Airway Vascular Endothelial Function in Healthy Smokers Without Systemic Endothelial Dysfunction

Healthy smokers with no signs of systemic inflammation or endothelial dysfunction display impaired airway vascular endothelial function, possibly preceding systemic endothelial dysfunction. Airway endothelial function was restored with an ICS, and the response was directly related to the severity of endothelial dysfunction.
