Prognostic value of the cardiac fraction of fatty acid binding protein in patients with non-ST elevation acute coronary syndrome with concomitant type 2 diabetes

Aim. To study the association between a positive results of Heart-type fatty acid binding protein (h-FABP) test with the development of adverse outcomes during the year of observation in patients with non-ST elevation acute coronary syndrome (NSTE-ACS) depending on the type 2 diabetes mellitus (DM-2) presence. Material and methods. The study included 153 patients with NSTEACS hospitalized in the department of emergency cardiology in the period from March 2014 to January 2017. In addition to the standard examination, all patients underwent a qualitative analysis on the h-FABP in venous blood. Results. Kaplan–Meier estimator demonstrated a significant probability of a combined end point in patients with positive h-FABP, both with and without DM-2. H-FABP also acts as a marker for the development of adverse outcomes during the year after NSTE-ACS. Patients with adverse outcomes and type 2 diabetes mellitus had the highest frequency (100%) of positive test reactions. Conclusion. H-FABP positive test when admitted to hospital may be considered as a predictor of adverse long-term outcomes in patients with NSTE-ACS. That statistics is most significant for patients with DM-2.
