  • Strongly recommended

    With type 2 diabetes, a GLP-1 receptor agonist is one of the two drug classes that lower cardiovascular risk beyond their effect on blood sugar — and guidelines now favour it for that reason.

    Proven in trialsTrials counted real events, like heart attacks, strokes, or deaths, and this changed them.

    Why, and the source

    Semaglutide, liraglutide and dulaglutide each reduced cardiovascular events in people with type 2 diabetes at raised risk, and oral semaglutide reproduced it in SOUL. Tirzepatide was tested differently and more informatively: SURPASS-CVOT compared it head-to-head against dulaglutide — an active drug, not placebo — in people with diabetes and cardiovascular disease, and met non-inferiority for major events while producing markedly more weight loss and better A1c, blood pressure and lipids. Which of these suits you depends on your kidney function, whether weight loss is a goal, and cost.

    Where the guidelines stand

    ACC/AHA (US)

    • RecommendsClass 1Level A

      ACC/AHA rates either an SGLT2 inhibitor or a GLP-1 receptor agonist with proven cardiovascular benefit Class 1, Level A in chronic coronary disease with type 2 diabetes. The 2024 PAD guideline gives liraglutide and semaglutide the same grade in PAD with type 2 diabetes. Tirzepatide is not named in either, so this grade covers the drug class, not tirzepatide itself.

    ESC (Europe)

    • RecommendsClass ILevel A

      The ESC grade of I, A is for SGLT2 inhibitors with proven benefit in type 2 diabetes with chronic coronary syndrome. The ESC's GLP-1 agonist recommendation for this group was not separately read.
