1.She would have been considered at low risk of stroke within 48 hrs of symptom onset 0 32 0 The risk of stroke following a TIA is significant, with a recent meta analysis reporting a 9.9 % risk of stroke after 2 days. [20]
2.Duration of symptoms does not contribute to risk 10 21 1 Factors that influence the risk of stroke include age, blood pressure, specific clinical features, presence of diabetes, duration of symptoms, aetiology of index event (e.g. atrial fibrillation), frequency of TIA symptoms, history of previous TIAs and smoking.
3.Limb weakness increases stroke risk 24 3 5
4.BP contributes to risk of stroke in next 48 hrs 26 2 4 Johnston et al devised and validated a unified ABCD2 score to predict the risk of stroke after TIA at 2 days [21].
