Abstract:Inflammation in the arterial circulation is considered to be a risk factor for the development of atherosclerotic plaques. In the last several decades, attempts have been made to quantify the degree of ongoing inflammation through measurement of serum biochemical markers. Neutrophil/lymphocyte ratio as an effective inflammatory predictor in lower extremity arteriosclerosis obliterans (ASO) has attracted more and more attention. Appropriate application of biomarkers in patients with ASO may contribute to an early diagnosis, a better understanding of disease progression, as well as to the subsequent improvement of current therapies and development of new ones.
