(as you may know) I was recently diagnosed in April 2013 with Afib. I have had Type 1 DM almost 32 yrs, pumper x 15+ yrs. I had been taking 81 mg aspirin for at least 15 yrs--no fail; now with this Afib, the cardiologist has prescribed Xarelto (Rivaroxaban), stop aspirin. Endocrinologist ARNP says, same, no aspirin, as there would be no need. I went to 2 different Electro Physiologists and I posed this question to them--does the Xarelto also protect from platelet aggregation and help prevent those microvascular clots. One said no need for aspirin and the other said the actions are two different things and there is not enough evidence about the Xarelto as a platelet inhibitor. He felt that it would be ok to take the 81 mg aspirin and left it up to me to decide. Says he has people using 2 or 3 varioius anticoags depending on conditons. ( I am on p-i-p rhythmol) Well, damn, don't want a stroke from Afib, but don't want any MI either (I know nothing is guaranteed) So anyone else in the same boat?
