目的探讨中国老年人群踝臂指数(ABI)与无症状性颈动脉粥样硬化的关系。方法采用横断面研究方法,在参加“青岛港健康研究”的人群中,挑选年龄大于55岁,既往无冠心病、脑卒中和周围动脉病史共507人,进行颈动脉超声和四肢血压的检查。结果颈动脉粥样硬化的患者踝臂指数明显减低,多因素回归分析进一步说明踝臂指数减低与颈动脉粥样硬化独立相关。结论踝臂指数与颈动脉粥样硬化密切相关,是其独立的危险因素。
Objective To investigate the relationship between ankle brachial index (ABI) and asymptomatic carotid atherosclerosis in Chinese elderly population. Methods A cross-sectional study was conducted to select carotid artery ultrasound and limbs blood pressure in 507 people aged 55 or older who had no history of coronary heart disease, stroke and peripheral arterial disease during the “Qingdao Port Health Research”. Results The ankle-brachial index of patients with carotid atherosclerosis was significantly decreased. Multivariate regression analysis further demonstrated that the reduction of ankle-brachial index was independently associated with carotid atherosclerosis. Conclusion Ankle-brachial index is closely related to carotid atherosclerosis and is an independent risk factor.
