Beijing, Beijing MunicipalityAges 18–80 - NCT06275386Recruiting
Drug-coated balloon for chronic heart artery blockages
This trial tests whether a special balloon coated with medicine (drug-coated balloon) can safely open a completely blocked heart artery, instead of using a permanent stent. It may be an option for people who have chronic chest pain or shortness of breath due to a long-standing blockage.
Warsaw, Masovian VoivodeshipAges 18 years+ - NCT04595630Recruiting
Testing heart blood markers to spot early bypass blockage
This study checks whether heart blood tests can predict early blockage of a coronary bypass graft soon after bypass surgery. It may help doctors identify patients at higher risk sooner so they can monitor or treat problems earlier.
ZagrebAges 18 years+ - NCT04549896Recruiting
CT scan study for complex blocked heart artery procedures
This trial studies how a CT scan may help plan a procedure to open a long-standing blocked coronary artery (a chronic total occlusion). It is aimed at people with complex, difficult blockages and symptoms or heart test results showing parts of the heart may still be alive.
OllioulesAges 18–90 - NCT03588481Recruiting
Check DeSyne X2 coronary stent in a heart registry
This study adds people to a registry to track outcomes after getting a specific heart stent called DeSyne X2. It may help doctors understand how well this stent works and how it affects recovery over time.
IncheonAges 19 years+ - NCT03756870Recruiting
Stent procedure vs best medical care for blocked heart arteries
This trial studies whether opening a completely blocked heart artery (a CTO) with a procedure and stent helps reduce areas of low blood flow in the heart, compared with the best medicines alone. It uses heart scans to find people likely to benefit and then checks results again at 6 months.
AmsterdamAges 18 years+ - NCT06957613Recruiting
A Registry for Chronic Total Heart Artery Blockages
This study is collecting information on people who have a complete blockage in a heart artery (a chronic total occlusion) and who are scheduled for a procedure to open it up. The goal is to learn more about the treatment and outcomes for these patients.
Bad Segeberg, Schleswig-HolsteinAges 18–100 - NCT07013344Recruiting
Link between NT-proBNP and heart artery disease
This study looks at a blood test called NT-proBNP to see if it can help predict how much blockage is in the heart's arteries. It may help doctors better understand heart disease risk.
Milan, ItalyAges 18 years+ - NCT06878729Recruiting
Comparing two ways to open a blocked heart artery
This trial tests two procedures—antegrade dissection/re-entry and the retrograde method—to treat a completely blocked artery. It compares which technique works better for patients with complex blockages.
Warsaw, WarsawAges 18 years+ - NCT06542393RecruitingPhase 2
Blood management for anemic patients having bypass surgery
This trial tests a blood management strategy to help people with anemia who are having coronary artery bypass surgery (CABG). If you qualify, you may receive a treatment to improve your blood counts before surgery, which could reduce the need for transfusions.
São Paulo, São PauloAges 18–80 - NCT06193954Recruiting
Vibrating guidewire for chronic heart artery blockages
This trial tests a special vibrating guidewire to help open heart arteries that have been completely blocked for a long time, when standard wires have failed. It may help you if you have a stubborn blockage requiring a gentle approach.
Atlanta, GeorgiaAges 18 years+ - NCT03667196Recruiting
Test opening blocked heart arteries using two different procedures
This trial studies whether two ways of threading a device to open a long-term blocked coronary artery are both safe and effective. You may qualify if you have a chronic total blockage and heart-related symptoms, and you can follow the study follow-up plan.
AnyangAges 19 years+ - NCT07380399Recruiting
Using the ulnar artery for heart tests when the radial artery is blocked
This trial looks at using the ulnar artery in the wrist instead of the radial artery for heart catheterization or stent placement, when the radial artery on that side is blocked. It may be an option for people who cannot use the other arm's radial artery.
AthensAges 18 years+ - NCT05078814Recruiting
Survey of a heart and leg condition’s gene differences
This study collects information to understand how often certain genetic variants (ALDH gene family) show up in people with blocked leg arteries or an acute heart condition. The results may help researchers better understand the biology behind these illnesses.
TainanAges 20 years+ - NCT06910436Recruiting
AI timing and outcomes in heart attack study
This trial uses artificial intelligence to analyze ECG results and timing in patients with a type of heart attack called Non-STEMI (where the artery is narrowed but not fully blocked). The goal is to see if AI can help predict damage and outcomes, which could lead to better care.
Bolzano, BZAges 18 years+ - NCT06795763Enrolling by invitation
New imaging & catheter system for blocked heart arteries
This trial tests a new imaging and catheter system to treat chronic total blockages in heart arteries. If you still have chest pain or other symptoms despite medical therapy, this study may help open the blockage and improve blood flow.
Atlanta, GeorgiaAges 18 years+ - NCT06542653Recruiting
PCI for chronic heart artery blockages
This trial looks at how a procedure to open a long-clogged heart artery (called PCI) affects patients' long-term health. If you have had a complete blockage in a heart artery but no recent major heart attack, bypass surgery, or cancer, you may be able to join.
Nanjing, JiangsuAges 18–75 - NCT02352818Recruiting
Chronic heart artery blockage registry for treatment outcomes
This study is a registry that collects information about people who try to reopen a long-term blocked heart artery. It doesn’t test a new treatment—your doctors use standard care, and the registry helps learn what happens over time.
LeuvenAges 18 years+ - NCT03563417Recruiting
CTO treatment vs medicines after heart scan
This trial studies whether opening a blocked coronary artery (a CTO) helps people more than staying on the best available heart medicines after an initial 3-month treatment period. It uses heart imaging to confirm there is reduced blood flow in the area supplied by the blockage.
Aarhus NAges 18 years+ - NCT04944615Recruiting
IVUS-guided stent placement for blocked heart artery using longer guidance
This trial compares two ways to place a stent (a small mesh tube) for a completely blocked heart artery: using an IVUS camera inside the artery versus using a standard x-ray approach. It may help people get better heart outcomes by improving how accurately the stent is placed in long-term blockages.
BeijingAges 18 years+ - NCT07114393Recruiting
Better imaging to guide complex heart artery procedures
This study looks at whether using advanced imaging inside the heart arteries during complex procedures leads to better outcomes compared to current standard practice. If you have had a complex angioplasty (PCI) and your data is in a national heart registry, you may be included.
