Data collection for branched aortic stent grafts
This trial collects follow-up data from patients who received special branched stent grafts (tube-like devices) to treat complex aortic aneurysms (weakened areas of the main blood vessel). The study helps confirm these devices work safely over time.

Study of orforglipron for heart and kidney health.
This trial tests if orforglipron can reduce the risk of heart attack, stroke, or kidney failure in people with heart disease or chronic kidney disease.
Bahía BlancaAges 50 years+ - NCT06863155Recruiting
A thin heart stent for people on blood thinners
This trial tests a new type of heart stent in people who also take daily blood thinners. The stent is very thin and releases medicine over time to help keep the artery open, and the coating eventually dissolves. It may be a safer option for people on blood thinners who need a stent.
AlbaceteAges 18 years+ - NCT07343297Recruiting
Ask questions about clinical trials
This study helps people learn about clinical trials and find out if they might be a good fit. It is for patients who are already getting treatment at a Karmanos or McLaren center and can read English well enough to complete surveys.

Effect of Leg Artery Blockage Treatment on Blood Pressure
This study looks at how treating blocked arteries in the lower belly and groin area affects blood pressure. If you have a long blockage in your main artery or the arteries to your legs that causes pain or trouble walking, this trial may help understand if treatment improves your blood pressure.
ArnhemAges 18 years+ - NCT07082712Recruiting
Thyroid issues and heart attack link study
This study looks at whether thyroid problems are connected to heart attacks (acute coronary syndrome). It may help explain why some people have heart issues.
SohagAges 20 years+ - NCT07044154Recruiting
Sun Tai Chi for heart, lung, and mental health in college students
This trial tests whether a gentle Sun-style Tai Chi program can improve your heart and lung fitness as well as your mental well-being if you have mild to moderate stress, anxiety, or depression. It's for university students who are not already very active and who are not taking mental health medicines.
Talca, Maule RegionAges 18–29 - NCT07038083Recruiting
Heart and metabolic health tracking study
This study aims to track real-world data on heart and metabolic health protection. It includes people 18 years or older with conditions like high blood pressure, diabetes, obesity, abnormal cholesterol, or high uric acid.
Guangzhou, GuangdongAges 18 years+ - NCT07069491Recruiting
High blood pressure during dialysis: what causes it?
This study is looking at why some people develop high blood pressure during their dialysis sessions. Your participation could help doctors better manage this condition in the future.
SohagAges 18–70 - NCT07072026Recruiting
Opening blocked arteries in the brain long after stroke
This trial looks back at patients who had a procedure to reopen a major artery in the brain that had been blocked for a long time. It will help doctors learn if this treatment is safe and effective for people with chronic blockages in certain key arteries.
EssenAges 18 years+ - NCT07000175Recruiting
Heart rate measurement on arm vs. chest during nerve stimulation
This study compares two ways of measuring heart rate variability (a sign of how well your nervous system is working) during a gentle nerve stimulation therapy. It looks for healthy volunteers to see if a simple arm measurement works as well as a chest measurement.
Trabzon, OrtahisarAges 18–45 - 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 - NCT07043920Recruiting

VALVE-AI: A study of heart valve health
This trial is testing a new way to check for heart valve problems using your recent ECG (heart electrical test). If you're 60 to 85 and haven't had recent heart imaging or known valve disease, you may qualify.
TaipeiAges 60–85 - NCT06916520RecruitingPhase 4
Reduced dose prasugrel alone after stent placement
This trial tests if a lower dose of prasugrel, taken alone (without aspirin), is safe and works well for people who have had a stent placed for chest pain or a heart attack. It might be an option for those who need to simplify their medication routine.
AmsterdamAges 18 years+ - NCT06971718Recruiting
Study of blood flow in branched heart arteries
This trial tests a new way to measure blood flow in heart arteries that branch. It may help doctors decide the best treatment for blockages where one artery splits into two.

Choosing the right size balloon pump with CT scans and X-rays
This study looks at how measurements from CT scans and X-rays can help doctors pick the right size of a special heart pump (called an intra-aortic balloon pump) that is placed in your main artery. It uses information from tests you may already have had.
Bangkok Noi, BangkokAges 18 years+ - NCT06958016Recruiting
