The neutrophil-to-lymphocyte ratio is associated with in-hospital heart failure in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention

Objective: To explore the association between the neutrophil-to-lymphocyte ratio (NLR) and in-hospital heart failure (HF) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods: Our present study included 413 patients diagnosed with STEMI and treated with primary PCI. We performed logistic regression models to evaluate the relationship between the NLR and in-hospital HF risk in subjects diagnosed with STEMI. Results: The incidence of HF after STEMI increased significantly with increasing NLR tertiles (the incidences of the first, second, and third tertiles were 5.07 %, 13.04 %, and 23.36 %, respectively; P
