Abstract

Little information is available concerning the mechanism(s) underlying Takotsubo cardiomyopathy (TTC), other than evidence of associated catecholamine secretion. Given the known effects of catecholamines on endothelial function, we tested the hypothesis that TTC might also be associated with impairment of nitric oxide (NO) signaling. We now report an evaluation of NO signaling in TTC patients (vs. aged-matched controls) in relation to (a) severity of the acute attack and (b) rate of recovery.
