UNLABELLED Endothelin-1 (ET-1) plays a critical role in the regulation of pulmonary vascular tone. The aim of this study was to investigate the role of ET-1 in the pathogenesis of high altitude pulmonary arterial hypertension (HAPH). METHODS Pulmonary artery pressure (PAP) was measured by echocardiography in permanent residents of the Kyrgyz Republic (3200-4000 m above sea level) both before and 3 h after a single oral dose of ET receptor antagonist, bosentan (125 mg).
