Targeting Mitochondrial Dysfunction With Elamipretide (SS-31) Improves Skeletal Muscle Performance in a HFpEF Rat Model.

Vahle B, Weidner S, Tomalka A, et al. Circulation. Heart failure. 2026.
Weak / noneAnimal (in vivo)Mentions: SS-31

Editor's note

A controlled rat study showing SS-31 improving skeletal-muscle function in a HFpEF model, with a plausible cardiolipin-stabilization mechanism. Evidence remains preclinical and animal-only.

Plain-language abstract

In a rat model of heart failure with preserved ejection fraction, elamipretide (SS-31) improved skeletal-muscle force and reduced muscle atrophy, apparently by stabilizing cardiolipin.
