Mechanisms of Vascular Damage in Patients With Chronic Obstructive Pulmonary Disease

2014-07-23 21:11:42 | BioPortfolio

Summary

A randomised controlled trial will be performed to evaluate the effects of lung volume reduction surgery (LVRS) in patients with COPD on systemic inflammation, oxidative stress, endothelial function, arterial stiffness and blood pressure. We hypothesize that LVRS will lead to a reduction of systemic inflammation, oxidative stress, arterial stiffness and blood pressure and to improved endothelial function.

For this purpose 30 patients with severe/very severe COPD (GOLD III-IV) and pulmonary emphysema who are to undergo LVRS will be randomised to one of two groups: group 1 receiving immediate LVRS and group 2 receiving LVRS after a delay of 3 months.

Measures of systemic inflammation, oxidative stress, endothelial function, arterial stiffness and blood pressure will be measured at baseline and 3 months after surgery and no surgery, respectively (group 2 receiving surgery only after a delay of 3 months will serve as control group) to investigate the effects of LVRS on the described outcomes.

Medical and Biotech [MESH] Definitions

Any disorder marked by obstruction of conducting airways of the lung. AIRWAY OBSTRUCTION may be acute, chronic, intermittent, or persistent.

A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)

The lung volume at which the dependent lung zones cease to ventilate presumably as a result of airway closure.

Measurement of the volume of gas in the lungs, including that which is trapped in poorly communicating air spaces. It is of particular use in chronic obstructive pulmonary disease and emphysema. (Segen, Dictionary of Modern Medicine, 1992)

The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung. (From Best & Taylor's Physiological Basis of Medical Practice, 12th ed, p562)
