This study compares two treatments for coronary artery disease: a drug-coated balloon (DCB) and a drug-eluting stent (DES). Researchers will measure how much the artery narrows again after treatment using ultrasound. About 256 adults with blocked heart arteries will take part to …

This study looks at people who had a certain type of heart attack (NSTEMI) and have multiple blocked heart arteries. It compares fixing all blockages right away during the first procedure versus waiting a few days to fix the non-critical blockages. The goal is to see which approa…

This study looks at 780 adults with a type of heart attack (NSTEMI) who also have sudden heart failure (fluid in the lungs). Half will get a coronary angiogram (X-ray of heart arteries) within 2 hours of diagnosis, and the other half will wait until their breathing improves. The …

This study tracks 15,000 people who had a retinal artery occlusion, or 'eye stroke,' to see how often they later have heart attacks, strokes, or other serious heart and brain events. Researchers will use a national health database to look at long-term outcomes and see if common m…

This study looks at people who had a heart attack but whose main heart arteries are not blocked. Researchers want to see if problems in the tiny blood vessels of the heart affect future health. 150 adults will be followed to track heart-related events like another heart attack or…

This study compares two ways of guiding heart artery treatment in people having a major heart attack. One method uses standard X-ray images (angiography), the other uses a more detailed light-based scan (OCT). The goal is to see which approach leads to fewer heart-related problem…

This study follows 2000 adults with suspected coronary artery disease who have had special imaging or pressure tests inside their heart arteries. Researchers will track major heart events like death, heart attack, or repeat procedures over many years. The goal is to learn which f…
