Application of video electroencephalogram in evaluation of short-term prognosis in patients with acute ischemic stroke

  Objective  To explore the value of video electroencephalography(VEEG) in evaluation of clinical prognosis of the patients with acute ischemic stroke(AIS).

  Methods  A total of 85 patients with AIS treated in our hospital were selected as objects. All patients were performed VEEG examination at 24 h of admission, and the clinical data were collected. The clinical prognosis condition after 3 months were evaluated by modified Rankin scale(mRS).

  Results  The poor prognosis group had higher results in the National Institutes of Health Stroke Scale(NIHSS) score, brain symmetry index(BSI), wave ratio of(δ+θ)to(α+β)(DTABR) than good prognosis group, while proportion of gradeⅠand Ⅱ by VEEG grading were lower than that in good prognosis group(P < 0.05 or P < 0.01). BSI, DTABR, VEEG grading were positively correlated with NIHSS score and mRS score, and NIHSS score was also positively correlated with mRS score. ROC curve analysis showed that the sensitivities of BSI and DTABR in evaluating prognosis were higher than that of NIHSS score(P < 0.05). BSI and DTABR were independent influencing factors for the prognosis of stroke. The higher value of BSI and DTABR was, the higher the risk of poor prognosis would be.

  Conclusion  Quantitative indicators such as VEEG BSI and DTABR could effectively assess the prognosis of patients, and may be as independent prognostic indicators.
