AbstractHeart failure is a clinical syndrome. In this study, the significance of the blood urea nitrogen-to-left ventricular ejection fraction (BUNLVEF) ratio in predicting short-term mortality in patients with heart failure symptoms was evaluated. This retrospectively designed study was conducted by evaluating the records of patients with a history of heart failure who presented to the emergency department with heart failure symptoms and signs from 01 January 2018 to 01 January 2020. One hundred and seventy-three patients were included in the sample within the last six months presented to the emergency department with the symptoms of acute heart failure. Blood urea nitrogen (BUN) and the BUNLVEF ratio had a significant relationship with mortality (p=0.004 and <0.010, respectively). In patients with a known history of heart failure presenting to the emergency department with heart failure symptoms, it would be more appropriate to evaluate poor outcomes with the BUNLVEF ratio rather than the LVEF or BUN value alone. Key Words: Blood urea nitrogen, Prognosis, Left ventricular dysfunction.
