Neutrophil/Lymphocyte (N/L) Ratio and Long Term Follow-up in ST-elevation Myocardial Infarction

Although the pre-procedural neutrophil to lymphocyte ratio (N/L) has been associated with adverse outcomes among patients with coronary artery disease, its role during the acute phase of ST-segment elevation myocardial infarction (STEMI) has not been fully investigated. This study sought to investigate the association of the pre-procedural N/L ratio within-hospital and long-term outcomes among STEMI patients undergoing primary percutaneous coronary intervention (PCI).
