MYOCARDIAL INFARCTION

This study compares two ways to decide which blocked arteries to stent in heart attack patients who have multiple blockages. One method uses standard X-ray images; the other uses a computer analysis of those images to measure blood flow. About 1,800 patients will be randomly assi…

This study looks at two ways to treat heart attacks in people aged 75 and older who have several blocked heart arteries. One approach only fixes the artery that caused the heart attack, while the other uses a special test to decide which other blockages to open. The goal is to se…

This early study tests a new freezing treatment for people who recently had a heart attack or unstable chest pain. The treatment uses a special balloon to freeze high-risk plaque in the heart's arteries that could rupture and cause another heart attack. The goal is to stabilize t…

This study is testing whether daily shakes made from bilberries and oats can lower LDL cholesterol and improve exercise capacity in people who have had a heart attack or have type 2 diabetes. 900 participants will drink either a bilberry shake, an oat shake, a combination shake, …

This study follows over 1,000 people who had a heart attack and received a stent. Researchers want to see if a supervised exercise program lasting at least 1.5 months can reduce the risk of future heart problems, stroke, or death. The goal is to find out whether regular, moderate…

This study tests whether a web-based program, including activity tracking, blood pressure monitoring, and educational modules, can help people who have had a heart attack avoid future heart problems. About 864 participants will either use the program or receive standard care. Som…

This study tracks over 1,300 heart attack patients who received a procedure called percutaneous coronary intervention (PCI), which opens blocked heart arteries. Researchers want to see if PCI reduces major heart problems like death, another heart attack, or the need for more proc…

This study compares two methods of prescribing high-intensity interval training (HIIT) for people in cardiac rehabilitation. Thirty adults with heart conditions will follow a 12-week exercise program to see which prescription approach improves fitness, heart function, and oxygen …

This study compares two types of drug-coated stents (SYNERGY and BioMatrix NeoFlex) in 160 patients with coronary artery disease. Researchers use a special camera to check how well the stents heal inside the artery at 1 and 3 months after placement. The goal is to see which stent…

This study tests whether giving evolocumab, a powerful cholesterol-lowering drug, very early during a heart attack hospital stay can reduce the chance of another heart attack, stroke, or death. About 6,000 adults hospitalized for a heart attack are randomly assigned to receive ev…

This study tests a new PET heart scan that uses 100 times less radiation than current methods. Researchers will scan 200 adults with known or suspected heart artery disease to see if the ultra-low dose still produces clear images. The goal is to make heart imaging safer while kee…

This study is testing whether a special heart scan (dynamic SPECT) can accurately detect remaining blockages in heart arteries after a heart attack, compared to the current standard invasive procedure (FFR). Sixty adults with multiple blocked arteries will receive both tests one …

This study tests a new way to classify heart attacks based on whether a coronary artery is fully blocked (occlusion) or not, instead of the traditional ST-elevation vs non-ST-elevation method. Researchers will compare outcomes in 6,000 patients to see if the new approach leads to…

This study tests whether a virtual world-based cardiac rehabilitation program is feasible for heart patients. Five participants will attend 24 online sessions over 8 weeks, including video visits with exercise physiologists and nurse coaches, plus group education. The goal is to …

This study looks at whether a new screening system can help doctors find heart complications early in high-risk patients after noncardiac surgery. Researchers will track 900 patients to see how well the screening works in practice and what it costs. The goal is to gather informat…

This study is a large international registry that will collect data from up to 130,000 people who have had a heart attack or unstable chest pain. Researchers will track treatments, outcomes, and safety to understand what works best in real-world care. No new drugs or devices are …

This study looks at 2,000 people who had a heart attack to see if checking the stiffness of their blood vessels one month later can help predict future heart failure, another heart attack, or bleeding. Researchers will track participants for several years to identify which measur…

This study looks at 450 people who had a heart attack but no major blockages in their heart arteries (called MINOCA). Using advanced imaging, researchers aim to find the real cause, such as plaque disruption or artery tears. Participants are followed every 6 months for up to 10 y…

This study tests whether a smartphone app that analyzes your voice can spot signs of depression and anxiety in people recovering from a heart attack. About 200 adults in cardiac rehab will use the app alongside their usual care. The goal is to see if voice analysis can help impro…

This study follows 1,599 people who had a first heart attack to see how their hearts remodel over time. Researchers want to link these changes to later heart failure. Participants are from several Minnesota counties and will be monitored for heart failure and death. No new drug o…

This study follows about 3,000 adults in Port-au-Prince, Haiti, to learn how common heart disease risk factors like high blood pressure, diabetes, and smoking are, and how they lead to heart attacks, strokes, and other heart problems. Researchers will track participants for about…

This study followed over 6,800 adults from different racial and ethnic backgrounds to understand how heart disease develops over time. Participants were healthy at the start and were monitored for risk factors and heart-related events like heart attacks and strokes. The goal is t…

This study uses a special PET/MRI scan with an investigational tracer called [18F]DPA-714 to see if a heart attack leads to inflammation in the brain. Researchers will compare 6 people who recently had a heart attack with a control group. The goal is to better understand the link…

This study looks at whether giving people a personalized genetic risk score for coronary artery disease helps doctors make better decisions about prevention. About 1,000 adults with moderate heart risk will be randomly assigned to receive their risk score or not. Researchers will…

This study looks at 15 people who had a heart attack but whose arteries were not blocked. Researchers use two types of imaging—one inside the artery and one MRI of the heart—to find hidden plaque or damage that might explain the attack. The goal is to better understand these puzz…
