Intravenous recombinant tissue plasminogen activator for acute stroke in Poland: an analysis based on the Safe Implementation of Thrombolysis in Stroke (SITS) Registry.

OBJECTIVES

Intravenous thrombolysis was conditionally approved in the European Union (EU) in 2002, under the requirement of entering all patients into Safe Implementation of Thrombolysis in Stroke - Monitoring Study (SITS-MOST). Countries not belonging to the EU by 2002, i.e. Poland were invited to enter data into the SITS International Stroke Thrombolysis Registry (SITS-ISTR). The aim of this study is to compare the safety and efficacy of thrombolysis in the Polish SITS-ISTR stroke patient population with patients registered in SITS-MOST.

METHODS

481 patients in Poland were reported between 2003 and 2007. Baseline and outcome data of Polish patients were compared with SITS-MOST.

RESULTS

Most of the baseline characteristics did not differ between the groups. The most important was the onset-to-needle and door-to-needle times were significantly longer in Polish patients, 150 vs 136 min and 82 vs 68 min, respectively (P < 0.001). The symptomatic intracranial haemorrhage and independence rates at 3 months were similar in both populations. Polish patients had a significantly higher 3-month mortality rate, 18.6% vs 11.3% (P < 0.001).

CONCLUSIONS

Because of higher mortality the study implies the need to improve the organization of thrombolysis services and provides the rationale to continue the monitoring of treatment in Poland.
