We hypothesized that the combination of a high neutrophil to lymphocyte ratio (NLR) and mean platelet volume (MPV) would be a stronger predictor of future cardiovascular events after percutaneous coronary intervention (PCI). Both NLR and MPV were measured in 364 consecutive patients undergoing PCI. The primary end point was the incidence of major adverse cardiovascular events (MACEs), including cardiac death, nonfatal myocardial infarction, and stent thrombosis. The median values of NLR and MPV were 2.8 and 8.2 fL, respectively. There were 26 MACEs during a median follow-up duration of 29.3 months. Kaplan-Meier analysis revealed that the higher NLR group had a significantly higher MACE rate than the lower NLR group and that the higher MPV group had a significantly higher MACE rate than the lower MPV group (log-rank: P = .0064 and P = .0004, respectively). The cumulative MACE-free survival can be further stratified by the combination of NLR and MPV. This value was especially useful in patients with acute coronary syndrome (ACS). By multivariate Cox proportional hazards model, the combination of high NLR and high MPV was independently associated with MACE ( P = .026). The combination of a high NLR and high MPV is an independent predictor of MACE after PCI, especially in patients with ACS.
