Video Summary

In this segment of EP on EP, Dr. Jared Bunch, Division Chief of Electrophysiology at the University of Utah, discusses the connection between atrial fibrillation and dementia. The discussion stems from a patient observation that atrial fibrillation may contribute to idiopathic dementia due to altered blood perfusion in the brain. Research shows that atrial fibrillation increases the risk of dementia by two to three times. Studies also highlight the importance of timely and effective anticoagulation in reducing this risk. Dr. Bunch's recent canine study demonstrates a maladaptive response in brain perfusion to atrial fibrillation, shedding light on the impact of rhythm control strategies on cognitive function. Overall, there is a growing understanding that maintaining sinus rhythm through ablation or medications early on may be beneficial for cognitive health in atrial fibrillation patients.
