Relationship Between Resting PCWP and Peak Exercise PVR

Patients with resting PCWP <15 mm Hg (exercise-induced left atrial hypertension) are shown in blue and those with resting PCWP ≥15 mm Hg (resting left atrial hypertension) in red. The mean pulmonary vascular resistance (PVR) at peak exercise was lower in the exercise-induced left atrial hypertension group (1.1 vs 1.4 WU). Patients with peak exercise PVR <1.74 WU have previously been identified as a group with beneficial response to atrial shunt therapy. Abbreviation as in Figure 1.
