LESCANO, ADRIÁN et al. Argentine Registry of Acute Heart Failure (ARGEN-IC). Evaluation of a Partial Cohort at 30 Days. Rev. argent. cardiol. [online]. 2020, vol.88, n.2, pp.118-125. ISSN 1850-3748.


Acute Heart Failure is currently an epidemiological problem, with a close correlation with the increase in the population age and the greater survival of patients with cardiovascular diseases.


Evaluate the clinical profile, the diagnostic and therapeutic strategies and the complications during hospitalization and the 12-month follow up of the ARGEN IC Registry.

Materials and Methods:

It’s a prospective, multicenter, national Registry which included 50 health centers (August 2018-March 2019) and included patients with a confirmed diagnosis of acute heart failure with a 12-month follow-up.


A total of 909 patients were included, corresponding to 18 provinces and 73 active researchers. The mean age was 72.2 (SD 14) years, 60.5% of the patients were males. Baseline characteristics include a prevalence of diabetes of 33%, previous AMI 17%, and Atrial Fibrillation 31% and a predominant private security medical coverage (38%) Among the trigger factors of decompensation, 28.5% were associated with unknown causes, 15.7% infectious causes, and 13.5% with food transgression. The ischemic-necrotic etiology (26%), the presentation as mixed congestion (48%) and the impaired ejection fraction (EF) group stand out. 77.6% of the patients were admitted to the critical care unit, with a median overall hospital stay of 8 days and overall mortality of 7.9%. The pharmacological treatment at discharge, including the group with reduced EF: Beta Blockers (BB) 78.7%, ACEI, ARA II or ARNI 70.9% and anti aldosteronic 56.3% and the referral to cardiovascular rehabilitation in 17%. The 30-day follow-up showed a rehopitalization rate of 16.7%, mortality of 5.5% and combined events of 18%. Only 47% accessed the medical consultation.


The ARGEN-IC Registry represents a heterogeneous population, with high middle ages and comorbidities. The diagnostic and therapeutic strategies are underutilized during hospitalization and in the first 30 days, with poor access to the health system. The overall combined rate of in-hospital events and at 30 days remains high.
