Background: The clinical management of severe congestive heart failure (CHF) should be graded according to the prognosis of each individual patient. Our objective was to elaborate a prognostic rating system for severe CHF.
Methods: The EPICAL program (Epidémiologie de l'Insuffisance Cardiaque Avancée en Lorraine) identified patients with severe CHF defined by hospitalization accompanied by class III/IV dyspnea, edema, or hypertension; an ejection fraction </=30% or a cardiothoracic index >/=60%. Baseline variables were tested in Cox multivariate models.
Results: Patients with ischemic heart disease (n = 219) had a lower 1-year survival rate (57.6%) than patients with dilated cardiomyopathy (n = 182) (69. 1%). Multivariate analysis identified 5 prognostic factors for ischemic CHF and 7 for CHF caused by dilated cardiomyopathy. These variables were used to classify patients within prognostic subgroups of good (>75%), intermediate, or poor (</=25%) 1-year survival.
Conclusion: A score for prognostic prediction was further derived from readily available data to help physicians improve decision making and to assist in clinical trials as a stratification tool.
