A device to treat chest pain from small heart vessels
Part of Heart & circulation clinical trials.
This study tests a small metal device (called a coronary sinus reducer) that is placed in a vein of the heart to help people with ongoing chest pain caused by small blood vessel problems, which don't get better with standard medicines. It aims to improve blood flow and reduce pain.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You have had chest pain or other heart symptoms (like pressure, tightness, or shortness of breath) that have lasted for at least 30 days, despite taking medication.
- Your heart's pumping function (ejection fraction) is at least 25%.
- You do not have a main heart artery blockage that needs a stent or bypass surgery.
- You are willing to have a test to measure blood flow in your heart's small vessels (CFR) and to use a study app to track your symptoms.

This trial tests a device called the Coronary Sinus Reducer for people with chest pain caused by problems in the small arteries of the heart. The device is placed in a vein near the heart to improve blood flow and reduce symptoms.
This trial tests whether a small pressure-reducing device placed in a heart vein (the coronary sinus) can reduce symptoms in people with ongoing chest pain from tiny blood vessel problems. It is for angina that has not improved despite standard heart medicines, and only if special heart tests show reversible reduced blood flow.
This study looks at how to personalize treatment for people with angina (chest pain) by measuring how well blood flows through the heart’s small vessels and the main arteries during a procedure. It may help doctors choose the right approach after your coronary angiography (heart artery imaging).
This trial tests a device placed in a heart vein (the coronary sinus) to improve blood flow and reduce chest pain in people with coronary microvascular dysfunction (small blood vessel disease). It aims to help those who still have symptoms despite taking heart medications.
This study tests a device (Coronary Sinus Reducer) for people who still have chest pain despite medications and cannot have standard treatments like stents or bypass. It may help improve blood flow and reduce symptoms.
This trial tests a small device placed in a vein near the heart to improve blood flow and reduce chest pain in people who cannot have bypass surgery or stents. The device aims to increase the heart's oxygen supply and relieve symptoms.
