Patients with acute decompensated chronic HF (adCHF) usually have more comorbidities, whereas those with de novo acute HF (dn-AHF) may have a more severe clinical presentation. Despite extensive research on HF, comparative data on in-hospital outcomes and mortality between these groups are scarce in Latin American countries. The aim of this study was to evaluate differences in in-hospital complications and mortality among patients hospitalized with either dn-AHF or ad-CHF.  \nMethods: An ambispective study was conducted at a tertiary hospital in Colombia, including 780 patients hospitalized for acute HF. Patients were classified as dn-AHF or ad-CHF, and sociodemographic, clinical, and in-hospital outcomes were compared using bivariate analysis. A Firth penalized logistic regression model was used to assess the association between dn-AHF and in-hospital mortality.  \nResults: Of these patients, 39.2% had dn-AHF, and 60.8% had adCHF. Median ages were 67 (interquartile range (IQR): 56-76) and 66 (IQR: 55-79) years, respectively. Both groups had a predominance of reduced left ventricular ejection fraction, with median values of 30% in ad-CHF and 34% in dn-AHF. Ad-CHF patients had more comorbidities, whereas dn-AHF patients showed higher rates of cardiac and non-cardiac complications. Intensive care unit (ICU) admission rates were similar, the need for invasive mechanical ventilation (P  \nManuscript submitted August 19, 2025, accepted October 25, 2025  \nPublished online December 20, 2025  \naFacultad de Ciencias de la Salud, Universidad Icesi, Cali 760008, Colombia bCentro de Investigaciones Clinicas (CIC), Fundacion Valle del Lili, Cali 760031, Colombia  \ncServicio de Cardiologia, Fundacion Valle del Lili, Cali 760031, Colombia dCorresponding Author: Juan Esteban Gomez-Mesa, Servicio de Cardiologia, Fundacion Valle del Lili, Cali 760031, Colombia.  \nEmail: [juan.gomez.me@fvl.org.co](juan.gomez.me@fvl.org.co)  \ndoi: [https://doi.org/10.14740/cr2135](https://doi.org/10.14740/cr2135)  \n\u003C 0.001) and the occurrence of infections (P = 0.049) were significantly more frequent in patients with dn-AHF. In-hospital mortality was higher in dn-AHF than ad-CHF (9.8% vs. 5.5%, P = 0.023). After adjustment, dn-AHF remained independently associated with greater in-hospital mortality (odds ratio (OR): 1.87; 95% confidence interval  \n(CI): 1.07-3.31; P = 0.029) .  \nConclusions: Patients with dn-AHF experienced more in-hospital complications and higher mortality than those with ad-CHF, despite similar ICU admission rates and fewer comorbidities. These results highlight the prognostic importance of dn-AHF and underscore the need for early identification, vigilant monitoring, and phenotype-specific management from admission to improve outcomes, particularly among patients with reduced ejection fraction.  \nKeywords: Acute decompensated chronic heart failure; De novo acute heart failure; In-hospital mortality; Complications  \nIntroduction  \nHeart failure (HF) is a significant global health problem, affecting more than 64 million individuals worldwide [1] .
