A device to reduce chest pain when other treatments are not possible
Part of Heart & circulation, Pain clinical trials.
This trial tests a small device called a coronary sinus reducer that is placed in a vein of the heart to improve blood flow and reduce chest pain in people who still have angina despite medications and cannot have stents or bypass surgery. The procedure is done through a small tube in the groin or arm.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have chest pain (angina) that limits your daily activities despite trying at least two different heart medications.
- Your heart doctor has determined that standard procedures like stents or bypass surgery are not safe or not possible for you.
- You have a specific blockage in a major heart artery that can be measured with a pressure wire.
- You are willing to use a smartphone app to record your symptoms for two weeks before the procedure.
- You are not pregnant, do not have severe heart failure, severe lung problems, or kidney failure, and have not had a recent heart attack or stent procedure.

Other trials that look related to this one.
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 whether giving a drug called nicorandil directly into the heart artery just before placing a stent can help keep blood flow normal and reduce complications after the procedure.
This trial is testing a new way to measure blood flow in the heart during exercise to better understand angina. You may be eligible if you have at least two blocked heart arteries and are scheduled for stent placement.
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 study compares two ways to open blocked heart arteries: one uses a balloon coated with medicine, and the other uses a small mesh tube (stent) that releases medicine. The goal is to see which works better for people with chest pain or a recent heart attack.
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.
