ABSTRACT

ABSTRACT 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.
