Neutrophil-to-high-density lipoprotein ratio: an independent predictor of infarct-related artery patency in patients with acute myocardial infarction

Abstract

Aims: The definition of an infarct-related artery (IRA) is a coronary artery occluded by a thrombus or atheroma that causes ischemia during acute myocardial infarction (AMI). Early patency of the IRA is the primary goal of treatment in patients with AMI. The neutrophil/ high-density lipoprotein cholesterol (HDL-C) ratio (NHR) has been recognized as a new inflammatory marker. We aimed to show the possible relationship between NHR and preprocedural IRA patency. Methods: Four hundred patients were screened, and 318 were included in the study after exclusion criteria. IRA flow rate before the coronary procedure was determined according to the previously described thrombolysis in myocardial infarction (TIMI). TIMI current 0,1 and 2 patients were considered IRA non-patent, and TIMI-3 patients were considered IRA patent and were divided into two groups. Regression analysis was performed for possible parameters in predicting IRA patency, evaluated in univariable analysis, and those with p-value
