Comparison of Brain Perfusion in Rhythm Control and Rate Control of Persistent Atrial Fibrillation

Not Applicable
Conditions
Persistent Atrial Fibrillation
Interventions
Registration Number
NCT02633774
Lead Sponsor
Yonsei University
Brief Summary

Atrial fibrillation (AF) is associated with impaired cognitive function (CogF) and/or dementia, but it is unclear whether rhythm control of AF improves CogF or brain perfusion. The hypothesis is rhythm control of AF improves CogF by increasing brain perfusion with hemodynamic amelioration compared to AF state. We will randomize the patients with persistent AF to rhythm control group and rate control group, and check baseline and 3rd month cognitive function (K-MOCA score) and brain perfusion CT. K-MOCA score and brain perfusion CT findings will be compared between rhythm control group and rate control group of persistent AF.

GroupInterventionDescription
Rhythm control groupPropafenone1. Start AAD right after evaluating for LA size, EF, LA thrombus, and presence of CAD during anticoagulation 2. check the echo, brain perfusion CT and K-MOCA on baseline 3. confirm a thrombus through the TEE 4. Cardioversion after 1 month 5. Rhythm FU schedule (2012 ACC/AHA/ESC guidelines) 6. If AF recur, RFCA 7. check the brain perfusion CT, K-MOCA after 3M and 12M
Rate control groupApixaban1. No AAD, just anticoagulation 2. HR control between 60\~110bpm (with beta blocker, calcium channel blocker, digoxin) 3. check the echo, brain perfusion CT and K-MOCA on baseline 4. check the brain perfusion CT and K-MOCA after 3M and 12M 5. Without the treatment about antiarrythmia and rhythm control, diffication of rate control, the subject will be drop out for study.
