This research study is looking at how the smallest blood vessels in the heart work differently in men versus women. You'll have chest pain symptoms but normal-looking coronary arteries (the main heart blood vessels). The study uses a special heart imaging test with medication to measure how well blood flows through your heart's tiny vessels.
Many patients have chest pain even though their main heart arteries look normal on standard tests. Doctors think the problem may be in the smaller blood vessels that branch off from the main arteries. This study wants to understand whether men and women have different patterns of this small-vessel dysfunction, which could help doctors diagnose and treat the condition better.

You will receive an injection of adenosine (a medication that temporarily increases blood flow to your heart) while a special ultrasound machine takes images of your heart. The researchers will measure your heart's blood flow at different time points after the adenosine injection. The study involves one main visit where these heart imaging measurements are performed, and you'll be monitored throughout the procedure for safety.
