Figure 1. LV functions determined by pressure-volume relationships.

Figure 1

Representative examples of pressure-volume relationships in LETO (A) and OLETF (B) and summary data of LVEDP (C), tau (D), LV Ees (E), and LV Eed (F) are shown. *p<0.05 vs. LETO, †p<0.05 vs. OLETF. n = 5∼6. LVEDP =  left ventricular end-diastolic pressure; tau =  time constant of left ventricular pressure decay; Ees =  end-systolic elastance; Eed =  end-diastolic elastance; 4-PBA = 4-phenylbutyric acid.
