Abstract Purpose of review There are numerous health benefits to exercise, including improved cardiovascular, metabolic, and mental health. Despite these many benefits, children with cardiomyopathy have been traditionally restricted from engaging in exercise or participating organized sports. The purpose this is summarize the current literature regarding utility cardiopulmonary testing, discuss...

background: dilated cardiomyopathy is associated with a progressive deterioration in cardiac function and eventually death. initial interest in this hypothesis was to create another large animal model for dilated cardiomyopathy in addition to pigs and dogs . methods: after the induction of anesthesia to 10 female sheep, a carotid-jugular shunt was created in all the animals via a 1-cm fistula b...

The classic finding of Takotsubo's cardiomyopathy is left ventricular systolic dysfunction with echocardiographic evidence of apical ballooning in the absence of significant coronary disease. Intracranial hemorrhage is a known cause for stress-induced cardiomyopathy with a similar echocardiographic presentation. This diagnostic finding suggests a similar pathophysiologic mechanism between neuro...

Stress-induced cardiomyopathy, which is also known as takotsubo cardiomyopathy, is a cardiac syndrome of a transient, reversible left ventricular dysfunction that is caused by emotional and/or physical stress and surgery. Its clinical manifestations are similar to those of myocardial ischemia without a coronary artery lesion. Stress-induced cardiomyopathy is more common in middle-aged women, an...

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...

Stress-induced cardiomyopathy is caused by emotional or physical stressors and mimics acute myocardial infarction, though Stress-induced cardiomyopathy is characterized by reversible left ventricular (LV) apical ballooning in the absence of significant coronary artery disease. We describe a 51-year-old male who underwent left upper lobectomy for non-small cell lung cancer, and during which card...

Excess concentrations of catecholamines in pheochromocytoma can cause various clinical manifestations. There are few reports of pheochromocytoma presented with stress-induced cardiomyopathy (catecholamine-induced cardiomyopathy) after mild stress and the case of pheochromocytoma associated with nonocclusive stroke is more uncommon. We report a case of pheochromocytoma manifested repeated stress...

Acute catecholamine cardiomyopathy is an uncommon, life-threatening manifestation of pheochromocytoma. The massive release of catecholamines from the adrenal medulla and their toxic effects on the coronary vessels and the cardiac myocytes play a significant role in the pathogenesis of cardiomyopathy in patients with pheochromocytoma. Severe manifestations, such as acute catecholamine cardiomyop...

Takotsubo cardiomyopathy corresponds to a syndrome characterized by a transient myocardial dysfunction affecting the left ventricular apex that classically occurs after major physical or emotional stress (also called “broken heart syndrome” or “stress-induced cardiomyopathy”). The author describes the case of a patient with takotsubo cardiomyopathy induced by subarachnoid hemorrhage.

Hydroxychloroquine-induced cardiomyopathy is a rare adverse reaction with serious and potentially fatal outcomes. We report 56-year-old female who presented in acute right heart failure NYHA class III symptoms, ascites, raised JVP pressure, peripheral oedema. Significant medical history included SLE (diagnosed her late 20s, well controlled on hydroxychloroquine), CKD, poorly hypertension. Exten...
