This study aims to find the best time to perform a coronary angiography (a procedure to image the heart's arteries) in patients who have a specific type of heart attack that also causes sudden, severe heart failure. Researchers will compare doing the procedure immediately (within…

This study aims to find out if using a detailed imaging technique called OCT is better than standard angiography for guiding stent placement in people who have just had a major heart attack. Researchers will enroll 1,500 participants to see which method leads to fewer future hear…

This study is comparing two procedures for treating blocked heart arteries. It is testing a drug-coated balloon that inflates to open the artery and then is removed, against the standard drug-coated metal stent that stays in place permanently. The goal is to see if the balloon me…

This study aims to understand the long-term risks of heart attacks and strokes in people who have had a sudden 'eye stroke' (retinal artery occlusion). Researchers will track 15,000 patients in Korea using national health records to see how often these serious events happen. They…

This study aims to learn which advanced imaging techniques lead to the best long-term results for patients with clogged heart arteries. Researchers will follow 2,000 adults who have had a standard heart artery scan and an additional, more detailed scan. The goal is to see if usin…
