Key finding
Hazard ratio for risk of the composite HF outcome with oral semaglutide vs placebo was 0.78 (95% CI, 0.63-0.96).
This study evaluated the effect of oral semaglutide on heart failure events in patients with type 2 diabetes, finding a reduced risk of composite heart failure outcomes compared to placebo.

Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
This study evaluated the effect of oral semaglutide on heart failure events in patients with type 2 diabetes, finding a reduced risk of composite heart failure outcomes compared to placebo.
These findings are significant as they suggest that oral semaglutide could be an effective treatment option for reducing heart failure risk in patients with type 2 diabetes, a population already at increased risk for cardiovascular complications. This could lead to improved management strategies for diabetes and heart health.
Study design limited to a specific population of type 2 diabetes patients. Effectiveness of oral semaglutide in broader populations remains unclear. Potential unmeasured confounders may affect the results.

Oral semaglutide reduced the risk of composite heart failure outcomes with a hazard ratio of 0.78 (p=0.03).
The risk of major adverse cardiovascular events was lower with oral semaglutide (hazard ratio 0.83, p=0.05).
No significant differences were found in hypoglycemia or hyperglycemia events between the treatment and placebo groups.
