[Comparative study of stroke morbidity in Tartu (Estonian SSR) and in Espoo and Kauniainen (Finland)].

The incidence of strokes was studied in Tartu (Estonian SSR) during 1970-1973 and in Espoo-Kauniainen (Finland) during 1972-1973. The study involves only cases of first strokes. According to the standardized data (the population of Finland for 1970 was accepted as a standard) the incidence for strokes in Tartu was 160 cases per year. The incidence in Espoo-Kauniainen was higher mainly among females younger than 50 years due to more frequent subarachnoidal hemorrhages in Finland. In both cities the incidence was somewhat higher in males, rather than in females. Lethality during the first 3 months was higher in Tartu (51%), than in Espoo-Kaunianen (39%) due to an older population.
