This effect has led to its use for treating erectile dysfunction. Although its influence on rest heart function has appeared minimal, recent animal studies suggest that sildenafil can have potent effects on hearts stimulated by beta-adrenergic or pressure overloads. We therefore tested whether sildenafil blunts dobutamine-stimulated cardiac function in humans.
