Beta-blockers for chest pain without blocked arteries
Part of Heart & circulation, Pain clinical trials.
This trial tests if beta-blocker medication improves blood flow and reduces resistance in the tiny blood vessels of the heart in people who have chest pain but no major blockages in their arteries.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are having a cardiac catheterization (angiogram) to check for chest pain.
- Your main heart arteries are not significantly blocked (less than 50% narrowing).
- Blood flow in your arteries appears normal on the angiogram.
- Your heart rate and blood pressure are stable and not too low.
- You do not have heart failure or severe valve disease.
- You have not had bypass surgery.

This trial tests if the medicine nebivolol can help people with stable chest pain caused by small heart vessel problems, not blocked arteries. You may qualify if you have regular chest pain, normal main arteries, and abnormal small vessel function tests.
This study tests if specific heart medicines (like beta-blockers or calcium channel blockers) can help people with chest pain that is not caused by blocked arteries. It aims to treat the tiny blood vessels or spasms that may be the real cause of your pain.
This trial tests a heart medication (a cardio-selective beta-blocker) given during a heart attack to see if it reduces damage to the heart muscle. It might help people having their first heart attack who are treated quickly with angioplasty (a procedure to open blocked arteries).
This study tests a non-invasive method to evaluate chest pain in people who do not have blocked coronary arteries. It may help patients understand the cause of their symptoms without needing invasive procedures.
This study helps women with chest pain or heart symptoms who have normal-looking coronary arteries (the blood vessels that feed the heart). Researchers will perform specialized heart tests to understand why you have symptoms, then tailor treatment based on your specific condition.
This trial studies people who have chest pain (angina) due to problems with the heart’s small arteries, not a big blockage. It aims to test whether treatment approaches can help these patients by better understanding the cause of their heart-related symptoms.
