Reuters Health - 09/10/2020 - Among patients with atrial fibrillation, the risk for dementia is lowered after successful catheter ablation, a new study suggests. Medical records from nearly 27,000 patients with atrial fibrillation show that those who were successfully treated with ablation were 44% less likely to develop dementia than patients who received medical therapy, researchers reported in the European Heart Journal. "We found that successful ablation significantly reduced dementia by 44% compared with medical therapy but if ablation failed we did not see a significant reduction in risk, said Dr. Daehoon Kim, a clinical fellow in the division of cardiology at Yonsei University College of Medicine in Seoul, Korea. "This suggests that it is maintaining the regular rhythm of the heart with successful ablation, and not ablation itself, that may contribute to the lower risk of dementia in patients with atrial fibrillation and provides evidence to assist cli...
