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 intracerebral 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.
