Abstract

In a recent article in the Journal, we have reviewed the adverse cardiovascular outcomes observed with digoxin use in the PALLAS study.1 The PALLAS study was designed to determine if dronedarone would reduce major vascular events in patients with permanent atrial fibrillation (AF).2 However the study was stopped early because of safety reasons, as a significant number of patients on the dronedarone arm reached the co-primary end point composite of stroke, myocardial infarction, systemic embolism, or cardiovascular death. Data sub-analyses suggested that digoxin-dronedarone interaction was responsible for the higher arrhythmic death rate observed in the trial. These observations are consistent with several other studies that demonstrate the potential hazard of the use of digoxin in heart failure and/or atrial fibrillation.

A more recent article published in the Lancet studied the use and outcomes of digoxin in the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism in Atrial Fibrillation (ROCKET AF) trial.3 The investigators concluded that digoxin treatment was associated with a significant increase in all-cause mortality, vascular death, and sudden death in patients with AF.
