With the results obtained from study realized on 90 "normal" elderly subjects and 686 elderly patients with hypertension and/or diabetes showed that: There is no difference on intima-media thickness (IMT) of carotid artery and its bifurcation between right site and left site. The average IMT at common carotid artery and its bifurcation between is sinificantly higher in elderly patients with hypertension and/or diabetes than in "normal" elderly subjects. The rate of thickness of carotid IMT and its birfucation in the elderly with hypertension and/or diabetes is significantly higher than "normal" elderly subjects. This rate has no difference between age-groups but significantly higher in men.
