Abstract:
Objective To evaluate the value of human fatty acid binding protein (h-FABP) in predicting myocardial ischemia and injury in the perioperative period of cardiac surgery, we observed the dynamic changes of h-FABP in perioperative period of patients underwent coronary artery bypass grafting and ventricular septal defects repairing surgery, and evaluated the relationship of h-FABP and ischemia modified albumin ( IMA), CK-MB, cTnI. Methods Patients underwent coronary artery bypass grafting (n =30) and ventrieular septal defect repairing (n = 30) surgery between February 2008 and December 2008 were included in this study. Venous blood sample was obtained at preoperative, aortic clamping, aortic unclamping of 10 rain, 2 h, 6 h, 12 h, 24 h for the measurements of h-FABP, IMA, cTnI and CKMB. Results h-FABP and IMA changed in the same way at various examined time points, h-FABP changes also paralleled cTnI and CK-MB changes, h-FABP peaked early during myocardial ischemia and injury and returned to baseline level at 2 h post myocardial ischemia and injury. Linear correlation analysis showed that the peak value of h-FABP was positively correlated with IMA, CK-MB and cTnI in both CABG group (r =0. 948, 0. 964 and 0. 961, P < 0. 05 ) and in the VSD group ( r = 0. 986, 0. 978 and 0. 957). Conclusions h-FABP is an early diagnostic parameter reflecting perioperative myocardial ischemia and injury in cardiac surgery. Quantitative h-FABP monitoring could predict the severity of myocardial ischemia and injury early during cardiac surgery.
