One-year mortality after hospitalization for acute heart failure: Predicting factors (PRECIC study subanalysis)

Abstract

Introduction and objectivesOne-year mortality after hospitalization for heart failure (HF) is high. This study aims to identify predictive factors of one-year mortality. MethodsThis is a retrospective, single-center and observational study. All patients hospitalized for acute HF during one year were enrolled. ResultsA total of 429 patients were enrolled, mean age of 79 years. The in-hospital and one-year all-cause mortality rates were 7.9% and 34.3%, respectively. In the univariable analysis, the factors significantly associated with higher one-year mortality risk were: age ≥80 years (odds ratio (OR)=2.05, 95% confidence interval (CI) 1.35–3.11, p=0.001); active cancer (OR=2.93, 95% CI 1.36–6.32, p=0.008); dementia (OR=2.84, 95% CI 1.81–4.47, p<0.001); functional dependency (OR=2.63, 95% CI 1.65–4.19, p<0.001); atrial fibrillation (OR=1.86, 95% CI 1.24–2.80, p=0.004); higher creatinine (OR=2.03, 95% CI 1.29–3.21, p=0.002), urea (OR=2.92, 95% CI 1.95–4.36, p<0.001) and red cell distribution width (RDW; 4thQ OR=5.59, 95% CI 3.03–10.32, p=0.001); and lower hematocrit (OR=0.94, 95% CI 0.91–0.97, p<0.001), hemoglobin (OR=0.83, 95% CI 0.75–0.92, p<0.001) and platelet distribution width (PDW; OR=0.89, 95% CI 0.82–0.97, p=0.005). In the multivariable analysis, the independent predictors of higher one-year mortality risk were: age ≥80 years (OR=2.05, 95% CI 1.21–3.48); active cancer (OR=2.70, 95% CI 1.03–7.01); dementia (OR=2.69, 95% CI 1.53–4.74); higher urea (OR=2.97, 95% CI 1.84–4.80) and RDW (4thQ OR=5.24, 95% CI 2.55–10.76); and lower PDW (OR=0.88, 95% CI 0.80–0.97). ConclusionsActive cancer, dementia, and high values for urea and RDW at admission are predictors of one-year mortality in patients hospitalized for HF. These variables are readily available at admission and can support the clinical management of HF patients.
