Carotid artery plaque in patients with disorders of glucose regulation]

The aim of this study was measurement of artery intima media thickness (IMT) and plaques as an early indicator of atherosclerosis in diabetics comparing with other risk factors of carotid artery.110 pts: 50 with Diabetes Mellitus, type 1 (25) and type 2 (25), 20 pts with glucose intolerance, 20 pts with type 2 de novo and 20 pts obese without diabetes. Ultrasound examination (using 7.5 MHz sound on Toshiba SSA-270A) end measurement of intima-media ticknes (IMT) were performed on Carotis communis (CCA), bifurcation and distal from bifurcation to a.carotis intern (ACI), expressed in mm. Plaques were correlated with other common factors age, BP, lipid parameters (Chol, HDL, LDL, Triglycerides), smoks, alcoholism and obese (BMI). The authors used 2 test and Spearman's correlation.The lowest percent of plaques was found in group with type DM 1. The highest percent of plaques was found in type DM 2. Statistically there is highly significant difference between plaques founded on type 2 DM and types 2 DM de novo and on other types.DM is not an independent risk factor for developing of macroangiopathic changes an arterial walls, but their appirience are more presenting in diabetic patients. The highest number of plaques are presenting DM type 2 (29.6%), and after type 2 de novo (26.8%), the next highest position of plaques were in patients with obese but without DM and intolerantio glucosae (IFG+IGT) (17.1%) and type 1 DM (9.8%). Risk factors were presented in following percentage: Obese 80.5% pts; hyperlipidema 53.7% pts; HTA 51.3%; smoking 51.2% pts and alchocholism 2.4% pts. According to these results, all risk factors were included in patophysiology of plack forming except alcoholism. Influences of these risk faktors are very importance and their synergic action lids to their rapid appirience and clinical manifestations. DM has specific position in patophisiology of atherosclerosis.
