The present invention relates to methods and pharmaceutical compositions for the treatment of heart failure. Despite current available treatments, heart failure remains associated with high morbidity and mortality. In vitro, the inventors showed that PIKfyve is critical for the control of mitochondrial fragmentation, hypertrophic and apoptotic responses to stress. They also provide evidence that inactivation of PIKfyve by the selective inhibitor STA-5326 suppresses excessive mitochondrial ROS production and apoptosis through a SIRT3-dependent pathway in cardiomyoblasts. In vivo, the inventors showed that inhibition of PIKfyve improves cardiac function on two mouse models (high-fat-diet mice and pressure overload-induced heart failure mice). In particular, the present invention relates to PIKfyve inhibitors for treating heart failure in a subject in need thereof. Particularly, the inventors tested STA-5326, a PIKfyve inhibitor, on both in vitro and in vivo models.
