健康儿童318例冠状动脉内径超声心动图测定结果分析

目的 测量吉林省健康儿章超声心动图的冠状动脉内径正常值,并探讨其影响因素.方法 选择2010年5 -12月在吉林大学白求恩第一医院就诊的14岁以下健康儿童318例,并按年龄分为6个组,18 d～组、1岁～组、3岁～组、6岁～组、9岁～组、12～14岁组.测量各组儿童身高、体质量、收缩压、舒张压.采用TOSHIBA SSH - 880CV型多普勒超声诊断仪测定其左冠状动脉( LCA)、右冠状动脉(RCA)和主动脉根部(A0)内径.根据身高、体质量求得体表面积,并计算LCA/AO和RCA/AO值.采用SPSS17.0进行统计学分析.结果 各年龄组LCA与RCA均值比较差异均有统计学意义(Pa＜0.05).各年龄组组间LCA和RCA均值比较差异亦有统计学意义(F =84.347、88.885,Pa=0.000).LCA/AO值与RCA/AO值在各年龄组间差异均无统计学意义(F=0.112、0.717,P=0.990、0.611).Logistic一元线性回归分析结果显示LCA、RCA内径值与年龄、身高、体质量、体表面积、收缩压均呈正相关,对以上相关因素进行Logistic多元线性回归分析,结果显示年龄、体表面积与冠状动脉内径相关性最强.结论 冠状动脉内径与AO内径的比值是判断冠状动脉扩张的理想指标,对指导临床工作有重要作用.
