Pulmonary veins in high-altitude residents: a morphometric study.
The thickness of the media of pulmonary veins and arteries was morphometrically assessed in 12 normal adults resident at altitudes over 3000 m and 12 resident at sea level. The pulmonary veins in the latter group were very thin walled. The average thickness of the pulmonary venous media in the group of highlanders was significantly thicker but this appeared to be due to prominent medial hypertr...

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 ...

متن کاملHigh-altitude pulmonary hypertension.
High-altitude pulmonary hypertension (HAPH) is a specific disease affecting populations that live at high elevations. The prevalence of HAPH among those residing at high altitudes needs to be further defined. Whereas reduction in nitric oxide production may be one mechanism for the development of HAPH, the roles of endothelin-1 and prostaglandin I₂ pathways in the pathogenesis of HAPH deserve f...
متن کاملHigh Altitude Pulmonary Edema
Over the last three decades, increased awareness and education have lessened the instances of high altitude pulmonary edema (HAPE) encountered by otherwise healthy, active sojourners to high altitude. HAPE had been described in Europe as early as the late 1700s and in South America in the late 1800s and 1900s, when it was thought to be pneumonia and/or fluid in the lungs from heart failure. But...
