Abstract:
BACKGROUND:Although several clinical studies have evaluated plasma adiponectin levels in response to chronic heart failure, little is known about the relation between cardiac function and metabolic factors including adiponectin in patients with acute myocardial infarction (AMI). METHODS AND RESULTS:We analyzed 50 consecutive patients with AMI who had undergone successful coronary stent implantation. Echocardiography and blood sampling were performed at 1 week and 6 months after AMI. Blood was analyzed with regard to brain natriuretic peptide (BNP) and metabolic factors including plasma levels of adiponectin, lipid profile, and hemoglobin A1c (HbA1c). Plasma adiponectin levels were significantly increased at 6 months (7.3 ± 4.9 μg/ml) compared to those at 1 week (6.1 ± 3.7). BNP (from 156 ± 151 to 96 ± 124 pg/ml) significantly decreased. In addition, BNP at 6 months was positively correlated with plasma adiponectin levels at 1 week (y = 0.019 x -23.1, r = 0.537, P = 0.002), while BNP at 6 months was not associated with maximal creatinine kinase after AMI. A multiple regression analysis was performed to analyze the relationship between BNP at 6 months and metabolic factors (plasma levels of adiponectin, lipid profile, HbA1c, blood pressure, age, sex, and body mass index) at 1 week after AMI. BNP at 6 months was most closely correlated with plasma levels of adiponectin at 1 week (P = 0.045). CONCLUSIONS:Among the metabolic factors examined, a higher adiponectin level at 1 week is the predictor of a higher BNP as one marker of cardiac dysfunction at 6 months after AMI.
