Admission levels of NT-proBNP were also significantly higher in non-survivors as compared to survivors in a study by Smit et al. 2015 (30), although not predictive of 28 day-mortality, but that study included all-comers with a cardiac arrest, and patients with a non-shockable rhythm might have cancelled the prognostic utility of NT-proBNP. The gene discussed is NPPB; the disease is cardiac arrest.
