Cox regression analysis was used to identify predictors of mortality. Of 21 042 patients admitted, 7759 (36.6%) had AHF. Their median age was 62 years, and 35% were women. De novo heart failure was seen in 39.4% of patients. Most common was AHF-associated acute coronary syndromes (ACS-HF) in 43.0%, decompensated heart failure (DHF) in 33.7%, hypertensive heart failure (HT-HF) in 11.8%, and cardiogenic shock (CS) in 5.2%. Pulmonary oedema (PO) (3.3%) and right heart failure (RHF) (3.0%) were least frequent. Coronary artery disease was the most frequent aetiology in 56.5% of patients, valvular heart disease in 22.4%, and cardiomyopathies in 12.3%. Other less frequent aetiology included adult congenital heart disease (2.5%), lung diseases (2.1%), acute aortic syndromes (1.4%), pericardial diseases (0.8%), and intracardiac tumours (0.3%). Aetiology could not be established in 1.6% of patients. Before admission, patients with worsening chronic heart failure and reduced ejection fraction were treated with renin\u2013angiotensin system blockers (60.4%), beta-blockers (42.5%), or spironolactone (34.4%). The percentages of patients given in-hospital management with intravenous diuretics, vasodilators, inotropes, and vasopressors were 81.2%, 33.4%, 18.9%, and 20.4%, respectively. The overall in-hospital mortality was 17.9% (71.3%, 43.9%, 23.8%, 14.9%, 13.6%, and 10.1% for CS, PO, RHF, DHF, ACS-HF, and HT-HF, respectively; P &amp;lt; 0.0001). Multivariate analysis revealed that PO (hazard ratio [HR] 2.68, 95% confidence interval [CI] 1.73\u20134.14, P &amp;lt; 0.0001) and CS (HR 3.37, 95% CI 2.12\u20135.35, P &amp;lt; 0.0001) were independent predictors of in-hospital mortality. Use of intravenous diuretics was linked to reduction of in-hospital mortality (HR 0.70, 95% CI 0.59\u20130.59, P &amp;lt; 0.0001). By contrast, increased in-hospital mortality was associated with the use of intravenous inotrope or vasopressor (HR 1.49, 95% CI 1.27\u20131.76 and HR 2.91, 95% CI 2.41\u20133.51, P &amp;lt; 0.0001, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Real-world evidence from a university hospital in Latin America shows that the high mortality among patients with AHF may depend, among other factors, on patients' AHF clinical phenotypes.
