GLP-1 agonists are also associated with improved ejection fraction, coronary blood flow, and cardiac output while reducing the risk of cardiovascular events, infarction size, and all-cause mortality. Adverse events are common in those using GLP-1 agonists, but the vast majority of these are minor. Take for example semaglutide.

No one can tell you who will be that very next person to dial 9-1-1; however, it is imperative for the effectiveness of deployment that we concede that people and events often follow certain predictable patterns. Your existing historical CAD records contain the necessary information to build such dynamic views in real-time.

However, a smooth tapering of the mid-RCA was seen, highlighted in red below: How do we explain the MI if no sign of CAD was found? This MI wasn’t caused by a ruptured plaque of CAD - it was a coronary artery dissection of the RCA. This case occurred 10+ years ago.
