Key clinical point: Empagliflozin showed a beneficial effect on cognitive and physical impairment in frail older patients with type 2 diabetes (T2D) and heart failure with preserved ejection fraction (HFpEF).
Major finding: The mean Montreal Cognitive Assessment score significantly improved from baseline to 1 month in the empagliflozin group (19.80 vs. 22.25; P < .001) but not in the metformin (P = .26) and insulin ( P = .81) groups, with empagliflozin showing a significant effect on amelioration of cognitive impairment (odds ratio 3.609; P = .03). The 5-meter gait speed improved significantly in the empagliflozin and metformin groups (both P < .05), but not in the insulin group.
Study details: This prospective observational study included 162 frail older patients aged >65 years who had T2D and HFpEF and were treated with empagliflozin (n = 52), metformin (n = 56), or insulin (n = 54).
Disclosures: The study was partly supported by the US National Institute of Diabetes and Digestive and Kidney Diseases, US National Heart, Lung, and Blood Institute, and US National Institute on Aging, among others. The authors declared no conflicts of interest.
