The study analyzed medical records from the U.S. Department of Veterans Affairs (between 2003 and 2008) for 122,465 people newly diagnosed with atrial fibrillation. Nearly all of the patients were men, and almost one quarter were taking digoxin.
The study found that those taking digoxin were more than 20% more likely to die than those taking other drugs to control their atrial fibrillation.
Turakhia said safer alternatives include beta-blockers or calcium channel blockers.
