Abstract 4148181: Neutrophil and Leucocyte Ratio and LDL to HDL ratios as predictors of Hemorrhagic transformation in ischemic stroke patients : A systematic review

Circulation

NOVEMBER 11, 2024

Background:Following an ischemic stroke, a serious complication known as hemorrhagic transformation (HT) might jeopardize patient outcomes. Following an ischemic stroke, an increased incidence of HT, especially parenchymal hematoma (PH), has been associated with greater NLR.
