[REMI-ICAR: Argentine multicenter registry of hospitalization due to heart failure in medical clinic services].

Le résumé fourni par la source

INTRODUCTION: Acute heart failure (AHF) is a leading cause of hospitalizations and mortality worldwide. However, there is limited information regarding its management in general internal medicine units by internal medicine specialists, the usual providers of care for these patients in Argentina. MATERIALS AND METHODS: This multicenter study was conducted between January and October 2024, including patients hospitalized for AHF in internal medicine or progressive care units at public and private hospitals. Sociodemographic data, clinical history, complementary studies, pharmacological treatments, and in-hospital outcomes were collected. RESULTS: Thirty-one hospitals participated, enrolling 713 patients (52.6% women) with a median age of 78 years (IQR 65-87). Hypertension was the most prevalent comorbidity (79.7%), followed by diabetes (32.9%) and atrial fibrillation (32.1%). The most frequent cause of decompensation was infection (36.9%). A transthoracic echocardiogram was performed at admission in 46% (n=331) of patients, only seven of which were performed by internists. At discharge, a significant increase in guideline-directed pharmacological prescriptions was observed, particularly sodium-glucose cotransporter-2 inhibitors (SGLT2i), from 8.5% before admission to 24.9% at discharge. In-hospital mortality was 11.9% (n=85). CONCLUSION: This first Argentine multicenter registry of AHF in patients hospitalized in internal medicine units included older individuals with multiple comorbidities, showing high in-hospital mortality rates comparable to international series. Therapeutic prescriptions at discharge were suboptimal according to current guideline recommendations, underscoring the need to strengthen multidisciplinary approaches and implement strategies to improve quality of care.
