Figure 2 Distribution of LVIDd Indexed to Body Surface

(Top) Histogram of the distribution of left ventricular internal dimensions in diastole (LVIDd) indexed to body surface area (BSA) among control subjects and hypertensive subjects with a normal ejection fraction with (HFNEF) and without (HTN) heart failure for men (right) and women (left). (Bottom) The gaussian distributions of LVIDd for the 3 groups (control, HTN, and HFNEF), demonstrating normal distributions with a shift in the HFNEF subjects toward larger volumes for men (right) and women (left).
