Clinical Trial 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.
Description:
Study design
1. Prospective randomization (catheter ablation group vs. drug treatment group) (Python
program is used, the random number module is imported using the import random syntax,
and the random number table of the two groups is prepared and used)
2. Target number of targets 320 (160 for each group)
3. Cardiac rhythm follow-up: 2012 ACC/AHA/ESC guidelines (baseline, 3 months, every 6
months after Holter, Electrocardiogram when symptoms are present)
4. Anticoagulant therapy follows 2014 ACC/AHA/ESC guidelines.
5. Evaluation of MOCA score (cognitive function), CES-D score (depression), and GAD-7 score
(anxiety) at baseline and a year after treatment, respectively.
6. Evaluation of all adverse events occurring in each group, hospitalization rate, major
cardiovascular attack, and mortality rate comparison
Progress and rhythm/ ECG follow-up
1. Implemented in accordance with 2012 ACC/AHA/HRS guidelines for AF management
2. Baseline MOCA, CES-D, and GAD-7 score evaluation
3. Outpatient follow-up observation 1 to 2 weeks after the start of the procedure or
medication
4. Follow-up observation at intervals of 2 months, 6 months, and then every 6 months after
starting the procedure or medication
5. If the patient complains of arrhythmia symptoms, conduct an electrocardiogram at any
time, and follow the rhythm with a Holter or event recorder.
6. Follow-up MOCA, CES-D, and GAD-7 score evaluation
Follow-up observation
- All patients are scheduled to visit the outpatient clinic every 6 months after 1~2
weeks, 2 months, 6 months, and even if they have symptoms in the middle, they will be
treated as an outpatient at any time.
- An ECG is administered at every outpatient visit. A 24-hour Holter or event recorder was
administered for 1 year at intervals of 2, 6, and 6 months after the procedure (2012
Heart Rhythm Society/EHRA/European Cardiac Arrhythmia Society Expert Consensus Statement
guidelines).
- If atrial fibrillation or atrial tachycardia lasting more than 30 seconds is observed on
a standard electrocardiogram, event electrocardiogram, or Holter, it is evaluated as
recurrence. Recurrence within 3 months after the procedure is classified as early
recurrence, and recurrence after 3 months is classified as clinical recurrence.
