Doctors & patients are saying about 'A-Fib.com'...


"A-Fib.com 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.”

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


The Controversy Continues: Women, Anticoagulants, CHA2DS2-VASc and Risk of Bleeding

The controversy began with the publication of the 2014 Guidelines for Management of Patients with Atrial Fibrillation (A-Fib). The joint HRS/ACC/AHA committee report included significant changes to the rating scale used by doctors to assess an A-Fib patient’s risk of stroke (The rating scale now used is the CHA2DS2-VASc).

Magically, simply because of her gender, a woman is automatically given one point on the stroke risk scale no matter how healthy she is otherwise.

Yes, you read that correctly!

Just because of gender, ALL women automatically have one strike against them when assessing their risk of A-Fib-related stroke.

All it takes is one additional point, say for having hypertension, and the Guidelines call for life-long anticoagulant drug therapy. (It doesn’t seems to matter if your hypertension is under control with meds.) A score of 2 or higher (out of 10) = lifelong anticoagulation therapy!

Really?

Note: These Guidelines aren’t really just “guidelines”. In effect, they become the law of the land. Doctors who don’t follow them can lose malpractice lawsuits and even their medical license.

Research Studies Challenge the 2014 Guidelines

A large Swedish retrospective study by Friberg challenges the 2014 A-Fib Guidelines. The study looked at 140,420 A-Fib patients with a CHA2DS2-VASc score of 1.

The annual stroke risk score for women was 0.1%-0.2%. (In plain language, 0.1% is miniscule. That’s 1/10th of one percent.) Men had an annual stroke risk of 0.5%-0.7%.

Translation: A 0.1%-0.2% risk of stroke for women does not support adding ‘Female gender’ as a factor on the CHA2DS2-VASc stroke risk assessment.

A 2012 study from Denmark (Amson) and 2015 studies in Taiwan (Chao) and Israel (Amson) have similar findings and conclusions. Taiwan researchers concluded:

“Not all risk factors in CHA2DS2-VASc score carry an equal risk.”

Dr. John Day, Intermountain Medical Center, in an editorial in The Journal of Innovations in Cardiac Rhythm Management, wrote:

“Somehow I think we have lost sight of the total picture with the new [2104] A-Fib management guidelines. In my mind, I am not convinced that the long-term stroke risk of a CHA2DS2-VASc score of 1 or 2 (depending on which risk factors are present) justifies all of the risks of life-long anticoagulation therapy… .”

The Danger of Anticoagulants: Increased Bleeding

“The risks of life-long anticoagulation therapy” Dr. Day refers to is the very real danger of increased bleeding. Bleeding events are common complications of taking anticoagulants.

The associated risk of bleeding may be more dangerous than your risk of stroke.

Taking an anticoagulant isn’t like taking a daily vitamin. For example, if you take too much Vitamin C, your body will expel the excess through your urine. No harm done.

An anticoagulant should not be prescribed as a precaution, but only when a significant risk of stroke exists.

Safer, Healthier Alternatives to Anticoagulants

Don’t worry. If you have A-Fib and need the protection of an anticoagulant (or blood thinner), there are alternatives.

The #1 Alternative: Get rid of your A-Fib.

Request a catheter ablation procedure. Today, you can have an ablation immediately (called ‘first-line therapy’ by your doctor). You don’t have to waste a year on failed drug therapy.

EP and prolific blogger, Dr. John Mandrola wrote: “…if there is no A-Fib, there is no benefit from anticoagulation.”

The #2 Alternative: Close off your Left Atrial Appendage (LAA).

The LAA is where 90%-95% of A-Fib clots originate. Request a Watchman device. The Watchman device is inserted to close off your LAA to keep clots from entering your blood stream.

What Patients Need to Know

Don't Yield at A-Fib.com

Don’t be intimidated into a lifetime of meds

If on anticoagulants, start a conversation with your doctor (take along a copy of this article). Ask what is your CHA2DS2-VASc score.

• If female, don’t let your EP rate your stroke risk higher just because you are a women.

• If your CHA2DS2-VASc score is a 1 or 2, don’t be intimidated into taking anticoagulants or warfarin for the rest of your life.

• Ask about a Catheter Ablation or the Watchman to eliminate (or reduce) your need to take blood thinners.

Show your doctor the research studies and expert opinions cited in this article (click ‘Reference for this article).

Remember if taking anticoagulants:
The associated risk of bleeding may be more dangerous than your risk of stroke.
