What is the conclusion of the 2018 AHA systematic review on the accuracy of prediction instruments for diagnosing LVO in patients with suspected stroke?
The 2018 AHA systematic review concluded that no scale predicted LVO with both high sensitivity and high specificity. It was thought that the probability of LVO with a positive LVO prediction test was only 50% to 60%, whereas more than 10% of those with a negative test may have an LVO. This suggests that more effective tools are needed to identify suspected stroke patients with a strong probability of LVO.
