血管降钙素基因相关肽和内皮素改变在冠脉综合征中的意义

目的研究血浆降钙素基因相关肽(CGRP)和血管内皮素(ET)在急性冠脉综合征中的作用及二者的消长变化在急性冠脉综合征发病学中的意义.方法不稳定性心绞痛组30例,急性心肌梗塞组28例,对照组25例.对照组晨间空腹取血,心肌梗塞组入科时及一周后晨间取血,心绞痛发作时及缓解后次日晨取血.各取5ml,分别测定血浆CGRP及ET浓度.结果急性心梗组CGRP高于UA组及对照组,ET升高更显著,CGRP/ET比值下降;急性冠脉综合征发作时与缓解期比较,CGRP升高,ET升高更显著,CGRP/ET比值下降;不同类型急性冠脉综合征比较,CGRP及ET浓度MI组＞恶化型UA组＞初发型UA组CGRP/ET比值初发型UA组＞恶化型UA组＞MI组.结论 ET、CGRP变化与冠脉病变程度相关,CGRP、ET水平及其受体消长失衡在急性冠脉综合征发生发展过程中具有重要作用.

The Significance of Changes in Plasma Calcitonin Gene-related Peptide and Endothelin in Coronary Syndrome

AIM To investigate the significance of CGRP and ET in the coronary syndrome and the significance of their changes in the incidence of the acute coronary syndrome.Methods Group with UA group ( n =30), AMI group ( n =28), control group ( n =25) were established.In control group blood sample take on an empty stomach in the morning ,while group with AMI on hospitalization and after one week, group with UA at angina pectoris attack and after remission. The concentration of plasm CGRP and ET were measured .Results The plasm CGRP concentration in group with AMI was higher than that in group with UA and that in control group ,the plasm ET elevated markedly, while the rate of CGRP/ET decreased; Compared with that in the remission period of the acute coronary syndrome ,The plasm CGRP elevated, the plasm ET elevated markedly, while the rate of CGRP/ET decreased.Among defferent acute coronary syndrome ,the plasm CRGP and ET concentrantion was highest in AMI group,higher in group with accelerated UA, high in group with initial attack UA;the rate of CGRP/ET was highest in group with initial UA,higher in group with accelerated UA,high in group with AMI.Conclusions The changes of plasm CGRP and ET concentration are well correlated with the extent of coronary lesion, the level of plasm CGRP and ET and the imbanlance of thier receptor play an important role in the pathogenesis and development of acute coronary syndrome.
