Association of anemia and hemoglobin decrease during acute stroke treatment with infarct growth and clinical outcome.

Background And Purpose: Anemia is associated with worse outcome in stroke, but the impact of anemia with intravenous thrombolysis or endovascular therapy has hardly been delineated. The aim of this study was to analyze the role of anemia on infarct evolution and outcome after acute stroke treatment.

Methods: 1158 patients from Bern and 321 from Los Angeles were included.
