Check how the body’s stress nerve system works
Part of Brain & nervous system clinical trials.
This study measures “sympathetic nerve activity,” which is part of your body’s automatic stress-response system. It looks at how active that system is in people with certain conditions (or in healthy volunteers), which may help researchers understand symptoms and risks.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have one of these conditions: high blood pressure, heart failure, heart disease with clogged arteries, abnormal heart rhythms, cardiomyopathy, or pulmonary hypertension
- You may also qualify if you have COPD, sleep apnea, long-term lung blood clot history (pulmonary embolism), hepatitis or liver cirrhosis
- You may also qualify if you have hepatorenal syndrome, kidney failure, nephritis, or irritable bowel syndrome
- Or you can join as a healthy volunteer without these conditions
- You must not be pregnant

This study looks at how the body’s automatic “fight-or-flight” nerve system may relate to spontaneous coronary artery dissection (SCAD). If you have a SCAD history, your results may help researchers understand the condition better; if you’re a healthy control, your data are compared to SCAD patients.
This study looks at “sympathetic nerve activity” (signals from the nervous system that affect the heart) in adults with chronic obstructive pulmonary disease (COPD). The goal is to see whether these measurements can help predict what happens to people with COPD.
This study looks at how your body responds to stress, depending on how active you are. If you join, you'll help researchers understand how exercise affects the nervous system in young adults.
This study looks at how the body’s stress system works in veterans with PTSD compared with veterans without PTSD. You may be asked about blood pressure, lifestyle, and health conditions to see whether the study measures differences that could help future treatment.
This study compares two ways of measuring heart rate variability (a sign of how well your nervous system is working) during a gentle nerve stimulation therapy. It looks for healthy volunteers to see if a simple arm measurement works as well as a chest measurement.
This study looks at how the nervous system controls automatic body functions (like heart rate and blood pressure) in people with multiple sclerosis. Researchers want to compare results between people with MS and healthy volunteers to understand how MS affects these functions.
