Journal ArticleDOI
Assessment of systolic and diastolic ventricular properties via pressure-volume analysis: a guide for clinical, translational, and basic researchers.
TL;DR: This review summarizes the basic concepts underlying pressure-volume analysis of ventricular and myocardial systolic and diastolic properties, deviations from ideal conditions typically encountered in real-life applications, how these relationships are appropriately analyzed, including statistical analyses, and the most common problems encountered by investigators and the appropriate remedies.
Journal ArticleDOI
Efficiency of energy transfer from pressure-volume area to external mechanical work increases with contractile state and decreases with afterload in the left ventricle of the anesthetized closed-chest dog.
TL;DR: Ees, which was smaller than Ea before dobutamines, became nearly equal to Ea after dobutamine, maximizing EW for a given end-diastolic volume, and could account for all changes in EW/PVA efficiency by the relative changes in Ees and Ea in the pressure-volume diagram.
Journal ArticleDOI
Logistic time constant of isovolumic relaxation pressure-time curve in the canine left ventricle : better alternative to exponential time constant
TL;DR: It is concluded that the logistic model better fits LV isovolumic relaxation P(t) than the monoexponential model in the present heart preparation and is proposed as a better alternative to TE for evaluating LV lusitropism.
Journal ArticleDOI

TL;DR: In this paper, the authors investigated cardiac function in terms of the coupling of left ventricular mechanical work and the energetics in Otsuka Long-Eva patients with diabetic cardiomyopathy.
Journal ArticleDOI
Regression of cardiac oxygen consumption on ventricular pressure-volume area in dog
TL;DR: Left ventricular systolic pressure-volume area (PVA) has been reported to be a reliable predictor of cardiac oxygen consumption rate per beat (VO2) in a given heart with a stable inotropic background and the optimal combination of EW and PE was determined, corroborating that PVA, i.e., a simple sum ofEW and PE, can reliably predict VO2 of a givenheart in a stable contractile state.
