Targeted medicines for chest pain without blocked arteries
Treatments studied
Part of Heart & circulation, Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have chest pain (stable angina) and are being scheduled for tests in the heart catheterization lab.
- Angiogram shows no large blockages in the heart arteries, and a special pressure test (FFR) is greater than 0.80.
- You have at least one of: spasm in the large arteries or small vessels, reduced blood flow reserve, high microvascular resistance, or a heart muscle bridge with low pressure.
- You have not had a heart attack or unstable angina in the past week, and do not have a weakened heart muscle (cardiomyopathy).
- Your blood pressure is at least 95 mmHg (top number) and your resting heart rate is at least 55 beats per minute.

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 study looks at people who have chest pain but don't have major blockages in their heart arteries. It aims to understand how the tiny blood vessels and artery spasms might be causing symptoms, using special heart tests.
This study looks at people who are being checked for possible heart artery–related chest or similar discomfort, but without major artery blockage (non-obstructive arteries). It aims to help doctors understand what might be causing symptoms and guide safer testing.
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.
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 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.
