原发性高血压患者颈动脉内-中膜厚度与左室肥厚的相关性

目的:探讨原发性高血压(EH)患者颈动脉内-中膜厚度(IMT)与左室肥厚的相关性。方法:对60例EH患者(EH组)和20例健康者(对照组)行心脏及颈动脉超声检查,分别测量左室质量指数(LVMI)、颈动脉IMT及斑块。结果:与对照组相比,EH组颈动脉IMT、LVMI、斑块检出率均明显增高(P<0.05),EH组LVMI增高者的以上指标又均高于LVMI正常者(P<0.05);LVMI与颈动脉IMT呈正相关。结论:EH患者颈动脉IMT增加,与左室肥厚密切相关。

Study of correlation between intima-media thickness in carotid artery and left ventricular hypertrophy in essential hypertensive patients

Objective:To explore the correlation between intima-media thickness(IMT) in carotid artery and left ventricular hypertrophy in essential hypertensive(EH) patients.Method:Carotid and cardiac ultrasonography were performed on 60 patients with EH and 20 control subjects.Left ventricular mass index(LVMI),IMT and plaque were respectively measured.According to the left ventricular mass index,EH patients were divided into LVMI normal group and LVMI increased group.Result:Compared with the control group,the IMT in carotid artery increased and the prevalence of carotid plaque was higher in EH patients and highest in LVMI increased group.Conclusion:IMT in carotid artery can increase in EH patients and IMT is related to left ventricular hypertrophy.Ultrasonography may be considered as sensitive index of vascular disease.
