Abstract:

AIM: To explore the value of three cardiac markers in the early diagnosis of acute myocardial infarction(AMI).  METHODS: 90 cases of AMI were selected as the experimental group, and were further divided into the (0-3 h) group (34 cases) and (3-6 h) group (56 cases) according to the on-set time. 80 cases of healthy check-ups were recruited in the control group, and another 20 cases of muscle injury were also selected in this experiment. High-sensitivity cardiac troponin I(hs-cTnI) ,heart fatty acid-binding protein (H-FABP) and myoglobin(MYO) were measured simultaneously. RESULTS:Serum concentrations of H-FABP, hs-cTnI and MYO in the 34 AMI patients of (0-3 h) group and 56 AMI patients level of the experimental group were higher than those of control group(P<0.01); serum concentrations of MYO in patients with muscle injury were higher than those of control group(P<0.01); the specificity and sensitivity of H-FABP and cTnI were higher than those of MYO within the early onset time of AMI (0-3 h, 3-6 h); hs-cTnI was more sensitive than cTnI in the early onset of AMI. CONCLUSION: H-FABP and hs-cTnI can be referential serum markers for early diagnosis of AMI.
