"This book is incredibly complete and easy-to-understand for anybody. I certainly recommend it for patients who want to know more about atrial fibrillation than what they will learn from doctors...."

Pierre Jaïs, M.D. Professor of Cardiology, Haut-Lévêque Hospital, Bordeaux, France

"Dear Steve, I saw a patient this morning with your book [in hand] and highlights throughout. She loves it and finds it very useful to help her in dealing with atrial fibrillation."

Dr. Wilber Su Cavanaugh Heart Center, Phoenix, AZ

"Your book [Beat Your A-Fib] is the quintessential most important guide not only for the individual experiencing atrial fibrillation and his family, but also for primary physicians, and cardiologists."

Jane-Alexandra Krehbiel, nurse, blogger and author "Rational Preparedness: A Primer to Preparedness"


"Steve Ryan's summaries of the Boston A-Fib Symposium are terrific. Steve has the ability to synthesize and communicate accurately in clear and simple terms the essence of complex subjects. This is an exceptional skill and a great service to patients with atrial fibrillation."

Dr. Jeremy Ruskin of Mass. General Hospital and Harvard Medical School

"I love your [A-fib.com] website, Patti and Steve! An excellent resource for anybody seeking credible science on atrial fibrillation plus compelling real-life stories from others living with A-Fib. Congratulations…"

Carolyn Thomas, blogger and heart attack survivor; MyHeartSisters.org

"Steve, your website was so helpful. Thank you! After two ablations I am now A-fib free. You are a great help to a lot of people, keep up the good work."

Terry Traver, former A-Fib patient

"If you want to do some research on AF go to A-Fib.com by Steve Ryan, this site was a big help to me, and helped me be free of AF."

Roy Salmon Patient, A-Fib Free; pacemakerclub.com, Sept. 2013

 FAQs A-Fib Drug Therapy: Warfarin + Aspirin?  

Drug Therapies for Atrial Fibrillation, A-Fib, Afib

8. I’m on warfarin. Can I also take aspirin, since it works differently than warfarin? Wouldn’t that give me more protection from an A-Fib (ischemic) stroke?”

No, combining is dangerous.

Preliminary research indicates that combining anticoagulants (warfarin) and antiplatelets (aspirin) in the same patient is associated with a substantially higher risk of fatal or non-fatal internal bleeding.

There’s no indication that combining warfarin with an antiplatelet (aspirin, clopidogrel, or both) reduces the risk of ischemic stroke.

Added 8/10/15. Aspirin is no longer recommended as first-line therapy:

Aspirin has been downgraded from class 1 in the 2006 guidelines to class 2B in the 2014 guidelines.

In a Danish registry study, aspirin didn’t show any benefit for stroke prevention.1 And in the European ESC guidelines, aspirin is not recommended as first-line therapy for patients with a CHA2DS2-VASc score of 1.2
