Left ventricular work and left ventricular work index are a measure of cardiac pumping.
Parameters:
(1) mean arterial pressure in mm Hg (MAP)
(2) pulmonary capillary wedge pressure in mm Hg (PCWP)
(2) cardiac output in liters per minute
(4) body surface area in square meters
left ventricular work in kg•m/min=
= (MAP - PCWP) * (cardiac output) * 0.0136
left ventricular work index in kg•m/min per meter-squared =
= (left ventricular work) / (body surface area in square meters)
The mean value for left ventricular work in the study of Fincke et al was 2.61.
