This study compares two ways to treat blocked heart arteries: a drug-coated balloon (DCB) and a drug-eluting stent (DES). About 256 adults with coronary artery disease will be enrolled. The goal is to see which method keeps arteries open longer by measuring changes inside the ves…

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 versus fixing the main one first and the others a few days later. The goal is to see which approach reduces the risk of…

This study aims to find out if using a detailed imaging technique called OCT leads to better long-term results than standard angiography when placing stents in people who have just had a major heart attack. It will involve 1500 participants who are having emergency stent placemen…

This study looks at 780 adults who had a certain type of heart attack (NSTEMI) and also developed sudden heart failure. It compares getting a heart artery scan within 2 hours of diagnosis versus waiting until the patient is stable. The goal is to see which approach better prevent…

This study tracks 15,000 people who had a retinal artery occlusion (eye stroke) to see how often they later have heart attacks, strokes, or die from heart-related causes. Researchers will analyze national health records to understand these risks and find out which medications (li…

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 (called microvascular dysfunction) affect future health. 150 adults will be followed to compare outcomes lik…

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…
