BEIGELMAN, Ricardo et al. Is Hypertension a Cause of Carotid Dolicoarteriopathies?: A Study with Color Doppler Echocardiography. Rev. argent. cardiol. [online]. 2007, vol.75, n.6, pp.436-442. ISSN 1850-3748.

Background Rol of arterial hypertension (AHT) as a cause of carotid dolicoarteriopathies (CD) is still uncertain. We have previously informed that CD would have an embryological origin as its prevalence is similar in a group of children and adolescents (healthy volunteers) compared with a group of adults. Objectives To determine the relationship between AHT and other cardiovascular risk factors with CD type 2 (loop) and 3 (kinking). Material and methods Observational, descriptive, prospective, transversal and controlled study. Eight hundred and eighty five patients, both sexes, were included, with ages ranging from newborn (aged 4 h 30 min) to 90 years. Patients were divided into two groups: G1 (control group, healthy volunteers), n = 245: new-born, children and adolescents up to 15 years old, and G2: n = 640, patients aged 16 to 90 years referred for a carotid echo-Doppler examination. A history of hypertension, dyslipemia, diabetes mellitus, and smoking was assessed, as well as the presence of atheromatous plaques in the area corresponding to dolicoarteriopathies. Results G1: prevalence of kinking 27% (n=67) and of loop 4% (n=10). G2: kinking 22% (n=143) and loop 3% (n=19) (p=ns between both groups). Risk factors in G2: CD carriers compared with CD non-carriers: AHT (12% vs 11%), smoking (9% vs 10%), dyslipemia (5% vs 4%), diabetes mellitus (1.5% vs 2%); all p values = ns. Atheromatous plaques intrakinking in G2: 4.3%. Conclusions Neither AHT nor other cardiovascular risk factors analyzed or atheromatous plaques are responsible for carotid dolicoarteriopathies.
