Prognostic importance of the oxidized product of catecholamines, adrenolutin, in patients with severe heart failure

OBJECTIVES: The purpose of this study was to assess whether adrenolutin, the inert product of the highly reactive molecules aminochromes, is increased in severe chronic heart failure and whether it is associated with a poor prognosis. BACKGROUND: Experimental evidence suggests that oxidative products of catecholamines, aminochromes, are more cardiotoxic than unoxidized catecholamines and may be increased in heart failure.
