Leukocytes from patients with acute coronary syndrome (ACS) contain and externalize similar amounts of phosphatidylethanolamine (PE)/phosphatidylserine (PS), when expressed on a per-cell basis. A through D, Lipids were extracted from resting or ionophore-activated leukocytes as described in Materials and Methods. Lipid amounts (ng) were determined using liquid chromatography tandem mass spectrometry. Statistical significance was tested with 1-way ANOVA and Tukey post hoc test (P<0.05 considered significant). ACS (n=19: A and B; n=21: C and D), coronary artery disease (CAD) but no ACS (n=18: A and B; n=19: C and D), positive risk factors (RFs) with no significant CAD (n=17: A and B; n=22: C and D), healthy control (HC; n=23).
