Pulmonary hypertension from left heart disease (PH-LHD) is the most common form of PH, defined as mean pulmonary artery pressure ≥25 mm Hg and pulmonary artery wedge pressure ≥15 mm Hg. PH-LHD development is associated with more severe left-sided disease and its presence portends a poor prognosis, particularly once right ventricular failure develops. Treatment remains focused on the underlying LHD and despite initial enthusiasm for PH-specific therapies, most studies have been disappointing and their routine clinical use cannot be recommended. More work is urgently needed to better understand the pathophysiology underlying this disease and to develop effective therapeutic strategies.
