BACKGROUND: Neutrophils and albumin had been shown to be independent predictors of mortality from various diseases. Purpose of this study was to investigate the effect of neutrophil-to-albumin ratio (NPAR) as an independent predictor of mortality in heart failure (HF) patients.

METHODS: Data were extracted from Medical Information Mart for Intensive Care-III database. Primary outcome was 30-day mortality, secondary outcomes were in-hospital, 90-day, 365-day mortality, length of stay (LOS) in hospital. Cox proportional hazards regression model and receiver operating characteristic (ROC) curve analysis and Pearson correlation analysis were used.

RESULTS: The HR (95% CI) values of the mid-tertile and the upper tertile were 1.27 (1.01 to 1.59) and 2.29 (1.87 to 2.81) in 30-day mortality compared with the reference. The trend continued after adjusted for demographic and clinical variables. In the secondary outcomes were the same trends. The data of the Second Affiliated Hospital of Wenzhou Medical University showed the correlation coefficient between hospital LOS with NPAR.

CONCLUSION: NPAR was an independent factor of mortality in HF patients, which was correlated with hospital LOS. Our results need to be verified by prospective studies.
