摘要
目的:探讨冠状动脉侧支循环对心肌缺血、左室功能的保护作用及对心律失常的影响。方法:随机选取188例冠心病患者选择性冠状动脉造影资料,分析其冠状动脉侧支循环不同程度开放情况。同时记录心电图ST段改变、彩色超声心动图LVEF、E/A比值及动态图心律失常情况。结果:其中81例冠状动脉侧支循环开放良好(A组),107例冠状动脉侧支循环开放不良(B组)。心肌缺血程度A组较B组轻,左室功能指标A组明显优于B组,A组心律失常发生率少于B组。结论:良好的冠状动脉侧支循环对心肌缺血、左室功能具有保护作用,并可减少心律失常的发生。
Objective:To explore the affect of side branch circulation of coronary arteries on ischemy of cardiac muscle,function pretection of left Ventricle and cardiac arrhymia.Methods:188 cases were selected and the data of arteriography,the open status of side branch circulation of coronary arteries,ST changes in electrocardigram,LVEF,E/A radio in color type B ultrasound were analyzed.Results:81 cases(group A) showed the good side branch circulation of coronary arteries and the another 107 cases showed the bad circulation.The ischemic degree of cardiac muscle was lighter in group A than that in group B.The function indeies of left ventricle in group A were suppirior to those in group B.The incidence of cardiac arrhymia in group A was lower than that in group B.Conclusion:The good side branch circulation of coronary arteries may pretect the cardiac muscle and the function of left ventricle and also reduce the of incidence of cardiac arrhymia.
