Primary outcomePrimary: Albuterol Induced Change in Qaw Before and After Fluticasone or Placebo — 40.9; 0.0 % change

Summary

The hypothesis underlying the proposed study is that the blunted endothelium-dependent vasodilation seen in the airway of current smokers is also present in the brachial artery, and that the same inhaled corticosteroid (ICS) treatment regime that reversed endothelial function in the airway of current smokers will also restore endothelium-dependent relaxation in the brachial artery. Non-smokers will be used as controls and will not receive any intervention or treatment.
