Cause and effect
2 studies reviewed
In plain English

In patients with type 2 diabetes and heart disease, tirzepatide lowers the combined risk of serious heart and kidney events by 16% compared to dulaglutide.

See the scientific wording

Tirzepatide reduces the risk of a composite of major cardiovascular and renal outcomes by 16% compared to dulaglutide in patients with type 2 diabetes and established heart disease.

Why this might work

Tirzepatide helps the body use insulin better and reduces hunger, leading to lower blood sugar, less fat around organs, and better blood pressure and cholesterol. These changes make blood vessels healthier and reduce strain on the heart and kidneys, lowering the chance of heart attacks, strokes, and kidney damage.

What the research says

2 studies
  1. Study: Cardiovascular Outcomes with Tirzepatide versus Dulaglutide in Type 2 Diabetes.

    This study found that tirzepatide slightly lowered the risk of serious heart problems compared to dulaglutide in diabetic patients with heart disease, but not as much as the 16% claim says. It still suggests tirzepatide might be a bit better.

  2. Study: Cardiorenal Outcomes With Tirzepatide Compared With Dulaglutide in Patients With Diabetes and Cardiovascular Disease

    In people with type 2 diabetes and heart disease, tirzepatide was shown to lower the risk of serious heart and kidney problems by 16% compared to another common drug called dulaglutide.
