Impact of Statin Use and Lipid Profile on Symptomatic Intracerebral Haemorrhage, Outcome and Mortality after Intravenous Thrombolysis in Acute Stroke

ObjectivesThe aim of this study was to evaluate the effect of alteplase in intravenous thrombolysis of acute ischaemic stroke (AIS) regarding the different time windows of treatment (<3 hours, 3–4.5 hours, >4.5 hours).MethodsA systematic literature search was conducted from PubMed, Cochrane Library and Embase. 12 clinical randomised controlled trials with 3402 patients with AIS met the inclusion criteria. The primary, secondary and tertiary outcomes were modified Rankin Scale (mRS) scores 0–1, mortality at 90th day after treatment and symptomatic intracerebral haemorrhage within 36 hours, respectively. Network meta-analysis and conventional meta-analysis were carried out for calculating odds ratio (OR), the surface under cumulative ranking curve (SUCRA) and the probabilities of being the best.ResultsFor mRS, alteplase regardless of time delay was significantly more effective than placebo (OR 1.33–2.17). However, alteplase used within 3 hours after AIS occurrence (SUCRA=98.3%) was significantly more effective (OR=1.64) than that at 3–4.5 hours (SUCRA=43%) and showed the trend of priority (OR=1.47) compared with that beyond 4.5 hours (SUCRA=58%). For the mortality, compared with placebo (SUCRA=64.7%), alteplase within 3 hours was similar to that of 3–4.5 hours whereas alteplase beyond 4.5 hours (SUCRA=7.3%) showed the trend of significantly increasing 85% mortality. For the tertiary outcome, alteplase within 3 hours (SUCRA=19.0%) was comparable with placebo (SUCRA=99.9%) whereas alteplase beyond 3 hours significantly increased (OR 5.89–6.67) the symptomatic intracerebral haemorrhage.ConclusionsAlteplase within 3 hours should be recommended as the best treatment delay for its best efficacy among all the intervention and equivalent safety compared with placebo. Alteplase beyond 3 hours was less effective compared with that within 3 hours and increased the risk of mortality on 3 months as well as symptomatic intracerebral haemorrhage at 36 hours. More head-to-head clinical trials are needed to confirm those findings.

IntroductionMechanical thrombectomy (MT) increases functional independence in patients with acute ischaemic stroke with anterior circulation large vessel occlusion (LVO), and the probability to achieve functional independence decreases by 20% for each 1-hour delay to reperfusion. Therefore, we aim to investigate whether direct angiosuite transfer (DAT) is superior to standard imaging/emergency department-based management in achieving 90-day functional independence in patients presenting with an acute severe neurological deficit likely due to LVO and requiring emergent treatment with MT.Methods and analysisDIRECT ANGIO (Effect of DIRECT transfer to ANGIOsuite on functional outcome in patient with severe acute stroke treated with thrombectomy: the randomised DIRECT ANGIO Trial) trial is an investigator-initiated, multicentre, prospective, randomised, open-label, blinded endpoint (PROBE) study. Eligibility requires a patient ≤75 years, pre-stroke modified Rankin Scale (mRS) 0–2, presenting an acute severe neurological deficit and admitted within 5 hours of symptoms onset in an endovascular-capable centre. A total of 208 patients are randomly allocated in a 1:1 ratio to DAT or standard management. The primary outcome is the rate of patients achieving a functional independence, assessed as mRS 0–2 at 90 days. Secondary endpoints include patients presenting confirmed LVO, patients eligible to intravenous thrombolysis alone, patients with intracerebral haemorrhage and stroke-mimics, intrahospital time metrics, early neurological improvement (reduction in National Institutes of Health Stroke Scale by ≥8 points or reaching 0–1 at 24 hours) and mRS overall distribution at 90 days and 12 months. Safety outcomes are death and intracerebral haemorrhage transformation. Medico-economics analyses include health-related quality of life and cost utility assessment.Ethics and disseminationThe DIRECT ANGIO trial was approved by the ethics committee of Ile de France 1. Study began in April 2020. Results will be published in an international peer-reviewed medical journal.Trial registration numberNCT03969511.

Introduction: We analyzed whether the coronavirus disease 2019 (COVID-19) crisis affected acute stroke care in our center during the first 2 months of lockdown in Spain. Methods: This is a single-center, retrospective study. We collected demographic, clinical, and radiological data; time course; and treatment of patients meeting the stroke unit admission criteria from March 14 to May 14, 2020 (COVID-19 period group). Data were compared with the same period in 2019 (pre-COVID-19 period group). Results: 195 patients were analyzed; 83 in the COVID-19 period group, resulting in a 26% decline of acute strokes and transient ischemic attacks (TIAs) admitted to our center compared with the previous year (p = 0.038). Ten patients (12%) tested positive for PCR SARS-CoV-2. The proportion of patients aged 65 years and over was lower in the COVID-19 period group (53 vs. 68.8%, p = 0.025). During the pandemic period, analyzed patients were more frequently smokers (27.7 vs. 10.7%, p = 0.002) and had less frequently history of prior stroke (13.3 vs. 25%, p = 0.043) or atrial fibrillation (9.6 vs. 25%, p = 0.006). ASPECTS score was lower (9 [7–10] vs. 10 [8–10], p = 0.032), NIHSS score was slightly higher (5 [2–14] vs. 4 [2–8], p = 0.122), onset-to-door time was higher (304 [93–760] vs. 197 [91.25–645] min, p = 0.104), and a lower proportion arrived within 4.5 h from onset of symptoms (43.4 vs. 58%, p = 0.043) during the COVID-19 period. There were no differences between proportion of patients receiving recanalization treatment (intravenous thrombolysis and/or mechanical thrombectomy) and in-hospital delays. Conclusion: We observed a reduction in the number of acute strokes and TIAs admitted during the COVID-19 period. This drop affected especially elderly patients, and despite a delay in their arrival to the emergency department, the proportion of patients treated with recanalization therapies was preserved.

Abstract Purpose Mechanical thrombectomy (MT) is the first-line treatment in acute stroke patients presenting with large vessel occlusion (LVO). The efficacy of intravenous thrombolysis (IVT) prior to MT is being contested. The objective of this study was to evaluate the efficacy of MT without IVT in patients with no contraindications to IVT presenting directly to a tertiary stroke center with acute anterior circulation LVO. Materials and Methods We collected the data of 106 acute stroke patients who underwent MT in a single high-volume stroke center. Patients with anterior circulation LVO eligible for IVT and directly admitted to our institution who subsequently underwent MT were included. We recorded baseline clinical, laboratory, procedural, and imaging variables and technical, imaging, and clinical outcomes. The effect of intravenous thrombolysis on 3-month clinical outcome (mRS) was analyzed with univariate tests and binary and ordinal logistic regression analysis. Results Fifty-eight out of the 106 patients received IVT + MT. These patients had 2.6-fold higher odds of poorer clinical outcome in mRS shift analysis (p = 0.01) compared to MT-only patients who had excellent 3-month clinical outcome (mRS 0–1) three times more often (p = 0.009). There were no significant differences between the groups in process times, mTICI, or number of hemorrhagic complications. A trend of less distal embolization and higher number of device passes was observed among the MT-only patients. Conclusions MT without prior IVT was associated with an improved overall three-month clinical outcome in acute anterior circulation LVO patients.

Introduction: The endovascular treatment (EVT) of cerebral ischemia in the case of large vessel occlusion has been established over recent years. Randomized trials showed a positive impact on the clinical outcome of endovascular treatment in addition to thrombolysis with respect to clinical outcome and safety, so that this therapeutic option will be implemented in future guidelines. The role of EVT in patients treated with oral anticoagulants remains uncertain. Hypothesis: We assessed the hypothesis that application of EVT is safe with regard to the occurrence of intracranial bleeding and clinical outcome in patients taking anticoagulants. Methods: The ENDOSTROKE-Registry is a commercially independent, prospective observational study in 12 stroke centers in Germany and Austria launched in January 2011. An online tool served for data acquisition of pre-specified variables concerning endovascular stroke therapy. Results: Data from 815 patients (median age 70, 57% male) undergoing EVT and known anticoagulation status were analyzed. A total of 85 (median age 76, 52% male) patients (10.4%) took oral anticoagulants prior to EVT. Anticoagulation status as measured with INR was 2.0-3.0 in 24 patients (29%), <2.0 in 52 patients (63%) and above 3.0 in 7 patients (8%) of 83 patients with valid INR data prior to EVT. Patients taking anticoagulants were significantly older (median age 76 vs. 69, p < 0.001). Comparing those patients taking anticoagulants and those not, there were no differences concerning NIHSS at admission (with anticoagulants Median-NIHSS 17 vs. without Median-NIHSS 15, p = 0.492, Mann Whitney Test) and the rate of intracranial hemorrhage after intervention (with anticoagulants 11.8% vs. without 12.2%, p = 0.538). After adjustment for age and NIHSS at admission there were no significant differences between the two groups with regard to good clinical outcome, as measured with the modified ranking scale (mRS, 90d-mRS 0-2, 39.2% of patients not receiving anticoagulants; 25.9% of those receiving anticoagulants). Conclusion: The application of endovascular treatment in patients taking oral anticoagulants is safe and should be considered in acute stroke treatment as an important alternative to contraindicated intravenous thrombolysis.

Objective: To use the Computed Tomography Perfusion (CTP) parameters at the time of hospital admission, including Cerebral Blood Volume (CBV) and Permeability Surface area product (PS), to identify patients with higher risk to develop hemorrhagic transformation in the setting of acute stroke therapy with intravenous thrombolysis. Methods: Retrospective study that compared admission CTP variables between patients with Hemorrhagic Transformation (HT) acute stroke and those with no hemorrhagic transformation. Both groups received standard of care intravenous thrombolysis with tPA. Twenty patients presented to our stroke center between the years 2007 - 2011 within 3 hours after stroke symptoms onset. All patients underwent two-phase 320 slice CTP which creates CBV and PS measurements. Patients were divided into two groups according to whether or not they had HT on a follow up CT head without contrast, done within 36 hours of the thrombolysis therapy. Clinical, demographic and CTP variables were compared between the HT and non-HT groups using logistic regression analyses. Results: HT developed in 8 (40%) patients. Patients with HT had lower ASPECT score ( P =.03), higher NIHSS on admission ( P= .01) and worse outcome ( P= .04) compared to patients who did not develop HT. Baseline blood flow defects were comparable between the two groups. The mean PS for the HT group was 0.53 mL/min/100g brain tissue, which was significantly higher than that for the non-HT group of 0.04 mL/min/100g brain tissue ( P <.0001). The mean area under the curve was 0.92 (95% CI). The PS threshold of 0.26 mL/min/100g brain tissue had a sensitivity of 80% and a specificity of 92% for detecting patients with high risk of hemorrhagic transformation after intravenous thrombolysis. Conclusions: Admission CTP measurements might be useful to predict patients who are at higher risk to develop hemorrhagic transformation after acute ischemic stroke therapy.
