BACKGROUND For reasons that remain unclear, whether type 5 adenylyl cyclase (AC5), 1 of 2 major AC isoforms in heart, is protective or deleterious in response to cardiac stress is controversial. To reconcile this controversy we examined the cardiomyopathy induced by chronic isoproterenol in AC5 transgenic (Tg) mice and the signaling mechanisms involved. METHODS AND RESULTS Chronic isoproteren...
Stress induced cardiomyopathy/Takotsubo cardiomyopathy (TSO CMO) has been widely reported. It is characterized by apical hypokinesis or akinesis. Variants of this called as inverted/reverse cardiomyopathies have been reported and are characterized by basal hypokinesis/akinesis and hypercontractility of apex. These are more common in younger population. We present an elderly female who had a var...
Takotsubo cardiomyopathy (TCM) is a variant of stress-induced cardiomyopathy, characterized by transient left ventricular dysfunction that may be associated with emotional or physical triggers. We present the case of a 51-year-old Caucasian female with severe chronic obstructive pulmonary disease (COPD) who presented with syncope and was found to have her second lifetime episode of stress-induc...
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, co...
I read with interest the article by Sacco et al entitlted “TakoTsubo like Syndrome Triggered by Meperidine” on anaphylaxis probably causing takotsubo syndrome . Takotsubo cardiomyopathy is also called stress induced cardiomyopathy or the broken heart syndrome. It is most commonly triggered by emotional stress causing transient apical and/or apical left ventricular systolic dysfunction in the ab...
favorable prognosis with respect to malignant arrhythmia, a finding supported by other studies (4,5). As wall stress also is increased in advanced cardiomyopathy, the association between LGE and wall stress referred to by the authors is not surprising, because LGE also is a feature of advanced cardiomyopathy (4,5). One would expect that if increased wall stress is the underlying mechanism of my...
