High-altitude pulmonary hypertension appears independent of sympathetic activity; hypothesis-generating for non-SNS mechanisms in mountaineers.
Does sympathetic nervous system activity contribute to high-altitude pulmonary hypertension in mountaineers?
The degree of pulmonary hypertension occurring upon high-altitude exposure appears largely independent of sympathetic nervous system activity in the pulmonary vasculature and adrenal gland.
Berger et al. (2010) studied this question.
