Objectives:
To identify the clinical factors which predicted the outcome of ischemic stroke patients in northwest China.
Patients And Methods:
We retrospectively reviewed 489 consecutive patients with ischemic stroke admitted to the Neurology Department of Xijing Hospital. Demographic, clinical and laboratory data were recorded. Follow-up assessments were performed by telephone interviews or letters. The clinical outcome was assessed by using the modified Rankin Scale (mRS) and categorized as good (score 0-2) or poor (score 3-6) outcomes. Univariate and multivariate logistic regression analyses were performed to explore predictors of ischemic stroke.
Results:
The follow-up period was up to 47 months (mean, 28.3 months). Fifty-five patients (11.2%) were lost. Among these 434 patients, 244 (56.2%) patients had good outcome and 190 (43.8%) had poor outcome. The poor outcome was associated with old age (OR: 3.505; CI 95%: 2.100-5.849), lower educational level (OR: 0.686; CI 95%: 0.570-0.825), having stroke history (OR: 2.481; CI 95%: 1.442-4.268), and higher NIHSS total score (OR: 2.619; CI 95%: 1.584-4.330).
Conclusion:
The results suggest that age, the educational level, stroke history, and NIHSS score are useful in the prediction of functional outcome of ischemic stroke in Chinese northwest area.
