Semaglutide may reduce cardiovascular events in non-diabetic patients.

Last updated July 6, 2026

Key finding

The primary end point of first major adverse cardiovascular event (MACE) was reduced by 20% with semaglutide versus placebo.

The study evaluated the effects of semaglutide on cardiovascular events in individuals with overweight or obesity and established cardiovascular disease without diabetes, finding a 20% reduction in major adverse cardiovascular events.

Plain-language summary

What this paper says

A plain-language read of the study’s main message and where it applies.

Study focus

The study evaluated the effects of semaglutide on cardiovascular events in individuals with overweight or obesity and established cardiovascular disease without diabetes, finding a 20% reduction in major adverse cardiovascular events.

Clinical relevance

The findings are clinically significant as they suggest that semaglutide can be an effective intervention for reducing cardiovascular risks in a high-risk population. Given the increasing prevalence of obesity and related cardiovascular diseases, this treatment could help improve patient outcomes and reduce healthcare costs associated with cardiovascular events.

Keep in mind

The study's population may not be generalizable to all individuals with cardiovascular disease. Long-term effects of semaglutide on cardiovascular outcomes remain unclear. The trial did not include participants with diabetes, limiting applicability.

Main Effects

Semaglutide reduced the first major adverse cardiovascular event (MACE) by 20% compared to placebo.

Cardiovascular mortality risk reduction was consistent across baseline HbA1c groups.

Other cardiovascular outcomes, including nonfatal myocardial infarction and stroke, showed consistent trends across HbA1c subgroups.
