A large body of evidence has accumulated showing that n-3 PUFAs exert extensive cardiac effects. The development of commercial solutions of FO opens perspectives for therapeutic applications in patients with acute cardiac conditions.the 3 following hypotheses will be addressed in patients requiring cardiac surgery under cardiopulmonary bypass or after myocardial infarction:perioperative /post-PTCA intravenous fish oil modifies the composition of membrane phospholipids in platelets and cardiac cells, blunts the physiological response to cardiac surgery/myocardial infarction, and reduces the incidence of arrhythmias, and reduces the occurrence of systolic dysfunction.

Further study details as provided by Centre Hospitalier Universitaire Vaudois:

Primary Outcome Measures:
  • Incorporation of n-3 PUFA into platelet cell membrane and myocardial tissue [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
    Changes in fatty acid cell membrane composition are likely to be the mechnism underlying other effects of omega-3 on the inflammatory and metabolic response

Secondary Outcome Measures:
  • Inflammatory and metabolic response, Clinical outcome [ Time Frame: 72 hours for lab variables, 10-15 days for clinical outcome ] [ Designated as safety issue: Yes ]
    Holter monitoring during 24 hrs (cardiac surgery) or 72 hours (MI), clinical monitroing of cardiac function, cytokine determination, glucose control, length of mechanical ventilation, length of ICU and hosptial stay

Enrollment: 31
Study Start Date: January 2008
Study Completion Date: April 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo
No lipid emulsion - only saline
Drug: normal saline 0.9%
3 infusions, perioperative or post-PTCA
Experimental: Fish oil
3 infusions of fish oil within 24 hours in cardiac surgery, or continuous infusion post-PTCA
Drug: Fish oil emulsion
0.2 g/kg FO, 3 times in 24 hours, infused over 3 hours each in cardiac surgery, or continuous infusion of 0.6 g/kg post PTCA
Other Name: Omegaven,Fresenius Kabi AG

Detailed Description:

Randomized trial in 40 cardiac surgery patients, and 20 myocardial infarction patients Early rapid infusion of fish oil (3 times in 24 hours)in cardiac surgery patients.

Continuous infusion of the same dose over 24hrs in the myocardial infarction patients

Addenda in healthy volunteers:

  1. Open trial in 8 healthy lean volunteers to investigate the impact of the same 0.6 g/kg FO dose IV (Week 1: 3hrs), and then orally on week 2, on platelet n-3 PUFA incorporation, platelet function, heart rate and peak flow response to stress test.
  2. Randomized single blind trial to prepare the next FO trial in obese: 8 different healthy obese subjects will be submitted to an LPS test (2ng/kg actual weight) to investigate their stress responses.
