Severe transient left ventricular dysfunction induced by thyrotoxicosis

Abstract

We report on a 44-year-old woman presenting with chest pain and dyspnoea without previous stress-related events. By means of echocardiography severe left ventricular dysfunction and wall motion abnormalities resembling stress-induced cardiomyopathy (Tako Tsubo) were seen. Laboratory investigation revealed thyrotoxicosis and elevated cardiac markers. Six days after starting medical treatment, complete restoration of the left ventricular function was observed. The transient left ventricular dysfunction was induced by thyro-toxicosis resembling stress-induced cardiomyopathy that resolved completely after medical treatment. © The Author(s) 2011.
