Used primarily in research settings to study cardiac function, particularly as a partial beta-1 adrenergic agonist. It has been investigated for its potential to improve heart contractility in chronic heart failure due to its selective stimulation of beta-1 receptors in the myocardium. However, clinical use has been limited due to mixed outcomes in long-term studies, including increased mortality risk in some patient groups. Mainly employed in pharmacological research to understand adrenergic receptor dynamics and heart failure mechanisms.
