学意3L(P〈0.05),特异性87.1%,准确性为91.0%。结论H—FABP是诊断早期(发病6h以内)NSTEMI的敏感指标,在急性冠脉综合征早期的危险分层中有重要的临床应用价值。
Objective To study and master the advantage and its applicable value of Heart-type fatty acid-binding protein (H-FABP) in diagnosing the early stage Non-ST elevated myocardial infarction (NSTEMI). Methods H-FABP, cTnl, CK-MB and myoglobin were detected synchronously within 3 hours and 6 hours at 118 cases of suspected NSTEAMI. The data of sensitivity, specificity, accuracy, positive predictive value and negative predictive value was obtained and calculated. Results The sensitivity of H-FABP within 3 hours was 66.7%, higher than that of cTnI and CK-MB (P〈0. 05); the specificity was 88.9%, and the accuracy was 78.4%. The sensitivity of H-FABP within 3 hours was 94.4%, also higher than that of cTnI and CK-MB (P〈0.05); the specificity was 87.1%, and the accuracy was 91.0%. Conclusion H-FABP, the most sensitive indicator of early NSTEAMI (within 6 hours) diagnosis, reflected critical clinical value for the risk stratification of acute coronary syndrome.
