Predictors of Long-term Outcome after Intravenous or Intra-arterial Recombinant Tissue Plasminogen Activator Treatment in the Eastern Hungarian Thrombolysis Database.

BACKGROUND: This prospective single-center study aimed to identify features determining long-term outcome after thrombolysis in a Central European stroke population. METHODS: Between 1 January, 2004, and 31 December, 2010, 415 patients were treated with recombinant tissue plasminogen activator at the Department of Neurology, University of Debrecen. Stroke severity by the National Institute of Health Stroke Scale score (NIHSSS) and imaging findings by the Alberta Stroke Programme Early Computed Tomography score (ASPECTS) were evaluated on admission and 1 day later. The modified Rankin Scale (mRS) at 3 months and case fatality at 1 year were evaluated. Independent predictors of outcome were identified by multivariate testing. RESULTS: Data of 369 patients were analyzed. Median NIHSSS was 12 (interquartile range [IQR], 8-17) on admission and 10 (IQR, 5-16) at 24 hours. Arterial occlusion was found in 55%. Symptomatic intracerebral hemorrhage (SICH) was detected in 3.8%. Outcome was significantly worse, and SICH was more frequent in intra-arterially treated patients. At 3 months, one third of the patients were independent (mRS
