Figure 2 Changes in left ventricular (LV) end-diastolic volume (LVDd) (A) or end-systolic volume (LVDs) (B), LV fractional shortening (FS) (C), left atrial diameter (LAD) (D), and the pressure differences across the tricuspid valve (TR dPmax) (E) before and after 24 weeks of treatment in the control and famotidine groups. The p values are tested using 2-way repeated-measures analysis of variance.
