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。
Objective: To investigate the correlation between carotid intima - media thickness (IMT) and left ventricular hypertrophy in patients with essential hypertension (EH). Methods: Cardiac and carotid ultrasonography were performed in 60 patients with EH (EH group) and 20 healthy persons (control group). Left ventricular mass index (LVMI), carotid IMT and plaque were measured. Results: Compared with the control group, the carotid artery IMT, LVMI and plaque detection rate in EH group were significantly increased (P <0.05), while those in EH group were higher than those in normal LVMI group (P <0.05) ; LVMI was positively correlated with carotid IMT. Conclusion: The carotid IMT increased in EH patients, which is closely related to left ventricular hypertrophy.
