The Claim

In adults with type 2 diabetes initiating injectable therapy, initiation of a GLP-1 receptor agonist compared to basal insulin is associated with a 41% lower risk of all-cause death and a 41% lower risk of stroke over a median follow-up of 24 months, after adjustment for age, sex, diabetes duration, comorbidities, and concomitant medications.

In plain English

Among adults with type 2 diabetes who start injectable treatment, those who begin a GLP-1 receptor agonist have a 41% lower risk of dying from any cause and a 41% lower risk of having a stroke over two years compared to those who start basal insulin, based on observed data adjusted for other health factors.

See the scientific wording

In adults with type 2 diabetes initiating injectable therapy, starting a GLP-1 receptor agonist is associated with a 41% lower risk of all-cause death and a 41% lower risk of stroke compared to starting basal insulin over a median follow-up of 24 months, even after adjusting for age, sex, diabetes duration, comorbidities, and concomitant medications, suggesting a clinically meaningful cardiovascular benefit in real-world settings.

Why this might work

When a GLP-1 receptor agonist is used, it activates receptors in blood vessels and organs, which reduces swelling in the body and helps blood vessels work better. This makes it less likely for clots to form or for blood vessels to get blocked, which lowers the chance of stroke and death.

  1. Study: Cardiovascular outcomes after initiating GLP-1 receptor agonist or basal insulin for the routine treatment of type 2 diabetes: a region-wide retrospective study

    This study found that adults with type 2 diabetes who started a GLP-1 agonist shot had fewer heart attacks, strokes, and deaths over two years compared to those who started insulin, even after accounting for their age and other health problems. So yes, GLP-1 agonists seem safer for the heart than insulin in this group.
