Abstract Peripheral vascular disease (PVD) carries a significant morbidity and mortality. The role of inflammatory markers in cardiovascular medicine has been extensively studied. Neutrophil Lymphocyte ratio (NLR) is a novel biomarker which has been proposed as a marker of cardiovascular disease. We review the association of NLR with PVD. NLR has been shown to be an independent predictor of early and midterm amputation in patients with acute limb ischemia after embolectomy. A recent risk stratification model including NLR has emerged as a predictor of mortality and/or major amputation in critical limb ischemia. NLR appears to be an independent predictor of severity of PVD based on TransAtlantic Inter-Society Consensus classification, which classifies PVD based on the nature of the lesion and its anatomic distribution. A review of a large cohort of patients who had major vascular surgery, an NLR > 5 was found to be an independent predictor of mortality. In patients with intermediate carotid artery disease, NLR of 2.6 was found to be an independent variable for symptomatic carotid artery disease. It is a good predictor of early death in acute pulmonary embolism. NLR is inexpensive and readily available and appears to have a major role in peripheral vascular disease.
