A commonly-used heart drug, digoxin, has never passed a controlled-study test to see if it s both safe and effective for patients with atrial fibrillation. A large VA retrospective analysis shows that it may be even riskier than suspected: maybe time for it to go.
Digoxin, a drug derived from the foxglove plant, is one of the oldest and most widely used treatments for a variety of cardiac conditions. For example, it can regularize the heartbeat in many who have atrial fibrillation and it can strengthen the heart beat for those with heart failure. A new study published in the journal Circulation, however, suggests that its use for adults with heart failure should be reevaluated.
