What the source says

This review discusses tirzepatide and SGLT2 inhibitors in heart failure with preserved ejection fraction and obesity. Evidence from separate treatments or trials does not establish that a combined regimen was tested or is suitable for an individual patient.

Evidence and limits

The authors synthesise separate trial and mechanistic evidence. They state that differences between trial populations prevent a valid direct comparison and that the combination has not been tested in a dedicated randomised trial. Complementary mechanisms do not establish the safety or benefit of combining medicines.

What we checked

We checked the primary publication record and available abstract. The full paper and supplements have not been reviewed for this correction.

SHIFT’s take

What we think this could mean for you, and what remains uncertain.
