Title: N-3 Polyunsaturated Fatty Acids (n-3 PUFAs) in the Prevention of Atrial Fibrillation Recurrences After Electrical Cardioversion. A Prospective Randomized Study.
Brief Summary: The purpose of this study is to determine the effect of n-3 PUFAs in addition to amiodarone and renin-angiotensin-aldosterone system (RAAS) inhibitors on the maintenance of sinus rhythm after electrical conversion in patients with persistent Atrial fibrillation (AF).


Options:
A: Inclusion Criteria:

* persistent Atrial Fibrillation (AF) lasting \> one month
* history of at least one AF relapse after previous electrical or Pharmacological cardioversion

Exclusion Criteria:

* left atrium size \> 6 cm
* severe valvulopathy
* myocardial infarction during the previous 6 months
* unstable angina
* NYHA heart failure class IV or hemodynamic instability
* cardiac surgery during the previous 3 months
* significant pulmonary thyroid and hepatic disease
* contraindications to treatment with amiodarone or RASS inhibitors
* chronic renal dysfunction
* QT \> 480 msec in the absence of bundle-branch block
* bradycardia \< 50 b/min
* diagnosis of paroxysmal AF
* hyperkalemia
* pregnancy
* any disease or other medical treatment that, in the opinion of the investigators, could interfere with the study.
B: 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
C: Inclusion Criteria:

1. Male or female subject, age 17 or older; country-specific age limitations will be followed
2. Diagnosis of Crohn's disease confirmed by radiological studies or endoscopy or surgical pathology within 36 months prior to randomisation
3. In remission for at least 3 months, but no longer than 12 months; remission being defined as meeting both of the two conditions: (1) clinically in remission with a CDAI of less than 150 and (2) off steroids and/or immunosuppressants for at least 3 months, if remission had been induced with such medications

Exclusion Criteria:

1. Intolerance of omega-3 fatty acids or known allergy to fish or fish products
2. Ongoing CD therapy with: 5-ASA compounds, steroids, immune modifiers, systemic antibiotics, tube feeding, defined formula diets or parenteral nutrition
3. In 3 months prior to randomisation received: systemic steroid therapy, azathioprine, 6-mercaptopurine, methotrexate, cyclosporine, probiotic products or preparations containing fish oil
4. In 12 months prior to randomisation received: biologicals e.g. enbrel, infliximab, mycophenolate, tacrolimus, thalidomide, other immune modifiers and/or investigational products
5. Chronic use of narcotics for pain control (opiates for diarrhoea are acceptable)
6. Documented short bowel syndrome, ostomy
7. Need for bowel surgery for CD, bowel obstruction or resection in past 3 months (a subject who had a bowel resection in the past must have had at least one relapse after the surgery)
8. Malignancy and/or clinically significant impairment in cardiac, liver or renal function, CNS, pulmonary, hematological, immunological, vascular and gastrointestinal disease in addition to CD
9. Known alcoholism or drug abuse
10. Any medical conditions which, in the investigator's opinion, may interfere with the evaluation of the trial medication
11. Any of the following laboratory abnormalities:

    * White blood count \< 3 x 109/L
    * Lymphocyte count \< 0.5 x 109/L
    * Haemoglobin \< 80 g/L
    * Platelet count \< 125 x 109/L or \> 800 x 109/L
    * ALT or AST \> 2.0 times the upper limit of normal
