Case Report
"Tako-Tsubo" Cardiomyopathy and Duloxetine Use
Abstract
We report the case of a 68-year-old woman in whom the use of duloxetine, a potent serotonin and norepinephrine reuptake inhibitor, was associated with "tako-tsubo" cardiomyopathy (TTC). Although several pathophysiological mechanisms for TTC have been proposed, available evidence suggests that an excess of catecholamines may play a major role. Our patient had a history of myocardial infarction with normal coronary arteries, probably the first manifestation of TTC. We speculate that duloxetine may have precipitated TTC by increasing plasma catecholamine concentration in a predisposed patient.This content is limited to qualifying members.
