Heart angle test for coronary artery blockages
Part of Heart & circulation clinical trials.
This study looks at how a specific heart rhythm measurement relates to the presence of extra blood vessels that form around a completely blocked artery. It may help doctors understand how well the heart is compensating for blockages.
Summary written for real people, not researchers, by Clin2.

This trial tests if a cardiac rehab exercise program can help patients with a completely blocked heart artery before they get a stent procedure. It aims to see if the program is safe and doable for these patients.
This trial tests a procedure for people with a completely blocked heart artery that has been present for at least 3 months. It aims to see if opening the blockage can improve blood flow and heart function.
This study is a registry that collects information from people who are having a procedure to open a completely blocked heart artery. It helps doctors learn more about these procedures and how to improve care for people like you.
This study looks at people with a long-standing complete blockage in a heart artery. The goal is to understand risk factors and outcomes, which may help guide future treatments.
This trial looks at people with a blockage in a heart artery of 50% or more. It tests a new way to check the blockage using a special CT scan. This could help decide the best treatment to prevent future heart problems.
This trial studies whether two ways of threading a device to open a long-term blocked coronary artery are both safe and effective. You may qualify if you have a chronic total blockage and heart-related symptoms, and you can follow the study follow-up plan.
