According to Dr. Louise Moist, a Scientist at Lawson Health Research Institute, fish oil may also improve outcomes for kidney patients undergoing hemodialysis.
Hemodialysis can be delivered through arteriovenous (AV) grafts, artificial vessels created to join an artery to a vein. Unfortunately, AV grafts are prone to congestion and clotting, causing disruptions to treatment and a need for surgical correction.
Research suggests fish oil could prevent AV grafts from clotting and reduce related cardiovascular events. In a new multi-centre, randomized clinical trial, Dr. Moist and her colleagues followed patients undergoing hemodialysis using new AV grafts for 12 months after creation. Patients were assigned to daily doses of either four fish oil capsules, or four placebo capsules.
Results show those patients taking fish oil experienced a lower rate of graft failure, with half as many grafts lost to clotting. The amount of time until clotting occurred increased, and fewer corrective interventions were required. In addition, those taking fish oil had lower blood pressure, and lower rates of heart attacks, heart failure and other cardiac-related events.
