Background and Purpose— There is uncertainty among many emergency medicine physicians about the decision to give intravenous tPA (tissue-type plasminogen activator), which limits its use. A checklist approach has been suggested as a solution. We compared agreement on tPA treatment in suspected acute ischemic stroke patients between emergency medicine residents (EMRs) using a checklist and vascular neurology fellows (VNFs). Methods— Every suspected acute stroke patient brought to our comprehensive stroke center emergency room within 4.5 hours from symptom onset was prospectively evaluated simultaneously and independently by VNFs and EMRs. The latter used a tPA screening checklist, which included guideline exclusion criteria to help with their treatment decision. Agreement was determined using kappa (k) statistics. Results— Over 6 months, 60 patients were enrolled; 10% large vessel atherosclerosis, 18% cardioembolism, 12% small vessel, 12% cryptogenic, and 47% mimic. Forty-two percent were deemed tPA eligible by the EMR, 30% by the VNF, and 37% by the vascular neurology faculty. There were no complications in any tPA-treated patients. Agreement was substantial between EMR and VNF (κ=0.68 [95% CI, 0.49–0.87]) and between EMR and vascular neurology faculty (κ=0.69 [95% CI, 0.50–0.87]). Stroke mimics were the main cause of disagreement between EMR and VNF (κ=0.24 [95% CI, −0.15 to 0.63]) and between EMR and vascular neurology faculty (κ=0.35 [95% CI, −0.08 to 0.78]). Conclusions— Our data suggest that with the aid of a checklist, EMRs can accurately treat stroke patients with tPA. Areas for improvement include recognition of stroke mimics. Further studies are warranted to evaluate checklist-enhanced tPA treatment to allay emergency medicine physician uncertainty and expand the use of tPA.

Abstract Background Thrombolysis with tissue-type plasminogen activator (IV-tPA) is a well-proved, widely used treatment in acute ischemic stroke patients, many predictors of functional outcome have been proposed as Age, vascular risk factors, initial clinical evaluation on admission using National institute of health stroke scale(NIHSS), functional state of patient(b.L) baseline before stroke and 3 months (3m) after stroke using modified Rankin stroke scale (MRS)and the most controversial Diffusion weighted image characteristics (volume, heterogeneity) Objective To evaluate DWI MRI characteristics (volume, heterogeneity) as a predictor for outcome in Acute stroke patients treated by IV-tPA Patients and Methods This study will be done on a sample of 100 acute ischemic stroke Egyptian patients receiving intra-venous tissue -type plasminogen activator presenting to Ain-Shams university hospitals Results Highly statistically significant (p-value < 0.001) Positive correlation (r = 0.394) between volume (DWI) and MRS (3m) post discharge in studied patients, No statistically significant (pvalue > 0.05) relation between heterogeneity and other studied parameters (MRS, NIHSS D & ADC values) in studied patients Conclusion DWI infarct volume is a predictor for outcome in acute ischemic stroke patients treated by tPA

Higher body temperature is a prognostic factor of poor outcome in acute stroke. Our aim was to study the relationship between body temperature, HT (haemorrhagic transformation) and biomarkers of BBB (blood–brain barrier) damage in patients with acute ischaemic stroke untreated with rtPA (recombinant tissue-type plasminogen activator). We studied 229 patients with ischaemic stroke <12 h from symptom onset. Body temperature was determined at admission and every 6 h during the first 3 days. HT was evaluated according to ECASS II (second European Co-operative Acute Stroke Study) criteria in a multimodal MRI (magnetic resonance imaging) at 72 h. We found that 55 patients (34.1%) showed HT. HT was associated with cardioembolic stroke (64.2% against 23.0%; P<0.0001), higher body temperature during the first 24 h (36.9°C compared with 36.5°C; P<0.0001), more severe stroke [NIHSS (National Institutes of Health Stroke Scale) score, 14 (9–20) against 10 (7–15); P=0.002], and greater DWI (diffusion-weighted imaging) lesion volume at admission (23.2 cc compared with 13.2 cc; P<0.0001). Plasma MMP-9 (matrix metalloproteinase 9) (187.3 ng/ml compared with 44.2 ng/ml; P<0.0001) and cFn (cellular fibronectin) levels (16.3 μg/ml compared with 7.1 μg/ml; P=0.001) were higher in patients with HT. Body temperature within the first 24 h was independently associated with HT {OR (odds ratio), 7.3 [95% CI (confidence interval), 2.4–22.6]; P<0.0001} after adjustment for cardioembolic stroke subtype, baseline NIHSS score and DWI lesion volume. This effect remained unchanged after controlling for MMP-9 and cFn. In conclusion, high body temperature within the first 24 h after ischaemic stroke is a risk factor for HT in patients untreated with rtPA. This effect is independent of some biological signatures of BBB damage.
