"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

Are Anticoagulants and blood thinners the same thing? How do they thin the blood?

We’ve posted a new FAQ and answer under Drug Therapies and Medicines in our section:

Are Anticoagulants and blood thinners the same thing? How do they thin the blood?

Blood clots are usually good, such as when you get a scrape or cut.

Since A-Fib increases your risk of clots and stroke, blood thinners are prescribed to prevent or break up blood clots in your heart and blood vessels and thereby reduce your chance of an A-Fib-related stroke.

Although referred to as “blood thinners”, they don’t actually affect the “thickness” of your blood.

Anticoagulant Warfarin chemical diagram

Anticoagulant Warfarin

There are two main types: anticoagulants and antiplatelet agents.  They work differently to accomplish the same end effect.

Anticoagulants work chemically to lengthen the time it takes to form a blood clot.

Common anticoagulants include warfarin (Coumadin), Heparin and the NOACs such as apixaban (Eliquis).

Antiplatelet Aspirin

Antiplatelets prevent blood cells (platelets) from clumping together to form a clot.

Common antiplatelet medications include aspirin, ticlopidine (Ticlid) and clopidogrel (Plavix) .

Final answer: Yes, an anticoagulant is a blood thinner, but not all blood thinners are anticoagulants.
