Abstract

Background and purpose: Epidemiological rates for stroke obtained in the United States and Western Europe indicate a decrease in incidence and case fatality. Data published for Poland, as for other Central-Eastern European countries, reported unfavourable results, but this was based on data from the 1990s. The authors evaluated current stroke rates in a population study of the southern Poland city of Zabrze.

Material and methods: A retrospective registry of all stroke cases treated in Zabrze, southern Poland, in 2005-2006, was established, based on data from the National Health Fund. Cases were identified by verifying patient files. Epidemiological rates were calculated and standardized to the European population in both groups: all stroke patients, including recurrent (all strokes, AS), and patients with first-ever stroke (FES) in their history.

Results: We registered 731 strokes, including 572 FES cases (78.3%) and 159 recurrent strokes (21.7%). There were 385 strokes in men (52.7%), and 346 in women (47.2%); 88.6% were ischaemic strokes (IS), and 11.4% were intra-ce-rebral haemorrhages (ICH). The standardized incidence rate for AS patients was 167/100 000 (211 for men, 130 for women), and in the FES group 131/100 000 (161 for men, 104 for women). Twenty-eight day case fatality for the AS group was 18.3% (15.4% for IS, 41% for ICH), and 16.6% for FES (13.4% for IS, 40.9% for ICH).

Conclusions: Incidence rates in this southern Poland city are comparable to those reported previously for Poland. Early case fatality decreased, compared to previous data, probably as a result of improved management of acute stroke and hospitalizing all stroke patients.
