FREQUENCY OF DIFFERENT RISK FACTORS FOR ISCHEMIC STROKE

In order to assess the incidence of different stroke subtypes we investigated 549 patients with nonfatal stroke out of 870 patients with ischemic stroke hospitalised at Neurology Department University Hospital "Sestre milosrdnice" during one year period. 311 patients were not included in the analysis due to insufficient data for the classification of the stroke subtypes. According to etiology, patients were classified into four groups: large artery disease, cardioembolism, small vessel disease and unknown or known but undetermined origin. Patients underwent clinical and neurological investigation. Electrocardiography, Color Doppler Sonography of carotid arteries, Computerised tomography of the brain and blood laboratory tests were done. The highest incidence of stroke was between 55-64 and 65-74 years in males, and between 65-74 and 75-84 in females. Small vessel disease was the leading cause in both sexes (36%). In males, second cause was the large artery disease (32%), and the third cardioembolism (24%). In males, large artery disease was the most frequent cause of stroke in age groups 45-64. In female's cardioembolism was the second leading cause (34%), and large artery disease the third (17%). Stroke is more frequent in males, and in younger age groups. Small vessel disease is the most frequent cause of nonfatal stroke in both sexes and large artery disease in younger males.
