Intermediate coronary syndrome

Researchers are testing whether a drug-coated balloon alone can keep heart arteries open after clearing a chronic total blockage, without leaving a permanent metal stent. The study plans to enroll 38 adults with a long-standing coronary occlusion and angina or documented ischemia…

This trial investigates whether patients with acute coronary syndrome can safely stop taking aspirin soon after a heart stent procedure and continue with only a potent antiplatelet drug (ticagrelor or prasugrel). The standard approach is to take both aspirin and a P2Y12 inhibitor…

This study tests whether the drug propranolol can prevent heart injury after breast cancer surgery in women who also have high blood pressure or angina. One hundred participants will either receive propranolol before surgery or standard care. Researchers will measure heart stress…

This trial is testing whether an artificial intelligence-enhanced electrocardiogram (AI-ECG) can help doctors quickly and safely identify which people with non-cardiac chest pain are truly low risk. Half of the participants will receive the AI-ECG in addition to standard care, wh…

This trial compares two blood-test strategies for diagnosing heart attacks in people with chest pain: the standard approach of testing at arrival and again 3 hours later, versus an accelerated approach testing at arrival and again after just 1 hour. The goal is to see whether the…

This study tests a new, contactless camera technology that measures heart rate, blood pressure, and heart disease risk from a short video of your face. Researchers will compare these readings to standard medical tests in 300 adults aged 30 and older in Jakarta. If accurate, this …

This study tests a small mesh device called a coronary sinus reducer in 25 people with severe chest pain from advanced coronary artery disease who cannot have stents or bypass surgery. The device is placed in a heart vein to increase pressure and improve blood flow. Researchers w…

This study looks at whether adding a special heart function test (coronary function testing) to the standard artery-opening procedure (angioplasty) can better relieve chest pain and improve quality of life. About 450 adults with a significant blockage in a major heart artery will…

This study will follow 6000 people with heart disease or recent heart attacks for years. Researchers will collect blood, urine, and stool samples, plus medical data, to build a huge database. They hope artificial intelligence can find new ways to predict, diagnose, and treat hear…

This study develops and tests an AI system that reads de-identified patient admission notes to classify four types of coronary syndromes, including heart attacks and angina. The tool is designed to protect patient privacy while helping doctors diagnose more accurately and quickly…

This study tests whether using very low radiation doses combined with special software can produce clear images of the heart's arteries. About 50 adults scheduled for a standard heart angiogram will have extra images taken with the new low-radiation method. The goal is to see if …
