GHRL and cardiovascular disorder: Based on its actions in maintaining energy homeostasis and promoting adipogenesis and muscle function, ghrelin/ghrelin-receptor agonist therapy is considered to have promising potential for restoring energy homeostasis in conditions such as eating/wasting disorders and cachexia related to cancer and other conditions, such as cardiovascular disease and chronic obstructive pulmonary disease (Nagaya et al. 2004, 2005, Strasser et al. 2008, Müller et al. 2010, Ali et al. 2013, Garcia et al. 2015).
