Poland is a country with high morbidity and mortality rates from cardiovascular diseases. No recent studies have evaluated the contribution of cerebrovascular diseases to this morbidity and mortality. Our aim was to accurately determine stroke incidence rates in Warsaw, Poland.
A 2-year prospective and population-based stroke registry was maintained for health care units 2 and 3 in Warsaw, Poland (population, 182,285). Case subjects were ascertained by surveying hospital admissions, outpatient visits, and death certificates.
During the 2 years of the study (1991 to 1992), 633 cases of first-event strokes were registered, 462 of which were first ever in a lifetime. Computed tomography or necropsy was performed in 72% of first-ever stroke cases. The crude annual incidence rate for first-ever stroke was 127/100,000 (95% confidence intervals, 111 to 145); the rate standardized to the European population was 111 (95% confidence intervals, 96 to 128). Our incidence rates for first-event strokes were found to be in the middle of the range among other first-event studies. When comparing our first-ever stroke incidence rates with those of comparable studies performed throughout Europe, they were found to be similar for groups aged younger than 65 years but lower in the older age groups. The distribution of ischemic and hemorrhagic stroke subtypes was similar to that of other countries.
This first population-based prospective stroke registry in Poland showed that incidence rates were not high compared with other studies throughout Europe and the world. These stroke incidence rates are not a large contributing factor to high cardiovascular morbidity rates in Poland.
Background: We recently discovered that APOE ε3/ε4 genotype in men and APOE ε2/ε3 genotype in women are associated with increased risk of death from ischemic stroke (IS). One of the main physiological roles of apolipoprotein E is participation in cholesterol metabolism. A significant association of low serum cholesterol level with increased risk of death from stroke was documented. So, we aimed to establish if an association exists between APOE genotype, serum cholesterol and 1-month mortality in IS. Methods: We studied 666 patients (330 men, 336 women) with a diagnosis of IS. Total serum cholesterol (TC) was measured with the method of Abbott Spectrum (USA). APOE genotyping was performed by PCR-RFLP method. Results:The highest frequency of low serum TC was associated with APOE ε2/ε3 genotype (both in men and in women). Low serum TC was associated with increased mortality rate only in women; this effect was evident only in females not possessing APOE ε2/ε3. Female patients with APOE ε2/ε3 genotype had high 1-month mortality rate independently from serum TC. In multiple regression analyses APOE ε3/ε4 genotype in men and APOE ε2/ε3 genotype in women predicted risk of death independently from serum TC and also from other potential pre- and post-stroke prognostic factors. Conclusion:APOE ε3/ε4 genotype in men and APOE ε2/ε3 in women are associated with increased 30-day mortality in stroke. This effect seems be independent from serum cholesterol.
The present study was undertaken to assess the diagnostic value of CT in patients with poststroke epilepsy, related to EEG in revealing the factors contributing to the development of epileptic fits. The EEG and CT results were evaluated in 50 patients with poststroke epilepsy and compared with those of 50 patients without epilepsy after stroke. Cortical and extensive lesions involving the cortex were more frequent among patients with poststroke epilepsy. Sparing of certain parts of cerebral cortex was observed within vasogenic lesion. This type of change was only found in the poststroke epilepsy group and may be responsible for development of epileptic fits. It seems that CT has a higher diagnostic value than EEG in evaluating the risk of development of poststroke epilepsy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
