代谢综合征患者静息心率与颈动脉内膜中层厚度的关系

目的探讨代谢综合征（MS）患者静息心率（RHR）与颈动脉内膜-中层厚度（IMT）的关系。方法对96例MS患者进行调查，每位患者均测RHR、血压、空腹血糖（FPG）、总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白胆固醇（HDL-C）、低密度脂蛋白胆固醇（LDL-C），颈动脉超声检测IMT，按RHR频率分RHR1组：RHR〈70次／min，RHR2组：70-80次／min，RHR3组：RHR〉80次／min。结果代谢综合征患者RHR与IMT呈显著正相关（r=0．432P〈0．01）；且RHR与FPG、TG呈正相关（FPGr=0．24，TGr=0．24，P〈0．05）。结论MS患者RHR与IMT有明显相关性。

Relationship between resting heart rate and carotid arterial intima-media thickness in patients with metabolic syndrome

Objective To study the relationship between resting heart rate（RHR） and carotid arterial intima-media thickness （IMT） in Metabolic Syndrome patients. Methods Ninety-six Metabolic Syndrome patients were enrolled. Their RHR, blood pressure, fasting plasma glucose （ FPG ）, total cholesterol （TC）, triglyceride （TG）, high-density lipoprotein cholesterol（HDL-C ）,low-density lipoprotein cholesterol（ LDL-C ）, Carotid arterial IMT were determined. According to the RHR, the Metabolic Syndrome cases were categorized into 3 groups： group RHR1 （〈70 bpm, n=36）, group RHR2（70-80 bpm,n=35）, group RHR3 （〉80 bpm,n=25）. Results Metabolic Syndrome patients RHR was positively correlated with IMT （r=0.47,P〈0.01）,FPG,TG correlated with RHR （FPG：r=0.24,TG：r=0.24,P〈0.05）. Conclusion Metabolic Syndrome patients RHR is significantly correlated with carotid artery IMT.
