OBJECTIVE: The role of inflammatory markers as neutrophil-to-lymphocyte ratio (NLR), monocyte-to-high-density lipoprotein-cholesterol ratio (MHR), and platelet-to-lymphocyte ratio (PLR) in cardiovascular diseases has been widely investigated in recent years. In the context of lower extremity arterial disease (LEAD), this association has been mainly studied in the advanced stages. The aim of our study was to investigate the role of these inflammatory markers in all stages of LEAD, including early ones, using ultrasonography as diagnostic tool, together with ankle-brachial index (ABI) determination.

PATIENTS AND METHODS: In this cross-sectional observational study, we enrolled 240 patients undergoing ultrasonographic evaluation of the lower limb arteries and ABI determination because of symptoms suggestive of LEAD or presence of known cardiovascular risk factors.

RESULTS: In our study population, we found that ultrasonographic categories of LEAD were associated with NLR, but not with MHR and PLR.

CONCLUSIONS: These results confirm that a specific pattern of inflammation can be found in all stages of LEAD, including early ones.
