Cardiac Procedure Reduces Risk Of Alzheimer’s And Stroke
New research presented at National Heart Rhythm Society Sessions shows ablation treatment can eliminate serious risks associated with atrial fibrillation
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.
During atrial fibrillation, the heart's two small upper chambers quiver instead of beating effectively. Blood isn't pumped completely out of them, so it may pool and clot. If a piece of a blood clot in the atria leaves the heart and becomes lodged in an artery in the brain, a stroke results. A-fib is the most common heart disorder found in about 2.2 million Americans. Three to five percent of people over 65 have atrial fibrillation.
