Recruiting studies
- NCT07020858Recruiting
FAPI imaging for heart attack risk in blocked arteries
This trial tests whether a special scan called FAPI-PET can predict heart problems in people with a chronic total occlusion (a completely blocked heart artery for at least 3 months). If you have this type of blockage and are planning to have a procedure to open it, this study may help guide your care.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06890312Recruiting
Timing of blood thinner during heart catheterization
This study looks at the best time to give a standard blood thinner (heparin) during a heart procedure called angioplasty, which opens blocked heart arteries through a wrist artery. It may help reduce bleeding or clotting risks.
Strasbourg, Bas-RhinAges 18 years+ - NCT06535568Recruiting
Comparing one vs two blood thinners after heart artery balloon treatment
This trial tests whether taking just one blood thinner (clopidogrel) is as safe and effective as taking two (clopidogrel plus aspirin) for older adults or people at high bleeding risk who have had a drug-coated balloon procedure to open blocked heart arteries.
Milan, MIAges Any age - NCT02061436Recruiting
Chronic total occlusion procedure registry
This study collects data from patients who are having a procedure to open a completely blocked coronary artery. It may help improve future treatments for this condition.
Phoenix, ArizonaAges Any age - NCT07053254Recruiting
Studying vein grafts in older heart bypass patients
This trial looks at how vein grafts work in older adults who need coronary artery bypass surgery. It aims to understand why grafts sometimes fail, so doctors can improve treatment.
SeoulAges 19–100 - NCT01889459Recruiting
Registry after stent procedure for blocked heart arteries
This study follows people who had a stent placed for a long-standing blockage in a heart artery (called a CTO). It’s mainly a “registry” to understand outcomes after these procedures and help improve care in the future.
KurashikiAges 20 years+ - NCT06414551Recruiting
Calcium on CT scan and heart blockage procedure outcomes
This study looks at whether calcium buildup seen on a heart CT scan affects the success of opening a completely blocked artery. It may help guide future treatment for people with similar blockages.
Birmingham, West MidlandsAges 18 years+ - NCT05230446Recruiting
Testing full stent treatment for heart artery blockages
This study looks at how well doctors can treat multiple blocked heart arteries using a specific drug-eluting stent, aiming to fully open them. It may help patients whose blockage pattern fits the study, but it does not include certain high-risk or special cases.
Rotterdam, South HollandAges 18–85 - NCT07286578Recruiting
Using heart CT scans to guide treatment for blocked arteries
This trial is testing whether a special heart CT scan (coronary CT angiography) can help doctors better understand and treat calcium buildup in your heart arteries. If you have a type of heart disease that might need a stent or other procedure, this study could help decide the best approach.
Boston, MassachusettsAges 18–85 - NCT06400290Recruiting
Balloon test to find which artery causes chest pain
This study tests a new way to find which blocked heart arteries are causing your chest pain. During a stent procedure, doctors will briefly block each artery to see which one triggers your symptoms. This might help them decide which blockages to treat.
BasildonAges 18 years+ - NCT05490238Recruiting
Wrist vs arm access for complex heart procedures
This study compares using the wrist (radial artery) versus a different access site (conventional radial access approach) during complex, larger “bore” heart procedures to open blocked coronary arteries. It aims to see which approach is safer and works better for challenging cases like chronic blockages or heavily calcified arteries.
ArlonAges 18 years+ - NCT05411445Recruiting
Study blood markers in blocked grafts after bypass surgery
This study looks at small particles in your blood to understand why bypass grafts can become blocked after coronary bypass surgery. It may help doctors better monitor and treat this complication by relating blood markers to what happens after surgery.
Cotignola, RavennaAges 40–80 - NCT06567249Recruiting
Cooling the heart during a heart attack procedure
This study tests whether cooling the heart with a cold liquid during a procedure (angioplasty) can help reduce damage after a heart attack. It may be an option for people who arrive at the hospital quickly after a heart attack.
TomskAges 18–90 - NCT07369765Recruiting
Balloon vs stent for blocked arteries
This trial compares two procedures to open completely blocked coronary arteries: a drug-coated balloon or a drug-eluting stent. It may help patients with a single, medium-length blockage in a large enough artery.
IstanbulAges Any age - NCT07258290Recruiting
Freesolve Magnesium Scaffold for Heart Artery Blockages
This trial tests a new dissolvable magnesium scaffold to treat blockages in heart arteries. It is designed for people with stable heart pain or certain recent heart attacks, and it aims to open blocked arteries and then slowly dissolve over time.
Washington D.C., District of ColumbiaAges 18–80 - NCT07077057Recruiting
AI tool for heart attack detection
This trial tests an artificial intelligence system that helps doctors quickly identify heart attacks (myocardial infarction) in patients with symptoms like chest pain or shortness of breath. It aims to speed up diagnosis and treatment.
Lugano, Canton TicinoAges 18 years+ - NCT07614386Recruiting
Radial artery access outcomes in heart and vessel procedures
This registry collects data from patients undergoing heart or blood vessel procedures using a small artery in the wrist (radial or ulnar artery) for access. Researchers track outcomes to better understand the safety and effectiveness of this approach.
Mersin, MezitliAges 18 years+ - NCT07620119Recruiting
AI-assisted heart attack diagnosis in patients with LBBB
This study tests whether artificial intelligence can help doctors more accurately diagnose heart attacks in patients who have a specific heart rhythm pattern called Left Bundle Branch Block (LBBB). The goal is to improve emergency care by reducing delays in identifying who needs urgent treatment.
Konya, KaratayAges 18 years+ - NCT03428048Recruiting
NEXUS Registry for coronary artery disease or Afib patients
This is a research registry that collects health information about people with coronary artery disease or Afib. It may help doctors and researchers better understand these heart conditions and improve future care.
Glenwood Springs, ColoradoAges 18 years+ - NCT06857838Recruiting
Bypass surgery for symptomatic myocardial bridge
This trial tests whether bypass surgery is effective for people with a myocardial bridge (a heart muscle that arches over an artery) that still causes symptoms despite medication. It aims to see if surgery can improve symptoms and outcomes.
Xi'an, ShaanxiAges 18–80

Common questions
- Are there clinical trials for coronary occlusion?
- Yes. Clin2 currently lists 44 recruiting coronary occlusion studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a coronary occlusion trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a coronary occlusion trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
