Neutrophil/Lymphocyte Ratio as a Predictor of In-Hospital Major Adverse Cardiac Events, New-Onset Atrial Fibrillation, and No-Reflow Phenomenon in Patients with ST Elevation Myocardial Infarction

Abstract

Older patient age, longer pain-to-balloon time, hyperglycemia, higher N/L ratio, and MPV on admission are useful predictive factors for the occurrence of no-reflow postprimary percutaneous coronary intervention, NOAF, and/or in-hospital MACE. N/L ratio is a new strong independent predictor of no-reflow, NOAF, and/or in-hospital MACE in patients with STEMI. The use of this simple routine biomarker may have a potential therapeutic implication in preventing NOAF and improving prognosis in STEMI revascularized patients.
