Pressure-strain product reflects left ventricular stroke work under a wide range of left ventricular assist device support levels
PSP significantly correlated with PV loop-based LVSW at various LVAD support levels. PSP can be a non-invasive parameter for assessing myocardial metabolism under LVAD support, potentially reflecting myocardial oxygen consumption.
