目的探讨老年原发性高血压病患者颈动脉内-中膜厚度与左室肥厚的相关性。方法选取80例老年原发性高血压病患者(EH组)和32例正常人(对照组),应用二维超声检查心脏及颈动脉,分别测量左室质量指数(LVMI)、颈总动脉内膜-中层厚度(IMT)及斑块情况,并进行分析、比较。结果与对照组相比,EH组LVMI、IMT、斑块检出率均明显增高,EH组LVMI增高者以上指标又均高于LVMI正常者。两组的LVMI与IMT呈显著正相关(r=0.79,p<0.01)。结论老年原发性高血压病患者颈动脉IMT增加,与左室肥厚密切相关。
Objective To investigate the relationship between carotid intima - media thickness and left ventricular hypertrophy in elderly patients with essential hypertension. Methods 80 elderly patients with essential hypertension (EH group) and 32 healthy controls (control group) were selected. Cardiac and carotid arteries were examined by two-dimensional echocardiography. Left ventricular mass index (LVMI), common carotid artery Membrane - middle thickness (IMT) and plaque conditions, and analysis, comparison. Results Compared with the control group, the detection rates of LVMI, IMT and plaque in EH group were significantly higher than those in control group, while those in EH group were higher than those with LVMI. There was a significant positive correlation between LVMI and IMT (r = 0.79, p <0.01). Conclusion The carotid artery IMT in elderly patients with essential hypertension is closely related to left ventricular hypertrophy.
