Discussion

Implication

PVA reliably indexes myocardial VO2 in canine hearts; leaves open translation to human cardiac energetics.

Structured PICO

Population

Dog hearts (n=7)

Intervention

Linear multiple regression analysis of external mechanical work (EW) and end-systolic elastic potential energy (PE)

Outcome

Prediction of cardiac oxygen consumption rate per beat (VO2)surrogate

Left ventricular systolic pressure-volume area (PVA), as the sum of external mechanical work and end-systolic elastic potential energy, reliably predicts cardiac oxygen consumption per beat in dog hearts.
