Background: Neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio
(PLR) have been studied so far as prognostic factors of cardiovascular diseases. Their role interplayed
with endothelial inflammation has emerged as optimal predictors for major cardiovascular
disease events and prognostic factors for post-procedural outcomes.
Methods: A review of the current literature was undertaken to investigate the relationship between
NLR and PLR with percutaneous, cardiac surgery, and vascular surgery procedures.
Results: Our findings show that perioperative NLR and PLR levels are significantly correlated
with patient morbidity and mortality rates.
Conclusion: These biomarkers have several attractive characteristics, as they are inexpensive and
quickly available, and they can contribute to the early identification of patients at high risk for
periprocedural adverse events.
