轻度营养不良婴幼儿肺炎的心肌酶谱变化及临床意义

Variations of blood serum myocardial enzymes in mild malnutritronal infants and young children with pneumonia and their clinical significance

目的研究轻度营养不良儿患肺炎后并发心肌损害的发生情况,探讨两者之间的关系。方法对笔者所在医院2007年10月～2009年10月儿科住院的肺炎患儿进行年龄、身高、体重、腹壁皮下脂肪厚度等各项指标的检测及心肌酶的检验,根据诊断标准判断并发心肌损害的发病率。抽取6个月～3岁婴幼儿肺炎患儿,营养正常儿30例、轻度营养不良28例,排除中及重度营养不良、心肌炎及其他全身性疾病者。结果轻度营养不良组与营养正常儿组的心肌酶异常(活性增高)率及心肌酶活性增高程度比较有显著性差异。结论轻度营养不良儿肺炎后心肌损害概率及损害程度明显高于营养正常儿。

Objective To study the incidence rate of mild malantritional infants and young children with pneumonia complicated by myocardial damage and to explory the relationship between them. Methods Fifty - eight infants and young children between six months and three years old with pneumonia enrolled were divided into groups according to their condition of nutrition from Oct 2007 to Oct 2009 in haspital,excluding moderate and severe malnutrition,myocarditis and other diseasea. Twenty - eight mild malnutritional infants and young children in one group and thirty normotrophic control in another group. It was used to detect the indices of age, boby height, weight, fat thickness of abdominal wall and serum cardiac enzyme and to judge the incidence rate complicated by myocardial damage according to diagnostic criteria. Results Serum levels of cardiac enzyme were significantly higher in mild malnutritional infants and young children with pneumonia than those in the controls. Conclusion That the incidence rate and the severity of mild malnutritional infants and young children with tmeumonia corn -plicated by myocardial damage is apparently higer than that in normotrophic control.
