| 目的：探讨老年人高血压前期糖耐量降低（IGT）对血管内皮功能和颈动脉粥样硬化的影响。方法：选择2013 年1 月至2014
年1 月在我院门诊、住院和体检中心纳入的60 岁以上志愿者240 例，依据血压、血糖水平将志愿者分为四组，单纯高血压前期
（PH）组，单纯IGT（IGT）组，高血压前期并发IGT（PH&IGT）组，正常对照（NC）组，每组均为60 例。检测颈动脉内中膜厚度（IMT）
和内皮依赖性血管舒张功能（FMD）并进行相关性分析。结果：与NC组相比，IMT 在PH组、IGT组和PH&IGT组显著升高[(0.74±
0.09)mm、(0.76± 0.12)mm、(0.96± 0.14）mmvs（0.57± 0.08）mm，均P<0.05]，且PH&IGT组相比于PH组和IGT组进一步升高（P<0.05）；与
NC 组相比，FMD 在PH组、IGT 组和PH&IGT 组显著降低[(8.77± 2.56) %、(8.59± 2.37) %、(5.78± 2.11）%vs（12.48± 2.78）%，均
P<0.05]，且PH&IGT 组相比于PH组和IGT 组进一步下降（P<0.05）。直线相关分析显示，IMT 与FMD 呈显著负相关，相关性检验
有统计学意义（r=-0.843，P<0.01）。结论：高血压前期患者血管内皮功能受损，在高血压前期基础上的IGT 将会加剧血管内皮功能
障碍和动脉粥样硬化。 |

| Objective:To study the influence of impaired glucose tolerance(IGT) on endothelial function and carotid atherosclerosis
in elderly patients with prehypertension.Methods:A total of 240 volunteers (age≥ 60 years old) in outpatient, inpatient and medical
center of Qingdao Haici Medical Group from January 2013 to January 2014 were selected and divided into normal control group(NC
group, n=60), prehypertension group(PH group, n=60), IGT group(n=60), prehypertension and IGT group(PH&IGT group, n=60) according
to the blood pressure and blood glucose level. The intima-media thickness (IMT) and flow mediated diameter (FMD) in the four
groups were detected, and their correlation was analyzed.Results:Compared with NC group, IMT in PH, IGT and PH&IGT groups significantly
increased [(0.74± 0.09)mm, (0.76± 0.12)mm and (0.96± 0.14)mm vs (0.57± 0.08)mm, all P<0.05]; IMT in PH&IGT group
significantly increased compared with PH and IGT group(P<0.05); FMD in PH, IGT and PH&IGT groups significantly decreased[(8.77±
2.56)%, (8.59± 2.37)%, and (5.78± 2.11)% vs (12.48± 2.78)%, all P<0.05], FMD in PH&IGT group significantly decreased compared
with PH and IGT group (P<0.05). Linear correlation analysis showed that FMD was negatively correlated with IMT (r=-0.843, P<0.01).Conclusion:Vascular endothelial function is obviously impaired in elderly patients with prehypertension, on the basis of which, IGT will
exacerbate the endothelial dysfunction and atherosclerosis. |
