摘　　要：目的应用E-Tracking技术探讨高血压合并心房颤动患者颈动脉管壁弹性功能。方法对36例原发性高血压患者(高血压组)、37例高血压合并心房颤动患者(高血压合并房颤组)及35名健康志愿者(正常对照组),应用血管回声跟踪技术记录颈动脉管壁的硬度指数(β)、弹性系数(Eρ)、顺应性(AC),同时测量颈动脉内-中膜厚度(IMT)及内径(D)。结果与正常对照组比较,高血压组及高血压合并房颤组β、Eρ、IMT、D均增加,AC减低;与高血压组比较,高血压合并心房颤动组β、Eρ、IMT均增加,AC减低,差异均有统计学意义(P均<0.05)。当IMT≤1.0mm且管径无增宽时,各组β、Eρ比较结果同上。年龄、体质量指数、低密度脂蛋白是高血压合并心房颤动IMT的危险因素。结论高血压合并心房颤动者颈动脉IMT增厚,弹性功能减低;年龄、体质量指数、低密度脂蛋白是其危险因素。颈动脉无明显形态学改变时,颈动脉弹性功能已减低;血管回声跟踪技术能早期检测动脉粥样硬化。Objective To assess carotid elasticity in patients with essential hypertension and arterial fibrillation using E-tracking technique. Methods Thirty-six patients with essential hypertension （EH group）, 37 with hypertension and atrial fibrillation （hypertension with atrial fibrillation group） and 35 healthy volunteers （control group） were selected. Carotid artery stiffness parameters （β）, modulus of elasticity （Eρ）, compliance （AC）, carotid artery intima-media thickness （IMT） and diameter （D） were measured and recorded by using E-tracking technique. Results Compared with control group, β, Eρ, IMT and D in hypertension group and hypertension with atrial fibrillation group increased, AC decreased. Compared with the hypertension group, β, Eρ and IMT in atrial fibrillation with hypertension group increased, AC decreased （all P〈0.05）. When IMT≤1.0 mm without vasodilation, β and Eρ among three groups showed the same trends as the above mentioned. Multiple linear regression analysis showed that age, body mass index and low density lipoprotein were the risk factors for patients with hypertension and atrial fibrillation. Conclusion Carotid IMT of patients with hypertension and atrial fibrillation increases, elasticity decreases. Age, BMI and low density lipoprotein cholesterol are the risk factors for patients with hypertension and atrial fibrillation. E-tracking technique can early detect modification of carotid artery elasticity before the onset of obvious morphological changes.
