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

Among dyspneic patients, we identified abnormal exercise phenotypes based upon ΔmPAP/ΔCO, ΔPAWP/ΔCO, and PP/PAWP responses. Our study refines quantitative classification of abnormal exercise hemodynamic phenotypes based on an improved understanding of the interrelationship between left heart filling pressure and pulmonary vascular behaviour.
