Semaglutide significantly reduces Major Adverse Cardiovascular Events (MACE) and hospitalization for heart failure (HHF) risk, while Tirzepatide significantly reduces HHF risk, offering cardiovascular protection beyond weight loss.

If you have obesity and cardiovascular disease or heart failure, Semaglutide and Tirzepatide are not just weight loss drugs; they offer proven cardiovascular protection. Semaglutide reduces the risk of major heart events, and Tirzepatide reduces hospitalizations for heart failure. These benefits are independent of, but additive to, the weight loss achieved.

GoodSupportsHIGH confidence
Semaglutide was effective in reducing major adverse cardiovascular events... Tirzepatide was effective in... reduction in hospitalization due to heart failure.
