高血压与不同部位动脉病变的关系

Investigation on Relationship between Hypertension and Vascular Lesion of Different Segments

对１２０例高血压（ＥＨ）患者外周动脉和动态血压监测发现，外周动脉病变与ＥＨ发展有关，不同部位动脉病变对血压升高的反应不同，颈动脉对血压的变化比较敏感，随收缩压尤其２４ｈ动态血压的升高，颈动脉病变随之增加，下肢动脉不因血压的改变而变化。对４６例接受冠脉造影检查的轻型ＥＨ患者进行活动平板运动负荷试验，发现下肢和冠状动脉多存在运动后血管扩张反应受损，这种动脉异常与血压的变化无明显关系。

Peripheral artery and 24 hour ambulatory blood pressure were measured in 120 patients with essential hypertension(EH).The results suggested that peripheral arterial disease associate with the development of EH. Vascular disease of different segments made distinctive response to blood pressure(BP).The carotid artery was sensitive to change of BP.The higher systolic BP especially in ambulatory systolic BP,the higher incidence of diseased carotid artery was.But diseased arteries of lower extremity were not related with changes of BP.Treadmill exercise test was performed in 46 patients with mild EH and being ready to undergo angiocardiography.Postexercise vasodilation of impaired lower extremity and coronary arteries was found in most patients.But the relationship between the vascular abnormality and changes of BP was not significant,also.
