Recurrent ischaemic stroke, sICH, systemic embolism and all-cause mortality at 30 days
  • *Infarct size classified as minor (<1.5 cm diameter), moderate (cortical superficial branch of ACA, MCA or PCA, deep MCA branch, internal borderzone territory or multiple minor lesions) or major (complete ACA, MCA, or PCA, or multiple branches of ACA, MCA or PCA, or multiple arterial territories, or posterior circulation lesion ≥1.5 cm diameter).

  • ACA, anterior cerebral artery; AF, atrial fibrillation; HT, Haemorrhagic transformation; ICH, intracerebral haemorrhage; MCA, middle cerebral artery; NIHSS, National Institutes of Health Stroke Scale; NOACs, non-vitamin K oral anticoagulants; PCA, posterior cerebral artery.
