Heart sinus reducer for chest pain from small vessel disease
Part of Heart & circulation, Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 or older.
- You have had chest pain (or similar symptoms) for at least 30 days, despite taking at least 2 heart medications or the maximum you can tolerate.
- Your heart's pumping strength (LVEF) must be 25% or more (measured within the last year).
- You must have a special test result (CFR less than 2.5) showing reduced blood flow in the small heart vessels.
- You must be willing to have the device implanted and follow up with study visits.

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.
This trial tests a device placed in a heart vein to improve symptoms in people whose heart pumps normally but still causes shortness of breath and fatigue. The device may help relieve pressure in the heart and improve daily life.
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 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 study tests a device called the sinus reducer for people with long-lasting chest pain that hasn't improved with medication or other procedures. It may help if you have limited options for treatment.
This trial tests a special device placed in a vein of the heart to help patients who have chest pain (angina) but no major blockages in their heart arteries. It is designed for people who have tried maximum medications but still have symptoms.
