This study tests a technique called acute normovolemic hemodilution (ANH) in 2000 high-risk heart surgery patients. Before the heart-lung machine is used, doctors remove some blood and replace it with fluids. The goal is to see if this reduces the number of patients who need a bl…

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 study follows 2000 people who have or will get the OmniaSecure defibrillation lead, a wire that helps control dangerous heart rhythms. Researchers will track how often the lead causes problems over 5 years. The goal is to make sure the lead is safe and works as expected in e…

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 trial tests whether a procedure called catheter ablation works better than anti-arrhythmic drugs for people with structural heart disease who have had a dangerous fast heart rhythm (ventricular tachycardia). About 162 participants will be randomly assigned to either ablation…

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 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 tests whether adding blood flow restriction (BFR) to standard resistance training helps heart rehab patients get stronger and healthier. Twenty adults with stable heart disease will do exercises with and without a special cuff that limits blood flow to the arms and leg…

This study tests whether a nerve block given before heart surgery can reduce pain and the need for opioid painkillers afterward. About 150 adults having heart surgery will receive either a long-acting or standard form of the numbing drug bupivacaine via ultrasound-guided injectio…

This study tests a short program that helps heart patients and their families explore what gives life meaning during cardiac rehab. About 80 people in Denmark will try one of three formats: one-on-one, with a relative, or in a group. The goal is to see if this approach can reduce…

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 compares three ways of delivering genetic counseling to adults with inherited heart conditions. Some participants get counseling before testing, others get it after, with or without a required phone call. The goal is to see which approach is most efficient and empoweri…

This registry follows 545 people with arrhythmia who received a heart ablation using the DiamondTemp system. Researchers will track how many stay free of their heart rhythm problem and how many have serious side effects over 12 months. The goal is to see how well the device works…

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 is a large registry that collects medical data and tissue samples from 30,000 people with heart disease and healthy volunteers. Researchers will analyze this information to better understand risk factors, treatments, and outcomes for various heart conditions. The goal …

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 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 …
