BP= blood pressure; BUN=blood urea nitrogen; HR=heart rate; PADP=pulmonary artery diastolic pressure; PAP=pulmonary artery pressure; PASP=pulmonary artery systolic pressure; PCWP=pulmonary capillary wedge pressure; PVR=pulmonary vascular resistance; RAP=right atrial pressure. Values are expressed as median [25th, 75th percentiles].
The post-LVAD blood pressure is an approximate systolic/mean blood pressure due to the continuous-flow of the LVAD.
