Prior Use of Statins Improves Outcome in Patients With Intracerebral Hemorrhage. Prospective Data from the National Acute Stroke Israeli Surveys (NASIS)

Background and Purpose— Intracerebral hemorrhage (ICH) is a deadly form of stroke. Pretreatment with statins exerts protective effects in patients with ischemic stroke, but their effects in patients with ICH remains unclear. Methods— The National Acute Stroke Israeli Surveys (NASIS) included all patients admitted with acute stroke to any of the 28 hospitals nationwide during February through March 2003 and March through April 2007. We compared stroke severity and outcomes of ICH patients who received statins before the index event with those who did not, using multivariable logistic regression models adjusting for the propensity to use statins before the event. Results— Among 3212 stroke patients, 312 had ICH and 89 of them were receiving statins at the time of the ICH. Patients on statins before ICH had lower baseline NIHSS scores, less systemic complications, higher proportions of good outcome (modified Rankin scale 0 to 3), lower death rates, and higher rates of discharge home or to a rehabilitation facility. On logistic regression analyses statin use before the event was associated with odds ratios of 0.46 for having a severe stroke defined as baseline NIHSS >15 (95% CI; 0.23 to 0.93), 2.97 for having good outcome (95% CI; 1.25 to 7.35) at discharge, and 0.25 for death or nursing facility disposition (95% CI; 0.09 to 0.63). Conclusions— Use of statins before ICH is associated with reduced mortality and neurological disability and with a higher chance for good outcome, suggesting that statins may be protective in the setting of ICH.

State-of-the-art reperfusion strategies for acute ischemic stroke

Timely recanalization of the occluded artery is the only effective treatment for acute ischemic stroke. Intravenous tissue plasminogen activator (i.v. tPA), administered within 3 hours of symptom onset, is the only United States Food and Drug Administration-approved treatment. This short window often precludes effective intervention, and i.v. tPA often fails to recanalize major and mid-sized arteries. Intra-arterial thrombolysis has been used for decades, but its safety and effectiveness in cerebrovascular occlusions is also limited. Recently, new mechanical neuroendovascular devices have shown high recanalization rates with acceptable safety in early studies. Multi-modal reperfusion therapy (MMRT)--including intra-arterial infusion of thrombolytics and/or antiplatelet agents, mechanical clot disruption and retrieval, and balloon angioplasty with stent placement--is the prevailing concept for the management of major acute stroke. Recent results suggest that MMRT results in higher chances for both recanalization of the occluded artery and reperfusion of the ischemic tissue.

Prior use of statins and outcome in patients with intracerebral haemorrhage

Background:u2002 Pre‐treatment with cholesterol lowering drugs of the statin family may exert protective effects in patients with ischaemic stroke and subarachnoid haemorrhage but their effects are not clear in patients with intracerebral haemorrhage (ICH).

Multimodal reperfusion therapy in patients with acute basilar artery occlusion.

OBJECTIVEMultimodal reperfusion therapy (MMRT) has been advocated for the treatment of acute basilar artery occlusion (ABAO). We aimed to identify prognostic factors in patients with ABAO who underwent MMRT. METHODSClinical and radiological data from consecutive ABAO patients were analyzed. All patients underwent MMRT on an emergency basis. Stroke subtypes were categorized according to TOAST (Trial of ORG 10172 in Acute Stroke Treatment) criteria. Good outcome was defined as a modified Rankin Scale score of 3 or less and poor outcome as a score of 4 or more at 30 days poststroke. RESULTSTwenty-four patients were included (18 men, 6 women) with a mean age of 54.7 years (age range, 26–70 years). Six patients died (25%), and 8 of the surviving 18 patients (44%) achieved a modified Rankin Scale score of 3 or less at 30 days. We could not identify any clinical or radiological variables that were associated with a greater likelihood of good or poor outcome at 30 days other than the presence of good collateral circulation, which was associated with better outcome on univariate analysis. CONCLUSIONMMRT resulted in high survival and good outcome rates. We could not identify prognostic factors in patients with ABAO treated with MMRT other than the presence of collateral flow. Our results imply that patients should not be excluded from treatment based on clinical or radiological parameters, and that all patients with ABAO should be given the chance to benefit from therapy.

Multi-Modal Reperfusion Therapy for Patients With Acute Anterior Circulation Stroke in Israel

Background and Purpose— We aimed to delineate prognostic variables in Israeli patients with anterior circulation strokes treated with endovascular multi-modal reperfusion therapy (MMRT). Methods— Clinical and radiological data from consecutive tpa-ineligible stroke patients with large anterior circulation infarcts involving either the entire internal carotid artery or the proximal middle cerebral artery territory were analyzed. Stroke subtypes were categorized according to TOAST criteria. Neurological deficits were assessed with the NIH stroke scale (NIHSS), and vessel recanalization was determined using the thrombolysis in myocardial infarction (TIMI) scale at the end of MRRT. Good outcome was defined as a modified Rankin score (mRS) ≤2. Results— Fifty patients were included with a median age of 68. Thirteen patients died and 17 patients achieved an mRS ≤2 at 90 days. Variables associated with survival on multivariate analysis were admission NIHSS <20 (OR 15 95% CI 1 to 230) and postprocedure TIMI score 2 to 3 (OR 35.5 95% CI 2.3 to 603.9). Variables associated with good outcome included admission NIHSS <20 (OR 9.4 95% CI 1.3 to 71.3), day 1 NIHSS <15 (OR 6.4 95% CI 1.1 to 38.4), and postprocedure TIMI 3 (OR 7.4 95% CI 1.1 to 50.3). Conclusions— MMRT resulted in high survival and good outcome rates in these critically ill patients. Lower baseline impairment and vessel recanalization increase the chances for good outcome. Our results suggest that the benefits of MMRT may merit further study and could be generalized to centers outside the United States and Europe.

Prior use of angiotensin-converting enzyme inhibitors does not affect outcome in patients with intracerebral hemorrhage

Abstract Background and objectives: Angiotensin-converting enzyme inhibitors (ACEI) exert protective effects in patients with stroke but their effects remain unknown in patients with intracerebral hemorrhage (ICH). Methods: We recruited consecutive patients with acute ICH and analysed pre-admission demographic variables and drug therapy as well as clinical and radiological parameters. Functional and neurological outcomes were determined with the modified Rankin score (mRS) and the NIH Stroke Scale (NIHSS) score administered 90 days after ICH. Results: Three hundred and ninety-nine patients were included over 6 years with a mortality rate of 47.3%. Before ICH, 130 patients (32.6%) used ACEI. ACEI-treated patients more often had vascular co-morbidities and were more frequently treated with anti-platelets. Admission NIHSS scores were significantly higher in ACEI-treated patients but 90 days NIHSS scores were not. Improvement from baseline NIHSS scores was significantly larger in ACEI-treated patients. Pre-ICH use of ACEI was not associated with lower mortality or better functional outcome on univariate analysis. On multivariable logistic regression analysis, controlling for possible confounding variables, ACEI use was not associated with increased chances for good outcome and failed to show an influence on mortality. Discussion: In conclusion, our study does not support a possible neuroprotective effect for ACEI use prior to the occurrence of ICH.

Sandfly virus seroconversion associated with neurologic presentation

Objective: To describe the clinical presentation and unique neurologic manifestations of sandfly viruses (SFVs) in the Jerusalem area. Methods: We identified all patients with acute seroconversion to SFV at the Hadassah-Hebrew University Medical Centers during the years 2008–2013 and retrospectively collected and analyzed the clinical and imaging data. Results: Nine patients (ranging from 1.5 to 85 years old) were identified. Presentation included acute neurologic disease, mostly with fever, change in consciousness and behavior, seizures, headache, meningitis, limb paresis, or myelitis. Eight patients had clinical signs of meningitis, meningoencephalitis, or encephalitis alone. Four patients had myelitis. MRI identified pathologic symmetrical changes in the basal ganglia, thalami, and other deep structures in 5 patients, and additional myelitis of the spine was noted on imaging in 3 patients. Seven patients had long-term follow-up: 4 completely recovered and 3 had remaining neurologic sequelae, among them 1 with permanent severe brain damage. Conclusion: Neurologic involvement associated with acute SFV infections is considered to be benign. However, in this series, all 9 patients presented with significant neurologic pathology associated with a unique finding of myelitis and symmetrical basal ganglia, thalami, or white matter involvement. Thus, acute SFV infection should be included in the differential diagnosis in febrile onset of neurologic manifestations and neuroradiologic changes.

Decompressive hemicraniectomy improves outcome in patients with failed arterial recanalization after acute carotid artery occlusion

Abstract Background and objectives: Decompressive hemicraniectomy reduces morbidity and mortality in patients with large hemispheric stroke. However, its role in patients that underwent failed endovascular reperfusion remains unknown. Methods: Patients with acute stroke secondary to internal carotid artery occlusion who underwent endovascular multimodal reperfusion therapy were evaluated. Patients with failed revascularization who were referred for decompressive hemicraniectomy were compared with patients with failed reperfusion who did not undergo decompressive hemicraniectomy. Functional outcome was assessed with the modified Rankin Score (mRS) and neurological disability with the NIH Stroke Scale Score (NIHSS) at 90 days from stroke onset. Results: Six decompressive hemicraniectomy-treated patients were included (four females, mean age: 36.7 years, mean NIHSS: 24.5). None of the decompressive hemicraniectomy-treated patients died compared to six of seven patients with failed multi-modal reperfusion therapy that did not undergo decompressive hemicraniectomy. All decompressive hemicraniectomy-treated patients were discharged to a rehabilitation facility whereas the only surviving non-decompressive hemicraniectomy-treated patient was discharged to a nursing facility. Five of the six decompressive hemicraniectomy-treated (84%) and none of the non-decompressive hemicraniectomy-treated patients had an mRS ≤3 at 90 days post-stroke. Discussion: Decompressive hemicraniectomy can significantly improve functional outcome in patients with large carotid artery strokes that failed to recanalize following multi-modal reperfusion therapy. These results imply that decompressive hemicraniectomy should be planned in patients who undergo multi-modal reperfusion therapy for large carotid artery stroke.

Poster 442: Rehabilitation Outcomes of Stroke Patients Treated With Thrombolysis

discussed substantiation of the IHI concept, cortical excitability apperception, efficacy of transcranial magnetic stimulation (TMS) and tDCS on post-stroke hand motor improvement, correlation of IHI with functional MRI findings, neuroplasticity in animal models, and evidence of TMS/tDCS successfully modulating cortical excitability in post-stroke individuals. Conclusions: IHI may play a role in post-stroke rehabilitation. This theory is supported by a study demonstrating bihemispheric neuromodulation via tDCS enhancement of motor training during unilateral motor training and contralateral hand restraint. Neuromodulation of IHI may provide a promising option to optimize stroke rehabilitative management.
