It may mimic acute coronary syndrome but coronary angiography reveals normal epicardial coronary arteries.1),2) In our case, the selleck chemicals patient was a postmenopausal woman, however no triggering event was identified. A stressful trigger is often, but not always present. In up to 22% of patients, there was no identified triggering event.3) The exact mechanism of takotsubo cardiomyopathy Inhibitors,research,lifescience,medical is not well known. Coronary vasospasm, disturbance of microcirculation, reperfusion injury and catecholamine overload are possible mechanisms.4) In the acute phase, the

treatment is generally supportive.2) The prognosis is favorable with the normalization of wall motion abnormalities within weeks.5) The complications of takotsubo cardiomyopathy are thought to be infrequent and different from those of the acute coronary syndrome, although there is inadequate literature evaluating

the true incidence of these complications such as heart failure, cardiogenic shock, ventricular arrhythmias, ventricular Inhibitors,research,lifescience,medical rupture, Inhibitors,research,lifescience,medical and death.1) In our case, the finding of ST elevation and apical ballooning persisted over 3 months. The prolonged abnormal findings are rare in a typical case of takotsubo cardiomyopathy.1),4-9) The mechanism of persistent ST elevation and apical ballooning is unclear. Some reports suggested that corticosteroid use might retard the improvement of left ventricular dysfunction.4),6) However Inhibitors,research,lifescience,medical this is controversial, and a recent meta-analysis on corticosteroid use in myocardial infarction suggested that these drugs had no harmful effects on clinical outcomes.10) In this case, the steroid treatment was maintained with varying doses for the control of SLE activity. Inhibitors,research,lifescience,medical Another interesting finding was the development of

the apical mural thrombus. There are a few reports of thrombus associated with takotsubo cardiomyopathy.1),5),7),8) It is thought that the thrombus may have been precipitated by the ventricular dyskinesis combined with an increased sympathetic activation which alters the coagulation cascade.5) The clinical importance of this thrombus is that it may be a potential source of embolic events.7) Echocardiography and cardiac magnetic resonance imaging may be useful techniques for the detection of an apical thrombus.1) Serial and echocardiographic studies and anticoagulation therapy were useful for this complication, as were performed in this case. This is a rare case of persistent apical ballooning complicated by an apical thrombus in takotsubo cardiomyopathy of SLE patient. Takotsubo cardiomyopathy may not be always transient and left ventricular thrombus can occur in the disease course as our patient. This is important for the treatment and management of patients with takotsubo cardiomyopathy.
