Abstract: The measurements for predicting early deterioration of stroke patients is controversial. We studied laboratory measurements and previously identified risk factors to identify factors or predictors of early deterioration after stroke. A prospective observational study of 196 patients with first-time acute ischemic stroke was performed. Demographic data, patient histories, laboratory measurements, and initial stroke severity assessments were recorded. Patients with early deterioration in National Institutes of Health Stroke Scale scores (increase ≥3 points within 3 days) were defined as having stroke-in-evolution (SIE). Thirty patients were diagnosed with SIE. An initial National Institutes of Health Stroke Scale score of 12 or higher, a Glasgow Coma Scale score of 12 or lower, d-dimers more than 1000, or blood urea nitrogen/creatinine (BUN/Cr) ratio higher than 15 were more frequent in SIE patients. After multivariate analysis, only a BUN/Cr higher than 15 was independent predictor of SIE. These patients were 3.41-fold more likely to have SIE (P = .008). These findings suggest that BUN/Cr may be a novel predictor of SIE, potentially useful in emergency departments. [Copyright &y& Elsevier] |
