Abstract

Heart failure (HF) and atrial fibrillation (AF) share common risk factors, frequently coexist and are associated with high mortality. Treatment of HF with AF represents a major unmet need. Here we show that a small molecule, BGP-15, improves cardiac function and reduces arrhythmic episodes in two independent mouse models, which progressively develop HF and AF. In these models, BGP-15 treatment is associated with increased phosphorylation of the insulin-like growth factor 1 receptor (IGF1R), which is depressed in atrial tissue samples from patients with AF. Cardiac-specific IGF1R transgenic overexpression in mice with HF and AF recapitulates the protection observed with BGP-15. We further dem..
