Biochem/physiol Actions

Positive inotropic agent that inhibits Na + /K + -ATPase and increases activity of Ca 2+ -ATPase at the sarcoplasmic reticulum.



Istaroxime is a positive inotropic agent that inhibits Na + /K + -ATPase and increases activity of Ca 2+ -ATPase at the sarcoplasmic reticulum. It improves cardiac performance in the failing heart. Istaroxime ameliorates calcium dysregulation Zebrafish PLN R14del arrhythmogenic cardiomyopathy model.

The heterozygous Phospholamban p.Arg14del mutation is found in patients with dilated or arrhythmogenic cardiomyopathy. This mutation triggers cardiac contractile dysfunction and arrhythmogenesis by affecting intracellular Ca2+ dynamics. Little is known about the physiological processes preceding induced cardiomyopathy, which is characterized
