Abstract
BackroundWe aimed to evaluate the utility of the preprocedural platelet–lymphocyte ratio (PLR) for predicting the no‐reflow phenomenon after thrombus aspiration during percutaneous coronary intervention (PCI) in patients with ST‐segment elevation myocardial infarction (STEMI).MethodWe retrospectively analyzed postprocedural thrombolysis in myocardial infarction (TIMI) flow grades and myocardial blush grades (MBG) of 247 patients who underwent a PCI procedure with thrombus aspiration.We divided these patients into two groups according to whether they had no‐reflow (TIMI < 3, MBG < 2) or not (TIMI 3, MBG ≥ 2).ResultsNo‐reflow developed in 43 (17%) patients.Preprocedural PLR was significantly higher in the no‐reflow group (183.76 ± 56.65 vs 118.32 ± 50.42 p < 0.001).Independent predictors of no‐reflow were as follows: higher preprocedural platelet‐lymphocyte ratio (PLR) (OR = 1.018; 95% CI = 1.004, 1.033; p = 0.013),mean corpuscular volume (MCV) (OR = 1.118; 95% CI = 1.024, 1.220; p = 0.012) and SYNTAX Score‐2 (OR = 1.073; 95% CI = 1.005, 1.146; p = 0.036). PLR of 144 had 79% sensitivity and 75% specificity for the prediction of no‐reflow.ConclusionPLR is a reliable predictor for no‐reflow in STEMI patients undergoing thrombus aspiration.
