↵3-150 aCL = anticardiolipin antibodies; SLE = systemic lupus erythematosus; APS = antiphospholipid syndrome; pAPS = primary APS; SLE/APS = APS secondary to SLE; SLE/aCL = SLE with aCL (without APS); SLE/no aCL = SLE without aCL or APS; IVRT = isovolumic relaxation time; E/A = ratio of E wave to A wave; DT = deceleration time; for definitions of groups of subjects see “Methods”.
↵3-151 There were no formally statistically significant differences in the E wave or in the A wave alone between the five groups (not shown).
