BSA – body surface area, LA – left atrium, LV – left ventricle, EDVI – end-diastolic volume index, PEA – proportion of European Ancestry.

Values are the coefficient (β ± SE) for each 1 SD increase in arterial elastance adjusted by age, sex, body mass index, use of anti-hypertensive, diabetes mellitus, heart rate and prevalent coronary heart disease or heart failure.
