Combined Clinical and Radiological Prognostic Model in Acute Ischemic Stroke

We sought to propose and test the validity of a comprehensive prognostic model in middle cerebral artery-stroke treated with Intravenous thrombolysis. A total of 127 consecutive patients (aged 70 +/- 12 years; 54% males) were included in this retrospective study. Variables included in our prognostic model were: NIHSS on admission (1-3 points), occurrence of hyperdense middle cerebral artery sign and early ischemic signs on baseline CT (1 point each). NIHSS at 24 hours (0-3 points), posttreatment hemorrhage (1 point), and infarct volume (0-4 points). The score range teas 1-13, with higher values suggest unfavorable prognosis. Our prognostic score was correlated with the modified Rankin scale (mRS) at 3 months after stroke [correlation coefficient of 0.62, P = 7 for unfavorable prognosis helped to predict the need for institutionalization and the functional outcome with higher accuracy and predictive values compared with using scores only based on NIHSS.
