Table 2 Clinical history, measured hemodynamic data and calculated passive and active elastance parameters (Ep and Ea) for subjects (HEL, DDM and ML). Where LVP: left ventricle chamber pressure, AOP: aortic pressure, EDV: end-diastolic volume, ESV: end-systolic volume, EF: ejection fraction, MI: myocardial infarct, DVD: double vessel disease, HTN: hypertension, IMH: idiopathic myocardial hypertrophy, Ea,max: maximum active elastance
From: Passive and active ventricular elastances of the left ventricle
