High neutrophil-to-lymphocyte ratio (NLR) predicts poor response to intravenous thrombolysis in white Caucasian stroke patients.

Objectives: Our aim was to investigate usefulness of the neutrophil-to-lymphocyte ratio (NLR) for predicting poor response to intravenous rtPA in white Caucasian ischemic stroke patients treated within 4.5 hours from the onset.

Materials And Methods: This retrospective analysis included all consecutive acute ischemic stroke patients (N = 344) treated with rtPA in a tertiary stroke center from 2011 to 2017.
