MYOCARDIAL REPERFUSION INJURY

This study tested whether breathing air with low and then high oxygen before heart bypass surgery could help protect the heart from damage. 120 adults scheduled for bypass surgery took part. The approach is drug-free and aims to reduce complications after surgery.

This study tested whether giving a single, strong dose of steroids to people right after a major heart attack (STEMI) could reduce the amount of heart muscle that gets permanently damaged. The steroid was given before the standard emergency procedure to open the blocked artery. T…

This study looked at whether a specific heart procedure, done a few minutes after blood flow returns naturally, can limit heart muscle damage in people having a major heart attack. 72 adults with a first heart attack and partially open arteries took part. Researchers measured hea…

This study looked at 250 people who had a severe type of heart attack involving bleeding into the heart muscle. Researchers tested whether a measurement called the wall strain index ratio, taken from a heart MRI, could identify areas of the heart at risk of tearing (rupture). The…

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 study tested new MRI methods to detect bleeding inside the heart muscle after a heart attack. Researchers studied 14 patients to see if these scans could better identify damage that raises the risk of heart failure. The goal was to improve imaging, not to test a treatment.
