【摘要】：目的探討原發(fā)性高血壓動(dòng)態(tài)動(dòng)脈硬化指數(shù)與頸動(dòng)脈彈性功能改變的相關(guān)性。方法選擇原發(fā)性高血壓患者104例和對(duì)照組健康成人50例,二維超聲檢測(cè)頸動(dòng)脈內(nèi)-中膜厚度(IMT),應(yīng)用血管回聲跟蹤技術(shù)(ET)檢測(cè)受檢者頸總動(dòng)脈僵硬度、壓力應(yīng)變系數(shù)、順應(yīng)性、增大指數(shù)、單點(diǎn)脈搏傳播速度等彈性功能參數(shù),將原發(fā)性高血壓患者按IMT≥1.0mm者為頸動(dòng)脈硬化組,1.0mm者為無(wú)頸動(dòng)脈硬化組。通過(guò)24h動(dòng)態(tài)血壓監(jiān)測(cè),計(jì)算動(dòng)態(tài)動(dòng)脈硬化指數(shù)(AASI)。分析AASI與頸動(dòng)脈彈性功能參數(shù)的相關(guān)性。結(jié)果原發(fā)性高血壓患者和對(duì)照組動(dòng)態(tài)動(dòng)脈硬化指數(shù)分別為0.56±0.14和0.41±0.12(P0.01);高血壓頸動(dòng)脈硬化組和無(wú)頸動(dòng)脈硬化組動(dòng)態(tài)動(dòng)脈硬化指數(shù)分別為0.59±0.12和0.50±0.11(P0.05);AASI與頸動(dòng)脈僵硬度、壓力應(yīng)變系數(shù)、膨大指數(shù)、單點(diǎn)脈搏傳導(dǎo)速度呈正相關(guān)(r=0.336、0.269、0.274、0.356,均P0.05),與順應(yīng)性呈負(fù)相關(guān)(r=-0.282,P0.01)。與對(duì)照組比較,高血壓組頸動(dòng)脈僵硬度指數(shù)、壓力應(yīng)變系數(shù)、膨大指數(shù)、單點(diǎn)脈搏傳導(dǎo)速度增大,順應(yīng)性降低(P0.05)。結(jié)論動(dòng)態(tài)動(dòng)脈硬化指數(shù)可以反映頸動(dòng)脈硬化及彈性功能改變。原發(fā)性高血壓動(dòng)態(tài)動(dòng)脈硬化指數(shù)與頸動(dòng)脈粥樣硬化關(guān)系密切。
[Abstract]:Objective to investigate the relationship between dynamic arteriosclerosis index and carotid elastic function in patients with essential hypertension. Methods 104 patients with essential hypertension and 50 healthy adults were selected. Carotid intima-media thickness (IMT) was measured by two-dimensional ultrasound, and elastic parameters such as common carotid artery stiffness, pressure strain coefficient, compliance, increase index, pulse velocity at single point were measured by vascular echo tracking technique (ETT). The patients with essential hypertension were divided into carotid atherosclerosis group (IMT 鈮，
