Abstract Objective To explore the change of serum adiponectin (APN) concentration in patients with coronary slow flow(CSF) phenomenon and the relationship between serum APN and coronary flow. Methods 206 cases without coronary artery disease and other heart diseases were divided into CSF group(n=106) and control group(n=100) based on TIMI frame count(TFC). Serum APN was measured by enzyme- linked immunosorbent assay. The relationship between serum APN and TFC was evaluated. Results The serum APN concentration was significantly lower in CSF group than in control group [ (8.2±2.74)mg/L vs.(11.3±3.0)mg/L, P<0.01]. TFC was negatively correlated with serum APN(r=- 0.56, P<0.01). The ratios of hypertension and smoking were significantly higher in CSF group than in control group (al P<0.05). Conclusion There is an obvious correlation between serum APN concentration and CSF. Hypertension and smoking are also associated with CSF.
