This Phase 3 study tests a weekly injection called retatrutide in about 1,946 people with severe obesity (BMI ≥35) and established heart disease. The goal is to see if it helps with weight loss and improves heart-related health measures over 113 weeks compared to a placebo. Parti…

This study tests whether a weekly injection of CagriSema (a combination of two drugs) can reduce the risk of heart attacks, strokes, and other heart-related events in people with established cardiovascular disease. About 7,100 participants will receive either CagriSema or a place…

This phase 3 trial tests whether a monthly injection of pelacarsen can reduce major heart problems like heart attacks and strokes in people with high levels of Lp(a), a genetic risk factor. Over 8,000 participants with existing heart disease are being followed for several years. …

This large study is testing whether a lower blood pressure target can reduce major heart problems like heart attacks, strokes, and heart failure in people with type 2 diabetes. About 9,500 participants with high blood pressure and high cardiovascular risk are being randomly assig…

This study tests whether giving patients capsules containing gut bacteria (called Probacine) before and after heart surgery can reduce gut injury and organ failure. Researchers will enroll 500 adults undergoing cardiovascular surgery. The goal is to see if changing the gut microb…

This program allows individual patients with vascular disease or end-stage kidney disease on dialysis to request an experimental lab-grown blood vessel (ATEV) if they have no other treatment options and cannot join a clinical study. The vessel is designed to replace or bypass dam…

This study tests a laser-based imaging method that shows blood flow in the brain in real time during surgery. It involves 20 adults having brain surgery for conditions like aneurysms. The goal is to see if this technique can give surgeons continuous feedback, unlike the current d…

This study tests whether an AI tool can help radiologists read brain CT and MRI scans more accurately and quickly. Researchers will compare how well doctors, AI alone, and doctors using AI together can spot abnormalities, urgent findings, and classify diseases. The goal is to red…

This study explores whether a simple, non-invasive leg movement test can measure blood vessel health in older adults. Researchers will use ultrasound to track blood flow changes after a passive leg movement, comparing young healthy people and older patients undergoing heart tests…

This large study tested whether taking daily vitamin D3 and omega-3 (fish oil) supplements can lower the risk of developing cancer, heart disease, or stroke. Over 25,000 healthy older adults (men 50+, women 55+) took the supplements or placebos for about 5 years. The goal is to s…

This study tests a nurse-led education program designed to help women in cardiac rehab address sexual concerns after a heart event. Sixty-six women will be randomly assigned to either the program or usual care. The goal is to see if the program improves sexual function, mood, and…

This study tracks 120 adults with heart disease and at least two other long-term illnesses to see how often dangerous drug interactions happen. Researchers check medications, including over-the-counter and herbal products, and follow participants for a year. The goal is to unders…

This study tracks over 1,700 heart patients who had hip or knee replacement surgery. Researchers want to see how often bleeding or blood clots happen in the months after surgery. The goal is to find better ways to prevent these complications.

This study will observe 200,000 Chinese adults with heart disease to see how their heart and lung function changes over 5 years. Participants will take a special exercise test to measure their fitness. Researchers hope to find better ways to predict future heart problems like hea…

This study follows 2000 people with dilated cardiomyopathy (a weakened, enlarged heart) over several years to learn how genetics and heart scarring affect the disease. Participants give blood for genetic testing and have heart MRI scans. The goal is to improve diagnosis and pave …

This study planned to compare virtual clinic visits (using video calls on tablets) with in-person visits for people with vascular diseases. Doctors would classify patients as low, moderate, or high risk for treatment after each visit type. The goal was to see if virtual visits co…

This study looks at how being in a hospital intensive care unit (ICU) after heart surgery affects your body's natural sleep-wake cycle. Researchers will track sleep patterns and thinking ability in 15 adults to see if disrupted rhythms slow down recovery. The goal is to understan…

This study aimed to see if using a special pad along with a standard closure device could help patients get out of bed sooner after a heart catheterization. It was planned for adults having the procedure through the groin. However, the study was withdrawn before any participants …

This study follows 347 heart surgery patients to understand why some develop swallowing problems (dysphagia). Researchers will use special camera tests to watch how patients swallow and look for risk factors. The goal is to create simple tools that doctors can use at the bedside …

This study is following 10,000 adults who are having a heart MRI for medical reasons. Researchers want to see if the MRI results can help predict who will have heart problems in the future, like heart attacks or heart failure. The goal is to better understand how MRI scans can gu…

This study aimed to create a 12-month profile of patients admitted for vascular surgery at University Hospital Limerick in Ireland. The goal was to understand patient characteristics like frailty and other health conditions to improve hospital services and reduce length of stay. …

This study gathers MRI, CT, and ultrasound images from 300 adults—some healthy, some with kidney or brain disease—to build a collection for future not-for-profit research. No new treatments are being tested; the goal is to make medical images available to scientists for advancing…
