Intravenous Fish Oil in Critically Ill Cardiac Patients (FO-cardiac)

February 14, 2016 updated by: Mette M Berger, Centre Hospitalier Universitaire Vaudois

Effects of Intravenous n-3 Polyunsaturated Fatty Acid Administration in Critically Ill Cardiac Surgery and Myocardial Infarction Patients

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.

Detailed Description

A. Randomized trial in 40 cardiac surgery patients Early rapid infusion of fish oil (3 times in 24 hours) in cardiac surgery patients.

B. Randomized trial 20 myocardial infarction patients (abandonned) Continuous infusion of the same dose over 24hrs in the myocardial infarction patients

Additional trial in healthy volunteers (investigating physiological changes after cardiac study):

-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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
