Jabs like Wegovy and Ozempic may cut the risk of life-threatening complications after a heart attack, researchers have discovered. GLP-1 drugs were found to have a powerful effect in preventing tissue damage, which has the potential to cut the risk of serious problems that affect up to half of all patients suffering a heart attack. Experts believe they could be given by paramedics at the scene if somebody has suffered a heart attack. "But our latest findings are surprising in that we have found GLP-1 drugs may prevent this problem." Using mice, the team found GLP-1 drugs improved blood flow to the heart following a heart attack by activating potassium channels and thus relaxing pericytes.
