Freezing heart arteries to stabilize high-risk plaques
Part of Heart & circulation clinical trials.
This study tests a special cooling balloon to freeze and stabilize dangerous plaques in heart arteries that are not the main cause of your current symptoms. It aims to prevent future heart attacks.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old.
- You have chest pain due to stable angina or a recent heart attack (NSTEMI, unstable angina, or STEMI) and have already had a successful balloon/stent procedure on the main blocked artery.
- You have at least one additional high-risk plaque in another artery that is not fully blocked but has features like soft plaque or large size, and is between 30-70% narrow.
- The target plaque must be in a vessel that is between 2.5 mm and 3.75 mm wide, and not too long (under 20 mm).
- You have not had prior bypass heart surgery, severe kidney disease, severe heart valve disease, or a very low heart pumping function.

This study tests a special balloon that helps prepare hardened blockages in the heart's arteries for stenting. It might improve outcomes for people with heavily calcified plaque.
This study uses special imaging inside your heart arteries to find dangerous plaques that could cause future heart attacks. The goal is to help identify which blockages need treatment.
This trial tests two methods for breaking up heavy calcium buildup in heart arteries before placing a stent. It compares a specialized high-pressure balloon to a device that uses shockwaves.
This trial tests whether a balloon coated with medicine (drug-coated balloon) can prevent future heart attacks by treating high-risk plaques in arteries that are not the one that caused your current heart attack. You may qualify if you already had a stent placed and have another mildly blocked artery with certain vulnerable features.
This trial compares two ways to treat hardened (calcified) coronary arteries using a tiny rotating burr (rotational atherectomy) followed by either one of two balloon techniques to open the artery. It aims to see which method better prepares the artery for a stent, potentially improving blood flow and reducing complications.
This study is testing whether doing a heart procedure (like placing a stent) right away, in addition to taking medicines, is better than just taking medicines alone for people with narrowing and high-risk plaque in their heart arteries. The goal is to prevent future heart attacks.
