Two-year outcome of patients after a first hospitalization for heart failure: A national observational study

SummaryBackgroundNational population-based management and outcome data for patients of all ages hospitalized for heart failure have rarely been reported.AimNational population-based management and outcome of patients of all ages hospitalized for heart failure have rarely been reported. The present study reports these results, based on 77% of the French population, for patients hospitalized for the first time for heart failure in 2009.MethodsThe study population comprised French national health insurance general scheme beneficiaries hospitalized in 2009 with a principal diagnosis of heart failure, after exclusion of those hospitalized for heart failure between 2006 and 2008 or with a chronic disease status for heart failure. Data were collected from the national health insurance information system (SNIIRAM).ResultsA total of 69,958 patients (mean age, 78 years; 48% men) were studied. The hospital mortality rate was 6.4%, with 1-month, 1-year and 2-year survival rates of 89%, 71% and 60%, respectively. Heart failure and all-cause readmission-free rates were 55% and 43% at 1 year and 27% and 17% at 2 years, respectively. Compared with a reference sample of 600,000 subjects, the age- and sex-standardized relative risk of death was 29 (95% confidence interval [CI] 28–29) at 2 years, 82 (95% CI 72–94) in subjects aged<50 years and 3 (95% CI 3–3) in subjects aged≥90 years. For subjects aged<70 years who survived 1 month after discharge, factors associated with a reduction in the 2-year mortality rate were: female sex; age
