Increased risk in those with preexisting CKD, other risk factors for renal disease (HTN or CAD), and those on ACEIs/ARBs. The effects of GLP-1 agonists are associated with the dose. Higher doses of GLP-1 agonists are associated with weight loss. Take for example semaglutide. Ozempic is utilized for DM2 in doses of 0.5, mg SQ every week.

This MI wasn’t caused by a ruptured plaque of CAD - it was a coronary artery dissection of the RCA. A study by Hassan et al. Lobo et al. This case occurred 10+ years ago.
