Patients hospitalized with acute heart failure had very high mortality with the majority of death happened after discharge.
Independent prognostic predictors for 1-year mortality after acute heart failure hospitalization were elderly, history of cerebrovascular accident and NT-proBNP ≥10,000 pg/ml.
Patient who had heart failure reduced ejection fraction had lower mortality than preserved ejection fraction.
Patients with hypertension showed better survival at 1 year after acute heart failure hospitalization.
Registries of patients hospitalized with acute heart failure (AHF) provided useful description of characteristics and outcomes. However, a contemporary registry which provides sufficient evidence on outcomes after discharge is needed.
The study aims to identify 1-year clinical outcomes and prognostic predictors of patients hospitalized with AHF.
This is a retrospective registry which enrolled patients who were hospitalized due to a principal diagnosis of AHF in a tertiary care center in Thailand between July 2017 and June 2019. Baseline characteristics and hospital courses between the deceased patients and the survivors at 1 year were compared. Prognostic predictors for 1-year mortality were analyzed using Cox regression model.
A total of 759 patients were enrolled (mean age of 68.9 ± 15 years, 49.8% men, mean ejection fraction of 47.1 ± 19.2%, 55.7% heart failure reduced ejection fraction (HFrEF)). Among these, 40.7% had no history of heart failure. The in-hospital and 1-year mortality was 5.8% and 21.5%, respectively. Patients with HFrEF had lower 1-year mortality compared to those without (HR = 0.57, p = 0.04). Age ≥ 70 years, the history of heart failure, prior heart failure hospitalization, cerebrovascular accident (CVA), reactive airway disease, cancer, length of stay > 10 days and NT-proBNP ≥ 10,000 pg/mL were associated with higher 1-year mortality (p < 0.05). The multivariate analysis showed age, CVA and NT-proBNP were independent predictors.
