Acute nicotine may raise ET-1 and vasopressin in nonsmokers; hypothesis-generating for cardiovascular risk mechanisms, should not yet change practice.
Does acute nicotine consumption increase plasma endothelin-1 and vasopressin concentrations in healthy nonsmokers?
Acute nicotine consumption in nonsmokers stimulates the release of circulating ET-1, likely via vasopressin activation, which may contribute to the pathogenesis of cardiovascular disorders.
