Histograms of LVESVI, LVEDVI, LVMI, and 3D LVEF Tabulations of frequencies of left ventricular end-systolic volume (A), end-diastolic volume (B), mass indexed to body surface area (C), as well as 3-dimensional ranges for left ventricular ejection fraction (D), revealed an overall bell-shaped distribution for all measures of left ventricular volumes, mass, and function. LVEDVI = left ventricular end-diastolic volume index; LVEF = left ventricular ejection fraction; LVESVI = left ventricular end-systolic volume index; LVMI = left ventricular mass index; 3D = 3-dimensional.
