Adiponectin resistance in heart failure and the emerging pattern of metabolic failure in chronic heart failure

In recent years, an interesting shift in our understanding of chronic heart failure (CHF) pathophysiology may be observed. Beyond the traditional concepts of hemodynamic failure and neuroendocrine activation, it is increasingly appreciated that CHF is a much more complex and truly systemic disease including the peripheral organs and whole body regulatory processes as well. Novel concepts such as the systemic inflammatory immune activation and the skeletal muscle hypothesis have emerged.1 These concepts recognize the significant contribution of peripheral changes to symptomatic status, disease progression, and outcome in CHF.
