Adiponectin is an adipose tissue-derived plasma protein which has a reduced concentration in subjects with obesity-related diseases. Adiponectin has antidiabetic and anti-inflammatory characteristics, which lead to beneficial actions on various obesity-linked complications. Recent experimental findings have shown that adiponectin contributes to protection against cardiac remodelling after pressure overload and cardiac injury following ischaemia-reperfusion. Thus, adiponectin could emerge as a potential cardioprotective agent for the treatment of several pathological heart conditions.
