The Claim

Tirzepatide reduces all-cause mortality by 16% compared to dulaglutide in adults with type 2 diabetes and established cardiovascular disease over a median follow-up of 47 months, with a hazard ratio of 0.84 (95% CI, 0.75–0.94).

In plain English

In adults with type 2 diabetes and heart disease, tirzepatide is associated with a 16% lower risk of death from any cause over about four years compared to dulaglutide.

See the scientific wording

Tirzepatide reduces all-cause mortality by 16% compared to dulaglutide in adults with type 2 diabetes and established cardiovascular disease over a median follow-up of 47 months, with a hazard ratio of 0.84 (95% CI, 0.75–0.94).

Why this might work

Tirzepatide helps the body use insulin better and lose weight, which lowers blood sugar and reduces strain on the heart and blood vessels, making it less likely for someone with diabetes and heart disease to die from heart or circulation problems.
