The study focuses on Coronary Microvascular Dysfunction (CMD), a heart issue affecting small blood vessels in women, causing chest pain. CMD can lead to serious heart problems. This research aims to understand if stress affects women with CMD differently than others. The Autonomic Nervous System (ANS), which controls heart rate and breathing, is also studied. Participants will undergo various tests, including stress and exercise tests, to see how stress impacts their heart and blood vessels. Data collected might help find better treatments for CMD.

• The study involves physical exams, stress tests, and surveys.
• Participants will monitor their mood and stress at home for a week.
• Researchers will save data and samples for future studies.
