A heart vein implant for persistent chest pain
Part of Heart & circulation, Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have chest pain (Canadian class II-IV) despite taking at least two heart medications.
- You have a significant blockage in the left main artery (LAD) that cannot be treated with stents or bypass surgery.
- You are willing to track symptoms using a smartphone app for 2 weeks before the procedure.
- You are not pregnant, do not have severe lung disease, and have good kidney function.
- You have not had a heart attack or stent placement in the last 3 months.
- You do not have severe heart failure or certain arrhythmias.

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 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 study tests a detailed diagnostic procedure during heart catheterization for patients who previously had stents placed and now have chest pain or signs of heart stress. The goal is to better understand blood flow in treated arteries to guide treatment decisions.
This trial tests a new device called the VentriCure that helps the heart pump blood. It is for people with severe coronary artery disease and a weak heart who cannot have bypass surgery or choose not to.
This trial tests a new gene therapy (XC001) delivered through a thin tube into your heart's blood vessels. It aims to grow new blood vessels to relieve chest pain in people with chronic angina who have no other treatment options.
This study looks at treatment options for adults with significantly reduced heart pumping strength and extensive coronary artery disease. It may help people who are at higher risk due to widespread blocked heart arteries, but eligibility depends on recent heart events and bleeding risk.
