ASTRAL_Score_for_Ischemic_Stroke_guideline v.1
ASTRAL Score can provide additional information on medium-term functional outcome in patients that have suffered acute ischemic stroke, in addition to clinical judgment based on relevant clinical and laboratory variables. Does not need neuro-imaging data to calculate.Can be used to adjust for functional outcome in multivariate models in acute stroke-related research studies.
Predicts 90-day poor outcome in patients with acute ischemic stroke admitted within 24 hours of stroke onset.
Use in patients with acute ischemic stroke admitted within 24 hours of stroke onset. FORMULA Addition of the selected points: Age=1 point for every 5 years Severity=1 point for every admission NIHSS point Time delay between symptom onset or last proof of good health and admission= 2 points if >3 hours, 0 points if ≤3 hours. Range of visual fields (new visual field defect)=2 points if yes, 0 points if no. Glucose at admission= 1 point if >7.3 or <3.7 mmol/L, 0 points if 3.7-7.3 mmol. Level of consciousness= 3 points if impaired, 0 points if normal. Always use it together with other information that may not be in the score, and Use the score only for patients with pre-stroke independence (Modified Rankin Scale 0-2 points). Patients who were already dependent before the stroke will in general remain so after three months.
Should not be used as a substitute for clinical judgment and is intended for use as an adjunct to medical decision-making. Does not predict mortality or degree of improvement from any form of rehabilitation. Should not be used as a surrogate for stroke severity.
