Plasma proANP1-98 Response During High Altitude Stress: Effect of Age and Ethnicity

Plasma proANP1-98 levels, reflecting medium-term ANP secretion, decrease during prolonged exposure to HA in LL. This is due to diuresis leading to plasma volume reduction that occurs during the acclimatization process. Ethnicity but not age variation is associated with plasma proANP1-98 under HA stress.
