How safe is revlimid (lenalidomide) tx in a patient with atrial fib?

It depends... Revlimid (lenalidomide) is an important treatment for myelodysplastic syndromes. Not treating these syndromes may be more dangerous than being on revlimid (lenalidomide). That said, I would be particulary concerned about blood clot formation. Both a. Fib and Revlimid (lenalidomide) increase your tendency to form blood clots in your heart. Talk to your doc about whether or not you need to be on anticoagulants w/ revlimid (lenalidomide).
