Summary	Serum albumin and renal function play an important role in maintaining physiological homeostasis. The aim of this study is to evaluate the association between blood urea nitrogen to albumin (B/A) ratio before cardiac resynchronization therapy (CRT) implantation and mortality. We studied 391 patients who implanted CRT between 2002 to 2014. During 32 months of follow-up, 117 (30%) patients died from any cause. There was a significantly higher B/A ratio in dead patients than survived (p<0.05). 63% of CRT patients had decreased left ventricular end-systolic volume (LVESV) more than 15% after 6 months of CRT (responders). By cox regression analysis, independent risks for mortality were non-responder and high value of B/A ratio (Table). Our results suggested that B/A ratio is an independent predictor of mortality in HF patients treated by CRT.
