Abstract
IntroductionDetermining the prognosis of ischemic stroke is important for neurologists and patients. The aim is to study the predictors of three months clinical outcome in ischemic stroke patients.Materials and methodsA total of 397 patients were classified according to three months modified Rankin Scale score (mRS score) into two groups, favorable and unfavorable outcome. Favorable outcome was assumed if the score was zero or one, or unchanged if the score was ≥ 1 before the onset of the most recent event.ResultsThe variables associated with unfavorable outcome were old age (P <0.001), presence of cardiac disease (P <0.001), low ejection fraction (P=0.008), low levels of total cholesterol and low-density lipoproteins (P <0.001), large artery atherosclerosis stroke (P <0.001), early confluent (P=0.005), high National Institute of Health stroke scale (NIHSS) score on admission (P <0.001), mRS score before admission (P <0.001), mRS score on discharge (P <0.001). Lacunar stroke was associated with favorable outcome (P <0.001). The regression analysis showed mRS score on discharge (P <0.001) and the presence of cardiac diseases (P=0.077) as independent predictors of unfavorable outcome.ConclusionHigh mRS score on discharge and presence of the cardiac disease independently could predict the unfavorable outcome and mRS score on discharge had a high sensitivity and negative predictive value in predicting the unfavorable outcome.AbbreviationsMRS: score modified Rankin scale score, NIHSS: National Institutes of Health Stroke Scale, MRI: Magnetic resonance imaging, LDL: Low-density lipoprotein, MRA: Magnetic resonance of arteries.
