The Claim
Among adults with type 2 diabetes and established atherosclerotic cardiovascular disease, weekly subcutaneous tirzepatide (up to 15 mg) is noninferior to dulaglutide (1.5 mg) in reducing the composite risk of death from cardiovascular causes, myocardial infarction, or stroke over a median follow-up of 4.0 years, with a hazard ratio of 0.92 (95.3% CI, 0.83 to 1.01), indicating no increased risk despite greater weight and glycemic improvements.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with type 2 diabetes and heart disease, a weekly injection of tirzepatide reduces the risk of heart-related death, heart attack, or stroke just as effectively as another drug called dulaglutide, even though tirzepatide leads to greater weight loss and better blood sugar control.

Tirzepatide helps the body use insulin better and reduces hunger, leading to lower blood sugar and weight loss. This lowers fat buildup in blood vessels, reduces inflammation, and eases pressure on the heart, which together prevent heart attacks, strokes, and heart-related deaths.
What the research says
1 studyStudy: Cardiovascular Outcomes with Tirzepatide versus Dulaglutide in Type 2 Diabetes.
In people with type 2 diabetes and heart disease, tirzepatide didn't cause more heart attacks, strokes, or heart-related deaths than dulaglutide, even though it helped them lose more weight and control blood sugar better.
