Data are mean±SD, median (interquartile range), or n (%). P values reflect overall group differences with ANOVA comparison across all 3 groups; symbol denotes between‐group comparisons with Bonferonni adjustment. BSA indicates body surface area; LAV, Left atrial volume; LV, left ventricle; LVEDV, left ventricular end‐diastolic volume; LVEF, left ventricular ejection fraction; LVM, left ventricular mass; MHD‐NEG, metabolic heart disease–negative; MHD‐POS, metabolic heart disease–positive; PAAT, pulmonary artery acceleration time; PASP, pulmonary artery systolic pressure; RV, right ventricle; TAPSE, tricuspid annular plane systolic excursion.
P<0.02 vs controls.
P<0.02 vs obese MHD‐NEG participants.
