ABSTRACT

Background: differentiating hemorrhagic from ischemic cerebral vascular disease (CVD) is the starting point for the treatment. The aim was to compare the diagnostic accuracy of the scales that differentiate hemorrhagic from ischemic stroke.
Methods: we applied the scale of Siriraj Stroke Score (SSS) and Greek Stroke Score (GSS) to patients with stroke. The results were described as means and frequencies. For significant variables odds ratio was calculated. We calculated the validity of both scales compared to the head computed tomography.
Results: ninety one patients had ischemic stroke and 28 were hemorrhagic. The mean systolic blood pressure in ischemic stroke was 138.94 mmHg (SD ± 26.90) and hemorrhagic was 165.55 mmHg (SD ± 36.40) p = 0.0007. The atherogenic index (AT) in ischemic stroke was 4.52 (SD ± 1.52) and in hemorrhagic was 4.84 (SD ± 2.01) p = 0.87. The specificity of the SSS for hemorrhagic stroke is 85.5 % and 96.7 % for the GSS.
Conclusions: the GSS has a high specificity for hemorrhagic stroke.
