Digoxin initiation after an acute heart failure episode and its association with post-discharge outcomes: an international multicenter analysis

Digoxin is commonly used to treat acute heart failure (AHF), especially in patients with concurrent atrial fibrillation (AF). Nonetheless, there is little consensus about in which patients digoxin should be given, the proper time for digoxin initiation, and whether digoxin initiation is associated w...

Description
Summary:Digoxin is commonly used to treat acute heart failure (AHF), especially in patients with concurrent atrial fibrillation (AF). Nonetheless, there is little consensus about in which patients digoxin should be given, the proper time for digoxin initiation, and whether digoxin initiation is associated with improved outcomes. We investigated factors related to digoxin initiation after an episode of AHF and whether patients receiving digoxin presented better short-term outcomes. We analyzed digoxin-naïve AHF patients from a Spanish and Swiss database, who were dichotomized into cohorts based on their receipt of digoxin treatment at discharge. The relationship between digoxin initiation and 23 additional patient covariates, including chronic treatment, was investigated, as well as its association with 90-day combined adverse events (defined as all-cause death or AHF hospitalization). Of 13,105 patients (10,600/2505 from the Spanish/Swiss cohorts, respectively), the median (interquartile range) age was 83 (74.87) years, and 51% were women. Of these, 484 (3.7%) received digoxin at discharge, which was associated with AF, female sex, left ventricular ejection fraction (LVEF)
