Title: Fish Oil to Inhibit Supraventricular Arrhythmias After Cardiac Surgery: The Fish Trial
Brief Summary: The primary objective of this study is to determine if omega-3 polyunsaturated fatty acids reduce atrial fibrillation and other outcomes after cardiac surgery. In this placebo-controlled trial, patients undergoing elective coronary artery bypass graft surgery with or without valve repair will be treated with omega-3 polyunsaturated fatty acids perioperatively. The following hypotheses will be tested: 1. omega-3 polyunsaturated fatty acids reduces the incidence of atrial fibrillation (AF) after cardiac surgery, 2. omega-3 polyunsaturated fatty acids, administered in the perioperative period for cardiac surgery, decreases postoperative complication rates, and 3. omega-3 polyunsaturated fatty acids decrease intensive care unit and hospital length-of-stay.

  * male sex,
  * hypertension,
  * hypercholesterolemia,

Exclusion Criteria:

* Contraindications (known allergies to n-3 PUFA) or indications (previous myocardial infarction) for the treatment with n-3 PUFA
* Serious comorbidity with an unfavourable prognosis over the short term
* Expected non compliance over a long period of time
* Pregnancy
B: Inclusion Criteria:

* Age 18-85 years old.
* Elective coronary artery bypass (CABG) operation with or without concomitant valve surgery planned for at least 2 days after enrollment.
* Signed, documented informed consent prior to admission to the study.

Exclusion Criteria:

* Urgent or emergent bypass required to be performed \<24 hrs after screening.
* Unstable angina, requiring intervention or CABG \<24 hrs after screening.
* Decompensated congestive heart failure.
* Chronic, persistent atrial fibrillation - patient in atrial fibrillation at the time of screening or enrollment or scheduled for a maze procedure or pulmonary vein isolation at the time of surgery.
* Known sensitivity to Omacor (0mega-3 acid ethyl esters) and hypersensitivity to fish, fish products or corn oil.
* Patients requiring warfarin or Lovenox the 2 days prior to bypass surgery.
* Patients on Class I or III antiarrhythmic agents (quinidine, procainamide, disopyramide, flecainide, propafenone, moricizine, dofetilide, sotalol, amiodarone) or who have taken these drugs within 5 elimination half-lives of the drug (or within 2 months for amiodarone).
* Patients who are pregnant or nursing.
* Patients unable to provide/sign informed consent.
* Patients currently enrolled in another clinical trial without a 30 day washout period.
* Patients currently taking marine based omega-three fish oil supplements.
C: The Alpha Omega Cohort is a prospective cohort study. The cohort originated from the Alpha Omega Trial, a 40-month intervention study of low doses of n-3 fatty acids (in margarine spreads) and cardiovascular events (NCT00127452). The in/exclusion criteria were defined for the Alpha Omega Trial.

Inclusion criteria:

* Written informed consent

Exclusion criteria:

* Living in a nursing home or other institution
* Participation in another scientific study
* Habitual margarine intake \< 10 g per day
* Habitual fish intake \> 150 g per day
* Habitual alcohol intake \> 6 drinks per day
* Use of fish oil capsules or other supplements containing omega-3 fatty acids
* Presence of cancer with \< 1 y of life expectancy
* Cognitive impairment, as indicated by the Mini Mental State Examination (score \<= 21)
* Unintended weight loss \> 5 kg in the past year
* Lack of facilities for cooled margarine storage at home
* Inability or unwillingness to comply with study procedures
D: 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
