Cardiac cachexia as a terminal stage of chronic heart failure carries a devastating prognosis. This article focuses on novel insights into the pathophysiology and on new treatment approaches to cardiac cachexia. Drugs that have been used in preclinical and clinical studies that may also confer beneficial effects in cardiac cachexia include but are not limited to the type 4 melanocortin receptor antagonist SNT 207979, the appetite promoting synthetic ghrelin SUN11031, the soluble myostatin decoy receptor ActRIIB-Fc, the fast skeletal muscle troponin activating substance CK-2017357, the anti-catabolic/anabolic transforming agent MT-102, the anti-inflammatory agent celecoxib, and testosterone supplementation.

Usefulness of left atrial volume for the diagnosis of diastolic heart failure: an echocardiographic-catheterization study.
The present study attempted to determine the accuracy of left atrial volume (LAVi) by transthoracic echocardiography in the diagnosis of diastolic heart failure (DHF) in patients presenting with chronic, isolated dyspnea. We included 28 consecutive patients with a left ventricular ejection fraction >50% without prior history of heart failure. ⋯ LAVi>38 ml/m(2) was a useful predictor of DHF (area under the ROC curve of 0.84 [0.65-0.95], p<0.001, sensitivity 60%, specificity 100%). The standard cut-off value of 34 ml/m(2) was 70% sensitive and 88% specific.

Takotsubo cardiomyopathy in a patient with Addison disease.
Transient left ventricular apical ballooning syndrome, also known as Takotsubo Cardiomyopathy (Broken Heart Syndrome) is increasingly being reported in the medical literature. Its clinical picture resembles of an acute coronary syndrome with transient apical dyskinesia and normal coronary arteries. We report here a case of Takotsubo cardiomyopathy in a patient with Addison disease with reversible cardiomyopathy. To the best of our knowledge there has been only one other reported case of this syndrome with Addison disease but with a different outcome.
