Abstract: Objective To explore the value of heart-type fatty acid-binding protein (H-FABP) in the early diagnosis of acute myocardial infarction (AMI). Methods Sixty confirmed AMI patients were observed, the data of H-FABP, cardiac troponin T (cTnT), creatine kinase MB (CK-MB) were detected in < 6 h and 6-12 h after the symptoms appeared, and the sensitivity of the three markers was calculated. The specificity was compared with 15 uncertain AMI patients and 45 healthy subjects. Results The early diagnosis sensitivity of H-FABP in < 6 h was 94% in AMI, which was higher than that of cTnT (50%) and CK-MB (56%) (P < 0.05 ). The diagnosis sensitivity of H-FABP, CTnT, CK-MB in 6-12 h was 100%, 92%, 92% respectively (P> 0.05 ). There was no significant difference in the specificity among the three markers (P > 0.05). Conclusions H-FABP has more sensitivity and specificity in the early diagnosis of AMI. It is applicable in the screening of patients who suffered chest pain and the diagnosis of early AMI.
