RESUMEN
Objective: To explore the application value on combined examination of blood levels of growth differentiation factor-15 (GDF-15) and NT-pro B-type natriuretic peptide (NT-proBNP) in patients after successful cardiopulmonary resuscitation (CPR) for their recent prognosis. Methods: A total of 102 patients with sudden cardiac arrest and successful CPR in our hospital were enrolled. Blood levels of GDF-15 were examined at immediately, 12 h and 24-48 h after CPR respectively. According to GDF-15 levels, the patients were divided into 3 groups: Group A, the patients with GDF-151200 ng/L at all-time points,n=35; Group C, GDF-15 level consistently increasing at 12 h and 24-48 h after CPR, while it was lower at 24-48 h than 12 h after CPR,n=36. Blood levels of NT-proBNP and left ventricular ejection fraction (LVEF) were also examined. The patients were followed-up for 6 months for post-CPR death. Results: Blood levels of GDF-15 and NT-proBNP were related, NT-proBNP level was changing with GDF-15 varying. GDF-15 and NT-proBNP level was negatively related to LVEF (r=-0.530,P1800 ng/L and NT-proBNP>400 pg/ml had the higher mortality than those had the lower levels of GDF-15 and NT-proBNP,P0.05. Conclusion: Combined examination for blood levels of GDF-15 and NT-proBNP may better predict the recent prognosis in patients who received CPR.
