CXCL8 and congestive heart failure: The evaluation of BCS and MMS is important in heart disease patients, since the presence of congestive heart failure (CHF) associated to MMVD changes of inflammatory cytokines (TNF-α, IL-1, IL-6, IL-8, chemokines, catecholamines, cortisol and others) induce an inflammatory state and decreases the body’s ability to make metabolic adaptations [18] and use amino acids as a source of energy, causing muscle catabolism that results in the loss of lean mass and the development of cardiac cachexia [4].
