Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Depressed participants will be selected from the angiographic database at the Queen Elizabeth Hospital. Patients will be randomly assigned according to a random numbers system administered by an individual who is independent of the study. All contact between the research nurse (who will determine eligibility) and the person who holds the randomisation schedule will be via email.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software
Masking / blinding
Blinded (masking used)

Summary
Brief summary
The aim of this project is to evaluate the potential for supplementation with long-chain omega-3 fatty acids to relieve depressive symptoms and improve health status in cardiac patients suffering from depression. The study will explore potential mechanisms mediating these benefits, with a particular focus on the role of serotonin transporter gene polymorphisms and changes in cerebral blood flow. It is anticipated that depressive symptoms will be greatest in people who have reduced cerebral blood flow and a particular form of serotonin transporter gene. However, it is expected that omega-3 supplementation will increase serotonin receptor expression and cerebral blood flow, thereby improving depressive symptoms, but that these improvements will be less in people who carry the 5HTT-S gene. It is also expected that omega-3 supplementation will improve peripheral blood vessel function, which will be associated with improvements in depressive symptoms and angina scores.
