EurekAlert (May 13, 2010): Cardiac Procedure Significantly Reduces Risk of Alzheimer's Disease and Stroke, Researchers Find
New findings by researchers from the Heart Institute at Intermountain Medical Center in Murray, Utah, reveals treatment of the most common heart rhythm disorder that affects more than two million Americans significantly reduces the risk of stroke, mortality, Alzheimer's disease and other forms of dementia.
According to two new studies by the Intermountain Medical Center research team presented Thursday (May 13) at the national Heart Rhythm Society's 31st Annual Scientific Sessions, patients with atrial fibrillation treated with catheter ablation are less likely to develop Alzheimer's disease or other forms of dementia, and have a significantly reduced risk of stroke and death compared to A-fib patients who were not treated with ablation.
During atrial fibrillation, the heart's two small upper chambers quiver instead of being effectively. Blood isn't pumped completely out of them, so it may pool and clot.
