摘要 目的探讨冠状动脉粥样硬化性心脏病(CHD)患者大动脉顺应性及颈动脉内-中膜厚度(IMT)的变化。方法根据冠状动脉造影结果将128例患者分为冠心病组(76例)和非冠心病组(62例)。利用无创脉搏波速(PWV)测定仪对所有入选者测定颈动脉-股动脉的脉搏波速度(C-FPWV)。用B超测定颈动脉内-中膜厚度,同时检测其身高、体重、血压、血糖、血脂水平,并计算体质指数(BMI)。结果CHD患者C-FPWV和对照组相比明显增高[(12.43±1.57)m/s与(10.85±1.98)m/s,p<0.01];CHD患者颈动脉IMT高于对照组[(0.78±0.17)m/s与(0.67±0.13)m/s,p<0.05]。Pearsion相关分析显示,CHD患者C-FPWV与体重指数、收缩压、脉压、年龄、总胆固醇、血糖、IMT呈显著正相关(分别r=0.25、r=0.29、r=0.30、r=0.31、r=0.26、r=0.28、r=0.30,p<0.01),与高密度脂蛋白胆固醇呈显著负相关(r=-0.25,p<0.01),而与舒张压、甘油三脂、低密度脂蛋白无相关性(p>0.05);IMT与年龄、收缩压、脉压、总胆固醇、血糖、PWV呈显著正相关(分别为r=0.35、r=0.26、r=0.29、r=0.23、r=0.30、r=0.33、p<0.01)。与高密度脂蛋白胆固醇呈显著负相关(r=-0.24,p<0.01)而与甘油三脂、低密度脂蛋白胆固醇无相关(p>0.05)。结论CHD患者C-FPWV及颈动脉IMT均明显升高,说明CHD患者已经存在明显的大动脉结构和功能改变,PWV变化及颈动脉IMT和年龄、收缩压、脉压、血糖、血脂有一定的关系。
