心血管危险因素对颈动脉粥样硬化的影响及超声评价的意义

Carotid Artery Atherosclerosis as a Cardiovascular Risk Factor and Its Significance by Carotid Ultrasound Evaluation

越来越多的研究表明心血管危险因素导致了颈动脉内膜中层厚度(IMT)增厚;超声检测到的颈动脉粥样硬化与冠脉造影所示的冠状动脉粥样硬化严重程度明显相关。目前颈动脉IMT可作为反映动脉粥样硬化的指标。由于颈动脉超声检查无创、准确、简便、重复性好,可用于对新发现的或已确定的危险因素进行综合评价,也可用于通过临床对高危因素干预后,动态观察动脉粥样硬化的进展及消退,还对冠心病高危人群发生心血管事件的预测具有重要意义。

Recent evidence suggests that cardiovascular risk factor contributes to carotid artery intima-media thickness （ IMT）, and suggest a clear link between the degree of carotid artery atherosclerosis detected by ultrasound, and the extent of coronary artery atherosclerosis identified by coronary arteriography. At present, carotid artery IMT is viewed as an index for assessment of artery atherosclerosis. Carotid artery ultrasonic examination is a safe, noninvasive and repeatable method of detecting artery atherosclerosis. It is useful in evaluating newly discovered or definitive risk factors in general, and also in observing the progression or depression of atheroselerosis following clinical intervention and therapy, in particular become a marker for prediction of cardiovascular events in people with cardiovascular risks.
