conclusions the mechanism of mid-variant of dobutamine-induced stress cardiomyopathy remains unclear. we think that multiple mechanisms are involved and this risk should be considered in patients with comorbid psychiatric conditions and with use of centrally acting stimulants. case presentation we report a 48-year-old female with intermittent chest pain. her physical exam, cardiac enzymes and t...

apical ballooning syndrome (abs) is a reversible cardiomyopathy with presentation mimicking an acute coronary syndrome. so in clinical practice, it is essential to consider it in the differential diagnosis of patients presenting with chest pain, especially in postmenopausal women. coronary angiography is usually indicated to achieve a proper diagnosis. typically, patients do not have significan...

stress-induced cardiomyopathy or takotsubo cardiomyopathy is a recently increasing diagnosed disease manifested by transient apical or mid left ventricular dilation and dysfunction. this sign is similar to acute myocardial infarction but without significant coronary artery stenosis. there are important and essential differences between takotsubo cardiomyopathy and acute myocardial infarction in...

takotsubo or stress-induced cardiomyopathy is a cardiomyopathy in which the patient has a sudden onset, reversible left ventricular systolic dysfunction without any significant coronary artery disease. four women, who were at a mean age of 64 years and suffered from chest pain exacerbated by emotional stress, were admitted as cases of acute coronary syndrome and were completely evaluated throug...

toxic effects of monensin, a polyether antibiotic mainly used as a coccidiostat, have been described in a wide range of animals. the present study was performed to investigate the toxic effects of monensin in goats. seven adult goats were administered sodium monensin, 13.5 mg kg-1, daily for five consecutive days via gastric gavage. monensin toxicity was evaluated by clinical signs, serum bioch...

Introduction: Differentiating between ischemic cardiomyopathy (ICM) and idiopathic dilated cardiomyopathy (IDCM) is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction (EF) introducing a noninvasive tool to diagnose those who will benefit from angiography seems...

In this article we describe a rare clinical condition of stress cardiomyopathy (takotsubo cardiomyopathy) for which we, despite controversy and lack data, identified the main pathogenic pathways (including direct toxic effect catecholamines on myocardium, catecholamine-mediated myocardial stunning, microcirculation disorders). After systematic review, distinct pathology features new diagnostic ...

Takotsubo cardiomyopathy, also called stress-induced cardiomyopathy, usually occurs in patients with severe emotional or physiologic stress. The prognosis is favorable, and the wall motion abnormlities normalize within weeks. However, stress-induced cardiomyopathy is rarely assosicated with left ventricular thrombus and thromboembolic complications. Here, we report a case of stress-induced card...

BACKGROUND Due to the rise in the number of reports of stress cardiomyopathy in the literature, awareness of this condition is increasing. Although different names have been used to describe this condition, the similarities in clinical, electrocardiographic, echocardiographic, and angiographic features suggest that they represent the same spectrum of diseases with different underlying causes. T...
