Long-term outcome after a first episode of heart failure. A prospective 7-year study

Abstract Background Heart failure (HF) is a major issue of public health in contemporary aging populations. The objectives of the present study were to assess the long-term survival of a contemporary cohort of patients discharged after a first hospitalization for HF and identify variables associated with adverse outcome. Methods We prospectively included consecutive patients ( n = 735) discharged from 11 healthcare establishments of the Somme department (France) after a first hospitalization for HF during 2000. The 7-year observed survival was compared with the expected survival of the general population. Results Mean age of the study group was 75 ± 12 years and 48% of patients were women. Left ventricular ejection fraction was measured in 628 patients (85%). During the 7-year follow-up, 483 patients (67%) died. The 5- and 7-year observed survival rates were dramatically lower than the expected survival of the matched general population (42% vs. 70%, and 33% vs. 59%, respectively). Relative survival (observed/expected survival) was 60% at 5 years and 55% at 7 years. Multivariable analysis identified cancer, stroke, diabetes, prior myocardial infarction, chronic obstructive pulmonary disease, chronic atrial fibrillation, age, and hyponatraemia as independent predictors of 7-year mortality. Conclusions In Europe, the long-term outcome of patients with new-onset HF is still extremely poor. Better implementation of guideline-oriented therapeutic strategies is needed to improve prognosis of this increasingly prevalent condition.
