Diabetes Drug Mounjaro Linked to Lower Heart Risk, Study Finds

A large study has found that adding the weight-loss and diabetes drug tirzepatide to standard care reduces the chance of a serious heart event in people with type 2 diabetes and existing heart disease.

The British Medical Journal reported this week that tirzepatide — sold under the brand name Mounjaro — is associated with a lower risk of major cardiovascular events when added to standard treatment for patients managing both type 2 diabetes and heart disease. The findings come from a study published by the BMJ and covered in an accompanying commentary.

Tirzepatide belongs to a class of medicines called dual GIP/GLP-1 receptor agonists — sometimes referred to as ‘twincretins’ — which work by mimicking two gut hormones to lower blood sugar and reduce appetite, distinguishing it from older GLP-1-only drugs such as semaglutide. The drug is already licensed in the UK for type 2 diabetes — though this study focuses specifically on its potential benefit for people who also have established heart disease.

The association matters in Kent, where NHS Kent and Medway Integrated Care Board oversees care for a large population managing long-term conditions including diabetes and cardiovascular disease. Any evidence linking existing medicines to reduced heart risk is likely to inform future prescribing decisions at a local level, though changes to clinical guidelines take time and go through national review processes.

It’s worth being clear about what the study does and doesn’t say. An association between the drug and lower cardiovascular risk is not the same as proof that tirzepatide directly causes that reduction — researchers and clinicians will want to see findings replicated before drawing firm conclusions.

If you have type 2 diabetes and are concerned about your heart health or current medication, speak to your GP rather than adjusting any treatment yourself. NHS 111 can also offer advice if you’re unsure whether your symptoms need attention.
