Abstract
Background Congestive heart failure (CHF) is associated with altered energy homeostasis and myocardial inflammation, hypertrophy, and fibrosis. Adiponectin, an insulin-sensitizing adipocytokine, may affect these pathogenic factors, and the circulating adiponectin level may serve as a biological marker of CHF. This study aimed to assess the significance of serum adiponectin as a prognostic marker for Japanese CHF patients. Methods and Results The serum adiponectin levels were compared between 54 (24 ischemic and 30 non-ischemic) CHF patients with left ventricular systolic dysfunction and 55 age- and gender-matched control subjects. The CHF patients also underwent simultaneous clinical assessment and measurements for brain natriuretic peptide (BNP) and parameters of lipid or glucose metabolism. Compared with the controls, the CHF patients showed significantly increased serum adiponectin levels [6.7 (4.9-12.6) vs 14.6 (9.7-25.4) μg/ml, pCirc J 2007; 71: 623 - 630)
