Figure 1. — (A): Normal adults have a relatively low ratio of Ea to Ees. Isolated changes in preload EDV with normal elastance values leads to increases in SV and SBP; (B): Individuals with HFPEF have an increased ventricular and arterial eleastance. The same increase in EDV produces a larger increase in SBP with out a proportional augmentation in SV. This decreased elastance explains why older adults have labile SBPs in response to changes in preload especially during exercise. Ea: arterial elastance; EDV: end-diastolic volume; Ees: left ventricular elastance; HFPEF: heart failure with preserved left ventricular systolic function; LV: left ventricular; SV: stroke volume; SBP: systolic blood pressure.
