All scale is 0 - No symptoms, 1 - No significant disability, 2 - Slight disability, 3 - Moderate disability, 4 - Moderately severe disability, 5 - Severe disability, 6 - Dead.

    within 90 days after fibrinolysis

Secondary Outcomes (6)

  • Surgery on the brain or spinal cord.
  • Suspicion of subarachnoid hemorrhage.
  • Signs of severe stroke: clinical signs (stroke scale NIH\> 25), neuroimaging (according to CT of the brain and / or MRI of the brain in the DWI, the ischemia focuses on the territory of more than 1/3 of the CMA pool).
  • Simultaneous reception of oral anticoagulants, for example, warfarin with INR\> 1.3.
  • The use of direct anticoagulants (heparin, heparinoids) in the preceding stroke of 48 h with APTT values above the norm.
  • Prior stroke or severe head injury within 3 months.
  • Significant regression of neurological symptoms during the observation of the patient.(Version 1.0)
  • Light neurological symptoms (NIH \<4 points). (Version 1.0)
  • Significant regression of neurological symptoms during the observation of the patient before thrombolisis (Version 2.0)
  • Hemorrhagic stroke or stroke, unspecified in history.
  • Strokes of any genesis in the history of a patient with diabetes mellitus.
  • +16 more criteria
