Abstract:
Objective To evaluate the diagnostic value of H-FABP for early detection of acute myocardial infarction(AMI). Methods Serum H-FABP of 126 healthy individuals and 53 AMI patients were measured by self developed ELISA. MYO, cTnI and CK-MB, traditional biochemistry diagnostic markers were estimated at the same time. The dynamic movement of these myocardial indicators for AMI patients, and their diagnostic sensitivity and specificity in the earlier period of AMI onset was analyzed. Results The plasma concentration of H-FABP began to increase at (1.84?0.64) h after AMI onset, earlier than CK-MB and cTnI. The time-concentration dynamic curves of H-FABP was similar to that of MYO and moved to left in comparison with both CK-MB and cTnI. The sensitivity and specificity of H-FABP at 2 h after AMI were 76.47% and 80.41%, and 89.16% and 91.26% at 4 h, respectively;. Conclusions H-FABP is more sensitive and specific in the early diagnosis of AMI within 2 hours and at 4 hours after symptom onset. It is hoped that H-FABP become an important myocardial marker for both early diagnosis and elimination diagnosis of AMI.
