Acupuncture in Persistent Atrial Fibrillation
- Conditions
- Persistent Atrial Fibrillation
- Interventions
- Registration Number
- NCT02110537
- Lead Sponsor
- Kyunghee University Medical Center
- Brief Summary
The aim of this trial is to evaluate the effect of acupuncture on prevention of atrial fibrillation (AF) recurrence after electrical cardioversion (EC) for persistent AF patients resistant to the antiarrhythmic drugs (AADs).
- Detailed Description
This is a multicenter, prospective, participant and assessor blinded, randomized, sham-controlled clinical trial with 2 parallel arms. To evaluate the efficacy and safety of acupuncture, a total of 80 persistent AF participants will be recruited and randomly assigned to active acupuncture and sham acupuncture group. Both group commonly take antiarrhythmic medication during study period. These patients who are resistant to drug therapy will get a electrical cardioversion. After cardioversion, the recurrence rate and duration of atrial fibrillation free time will be evaluated.
This trial consists of 2 weeks of observation and medical therapy, 2 weeks of acupuncture intervention before EC, EC and acupuncture intervention, 7 weeks of additional intervention, and 5 weeks of follow-up. After randomization, participants receive 10 sessions of acupuncture treatments over 10 weeks. The outcome is assessed at 2, 4, 6, 8, and 16 week after randomization.

- Primary Outcome Measures
Name Time Method Recurrence of atrial fibrillation evaluated on serial electrocardiography and 48 hour holter monitoring after sinus conversion by electrical cardioversion 3 months after electrical cardioversion When patient feel symptoms such as palpitation and chest discomfort, the patients are recommended to visit hospital to check out the recurrence of atrial fibrillation.
- Secondary Outcome Measures
Name Time Method Changes in function and volume of left atrium and left atrial appendage evaluated by echocardiography 3 months after electrical cardioversion Change of inflammation marker (hsCRP) 3 months after electrical cardioversion Other markers can be added
Number of Participants with Adverse Events (AEs) Participants will be followed for the duration of this study, an expected average 14 weeks All participants and practitioners are taught to report any AEs. If there are any AEs, the following items are recorded by practitioners at each visit and appropriate actions are taken: type of AEs, occurrence date, lost date, frequency of occurrence, severity, causality with the treatment, actions taken with the acupuncture intervention, and actions taken to the participants. Serious AEs, i.e. death or life-threatening events which are required urgent intervention, will be noted to the principal investigators immediately and determine whether the participants are dropped out.
the factor to make atrial fibrillation recur 3 months later after electrical cardioversion we will perform multivariate regression analysis to know which factor makes atrial fibrillation recur irrespective of intervention method.
