"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.

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
2020 AF Symposium Abstract
High Hemorrhagic Risk Factors from NOACs
by Steve S. Ryan
NOAC Hemorrhagic Stroke Risk
When I read in this abstract from Massachusetts General Hospital in Boston, these NOAC findings almost jumped off the page at me! We know that NOACs are high risk meds (though they are certainly better than having an A-Fib stroke). But, add to that, also a high risk of Hemorrhagic risk factors, too?
This is a most important and relevant study for A-Fib patients.
Brain MRI to Detect NOAC Hemorrhagic Stroke Risk
Researchers from Massachusetts General Hospital in Boston used MRI to identify markers of increased intracerebral hemorrhage risk (ICH).
This was a single center study conducted from January 2011 to May 2019. In the study were 282 patients of which 76% had Atrial Fibrillation; Of the 282 patients, 49 were taking NOACs and 233 were taking warfarin. All demographic variables, vascular risk factors, etc. were similar between the two groups.
Study Findings
Analyzing the MRI data of the 282 participants revealed:
• cerebral microbleeds (67%) • moderate-to-severe white matter hyperintensities (76%) • cortical superficial siderosis (excess iron in body tissue) (18%)
In particular, of the 49 patients taking NOACs:
• 97% had at least one of these markers • 60% had two • 4% had all three
Conclusion
Established MRI markers of increased ICH (intracerebral hemorrhage) were common in the NOAC study group.
High hemorrhagic risk markers were present in an overwhelming 97% of NOAC patients.
Editor’s Comments:
Does taking a NOAC long-term mean you’ll eventually develop a hemorrhagic stroke?
No, the researchers didn’t go that far. This was a limited study as the number of patients who were on NOACs was 49 compared to those on warfarin which was 233.
Red Flag Warning: But this study should raise a red flag for anyone taking NOACs long term. Almost all patients on NOACs (97% in this study) had “evidence of neuroimaging markers of high ICH risk.”
The authors recommended that prescribers (and patients) look at nonpharmacological stroke prevention methods. Eliminating the need for lifelong NOAC anticoagulation “may decrease the incidence of fatal/disabling hemorrhages in A-Fib patients.”
