Recruiting studies
- NCT07314138Recruiting
Comparing two minimally invasive heart bypass surgeries for three-vessel disease
This trial compares two types of heart bypass surgery for people with blockages in three main heart arteries. It tests a hybrid approach that combines a small incision bypass with a stent, versus a standard off-pump bypass. This may mean less recovery time for some patients.
Leuven, Vlaams BrabantAges 18–85 - NCT07407738Recruiting
A trial of a shockwave device for calcified heart arteries
This trial tests a new device that uses sound waves to break up calcium deposits in heart arteries before placing a stent. It is for people with severely hardened arteries that are hard to treat with standard methods.
LyonAges 18 years+ - NCT06492733Recruiting
FastWire device for unblocking leg arteries (FREEFLOW trial)
This trial tests a new wire system to reopen completely blocked leg arteries without surgery. It is for people with severe leg pain or tissue damage caused by blocked arteries, and aims to restore blood flow and improve walking ability.
Wilmington, DelawareAges 18–85 - 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 - 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 - 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+ - 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+ - 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+ - 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+ - 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+ - NCT06985693Recruiting
AI-assisted stent placement study for heart disease
This trial tests whether a new artificial intelligence tool called Medipixel XA can help doctors place stents more precisely in blocked heart arteries. If you have coronary artery disease and need a stent, this study could be an option.
Gwangmyeong, Gyeonggi-doAges 19 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+ - 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 - NCT05829889Recruiting
FFR test versus angiogram to guide left main heart treatment
This trial compares two ways to decide how to treat a narrowed “left main” coronary artery: a pressure-based test (FFR) versus standard X-ray imaging (angiography). It aims to see which approach better helps choose safe, appropriate treatment using a stent when appropriate.
Hong KongAges 20 years+ - NCT05831085Recruiting
Compare procedures to improve heart blood flow in diabetes
This study compares two ways to restore blood flow to the heart—stent placement (PCI) versus bypass surgery (CABG)—in people with diabetes and significant multi-vessel coronary artery disease. It looks at outcomes using both standard heart tests and additional imaging/functional measurements to guide the best revascularization strategy.
Palo Alto, CaliforniaAges 20 years+ - NCT06075602Recruiting
Complex and calcified coronary artery disease: a registry study
This study watches how people with complex or calcified heart artery disease are treated (with stents or bypass surgery) and how they do over time. It aims to learn which treatments work best for tough blockages.
Lucerne, Canton of LucerneAges 18 years+ - NCT06137521Recruiting
Heart artery blockage study
This study looks at people with a long-standing complete blockage in a heart artery. The goal is to understand risk factors and outcomes, which may help guide future treatments.
ShanghaiAges 18 years+ - 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+ - NCT06373601Recruiting
Testing a drug-coated balloon for small heart arteries
This study tests a drug-coated balloon (DCB) that releases two medicines (sirolimus and paclitaxel) to open blocked small heart arteries. It may help people with stable chest pain or recent, controlled heart events who have a narrowed small vessel.
Mercogliano, Italy/AvellinoAges 18 years+ - 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+ - 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+ - 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 - NCT06567938Recruiting
Heart artery procedure study for people with kidney disease
This trial uses a special ultrasound camera inside the heart's arteries to guide stent placement for people with chronic kidney disease. The goal is to see if this approach improves outcomes compared to standard methods.
Xi'an, ShaanxiAges 18 years+ - NCT06606821RecruitingPhase 4
Tirzepatide for heart health in people with overweight or obesity
This trial tests the weight‑loss medication tirzepatide (Mounjaro) in people who are overweight or have obesity and have stable coronary artery disease. The goal is to see if tirzepatide can reduce dangerous fatty plaque in heart arteries.
