Biventricular Tako-Tsubo cardiomyopathy: Usefulness of 2D speckle tracking strain echocardiography
No full textAn echo-guided case report of rapid regression of unstable mobile thrombus aortic atheroma after aggressive statin and antiplatelet combination therapy
No full textWe describe a case report that documented the efficacy and safety of medical therapy in stabilizing and resolving a complex and unstable aortic atheroma after a relatively short period. The patient had a large protruding, mobile, calcified nonulcerated atheroma involving the descending aorta and was therefore treated with aggressive combination therapy with high statin dosages (atorvastatin 5 80 mg) and dual antiplatelet treatment (clopidogrel 5 75 mg and aspirin 5 100 mg). At follow-up, the echocardiogram showed a significant regression in the atheroma volume, with no signs suggestive of ulceration on its surface with the complete mobile component resolution. © 2013 Lippincott Williams & Wilkins
Renal dysfunction in acute heart failure: epidemiology, mechanisms and assessment
No full textRenal dysfunction is often present and/or worsens in patients with heart failure and this is associated with increased costs of care, complications and mortality. The cardiorenal syndrome can be defined as the presence or development of renal dysfunction in patients with heart failure. Its mechanisms are likely related to low cardiac output, increased venous congestion and renal venous pressure, neurohormonal and inflammatory activation and local changes, such as adenosine release. Many drugs, including loop diuretics, may contribute to worsening renal function through the activation of some of these mechanisms. Renal damage is conventionally defined by the increase in creatinine and blood urea nitrogen blood levels. However, these changes may be not related with renal injury or prognosis. New biomarkers of renal injury seem promising but still need to be validated. Thus, despite the epidemiological evidence, we are still lacking of satisfactory tools to assess renal injury and function and its prognostic significance

Can we prevent or treat renal dysfunction in acute heart failure?
No full textMost patients with heart failure (HF) already have or develop renal dysfunction; this might contribute to their poor outcome. Current treatment for HF can also contribute to worsen renal function. High furosemide doses are traditionally associated with worsening renal function (WRF), but patients with fluid overload may benefit of aggressive fluid removal. Unfortunately, promising therapies like vasopressin antagonists and adenosine antagonists have not been demonstrated to improve outcomes. Likewise, correction of low renal blood flow through dopamine, inotropic agents, or vasodilators does not seem to be associated with a clear benefit. However, transient WRF associated with acute HF treatment may not necessarily portend a poor prognosis. In this review, we focus on the strategies to detect renal dysfunction in acute HF, the underlying pathophysiological mechanisms, and the potential treatments

Brugada syndrome phenotype cardiac arrest in a young patient unmasked during the acute phase of amiodarone infusion: Disclosure and aggravation of Brugada electrocardiographic pattern
No full textWe report a case of an outpatient cardiac arrest due to ventricular fibrillation and resuscitated with external automated defibrillator shocks in which acute amiodarone infusion unmasked a Brugada phenotype electrocardiographic pattern. Possible interferences by this drug and suitable therapeutic actions are discussed. © 2012 Elsevier Inc. All rights reserved
