Research Summary
Analyzed using Evidence Intelligence™

Dapagliflozin reduces IL-1B but does not improve cardiac fibrosis in T2D patients.

Last updated July 6, 2026

Key finding

Plasma IL-1B was reduced (−1.8 pg/mL, P = 0.003)

This study investigated the effects of dapagliflozin on cardiovascular outcomes in diabetic patients, revealing significant changes in plasma IL-1B and ketones.

Plain-language summary

What this paper says

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

Study focus

This study investigated the effects of dapagliflozin on cardiovascular outcomes in diabetic patients, revealing significant changes in plasma IL-1B and ketones.

Clinical relevance

These findings suggest that dapagliflozin may provide cardiovascular benefits for diabetic patients by reducing inflammation and altering metabolic markers. Understanding these mechanisms could lead to better management strategies for diabetes-related cardiovascular risks.

Keep in mind

Limited to a specific population of diabetic patients. Short follow-up period of 12 months may not capture long-term effects. No significant changes in several cardiovascular metrics.

Main Effects

Plasma IL-1B was reduced by −1.8 pg/mL (P = 0.003).

Plasma ketones increased by 0.26 mM (P = 0.0001).

PBMC maximal oxygen consumption rate did not change in the dapagliflozin group.
