Sažetak
Radi utvrđivanja povezanosti razine lipida u serumu, arterijske hipertenzije, pušenja i dijabetesa sa stupnjem aterosklerotskih promjena karotidnih arterija, 56 muškaraca (srednja dob = 62,9 godina, S.D = 9,4) podvrgnuto je ultrazvučnom pregledu karotidnih arterija. Prema ultrazvučnom nalazu (kriteriji obojenog doplera), bolesnici su bili podijeljeni u dvije skupine (prva – uredan nalaz ili suženje lumena arterije <50%; druga – suženje ≥50% ili ulceracija aterosklerotičkog plaka). Prvu skupinu činilo je 36 (64,3%), a drugu 20 (35,7%) bolesnika. Srednje vrijednosti ukupnog kolesterola, LDL i HDL-kolesterola te triglicerida u serumu nisu se značajno razlikovale između bolesnika u prvoj i drugoj skupini i bile su u granicama normale. Nije bilo ni značajne razlike između obje skupine u zastupljenosti dijabetesa, pušenja ili arterijske hipertenzije. Primjenom logističke regresijske postupne analize dokazano je da jedino životna dob signifikantno povećava rizik od značajne karotidne arteroskleroze (s relativnom šansom od 2,0, 95% CI:1-4.3). Ovakvi rezultati upućuju na važnost životne dobi u patogenezi ateroskleroze.
Summary

Summary. In order to identify association between serum lipid levels, hypertension, smoking, diabetes and the severity of carotid atherosclerosis, ultrasonography of extracranial arteries was performed in 56 male patients (age: –=62.9 years, S.D.=9.4) with transient ischaemic attack. According to color doppler criteria, patients were divided into two groups – Group I: <50%, Group II: ≥50% stenosis of the carotid artery. In Group I, there were 36 (64.3%), and in Group II 20 (35.7%) patients. No significant differences between those two groups were found regarding mean levels of total cholesterol, LDL- and HDL-choles- terol, and triglycerides (normolipemic levels were found in both groups). Two groups were compared also concerning the incidence of hypertension, diabetes and smoking, and no significant difference was found, as well. Stepwise multiple logistic regression analysis revealed that only age significantly increased the risk of severe carotid atherosclerosis (odds ratio 2.0, 95% CI:1-4.3). These results show the influence of age in pathogenesis of carotid atherosclerosis.
