摘要

We assessed the prognostic value of the platelet to lymphocyte ratio (PLR) in primary percutaneous coronary intervention (pPCI). Patients (n = 440) with acute myocardial infarction (AMI) who underwent pPCI were divided into 2 groups: low PLR (5137) and high PLR (4137). "Thrombolysis In Myocardial Infarction'' (TIMI) flow grades and Syntax scores (SXS) were calculated from initial angiograms. In-hospital mortality rate and cardiac adverse events were obtained from medical records. Patients with high PLR had more no-reflow, higher SXS and higher mortality rate (p<0.001, p<0.001 and p = 0.008, respectively). In receiver operating characteristic curve analysis, high PLR predicted development of no-reflow (specificity 71% and sensitivity 85%), SXS422 (specificity 52% and sensitivity 61%) and adverse events (specificity 67% and sensitivity 63%). In multivariate regression analysis, PLR was an independent risk factor for no-reflow, SXS422 and in-hospital adverse events. In addition to PLR, we present the relationship between mean platelet volume, red cell distribution width and neutrophil to lymphocyte ratio and no-reflow, SXS and in-hospital adverse events.
