The Relationship between Pulmonary Artery Pulse Pressure and Pulmonary Artery Wedge Pressure during Exercise in Health and in Patients with Suspected Pulmonary Hypertension

Exercise during right heart catheterization (RHC) can demonstrate cardiopulmonary hemodynamic abnormalities not evident at rest. The relationships of pulmonary artery pressure (PAP) or pulmonary artery wedge pressure (PAWP) to cardiac output (CO) do not fully consider that PAP and PAWP should also be closely related. Therefore, we sought to expand our understanding of cardiopulmonary hemodynamic abnormalities by calculating the ratio of PA pulse pressure to PAWP during exercise in health and in patients with dyspnea and uncertain mechanisms of pulmonary hypertension (PH).
