  1. LV left ventricular.
  2. aThis was derived by measuring LV thickness in 3D space at thousands of points throughout the ventricle for each subject, and taking the 90th percentile of all these measurements
  3. bOne of the 29 healthy weight subjects did not complete cine imaging and was therefore not included in any of the measures of cardiac geometry or LV ejection fraction
