Summary

This trial will help researchers understand how the nervous system communicates with blood vessels to increase blood pressure during stress, and how hypertension and obesity may influence this process.

Who is the study for?
This trial is for adults aged 18-55 who are either healthy, overweight (BMI>30), have high blood pressure, or both. Participants must not have other significant cardiovascular diseases, kidney disease, a history of smoking, or diabetes.
What is being tested?
The study aims to understand how stress affects blood pressure in people with obesity and/or hypertension by measuring nervous system activity and blood flow during stress tests and drug-induced changes in vessel size.
What are the potential side effects?
Potential side effects may include reactions to the infusion such as discomfort at the injection site or allergic reactions. Stress tests might cause temporary increases in heart rate or blood pressure.
