Association of SGLT2 inhibitors and new-onset dementia in non-diabetic patients with heart failure
Main finding · New-onset dementiaResult — go to the resultHazard ratio 0.77 95% CI 0.68–0.87Authors' conclusion
In this large, real-world patient with HF without diabetes, SGLT2i therapy was associated with a significantly lower risk of new-onset dementia and all-cause mortality.
