Cardiovascular diseases originating from atherosclerosis appear to be a big problem in the whole world. Type 2 diabetic patients have their specific features of atherosclerosis development. The authors tried to follow up the patients with Type 2 diabetes mellitus and those without it. The average period of the study was 55,1 23,2 months. Mortality in both groups proved to be comparable (p>0,05). In the long-term period, Type 2 diabetic patients underwent coronary revascularization (p = 0,01) and surgery for bilateral carotid arteries (p = 0,005) more often than the patients from the second group.
