Title: Randomized, Prospective, Placebo-controlled, Multi-center Study to Test the Efficacy of n-3 PUFA for the Maintenance of Normal Sinus Rhythm in Patients With Persistent Atrial Fibrillation
Brief Summary: To demonstrate that in patients with persistent atrial fibrillation who had recovered normal sinus rhythm and treated with the best recommended therapies, the addition of 1 gram / daily of n-3 PUFA is superior to the corresponding placebo for the maintenance of normal sinus rhythm at one year of follow up.


Options:
A: Inclusion Criteria:

* Persistent atrial fibrillation

Exclusion Criteria:

* Contraindications or known hypersensitivity to n-3 PUFA
* Current treatment with n-3 PUFA for any reason
* Heart failure NYHA class IV
* Coronary artery bypass surgery or valve replacement within the past 3 months
* Planned cardiac procedures
* Known sick-sinus syndrome
* Diagnosis of Wolff-Parkinson-White
* Clinical significant valvular etiologies
* Presence of arrhythmia associated with an acute reversible condition
* Advanced chronic lung disease
* Contraindications for anticoagulation therapy
* Pregnancy or lactation
* Any non cardiac illness associated with a life expectancy of \< 2 years
* Treatment with any investigational agent within 3 month before randomization
* Any condition that in the opinion of the investigator would jeopardize the evaluation of efficacy or safety or be associated with poor adherence to the protocol
B: Inclusion Criteria:

* Eligible participants had a total cholesterol level of ≧250mg/dL(6.5m mol/L) at baseline.
* Hyperlipidemic patients with serum total cholesterol of 250mg/dL or more. (Measurement of serum total cholesterol)
* Serum total cholesterol should be measured twice at interval of 2-4weeks. A single measurement is acceptable if the cholesterol is measured by blood collection at fasting under strict compliance with dietary advice after withdrawal of the antihyperlipemic drug.
* (Wash Out) The wash out period of 4weeks (8 weeks for probucol) is necessary in patients under treatment with antihyperlipemic drug. However, if treatment with the antihyperlipemic drug was started within 6 months of the initiation of the study, the patient can participate in the study without the washout period.

Exclusion Criteria:

* Acute myocardial infarction occurring within last 6 months
* Unstable angina pectoris
* A history or complication of serious heart disease(severe arrhythmia, heart failure, cardiac myopathy, valvular disease, congenital disease, etc.)
* Receiving cardiovascular reconstruction within last 6 months
* Cerebrovascular disorders occurring within last 6 months
* Complication of serious hepatic disease or renal disease
* Malignant tumor
* Uncontrollable diabetes
* Hyperlipidemia arising from the following disease: Nephrotic syndrome, hypothyroidism, Cushing's syndrome, secondary hyperlipidemia due to other disease
* Hyperlipidemia due to some drugs such as steroid hormone
* Hemorrhage(hemophilia, capillary fragility, gastrointestinal ulcer, urinary tract hemorrhage, hemoptysis, vitreous hemorrhage, etc.)
* Hemorrhagic diathesis
* Hypersensitivity to the study drug formulation
* Patients intending to undergo surgery
* Patients judged to be inappropriate by the physician in charge
C: Inclusion Criteria:

* Male or female
* 50 years of age or older
* Residing in the community at baseline (includes assisted living facilities, but excludes long-term care nursing facilities)

* No medical contraindications to study participation
* Fluent in English or Spanish
* Corrected vision and hearing sufficient for compliance with testing procedures
* Supervision available for study medication
* Caregiver/study partner to accompany participant to all visits
* Study partner must have direct contact with the participant more than 2 days/week
* Able to ingest oral medication
* Daily DHA consumption less than or equal to 200 mg/day in prior two months estimated by an abbreviated DHA food frequency questionnaire
* Neuroimaging consistent with the diagnosis of AD at some time after the onset of the memory decline
* Clinical laboratory values must be within normal limits or, if abnormal, must be judged to be clinically insignificant by the investigator
* Stable use of cholinesterase inhibitors and memantine is permitted if doses are stable for 4 months prior to enrollment

Exclusion Criteria:

* Non-AD dementia
* Residence in a long-term care facility at baseline
* History of clinically significant stroke
* Modified Hachinski Ischemia score ≥ 4
* Current evidence or history in past two years of epilepsy, seizure, focal brain lesion, head injury with loss of consciousness or DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) criteria for any major psychiatric disorder including psychosis, major depression, bipolar disorder, alcohol or substance abuse
* Sensory impairment which would prevent subject from participating in or cooperating with the protocol
* Use of another investigational agent within two months
* Evidence of any significant clinical disorder or laboratory finding that renders the participant unsuitable for receiving an investigational new drug including clinically significant or unstable hematologic, hepatic, cardiovascular (including history of ventricular fibrillation or ventricular tachycardia), pulmonary, gastrointestinal, endocrine, metabolic, renal, or other systemic disease or laboratory abnormality
* Active neoplastic disease (skin tumors other than melanoma may be included; participants with stable prostate cancer may be included at the discretion of the Project Director)

2. IQ \< 70 and/or history of learning disability.
3. Any pre-existing inflammatory conditions e.g. rheumatoid arthritis.
4. Organic brain disease e.g. epilepsy.
5. treatment with an antipsychotic or mood-stabilising agent.
6. Prior history of intolerance or serious side effects (hepatotoxicity, photosensitivity, blood dyscrasias) to any of the tetracyclines or Omega-3 fatty acids.
7. Concomitant penicillin therapy or concomitant anticoagulant therapy.
8. Active substance abuse (except nicotine or caffeine) or dependence within the last three months, according to DSM-V criteria.
