Whereas progress with respect to heart failure with preserved ejection fraction (HFpEF) is still slow, both ARNIs and SGLT2 inhibitors hold great promise for this condition as well, and large clinical trials are currently ongoing.
The aim of the ongoing MUSCAT-HF (It stands for Prospective Comparison of Luseogliflozin and Alpha-glucosidase on the Management of Diabetic Patients with Chronic Heart Failure and Preserved Ejection Fraction) trial is to evaluate the efficacy of luseogliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, versus voglibose, an alpha-glucosidase inhibitor, using brain natriuretic peptide (BNP) as the index of therapeutic effect in T2DM patients with HFpEF.
This review deals with the impact of SGLT2 inhibitors on LV diastolic function in patients with DM and their current potential for prevention of the future development of HFpEF in such patients.
