[The prevalence and risk factors of carotid atherosclerosis in elderly patients].
To assess the prevalence of extracranial carotid artery atherosclerosis and its relation to principal cardiovascular risk factors in Chinese elderly patients, 100 cases aged from 54 to 94 were investigated with B-mode ultrasonography. Arterial intima-media thickening, plaque, mild stenosis (defined as a plaque that obstructed > 20% of the lumen diameter), and clinically significant stenosis (> 50% in cross-sectional area) were found in 79, 49, 40 and 3 patients, respectively. There was no significant correlation between carotid atherosclerosis and coronary heart disease, cerebral infarction, hypertension, hyperlipidemia or diabetes. In contrast, the prevalence of carotid atherosclerosis was increased with age (P < 0.05), so did the severity. Thus, age is a major risk factor for carotid atherosclerosis in the elderly.
