Summary
The goal of this clinical trial is to learn whether beta-blockers can improve coronary blood flow and reduce resistance in patients with angina and no obstructive coronary arteries (ANOCA).
The main questions it aims to answer are:
* Do beta-blockers improve coronary blood flow in patients with ANOCA?
* Do beta-blockers reduce coronary microvascular resistance in these patients?
Researchers will compare a beta-blocker to a placebo to see if the medication has measurable effects on coronary circulation.
Participants will:
* Receive a beta-blocker or a placebo
* Undergo specialized heart tests (such as coronary flow and resistance measurements) before and after treatment.
