Tirzepatide (TZP) reduces the risk of four-component major adverse cardiovascular events (MACE-4) in patients with type 2 diabetes (T2DM) and obesity compared to placebo, with the 15mg dose showing the most significant reduction.

If you have T2DM or obesity, Tirzepatide (TZP) can significantly lower your risk of major cardiovascular events (like heart attack or stroke) compared to a placebo. The 15mg dose is the most effective for heart protection, but it also comes with a higher risk of side effects like nausea. Patients with T2DM seem to get more heart benefits and fewer side effects than those with obesity alone. Talk to your doctor about whether the cardiovascular benefits outweigh the potential side effects for you.

GoodSupportsHIGH confidence
Compared to placebo, TZP 5mg, TZP 10mg and TZP 15mg all reduced the incidence of MACE-4 (RR [95% CI], 0.47 [0.23 to 1.12], 0.46 [0.15 to 1.48], 0.38 [0.17 to 0.84], respectively)... TZP 15mg reduced the risk of cardiovascular events more significantly than TZP 5mg, TZP 10mg, GLP-1RAs, and insulin.
