老年高血压患者静息心率与颈动脉病变的相关性研究

Study on Correlation of Resting Heart Rate and Pathology of Carotid Artery in Senile Patients with Hypertension

目的探讨老年高血压患者静息心率(RHR)与颈动脉病变的关系。方法将102例高血压患者按RHR值分为3组,RHR1组34例(RHR≥80次/min),RHR2组35例(RHR 70～79次/min),RHR3组33例(RHR<70次/min),检测3组患者双侧颈总动脉内径(CAD)和颈动脉内-中膜厚度(IMT)。结果 3组患者CIMT、CAD比较差异均有统计学意义(P均<0.01),随着RHR的增加CIMT逐渐增厚,CAD逐渐增宽(P<0.01);RHR与CIMT呈正相关(r=0.621,P<0.01)。结论 RHR可作为高血压患者动脉硬化程度的一个检测指标。

Objective To investigate the relationship between resting heart rate（RHR）and pathology of carotid artery in senile patients with hypertension. Methods According to the RHR, 102 cases were divided into three groups, RHR1 group （n = 34, RHR ≥ 80 beats/min ）, RHR2 group （ n = 35,70 beats/min 〈 RHR ≤ 80 beats/rain ） and RHR3 group（n = 33, RHR 〈 70 beats/min）, the carotid intima-media thickness （CIMT）and carotid arterial diameter（ CAD ） were measured in the three groups. Results The differences of carotid IMT and CAD were significant among the three groups（P 〈0.01 ）. Carotid IMT and CAD levels increased significantly following the increasing RHR（P 〈0.01 ） ,RI-IR was positively related with CIMT（r =0.621 ,P 〈0.01 ）. Conclusion RHR may be a good index to reflect the degree of arteriosclerosis in senile patients with hypertension.
