目的:探讨老老年患者颈动脉中层厚度(IMT)及其相关危险因素的关系,为老老年患者心脑血管疾病的预防及治疗提供临床参考。方法:根据年龄将139例老老年患者纳入分析,有血糖、血压、血脂代谢紊乱的123例作为观察组,无血糖、血压、血脂代谢紊乱的16例作为对照组,分别进行颈动脉超声检查、动态血压监测、糖化血红蛋白及血脂等生化指标检查,并结合临床资料进行分析。结果: 老老年患者均无一例外地存在着IMT增厚,在相同的年龄情况下,吸烟史、血脂紊乱、糖调节异常、血管炎症反应与IMT的增厚呈正相关,各组未显示出统计学差异,IMT的发生发展与年龄、性别、吸烟史、血糖、血压控制水平及血脂紊乱等因素在两组对照中均未显示出统计学差异,多因素Logistic回归分析,显示年龄、吸烟史及病程为危险因素(OR为0500～1196)。结论:老老年患者均不同程度地存在着IMT增厚,其中增龄是其最主要的危险因素,但是对合并有血糖、血压、血脂代谢紊乱的老老年患者也应该积极重视对各种危险因素的筛选和干预,特别在疾病发生发展的早期可能对延缓病变的进展和减少心脑血管事件有一定意义,可是其用药的安全性在该类患者就显得尤为重要。
【摘要】 目的 研究合并2型糖尿病的冠心病患者冠状动脉病变程度与血清视黄醇结合蛋白4（retinol-binding protein 4，RBP4）水平的相关性。 方法 2008年10月-2010年4月选择性冠状动脉造影确诊的冠心病患者共120例，分为单纯冠心病组（A组）60例和冠心病合并糖尿病组（B组）60例，检测血糖、血脂、胰岛素以及脂联素、RBP4水平；根据冠状动脉造影结果，以Gensini评分评判冠状动脉病变程度。 结果 B组空腹血糖、胰岛素、RBP4均显著高于A组（Plt;0.05）；冠状动脉病变程度更重（Plt;0.05）。相关性分析显示RBP4水平与低密度脂蛋白胆固醇、胰岛素抵抗和冠状动脉病变积分呈正相关（r=0.312、0.322、0.314，Plt;0.05）。与脂联素水平呈负相关（r=-0.362，Plt;0.01）。 结论 冠心病合并2型糖尿病患者RBP4明显升高，且与冠状动脉狭窄程度呈正相关。【Abstract】 Objective To explore the relationship between the level of serum retinol-binding protein 4 (RBP4) and the extent of coronary lesions in coronary heart disease (CHD) patients accompanied with type 2 diabetes mellitus (T2DM). Methods A total of 120 patients with CHD diagnosed by coronary arteriongraphy between October 2008 and April 2010 were enrolled. The patients were divided into two groups: CHD group (60 patients); CHD accompanied with T2DM group (60 patients). The levels of serum insulin, adiponectin and RBP4 were measured. All the patients underwent coronary angiography and the extent of coronary lesions was assessed quantitatively based on the Gensini′s scoring system. Results The levels of serum insulin, plasma RBP4 and the extent of coronary artery stenosis in CHD accompanied with T2DM group were significantly higher than those in CHD group (Plt;0.05). Correlation analysis showed that the level of RBP4 was positively correlated with LDL-C, insulin resistance index and the coronary artery narrow degree（r=0.312, 0.322, 0.314; Plt;0.05); and negatively correlated with adiponectin (r=-0.362, Plt;0.01). Conclusion The significant elevated plasma RBP4 in CHD patients accompanied with T2DM is positively correlated with the extent of coronary artery lesion.
