Objective: Adropin is a recently identified bioactive protein that is important for energy homeostasis and maintaining insulin sensitivity. We sought to detect serum adropin levels in acute myocardial infarction (AMI) patients.
Methods: We enrolled 138 AMI patients, 114 stable angina pectoris (SAP) patients and 75 controls. Adropin levels were measured by enzyme-linked immunosorbent assay (ELISA).
Results: Serum adropin levels were significantly lower in patients with AMI compared with SAP patients or controls (P<0.01). Multivariate logistic regression demonstrated that lower adropin was the independent predictor for the presence of AMI in coronary artery disease (CAD) patients (P<0.01). Serum adropin levels were negatively associated with body mass index (BMI) (P<0.01) and triglyceride levels (P<0.05) in AMI patients.
Conclusion: Decreased serum adropin levels are associated with the presence of AMI in CAD patients. These results revealed that adropin might represent as a novel biomarker for predicting AMI onset in CAD patients.
