The patient is said to have World Health Organization (WHO) Group I PAH. If a patient with these hemodynamics is found to have no significant pulmonary parenchymal, airway, or thromboembolic disease, The most widely agreed upon definition of PAH is a hemodynamic one, the components of which can only be obtained by cardiac catheterization: pulmonary artery mean pressure ≥ 25 mm Hg, pulmonary capillary wedge pressure (or left atrial or left ventricular end-diastolic pressure) 3 Wood units (or 240 dynes-second-cm -5). In truth, one cannot define PAH with echocardiography alone. 2007 49(supplA):342A.Īssistant Professor of Medicine, University of Pittsburgh School of Medicine Director, Pulmonary Hypertension Program Associateĭirector, Cardiovascular Fellowship Program, Cardiovascular Institute, University of Pittsburgh Medical Center, Pittsburgh, Right ventricular myocardial strain distinguishesĬompensated from decompensated function in pulmonary hypertension.
