Abstract
ObjectiveHeart-type fatty acid binding protein (H-FABP) is a tissue-specific protein which is rapidly released into the circulation when cardiomyocyte injury occurs. The aim of the study is to investigate the prognostic relevance of H-FABP for out-of-hospital cardiac arrest (OHCA) patients in the early post-cardiac arrest period. Design and methodsThis is a prospective cohort study enrolling non-traumatic resuscitated OHCA patients. ResultsA total of 106 patients were enrolled. The H-FABP level at 24h was correlated to the duration from collapse to return of spontaneous circulation (p<0.001, R2=0.549). The outcomes of survival to discharge were worse in the patient group with the higher tertile of plasma H-FABP level at 24h after the event (p=0.011). Multivariate analysis demonstrated that the significant predictors for in-hospital mortality were APACHE II score (p=0.010), gender (p=0.025) and the tertiles of H-FABP at 24h with hazard ratios for the lowest, middle, and highest tertiles being 1.0, 1.157 (95% confidence interval 0.435–3.075, p=0.770), and 2.840 (95% confidence interval 1.137–7.092, p=0.025), respectively. ConclusionThe plasma level of H-FABP at 24h after the event may be an early and independent factor associated with survival to discharge in OHCA patients.
