Tirzepatide treatment in adults with pre-existing type 2 diabetes significantly reduces the risk of major adverse cardiovascular events (MACE), including all-cause mortality and cerebral infarction, compared to semaglutide.

If you have type 2 diabetes, tirzepatide may offer greater cardiovascular protection than semaglutide, including a lower risk of heart attack, stroke, and death. This is based on real-world data showing a 46% lower risk of major adverse cardiovascular events with tirzepatide compared to semaglutide over a one-year follow-up period. Consult your doctor to see if this treatment is appropriate for you.

In individuals with pre-existing T2D (n = 8446), tirzepatide was associated with lower risk of the composite outcome (HR 0.54, 95% CI 0.38–0.76, p < 0.001), cerebral infarction (HR 0.45, 95% CI 0.24–0.84, p = 0.010) and all-cause mortality (HR 0.33, 95% CI 0.15–0.73, p = 0.004) compared to semaglutide.

Why this rating

Large retrospective cohort study (n=8,446) with propensity score matching, but observational design limits causal inference.
