This study looks at how cardiac arrest affects thinking, memory, emotions, and sleep over time. About 200 survivors will take detailed brain tests 7 and 24 months after their cardiac arrest. Their results will be compared to heart attack patients who did not have a cardiac arrest…

This study looked at whether a technique called postconditioning, done during angioplasty to reopen blocked heart arteries, can reduce damage to the heart muscle. 44 adults having their first heart attack took part. The researchers used MRI scans to measure the area of blocked sm…

This completed study of 88 heart attack patients looked at why some develop kidney injury after receiving contrast dye during a procedure to open blocked arteries. Researchers analyzed medical records to find which factors—like age, lab results, or procedure details—were linked t…

This completed study looked at whether patients hospitalized for a heart attack, stroke, or other cardiovascular event received the right medications to prevent future problems. Researchers reviewed records of 129 patients to see if doctors prescribed cholesterol-lowering drugs a…

This study looked at 10,000 people who came to the emergency room with chest pain. Researchers tested new blood markers to see if they could diagnose heart attacks faster than current methods. The goal is to help doctors quickly rule out or confirm a heart attack, especially in t…

This study looked at 1,586 heart attack patients who had multiple blocked arteries. After opening the main blockage, doctors compared doing a second procedure to fix the other blockages either early (within a few days) or later (weeks after). The goal was to see which timing bett…

This study tested whether briefly restricting blood flow to an arm (remote ischemic conditioning) before opening a blocked heart artery could reduce heart damage. Only 2 patients took part, so the results are not meaningful. The study looked at heart function, kidney problems, an…
