Values are means±SD or percentages. Group 0: LVEDV/BSA <56 mL/m2 and averaged E/e′ ≤8; group 1: LVEDV/BSA ≥56 mL/m2 and averaged E/e’ ≤8; group 2: LVEDV/BSA ≥56 mL/m2 and averaged E/e′ >8; group 3: LVEDV/BSA <56 mL/m2 and averaged E/e′ >8.
* LV mass/BSA was calculated using the following formula: (0.8×(1.04×(LVDd+IVSd+PWd)3−(LVDd)3))+0.6/body surface area (28).
BSA, body surface area; LA, left atrial; LV, left ventricular; LVEDV, left ventricular end-diastolic volume.
