The sensitivity, specificity, positive predictive and negative predictive values of H-FABP and hs of troponin T in the duration of 0 - 3 hours, were 89.3%, 82.1%, 93.7%, 69.7% and 53.3%, 89.3%, 84.3%, 64.1% respectively; in the duration of 3 - 6 hours were 91.7%, 83.3%, 83.3%, 88.5% and 83.3%, 91.7%, 90.6%, 84.6% respectively; so in the duration of 0 - 6 hours, the H-FABP sensitivity was higher than that of hs troponin T; If combining H-FABP and hs troponin T, the sensitivity would increase at all time, Specifically, within 0 - 3 hours, 3 - 6 hours, 3 - 12 hours, 12 - 24 hours, and > 36 hours the sensitive was 92.9%, 95.8%, 94.7%, 96.2%, 90.6%, 85.7% respectively.
