Values are mean (SD). LVEDV, LVESV, LVSV, LAV, and LVM were indexed to body height (m). A indicates mitral late peak velocity; E, mitral early peak velocity; E/A, early diastolic and atrial ratio; E/e', ratio of mitral early peak velocity/mitral annulus early peak velocity; e', mitral annulus early peak velocity; Ecc, circumferential peak systolic strain; Ecc_SRe, circumferential peak early diastolic strain rate; Ecc_SRs, circumferential peak systolic strain rate; Ell, longitudinal peak systolic strain; Ell_SRe, longitudinal peak early diastolic strain rate; Ell_SRs, longitudinal peak systolic strain rate; IVS, interventricular septum thickness; LA, left atrium; LVEDV, left ventricular end‐diastolic volume; LVEF, left ventricular ejection fraction; LVESV, left ventricular end‐systolic volume; LVM, left ventricular mass; LVSV, left ventricular stroke volume; PW, posterior wall thickness; RWT, relative wall thickness.
P<0.05: vs white women as the referent group among race–ethnicity and sex groups.
