Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older with a diagnosis of chronic obstructive pulmonary disease.
✕Probably not a fit
Patients with atrial fibrillation, active cardiac pacing, or established cardiovascular diseases may not benefit from this study.

What this trial studies
This observational project aims to investigate the overactivity of the sympathetic nerve activity (SNA) axis in patients with chronic obstructive pulmonary disease (COPD). Utilizing advanced technology and a multimodal approach, the study will assess the extent and nature of increased SNA, as well as the underlying mechanisms contributing to this phenomenon. Factors such as obstructive sleep apnea, inspiratory muscle dysfunction, pulmonary hypertension, and systemic inflammation will be evaluated to provide insights into their roles in COPD. The research is conducted at the RWTH Aachen University Hospital's respiratory and autonomic nervous system physiology laboratory.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and management of sympathetic nerve activity in COPD patients, potentially enhancing treatment strategies.
How similar studies have gone: While studies have explored sympathetic nerve activity in heart failure, this specific investigation in COPD is novel and has not been extensively tested.
