Medscape (5/5) reports that in over “10,000 patients with different diseases who were receiving warfarin therapy to prevent clots and stroke, those who had atrial fibrillation (AF) as opposed to thromboembolism or a mechanical heart valve were more likely to develop dementia, including Alzheimer’s disease, during about a 7-year follow-up.” The findings were presented at the Heart Rhythm Society 2016 Scientific Sessions.
HealthDay (5/5) reports that the researchers found that “patients on the clot-preventing drug warfarin showed a higher dementia risk if their blood levels of the medication were frequently too high or too low.” Over six to eight years, “almost 6 percent of the atrial fib patients developed dementia, including Alzheimer’s disease – versus less than 2 percent of other warfarin patients.”
