Title: Phase 3 A Randomized, Double-blind, Placebo-controlled, Multi-center Study to Evaluate the Effect of Long-chain N-3 Polyunsaturated Fatty Acids (OMEGA-3) on Arrhythmia Recurrence in Atrial Fibrillation
Brief Summary: The general objective of this study is to demonstrate the effectiveness of n-3 fatty acids, 2.4 grams per day, to prevent recurrence of atrial fibrillation in patients with paroxysmal or persistent AF in whom a rhythm-control strategy is planned.


Options:
A: Inclusion Criteria:

1. Age \> 18 years
2. Written informed consent
3. Non-valvular paroxysmal or persistent AF in whom a rhythm control strategy is planned
4. Duration of at least one symptomatic AF episode \> 10 minutes within the past 6 months
5. ECG documentation of AF

Exclusion Criteria:

1. Chronic AF (continuously present for \> 3 months)
2. Myocardial infarction within the past month prior to selection visit
3. Cardiac or thoracic surgery within the past 3 months or likely to be performed during trial
4. Moderate to severe congestive heart failure (NHYA FC III-IV)
5. Known left ventricular dysfunction (EF\< 40%).
6. Mitral stenosis
7. Moderate to severe mitral insufficiency (Grade 3-4/4)
8. AF secondary to an acute reversible condition (untreated or uncontrolled hyperthyroidism, post- operative AF, fever, anemia)
9. Need for anti-arrhythmic therapy for a condition other than atrial fibrillation
10. Wolff-Parkinson-White syndrome
11. Any medical condition making compliance with study treatment unlikely
12. Current use of n-3 fatty acid supplements or use within the past 3 months
13. Pregnancy, breastfeeding, or possibility of becoming pregnant during the study (Patients must have adequate contraception as determined by the investigator),
14. Participation in another study at the same time or within 30 days of randomization.
15. Uncontrolled hypertension (systolic blood pressure \> 180 mm Hg or diastolic blood pressure \> 110 mm Hg
16. Suspected or known allergy to any ingredients in the study product or placebo, fish or shellfish .
B: Inclusion Criteria:

1. NASH with NAS (NASH Activity Score) of \>4 evident on a biopsy performed within 6 months of enrollment.
2. Age 21 years or older.
3. BMI 25 or greater.
4. Ability to provide informed consent.

Exclusion Criteria:

1. Cirrhosis evident clinically or on biopsy.
2. Secondary forms of NASH such as that seen with bariatric surgery or medication induced from such medications as methotrexate, amiodarone, tamoxifen, corticosteroids.
3. Current or past history of diabetes or hyperlipidemia requiring specific drug therapy (see below).
4. Current use of a weight loss medicine, such as a 'fat-burner' or similar agent
5. Alcohol consumption \> 30 g/day, currently or for more than 3 consecutive months within 5 years.
6. Other liver disease (hepatitis C,B, Wilson's, autoimmune, ct-1-antitrypsin and hemochromatosis or HIV
7. Pregnancy or unwillingness to use an effective form of birth control for women of child bearing years.
8. Renal insufficiency (creatinine \> 2), symptomatic coronary, peripheral or neurovascular disease, symptomatic heart failure or advanced respiratory disease requiring oxygen therapy.
9. Inability to provide informed consent.
10. Any condition in the opinion of the primary investigator that would contraindicate the patient's participation.
C: Inclusion Criteria:

* Elderly men with long standing hypercholesterolemia (cholesterol \> 6.45 mmol/L and \< 8.00 mmol/L) with or without coronary heart disease.

Exclusion Criteria:

* Cholesterol \> 8.00 mmol/L, blood pressure \> 170/100
* Uncontrolled hypertension
* Socially or otherwise unsuitable subjects
* Anticipated non compliance
* Other major non cardiac illness expected to reduce life expectancy or interfere with study participation.
D: To be eligible for the study, respondents had to, at study entry,:

1. be men aged 50 or older or women aged 55 or older;
2. have no history of cancer (except non-melanoma skin cancer), heart attack, stroke, transient ischemic attack, angina pectoris, coronary-artery bypass grafting, or percutaneous coronary intervention;
3. have none of the following safety exclusions: history of renal failure or dialysis, hypercalcemia, hypo- or hyperparathyroidism, severe liver disease (cirrhosis), or sarcoidosis or other granulomatous diseases such as active chronic tuberculosis or granulomatosis with polyangiitis (Wegener's);
4. have no allergy to fish or soy;
5. have no other serious illness that would preclude participation;
6. be consuming no more than 800 IU of vitamin D from all supplemental sources combined (individual vitamin D supplements, calcium+vitamin D supplements, medications with vitamin D \[e.g., Fosamax Plus D\], and multivitamins), or, if taking, willing to decrease or forego such use during the trial;
7. be consuming no more than 1200 mg/d of calcium from all supplemental sources combined, or, if taking, willing to decrease or forego such use during the trial;
8. not be taking fish oil supplements, or, if taking, willing to forego their use during the trial
