Predictors of the functional outcome after thrombolysis in an Egyptian patients' sample

BackgroundAbout 6.2 million individuals worldwide and approximately 200 Egyptians/100,000 citizens have cerebrovascular stroke annually, and only less than 1% of stroke patients received intravenous (IV) thrombolysis in 2014. Outcome of the ischemic stroke after IV thrombolysis varies, and there is lack of data about the predicting factors that contributes to the outcome of ischemic strokes after IV thrombolysis in Egypt.ObjectiveThe aim of this work is to study the predictors of the functional outcome of ischemic cerebrovascular stroke after IV thrombolysis in Egyptian patients.Patients and methodsThis is a prospective study that includes acute ischemic stroke patients who received IV thrombolysis at the Alexandria University Hospital during the year from February 2017 to February 2018, and they were evaluated initially by Rapid Arterial Occlusion Evaluation (RACE) scale and followed-up serially for 6months after thrombolysis using the National Institutes of Health Stroke Scale (NIHSS) and modified ranking score (mRS).ResultsForty-five patients are included; 56% had favorable functional outcome (mRS 0-2) after 6months, 68% had >= 4 points improvement in NIHSS after 6months, and 13% had hemorrhagic conversion with 18% mortality rate. High initial RACE scale and long hospital stay are associated with poor functional outcome 6months after thrombolysis.ConclusionStroke severity demonstrated by high initial RACE and the duration of hospital stay are the two most significant predictors with an impact on the functional outcome of ischemic cerebrovascular stroke after thrombolysis.
