Brief Summary

"Atrial fibrillation (AF) is an arrhythmic disease that increases especially in the elderly, increasing the risk of ischemic stroke by 5 times and is a major cause of dementia and cognitive impairment. Cognitive dysfunction accompanying AF occurs regardless of the presence or absence of stroke, and AF itself is known to affect cognitive function. However, since cognitive dysfunction is also affected by various accompanying chronic diseases, whether the cognitive dysfunction accompanying AF is due to subclinical ischemic stroke, cerebral hypoperfusion due to reduced cardiac output, inflammatory reaction or platelet dysfunction are unclear. Recently, this research team reported an improvement in cognitive function with active sinus rhythm therapy such as AF catheter ablation. Nevertheless, it has not yet been proven whether such active and invasive AF treatment affects the improvement of cognitive function or depression by a randomized clinical trial. In this prospective randomized clinical comparative study, the investigators will compare the AF catheter ablation group and drug therapy group in terms of cognitive function tests and depression psychological tests at baseline and a year after treatment. Our hypothesis is that AF catheter ablation is superior to drug therapy to improve cognitive function and depressive mood.

Study Arms (2)

Atrial fibrillation catheter ablation group

EXPERIMENTAL

catheter ablation

Procedure: Atrial fibrillation catheter ablation group

Medical therapy group

ACTIVE COMPARATOR

standard treatment include anti-arrhythmic drug

Drug: Medical therapy group

Interventions

1. Pulmonary vein isolation 2. Additional treatment for lesions caused by non-pulmonary veins 3. Esophageal temperature monitoring to prevent damage to the esophagus 4. Evaluation of procedure time and radiofrequency ablation time 5. Evaluation of complications after the procedure 6. Rhythm follow-up after the procedure is conducted in accordance with the above study design. 7. Conduct a survey on cognitive function and emotion before and 12 months after the procedure

Atrial fibrillation catheter ablation group

1. Use of beta-blockers or calcium channel blockers for pulse rate control 2. Antiarrhythmic drugs are administered to patients with highly symptomatic atrial fibrillation symptoms even after pulse rate control. 3. If symptoms are not controlled even with antiarrhythmic drugs, electrical conversion to restore sinus rhythm. 4. To prevent cerebral infarction, maintain optimal anticoagulant therapy according to the risk score for cerebral infarction. 5. Conduct a questionnaire on cognitive function and emotion before and 12 months after the procedure

Medical therapy group
