Aim: The aim is to determine the frequency of stroke in 300 patients with type 1 and 2 diabetes mellitus observed in two different time periods with a five-year distance. Materials and Methods: The survey comprised a group of 300 patients with previously clinically and laboratory diagnosed diabetes. First examination, questionnaire and laboratory testing were performed in all patients in 1999. There were 62 patients with type 1 diabetes and 238 type 2. The final exam, questionnaire and laboratory test were performed on 278 patients in 2004 (diabetes type 1 in 58 (20.9%), diabetes type 2 in 220 (79.1%) patients. Additional anamnesis in 2004 grouped 2 patients into other specific types, and those were two women, previously classified as diabetes type 2. Twenty patients died between the first test in 2000 and the last in 2004. Results: In 1999 2.2 % of tested patients suffered the stroke , and in 2004, the stroke suffered 3.2%. There was no statistically significant difference in the stroke occurrence in the same group of diabetic patients during the two observed periods with the 5-year time span. There was no statistically significant difference in the occurrence of stroke between males and females, or in type I and II diabetes groups. There were 4.3 % of patients in total who suffered stroke during the survey. Conclusion: There were no statistically significant changes in number of stroke patients which indirectly confirms good treatment of diabetic population in primary care.
