Abstract

Two similar rare cases of recurrent ampulla (takotsubo) cardiomyopathy, which was induced by physical stress of recurrent rhabdomyolysis in case 1 and aggravation of respiratory disease in case 2, are presented. At the initial admission, both patients had typical ampulla cardiomyopathy, which was indicated by transient left ventricular (LV) apical ballooning, but at the second admission, they both had atypical ampulla cardiomyopathy, as diagnosed by transient basal midventricular ballooning. Electrocardiograms at each admission showed a specific T-wave inversion, which might indicate the region of LV asynergy, and prolongation of the QT interval. In both cases, the plasma level of endogenous catecholamines was high. It is possible that excessive sympathetic stimulation induced by physical stress was the cause of this cardiomyopathy, but the cause of the differences in wall motion abnormalities between the first and second admissions was not identified. Appropriate management and treatment of the underlying disease and determining the mechanisms of recurrent ampulla cardiomyopathy might prevent its recurrence.
