"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

AF Symposium 2017

New 2017 European A-Fib Stroke Risk Guidelines Changes & No Gender Bias

by Steve S. Ryan, PhD, Jan 19, 2017

Background: The controversy began with the HRS/ACC/AHA committee report, 2014 Guidelines for Management of Patients with Atrial Fibrillation. The rating scale, CHA2DS2-VASc, is used by doctors to assess an A-Fib patient’s risk of stroke. Magically, simply because of her gender, a woman with A-Fib is automatically given one point on the stroke risk scale―no matter how healthy she is otherwise.

Dr. John Camm from St. George’s Medical Center, London, UK discussed the new 2017 ESC (European) AF Stroke Risk Guidelines (i.e. CHA2DS2-VASc) compared to AF guidelines used around the world.

Gender Bias Reversed: The big news is that in the 2017 ESC Stroke Risk Guidelines for Atrial Fibrillation “gender is no longer an important consideration.”

The previous CHA2DS2-VASc risk scale automatically gave every woman with A-Fib an additional 1 risk point for just being female. Under the new 2017 Guidelines, anticoagulation recommendations are the same for men with 1 point as for women with 2 points. (“Sc” stands for sex i.e. female gender). This is a major change in anticoagulation treatment for women.

Antiplatelet drugs like aspirin are not recommended.

Anticoagulant Therapy: Under the 2017 European Guidelines, the newer NOACs (Novel Oral Anticoagulants) are recommended over the anticoagulant warfarin (Comadin).

In addition, antiplatelet drugs like aspirin are not recommended. The guidelines explicitly state that bleeding risk should be considered.

Decisions previously dictated by the guidelines now read “patient choice”.

Patient’s choice: Another important change for European A-Fib patients is that many decisions previously dictated by the guidelines now read “patient choice.” For example, it’s now a patient/doctor decision to either try different antiarrhythmic drugs or catheter ablation.

What Patients Need To Know

For a further discussion of the gender controversy, see my article, The Controversy Continues: Women, Anticoagulants, CHA2DS2-VASc and Risk of Bleeding

Keep in mind: all anticoagulants are high risk medications. They work by increasing your risk of bleeding.

Why not drop the “Sc”? Removing the bias against women in the 2017 European A-Fib Stroke Risk Guidelines is a welcome change. But, one wonders why they didn’t just drop the extra point for being female? And make the acronym “CHA2DS2-VA” without the “Sc”? it’s still confusing for women and even for their doctors.

For example, why should a man with hypertension be given 1 point on the stroke risk score, while a woman with hypertension is given 2 points? Even if under the new European Guidelines, a man with 1 point is treated the same as a woman with 2 points, does this make any sense? It sounds like the writers of the Guidelines recognize their error and bias against woman (probably influenced by drug companies), but won’t actually change the guidelines so as not to lose face and acknowledge their error.

This change is historically significant. Dr. Camm was one of the principal authors of the original CHA2DS2-VASc guidelines which automatically gave a woman with A-Fib one point on the stroke risk scale.
