Simple prediction model for unfavorable outcome in ischemic stroke after intravenous thrombolytic therapy.

OBJECTIVE: We aimed to develop a model to predict unfavorable outcome in patients with acute ischemic stroke treated with intravenous thrombolytic therapy (IVT), based on simple variables present on admission. METHODS: Retrospective analysis of acute ischemic stroke patients treated with IVT in a hospital in Rio de Janeiro. Clinical and radiographic variables were selected for analysis. Multivariate logistic regression was used to develop a predictive model. RESULTS: We analyzed a total of 82 patients. Median National Institutes of Health Stroke Scale (NIHSS) on admission was 9 (3-22), 40.2% presented with a hyperdense artery sign (HAS), 62% had identifiable early parenchymal changes and 61.6% experienced a favorable outcome. An NIHSS score of > 12 on arrival, age > 70 and the presence of HAS were associated with the outcome, even after correction in a logistic regression model. CONCLUSION: An NIHSS > 12 on arrival, presence of HAS and age > 70 years were predictors of unfavorable outcome at three months in patients with acute ischemic stroke treated with IVT.

RESUMO Objetivo Desenvolver um modelo para predizer desfecho desfavorável em pacientes com acidente vascular cerebral isquêmico (AVCi) agudo tratados com terapia trombolítica intravenosa (TTI), baseado em variáveis simples presentes à admissão. Métodos Análise retrospectiva de casos de AVCi tratados com TTI em um hospital no Rio de Janeiro. Variáveis clínicas e radiográficas foram selecionadas para análise. Foi utilizada regressão logística para desenvolver modelo preditivo. Resultados 82 casos foram analisados. A mediana de escore de National Institutes of Health Stroke Scale (NIHSS) na admissão foi 9 (3–22), 40,2% se apresentaram com sinal da artéria hiperdensa (SAH), 62% possuíam alterações parenquimatosas precoces e 61,6% obtiveram um desfecho favorável. NIHSS > 12, idade > 70 e a presença de SAH foram associados com o desfecho, mesmo após correção em modelo de regressão logística. Conclusão NIHSS > 12, a presença de SAH e idade maior que 70 anos foram preditores de desfecho desfavorável em 3 meses em pacientes com AVCi tratados com TTI.

Migraine patients should be cautiously followed for risk factors leading to cardiovascular disease.

Migraine and ischemic strokes are two of the most prevalent diseases worldwide. Besides having a coincident symptomatology, for long researchers have been searching for a possible causal relation between these diseases. Current evidence based on data suggest that patients with aura migraine could have a doubled risk of developing an ischemic stroke, when compared to the rest of the population. At the same time, migraine sufferers apparently have higher incidences of risk factors for cardiovascular events. The aim of this review was not only to dissect some of the more compelling evidence based on data regarding this association, but also to discuss the possible clinical and therapeutic implications.

Migrânea e acidentes vasculares cerebrais isquêmicos (AVCI) são duas das doenças de maior prevalência em todo o mundo. Além de apresentarem alguns sintomas em comum, há muito tempo pesquisadores procuram investigar uma relação causal entre as duas. As informações atuais baseadas em evidência sugerem que pacientes com migrânea com aura podem ter um risco duas vezes maior de desenvolver AVCI, quando comparados com o restante da população. Ao mesmo tempo, aqueles sofrem de migrânea possuem aparentemente maior incidência de fatores de risco para eventos cardiovasculares. O objetivo desta revisão foi não apenas avaliar grande parte das mais importantes e convincentes evidências científicas sobre esta associação, mas também discutir suas possíveis implicações clínicas e terapêuticas.
