Epidemiology of hemorrhagic stroke in the Coast and Gorski Kotar County - Croatia during the period 2001-2005: a hospital based study

Background: The aim of the study was to examine the frequency of hemorrhagic stroke in the Coast and Gorski Kotar County - Western Croatian region. Methods: Most of these patients had been treated at the Department of Neurology, Rijeka University Hospital Center. Using medical records and protocols the epidemiological characteristics of hemorrhagic strokes (HS) were analyzed for five-year period (2001-2005). Average annual age and sex incidence rates per 100 000 population were calculated. Brain hemorrhages were grouped according to age, gender, location, volume of hematomas. Glasgow Comma Score (GCS), risk factors and treatment outcome were analyzed. Results: During the five-years period there were in total 3699 stroke patients out of which 590 (15.9%) had had HS. Four hundred and forty five of them were residents of Coast and Gorski Kotar County (239 men and 206 women). The age-adjusted incidence rate was 28.22/100 000 (CI 95% 22.54-34.91), for males 30.57 (CI 95% 22.28-40.90), for female 26.02 (CI 95% 18.58-35.44). The mean age for men was 68+/-11.2, women 67+/-10.8. The most common localization of hemorrhages were basal ganglia and thalamus 200 (44.9%). Seventhy patients (15.7%) had had subarachnoidal hemorrhages. Hypertension was the most common risk factor followed by hyperlipidemy and obesity. More than half of patients had more than one risk factor. Discussion: In this study we have examined preliminary epidemiological and clinical data of brain hemorrhages, which, as a separate group, were not proper followed up in this region of Coast and Gorski Kotar County. Further prospective studies have been predicted.
