Minimal attention has been paid to understanding the implications of the chronicity of heart failure (HF) diagnosis on prognosis of hospitalized patients with acute HF (AHF). We aimed to assess the differences in outcomes between hospitalized patients with AHF that are new-onset (de-novo) AHF and acutely decompensated chronic HF (ADCHF). We analyzed data of 2,328 patients with AHF, who were enrolled in the HF survey in Israel. Patients were classified into de-novo AHF and ADCHF. A total of 721 (31%) patients were classified as de-novo AHF and 1,607 (69%) patients were classified as ADCHF. Patients with de-novo AHF were more likely to be younger, with fewer co-morbidities represented by lower Charlson index, and less likely to have past myocardial infarction as well as coronary revascularization. At 30 days mortality rates were similar in both groups (9% vs 8% in de-novo AHF and ADCHF, respectively). Survival analysis showed that at 1 and 10 years the all-cause mortality rates were significantly higher in patients with ADCHF (33% vs 22% and 90% vs 72%, 1 and 10 years, log-rank p < 0.001, respectively). Consistently, multivariable analysis showed that patients with ADCHF had an independently 58% and 48%, higher mortality risk at 1 and 10 years, respectively, (1-year hazard ratio = 1.58; 95% confidence interval 1.05 to 2.38, p = 0.03; 10-year hazard ratio = 1.48; 95% confidence interval = 1.23 to 2.77; p < 0.001). In conclusion, previous history of HF is an independent predictor of 1-year and 10-year mortality after hospitalization for AHF. Distinction between de-novo AHF and ADCHF may improve our understanding and risk stratification of patients with AHF.
