Abstract:
Myocardial stunning with hyperthyroidism is rare. A 79-year old woman with hyperthyroidism was admitted to our hospital complaining of palpitations due to paroxysmal atrial fibrillation. An echocardiogram showed akinesis of the apical wall which was not observed 2 weeks before admission. Cardiac catheterization performed in the acute phase showed normal coronary arteries and no evidence of provocative spasms. The wall motion abnormality disappeared entirely after 1 week in hospital. We report a case of transient left ventricular dysfunction, so called "takotsubo" cardiomyopathy, associated with hyperthyroidism.
