Doctors & patients are saying about ''...

" is a great web site for patients, that is unequaled by anything else out there."

Dr. Douglas L. Packer, MD, FHRS, Mayo Clinic, Rochester, MN

"Jill and I put you and your work in our prayers every night. What you do to help people through this [A-Fib] process is really incredible."

Jill and Steve Douglas, East Troy, WI 

“I really appreciate all the information on your website as it allows me to be a better informed patient and to know what questions to ask my EP. 

Faye Spencer, Boise, ID, April 2017

“I think your site has helped a lot of patients.”

Dr. Hugh G. Calkins, MD  Johns Hopkins,

Doctors & patients are saying about 'Beat Your A-Fib'...

"If I had [your book] 10 years ago, it would have saved me 8 years of hell.”

Roy Salmon, Patient, A-Fib Free,
Adelaide, Australia

"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

"...masterful. You managed to combine an encyclopedic compilation of information with the simplicity of presentation that enhances the delivery of the information to the reader. This is not an easy thing to do, but you have been very, very successful at it."

Ira David Levin, heart patient, 
Rome, Italy

"Within the pages of Beat Your A-Fib, Dr. Steve Ryan, PhD, provides a comprehensive guide for persons seeking to find a cure for their Atrial Fibrillation."

Walter Kerwin, MD, Cedars-Sinai Medical Center, Los Angeles, CA

Dr. Stanley Nattel, U of Montreal

Some Forms of Fibrosis May Be Reversible

Background: Fibrosis is tissue with fiber-like characteristics; over time it makes the heart stiff, less flexible and weak, overworks the heart, reduces pumping efficiency and leads to other heart problems.

Dr. Stanley Nattel of the University of Montreal, Montreal, Canada discussed whether fibrosis is reversible. In a very hopeful study for Atrial Fibrillation patients, he concluded that some forms or types of fibrosis are indeed reversible.

Heart Attack Fibrosis

Dr. Nattel described a typical heart attack victim who experiences actual heart tissue damage and areas of heart tissue death. In these damaged heart areas, fibrous tissue replaces dead cardiomyocytes (scarring). This form of fibrosis may be irreversible.

A 30% weight lost reduced fibrosis in overweight sheep, as well as inflammation and incidence of A-Fib.

Interstitial (A-Fib) Fibrosis

But A-Fib fibrosis is often “purely interstitial” or reactive to the A-Fib. (“Interstitial” refers to the space between cells or myocytes.) This type of fibrosis may indeed be reversible.

Dr. Nattel described his experiments with overweight sheep. A 30% weight lost reduced fibrosis (collagen formation) in these overweight sheep, as well as inflammation and incidence of A-Fib.

(For more research findings, see Dr. Jose Jalife’s experiments in sheep which reduced fibrosis by 50%: The Holy Grail: Preventing A-Fib by a GAl-3 Inhibitor.)

What Patients Need to Know

Some A-Fib Fibrosis May Be Reversible: This is encouraging for A-Fib patients. Even if you develop fibrosis from being in A-Fib, some of this fibrosis may be reversible.

Returning to normal sinus rhythm may reverse a good deal of fibrosis in your heart.

But much more research needs to be done to figure out how best to reverse A-Fib fibrosis. And some long-term A-Fib fibrosis may indeed be irreversible when it produces lasting scarring (dead fibrotic tissue).

Don’t Live in A-Fib and Develop Fibrosis: If you have A-Fib, you are most likely developing a fibrotic heart. The good news from Dr. Nattel (and Dr. Jalife) is that returning to normal sinus rhythm may reverse a good deal of fibrosis in your heart.

In spite of what you hear in today’s media and advertisements, don’t just live in A-Fib and develop fibrosis! Seek your cure!
