New Predictor for Risk of Sudden Cardiac Death: EPA/Arachidonic Acid Index
Reference: “A new predictor of risk for sudden cardiac death,” Jabbar
R, Saldeen T, Ups J Med Sci, 2006; 111(2): 169-77. (Address: Department
of Surgical Sciences, University of Uppsala, Sweden).
Summary: In a study involving analysis of blood samples from subjects
who had been taking fish oil daily for six years and subjects who had
not been taking fish oil, researchers conclude that the ratio between
EPA and arachidonic acid (AA) may be a new index used to predict the
risk of sudden cardiac death. Results of previous studies involving
14,000 subjects have shown an inverse relationship between blood levels
of omega-3 fatty acids and risk of sudden cardiac death. In this study,
blood samples collected from both groups of subjects were analyzed for
levels of various fatty acids. Of the six different indices calculated,
the one which looked at the ratio between EPA and AA was found to show
the largest difference between the groups, ranging from as low as 5 in
the non-fish oil group to 118 in the fish oil group. 70% of subjects in
the fish oil group were found to have an index of 50 or greater. The
researchers propose that subjects with an EPA/AA index below 50 should
increa se their intake of omega-3 fatty acids in order to reduce their
risk of sudden cardiac death.
