【目的】探讨小儿上呼吸道感染并心肌受累的情况及其高危因素。【方法】将本院2009年1月—2009年5月207例上呼吸道感染患儿分为心肌受累组和非心肌受累组,对性别、年龄、体温、C反应蛋白、白细胞计数、支原体IgM抗体、衣原体IgM抗体等指标进行比较。【结果】心肌受累组84人,占40.60%,非心肌受累组123人,占59.40%。两组在性别、年龄、体温、白细胞计数上差异无统计学意义,在C反应蛋白、支原体IgM抗体、衣原体IgM抗体上差异有统计学意义,经Logistic回归分析,支原体IgM抗体阳性与上呼吸道感染并心肌受累密切相关。【结论】心肌受累在入院上呼吸道感染患儿中发生率较高,支原体感染是其危险因素。
【Objective】 To investigate the situation and risk factors of pediatric upper respiratory tract infection and myocardial involvement. 【Methods】 A total of 207 cases of upper respiratory tract infection in our hospital from January 2009 to May 2009 were divided into myocardial involvement group and non-cardiac involvement group, and gender, age, body temperature, C-reactive protein, leukocyte count, mycoplasma IgM antibody , Chlamydia IgM antibody and other indicators were compared. 【Results】 There were 84 patients in the myocardial involvement group, accounting for 40.60%, 123 in the non-cardiac muscle group, accounting for 59.40%. There was no significant difference in gender, age, body temperature and white blood cell count between the two groups. There were significant differences in C-reactive protein, mycoplasma IgM antibody and Chlamydia IgM antibody. Logistic regression analysis showed that mycoplasma IgM antibody was positive with upper respiratory tract infection And myocardial involvement is closely related. 【Conclusion】 The incidence of myocardial involvement is high in children with upper respiratory tract infection, and mycoplasma infection is the risk factor.
