H-FABP is a sensitive biomarker for myocardial infarction [7, 25, 26] and one study showed increased sensitivity of 20.6% over troponin at 3–6 hours following chest pain onset [27] similar to our study, where in H-FABP had higher sensitivity of 58% (95% CI 37.4–74.5) when compared with cTnI 40% (95% CI 23–59) and cTnT 47% (95% CI 28–66). The gene discussed is TNNI3; the disease is myocardial infarction.
