Association of aortic stiffness with LV diastolic dysfunction. Independent association of PSEM (units) with (A) mitral E/A ratio, (B) E′/A′ ratio, (C) E′ peak velocity, and (D) E/E′ ratio (P ≤ 0.009 for each parameter and P < 0.001 by rANOVA as a profile). The association of PSEM with LV diastolic dysfunction was computed as least squares means over the range of PSEM values, controlling for relevant covariates set to their mean values (red lines). The unadjusted linear regression fits (black lines) to the scatter plots of raw data (open blue circles) are shown for comparison purposes. Abbreviations: ASA, aspirin; C3, complement C3; LV, left ventricular; MAP, mean arterial blood pressure; PSEM, pressure‐strain elastic modulus; rANOVA, repeated measures analysis of variance; SLICC, Systemic Lupus International Collaborating Clinics; STB, standardized β; tPA, tissue plasminogen antigen.
