Megjegyzések:	Background and Aims: The outcome of intravenous thrombolysis using recombinant tissue plasminogen activator (rtPA) is favorable in only 33?35% of acute ischemic stroke (AIS) patients. We tested whether an ex vivo clot-lysis assay performed before thrombolysis might predict therapy outcomes. Methods: Blood samples of 139 consecutive AIS patients, who underwent intravenous thrombolysis, were taken before thrombolysis. Plateletpoor-plasma was clotted using recombinant tissue factor, then lysis was induced with rtPA. Clot formation and lysis was monitored by turbidimetry in real time. In order to test the impact of neutrophil extracellular traps on lysis, assays were also performed in the presence of cell-freeDNA and histone. Stroke severity was determined by NIHSS on admission. Short- and long-term outcomes were defined at 7 days and 3 months post-event according to the change in NIHSS and by the modified Rankin Scale, respectively. Results: The median time to reach 50% lysis (50%CLT) was 47.3 (IQR:35.0-64.0) min in the total cohort, and became significantly prolonged in the presence of DNA and histone. A dose-response relationship was observed between stroke severity and 50%CLT. Patients with favorable short-term outcome had significantly shorter 50%CLT in the presence of DNA and histone as compared to patients with worse outcomes (median:50.6 (IQR:36.8-70.5) min vs. 62.0 (IQR:45.0-74.7) min; p < 0.05). Long-term outcomes and occurrence of post-lysis hemorrhage showed no association with clot-lysis assay results. 742 European Stroke Journal 4(1S) Conclusions: Clot-lysis assay using plasma of AIS patients taken before thrombolysis might be useful to predict short-term outcomes, but showed no association with hemorrhagic complications and long-term outcomes.
