Abstract

Objective. The aim of the present study was to investigate the predictive value of neutrophil count for no-reflow in patients with ST-segment elevation myocardial infarction (STEMI) who underwent successful primary percutaneous intervention (PCI). Methods. We conducted a retrospective study of 361 patients diagnosed with acute STEMI between 2011 and 2015. All patients underwent successful PCI within 12 h from the onset of symptoms. Angiographic no-reflow was diagnosed based on a post-PCI thrombolysis in myocardial infarction flow grade ≤ 2 without mechanical obstruction. According to a neutrophil count cut-off determined by receiver operating characteristic curve analysis, patients were divided into two groups: group A (neutrophil count < 9.14 × 109/L) and group B (neutrophil count ≥ 9.14 × 109/L). Results. Compared to patients in the normal reflow group, patients with no-reflow had higher neutrophil counts (). The incidence rate of no-reflow in group A (18, 9.3%) was significantly lower than that in group B (38). Multivariate logistic regression analysis revealed that a neutrophil count ≥ 9.14 × 109/L was independently predictive for no-reflow (odds ratio = 4.474, 95% confidence interval: 1.610–12.433, ) after adjusting for potential confounders. Conclusions. A circulating neutrophil count ≥ 9.14 × 109/L is independently associated with no-reflow in patients with acute STEMI following primary PCI.
