Transient myocardial ischemia during acetylcholine-induced coronary microvascular dysfunction documented by myocardial contrast echocardiography.
A 77-year-old white woman was referred for diagnostic coronary angiography after a 6-month history of exertional breathlessness and back pain. Her cardiovascular risk factors were hypercholesterolemia (low-density lipoprotein, 153 mg/dL) and a positive family history for cardiovascular disease (father died at 73 years of age because of a peripheral artery occlusive disease event). Furthermore, ...
متن کاملPheochromocytoma Is Characterized by Catecholamine-Mediated Myocarditis, Focal and Diffuse Myocardial Fibrosis, and Myocardial Dysfunction.
BACKGROUND Pheochromocytoma is associated with catecholamine-induced cardiac toxicity, but the extent and nature of cardiac involvement in clinical cohorts is not well-characterized. OBJECTIVES This study characterized the cardiac phenotype in patients with pheochromocytoma using cardiac magnetic resonance (CMR). METHODS A total of 125 subjects were studied, including patients with newly di...
متن کاملProtective Effects of D-Penicillamine on Catecholamine-Induced Myocardial Injury
Iron and copper release participates in the myocardial injury under ischemic conditions and hence protection might be achieved by iron chelators. Data on copper chelation are, however, sparse. The effect of the clinically used copper chelator D-penicillamine in the catecholamine model of acute myocardial injury was tested in cardiomyoblast cell line H9c2 and in Wistar Han rats. D-Penicillamine ...
متن کامل[Transient apical dysfunction syndrome (Tako-Tsubo) simulating acute myocardial infarction].
Transient apical dysfunction syndrome (TADS) is frequently misdiagnosed as an acute coronary syndrome (ACS). It is characterized by electrocardiographic alterations and elevated myocardial necrosis markers, accompanied by hypokinesia, akinesia or anteroapical dyskinesia, in absence of significant coronary disorders. It generally resolves in days or weeks with individualized support measures. We...
متن کاملTransient left ventricular systolic dysfunction mimicking myocardial infarction after pericardiocentesis
A 69-year-old woman was admitted to our hospital because of weight loss and progressively worsening dyspnoea. Her previous medical history was unremarkable. She was admitted to the internal medicine department. A cardiologist was consulted because of atrial fibrillation with rapid ventricular response and an enlarged cardiac silhouette on her chest Xray. On physical examination her blood pressu...
