Reasons and predictors of non‐thrombolysis in patients with acute ischemic stroke admitted within 4.5 h

Abstract

A large proportion of patients with AIS do not receive thrombolysis. This study highlights up-to-date findings that arriving late in the time window, mild symptoms, and previous stroke are strong predictors of non-treatment. It is uncertain whether there is an underuse of thrombolysis in AIS. Increasing the utility of thrombolysis in the 4.5 h time window must be weighed against possible harms.
