Authors' conclusion

In obese individuals without diabetes, tirzepatide was associated with a lower risk of cardiovascular events, especially incident HF, compared with semaglutide, with a similar safety profile.

Study context

Population
Adults ≥18 years without diabetes initiating tirzepatide or semaglutide for obesity, November 2023–August 2024; excluded recent atherosclerotic events, prior heart failure (HF) or crossover to comparator35,336 matched pairs
Exposure
Tirzepatide vs semaglutide
Outcome
Major cardiovascular events: all-cause death, acute coronary syndrome, stroke or new-onset HF
Follow-up
12 months
