Effect of an Inhaled Glucocorticoid-long-acting Beta Adrenergic Agonist on Endothelial Function in COPD
In the present study, the investigators wish to address the effect of a glucocorticoid/long-acting beta-agonist preparation on endothelial function in COPD patients who do not currently smoke (ex-smokers) by measuring endothelium-dependent (albuterol response) and endothelium-independent (NTG response) vasodilation in the bronchial artery, reflecting endothelium-dependent and endothelium-independent vasodilation (drug-induced increase in Qaw, ΔQaw). With this approach the investigators will test the hypothesis that in stable ICS-naïve COPD patients, endothelium-dependent vasodilation is restored with a glucocorticoid/long-acting beta-agonist preparation, presumably resulting from the glucocorticoid component.

Primary outcomes
- long term effect of a glucocorticoid/long-acting beta-agonist on endothelial function in the bronchial artery. — 3 weeks
To determine the effect of a medium dose glucocorticoid/long-acting beta-agonist preparation (250 μg fluticasone plus 50 μg salmeterol) or placebo administered for 3 weeks on inhaled albuterol and sub-lingual NTG induced vasodilation in the bronchial artery, as assessed by ΔQaw in stable glucocorticoid-naïve COPD patients, and to re-assess the responses after a 3 week washout period.
