Testing heart artery causes of pain without major blockage
Part of Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been referred for an elective heart angiogram because doctors suspect reduced blood flow to the heart
- You have symptoms like angina (chest pain or pressure) or similar discomfort with activity or emotional stress, or at certain times
- You are not having an emergency heart problem right now (like STEMI/NSTEMI) and you’re not in shock
- You’re not scheduled mainly as an “asymptomatic” pre-procedure check, and you haven’t had a heart transplant
- Your kidneys are functioning adequately (creatinine is not above 1.5)
- You can give informed consent, and you can communicate for the consent process in the allowed languages

Other trials that look related to this one.
This trial tests whether using a special heart CT scan (with blood-flow analysis) can better guide care for people who come to the ER with chest pain and are at medium risk for heart problems. It might help avoid unnecessary procedures and find real blockages sooner.
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 study compares two ways of testing the small blood vessels in the heart to understand chest pain when no major blockages are found. It may help doctors learn more about why you have chest pain and how to treat it.
This study looks at why some people have chest pain or other heart symptoms even when their main heart arteries are not blocked. It tests whether inflammation in the small blood vessels of the heart might cause these symptoms, and aims to understand how to better diagnose and treat this 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.
This study tests a new way to find which blocked heart arteries are causing your chest pain. During a stent procedure, doctors will briefly block each artery to see which one triggers your symptoms. This might help them decide which blockages to treat.
