An international study followed people on dialysis who took a daily fish oil supplement. This group had a significant reduction in the incidence of major cardiovascular events compared to the placebo group. Specifically, they had fewer heart attacks. They also had fewer strokes. The number of deaths from cardiovascular causes also decreased. Researchers report that dialysis patients are among those at extremely high cardiovascular risk. The findings therefore represent a significant breakthrough in the care of patients with kidney disease on dialysis.
