Acute subendocardial myocardial infarction

This early-stage trial tests whether an experimental drug called UDP-003 is safe in healthy volunteers and people with heart disease. Researchers will give single or multiple doses of the drug or a placebo and monitor for side effects. The study includes 84 participants and is th…

This study looks at whether using aspirin alone is as effective and safer than aspirin plus another blood thinner (fondaparinux) before a heart procedure in people with a type of heart attack called NSTEMI. About 5,000 participants will be randomly assigned to one of the two trea…

This study tests whether taking only the blood thinner ticagrelor (instead of the usual combination of ticagrelor plus aspirin) can reduce bleeding after a heart attack. It involves 2,570 adults who had a heart attack but did not receive stents or bypass surgery. Participants wil…

This study tests a special balloon coated with two drugs to open blocked heart arteries in people with chest pain or minor heart attacks. The balloon is used instead of placing a new stent. About 30 participants will be followed for 12 months to see if the artery stays open and i…

This study explores whether performing a cardiac MRI (CMR) before the standard invasive coronary angiography (ICA) can accurately diagnose the cause of a suspected non-ST-elevation heart attack (NSTEMI). Currently, patients with NSTEMI often undergo an invasive angiogram, and if …

This study is testing whether artificial intelligence (AI) can predict or rule out a heart attack using data from standard blood tests. Researchers will analyze white blood cell properties from over 3,000 adults who come to the hospital with chest pain. The goal is to see if AI c…

This study tests a new, quick blood test done right in the emergency room to rule out heart attacks in people with chest pain. The goal is to see if this faster test can get patients discharged sooner compared to the usual lab test, which can take an hour or more. About 1,500 adu…

This study tests a new CT scan that works without an ECG to quickly check for heart disease in people with chest pain and high troponin levels. About 230 adults will get this scan plus the standard invasive test to see if the new method is accurate. If successful, it could reduce…

This study is a large registry that will collect information from 10,000 adults who undergo exercise echocardiography (a heart ultrasound during exercise) as part of their regular care. The goal is to better understand how the heart works during exercise in people with various he…

This study examines how frailty and other health factors affect the short- and long-term outlook for people aged 75 and older who are hospitalized for a heart attack or unstable angina. Researchers will compare two treatment approaches—a procedure to open blocked arteries versus …

This study follows 20,000 heart attack patients who are discharged early from the hospital after a minimally invasive procedure. Researchers want to see how well medications are adjusted, track major heart events, and measure quality of life over one year. No new treatment is giv…

This study looks at whether people having urgent heart catheterization need to fast beforehand. 400 patients with chest pain or mild heart attacks will be randomly assigned to either fast as usual or eat and drink normally. Researchers will measure comfort and safety to see if sk…

This study reviews medical records of 200 adults who came to the ER with a heart attack or unstable chest pain. It compares what happens when patients get two blood thinners (aspirin plus another) in the ER versus waiting to give the second one in the catheterization lab. The goa…

This study looks at 1,600 people who recently had a heart attack to see if a common blood test (the neutrophil-to-lymphocyte ratio, or NLR) can help predict who is at higher risk of dying or having another heart problem within 6 months. Researchers will measure NLR from blood sam…
