During routine colonoscopy testing
DEAR DR. ROACH
» I recently had a colonoscopy and was told I was in atrial fibrillation. I’m 71 years old and have never had this before. I was told to see a cardiologist ASAP. I called my doctor, who put me on Eliquis without seeing me because it was going to be a month before the heart doctor was available. When I saw him, I was fine and had no atrial fibrillation, but he said I should stay on Eliquis. It sounds like I’m stuck taking this very expensive medicine for the rest of my life. What would you recommend?

ANSWER » Atrial fibrillation is a common abnormal heart rhythm that is of major concern because it increases the risk of a blood clot forming in the heart and going to the brain, causing a stroke. When AFib comes and goes, it is called “paroxysmal atrial fibrillation”; however, it is still dangerous and nearly as likely to cause strokes as AFib that is there all the time. I suspect that you have been in and out of atrial fibrillation for a long time, and they only caught it during the colonoscopy because they were monitoring you with the EKG during the procedure.
There is a risk score for stroke in people with AFib, called the CHA2DS2-VASc score, and you have at least two points due to your age and sex. People with a score of two or higher are generally recommended for anticoagulation treatment. Apixaban (Eliquis) is a common anticoagulant used for AFib, and although it is expensive, it has the benefit of not requiring blood testing. Warfarin (Coumadin) is much less expensive but requires periodic blood testing and a careful diet to be as safe and effective as possible.
Everyone who’s prescribed anticoagulation should receive a thorough review of the costs and benefits.
