This study compares two ways to treat narrowed heart arteries: a drug-coated balloon (DCB) and a drug-eluting stent (DES). Researchers will measure how much the artery narrows again over time using ultrasound. About 256 adults with significant blockages will take part to see whic…

This study compares two ways to guide stent placement during a heart attack: standard angiography (X-ray) versus a more detailed imaging method called optical coherence tomography (OCT). The goal is to see if OCT leads to fewer future heart problems, like repeat blockages or hear…

This study looks at the best timing for opening blocked arteries in people having a certain type of heart attack (NSTEMI) who have multiple blockages. About 1,014 participants will be randomly assigned to have all blockages fixed during the same procedure or to wait a few days be…

This trial tests whether doing a coronary angiogram (a special X-ray of the heart arteries) within 2 hours of diagnosis is better than waiting until the patient's heart failure symptoms improve. The study includes 780 adults with a type of heart attack called NSTEMI who also have…

This study looks at 150 adults who had a heart attack but whose main heart arteries were not blocked. Researchers will use special imaging and pressure tests to check for problems in the tiny blood vessels of the heart. The goal is to see if these microvascular issues lead to wor…

This study follows 15,000 people who had a retinal artery occlusion, or 'eye stroke,' to track their long-term risk of heart attack, stroke, and death. Researchers will analyze medical records from a Korean national database to see how different treatments, like blood thinners an…

This study follows 2000 adults with suspected heart artery disease who undergo special imaging and pressure measurements during a heart catheterization. Researchers want to see which test results best predict future heart problems like heart attacks or the need for another proced…
