To best of our knowledge this is the first study about relationship between FMD response (impaired endothelial response) and blood parameters in patients with pRP. On the other hand this is the first report about relationship between impaired endothelial response and MCP-1 levels in pRP. Our results indicated that patients with pRP have higher impaired endothelial to ischemia. The incremental levels of serum WBC, MPV, MCP-1 and fibrinogen values were detected in pRP group. Moreover, moderate direct correlation was found between abnormal FMD response and serum MCP-1 values.
