Venous blood was withdrawn from consecutive patients with acute chest pain admitted to the First Affiliated Hospital of Xinjiang Medical University. The blood samples were used for measurement of creatine kinase MB (CK-MB) and cardiac troponin I (cTnI) using Beckman Coulter DC-800 analyzer, and detection of H-FABP using a one-step bedside immunotest.
Two hundred and eighty-nine patients admitted within 12 h after the onset of symptoms were recruited in the study. The H-FABP immunotest was found to have higher diagnostic accuracy than cTnI and CK-MB in patients admitted within 3 h. The combination of H-FABP and cTnI was found to have the highest diagnostic accuracy (91 % ) among different cardiac markers and the other combinations. It gave the highest sensitivity [96 % (95 % CI: 91–98 % )] and a comparable specificity [84 % (95 % CI: 76–89 % )] to cTnI alone.
A cardiac panel consisting of H-FABP and troponin is recommended.
