目的:分析小儿病毒性心肌炎的心功能改变及引起改变的因素。方法:研究对象源于该科2013年2~10月收治的病毒性心肌炎患儿170例作为研究组,再根据1∶2配对的方法选取健康儿340例作为对照组;测定心功能改变并探究影响因素。结果:病毒性心肌炎患儿的容量指标(SV、SI)、压力指标(LVEF、LPFR、ALVEF)、速度指标(二尖瓣MSV、MDV、血流PFVe、PFVa)均明显低于对照组,心功能改变与心肌酶谱相关性显著。结论:病毒性心肌炎患儿的心功能出现较大改变,且与心肌酶关系密切,建议临床给予足够关注。
PURPOSE: To analyze the changes of cardiac function in children with viral myocarditis and the factors causing them. Methods: The subjects were from 170 children with viral myocarditis admitted from February to October in 2013 in our hospital, and 340 healthy children were selected as the control group according to the method of 1: 2 matching. The changes of cardiac function were measured and explored Influencing factors. Results: The volume index (SV, SI), pressure index (LVEF, LPFR, ALVEF), velocity index (mitral MSV, MDV, PFVe and PFVa) in children with viral myocarditis were significantly lower than those in the control group Correlation of functional changes with myocardial enzymes was significant. Conclusion: The cardiac function of children with viral myocarditis is greatly changed, and is closely related to myocardial enzymes, it is recommended that clinical attention be given enough.
