老年高血压患者颈动脉超声检测及临床价值

Carotid artery ultrasonographic measurment and clinical value in the elderly patients with hypertension

目的 了解老年高血压患者动脉粥样硬化的状况 ,探讨超声检测颈动脉粥样硬化在高血压患者中临床价值。方法 检测分析 12 0例老年高血压患者颈总动脉 (CCA)内径、内膜中层厚度 (IMT)、斑块发生率并与 4 5例健康老人对照。结果 高血压组较对照组颈动脉内径及内膜中层厚度增加 (P <0 .0 5 ) ;高血压病各级之间颈动脉IMT比较亦有显著性差异 (P <0 .0 5 ) ,随高血压分级增加颈动脉IMT亦逐渐增厚 ;高血压组的斑块发生率明显高于正常对照组 (P <0 .0 1)。结论 动脉IMT增厚是动脉粥样硬化的早期特征 ,血压增高是引起高血压病颈动脉变化的一个重要因素 ,颈动脉超声检测对于防治老年高血压及其并发症具有重要意义。

Objective Objective To study the status of atherosclerosis in elderly patients with hypertension and to evaluate the value of carotid artery ultrasonographic in hypertensive patients.Methods Carotid artery bores, intima-media thickness (IMT) and the plaque were measured in 120 elderly patients with hypertension and then compared with 45 controls.Results The occurrence rates of carotid artery bores, IMT and plaques were higher in the hypertensive patients than those of the controls. There were significant changes in carotid IMT among different degree of hypertension(p<0.05). The higher the degree of hypertension, the thicker the carotid IMT.Conclusion Incrassation of artery IMT is the early character of atherosclerosis. The increasing of the blood pressure is one of the important reasons to cause the carotid IMT changes in patients with hypertension. Carotid ultrasonography has important meaning for prevention and treatment of hypertension and its cerebrovasculas complications.
