title: Metabolism and the heart: an overview of muscle, fat, and bone metabolism in heart failure.
abstract: OBJECTIVE
  To review original research studies and reviews that present data on changes of body compartments and its mutual cross-talk with respect to the failing heart predominantly in non-cachectic patients with chronic heart failure (HF).
  
  
  RESULTS
  Thanks to the integrative approach considering the whole organism, several recent studies suggested a complex network of communication between body compartments in respect to failing heart during the natural course of body wasting in non-cachectic patients with HF. Interestingly, recent studies suggest that failing heart trough secretion of natriuretic peptides acts on fat metabolism by inducing adiponectin secretion and lipolytic actions. Soluble myostatin released from the failing heart may induce skeletal muscle wasting in HF through an endocrine-like mechanism, as well. The likelihood that adipocyte-derived hormones influence bone status has been recently proven. Increased serum adiponectin was independently associated with reduced bone mass in elderly patients with non-cachectic HF.
  
  
  CONCLUSIONS
  The concept of body compartments cross-talk in respect to failing heart provides a very interesting paradigm of integrative physiology. Better understanding of body compartments changes and its complex biochemical interplay may provide more efficacious and forehand treatment to prevent and/or postpone disability and improve quality of life in patients with chronic HF.
