Abstract
Pulmonary hypertension (PH) is a vascular disease characterized by pulmonary artery remodeling and right heart failure. PH related to COPD is a precapillary form of the disease, with hemodynamic measurements including a mean pulmonary artery pressure of greater than 20 mm Hg, a wedge pressure of less than 15 mm Hg, and a pulmonary vascular resistance of greater than 3 WU (Woods units), categorized under the World Health Organization classification as group 3. The presence of PH in COPD has been known to increase morbidity and mortality. Limited studies have evaluated treatment options for PH related to COPD.
