Abstract

To evaluate the effect of age and other risk factors for atherosclerosis on arterial blood velocity, carotid arteries in 179 healthy individuals ranging from 21 to 102 years old were examined using color Doppler ultrasonography. Velocity in common and internal carotid arteries decreased consecutively from young adults to very elderly people except for peak internal carotid artery velocity. Peak common carotid artery velocity in the elderly (ĝ‰¥ 65 years old) people was inversely associated with age and diastolic blood pressure and directly associated with pulse pressure. Minimum velocity of common carotid artery was inversely correlated with age and diastolic blood pressure in the elderly people. In elderly group, peak internal carotid artery velocity correlated only with serum high-density lipoprotein cholesterol. Minimum internal carotid artery velocity correlated inversely with systolic blood pressure in adults and diastolic blood pressure in elderly people. Blood velocity in the very elderly population approaches the critical level for thrombogenesis.
