急性冠状动脉综合征心电图特征与冠状动脉造影结果分析

目的对急性冠状动脉综合征心电图表现与冠脉造影所见冠脉病变特点进行对比分析,探讨心电图改变与冠脉病变和动脉硬化危险因素的关系。方法回顾分析2001-11～2004-12收治并经冠脉造影检查ACS病人的临床资料238例,平均年龄(61.9±13.7)岁,按年龄分为<70岁组和≥70岁组,对比两组心电图,造影所见病变特点以及危险因素组成。结果在除右室导联组以外的各导联组,单支病变≥70岁组明显少于<70岁组;≥70岁组双支病变和3支病变明显增多,下后壁组虽有增多,无统计学意义;高血压病比例组间无明显差异46.3%比53.1%,P>0.05;糖尿病比例≥70岁组明显多于<70岁组19.5%比58.26%,P<0.05;≥70岁组Tchol高于<70岁组(5.92±0.31)比(5.15±0.37),P<0.05;≥70岁组LDL低于<70岁组(5.31±0.22)mmol/L比(4.25±0.17)mmol/L,P<0.05;TG无明显差异(2.68±0.19)比(2.73±0.21),P>0.05;非致死性AMI在≥70岁组明显多于<70岁组;35%比65.5%,P<0.05;ST段下移的AMI≥70岁组明显多于<70岁组(11.6)%比(43.8)%;P<0.05。结论老年急性冠状动脉综合征患者的多支血管病变多见;ST段下移的急性心肌梗死更多见;高龄、糖尿病和心电图ST段下移多预示多支血管病变;危险因素方面高血压病组按年龄分组无明显差异;老年组,糖尿病、高甘油三酯增多,低于70岁组高胆

Comparative Analysis on ECG Characteristics of Acute Coronary Syndrome with Coronary Angiography

Objective To analyze the ECG characteristics of acute coronary syndrome(ACS) with coronary angiography comparatively and discuss the relationship of changes of ECG with risk factors of coronary lesion and arteriosclerosis.Methods The clinical data of 238 cases of ACS patient with coronary angiography were analyzed retrospectively.They were divided into two groups:group A(<70) and group B(≥70) and ECG and risk factors were analyzed.Results There were significant differences in group B that lower than group A in single branch and LDL level.There were significant differences in group B that higher than group A in branches lesion,diabetes,non-fetal AMI WITH P <0.05.Conclusion There were common in multiple branches lesion in senile ACS and AMI with ST segment decrease that predict the results with diabetes.There was no significant difference in age at hypertension group.The hyperglycemia,high cholesteroid and LDL in senile group.
