Identification of long and very long chain fatty acids, plasmalogen-C16:0 and phytanic acid as new lipid biomarkers in Tunisian coronary artery disease patients.

•A link of both inflammation and vascular severity complication of CAD with LCPUFAs represents an element of novelty in the present study.•The correlation of C26:0 with vascular severity in coronary patients might indicate peroxisomal metabolism alteration in the vascular tissue.•Quantification of VLCSFAs, LCPUFAs, phytanic acid and PL-C16:0 would be of great value for the screening of peroxisomal disorders in CAD.•Peroxisomal disorders appears to be involved in the progression of atherosclerosis.
