Massive study pits diabetes drugs against each other for heart protection
NCT ID NCT07096063
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at real-world medical records from over 887,000 people with type 2 diabetes, overweight, and heart risk to compare two drugs: tirzepatide and semaglutide. The goal was to see which one better prevents serious heart problems like heart attack, stroke, or death. The study did not give anyone new treatment but instead analyzed existing data to learn how to use real-world information for future research.
