目的 了解病毒性心肌炎 (VM)的心功能改变及相关因素。方法 对 15 2例病毒学确诊的心肌炎患儿测定其心功能 ,并分析心功能改变与抗心肌线粒体和心肌酶之间的关系。结果 超声心动图检查 ,VM患儿每搏射血指数显著低于健康儿童 ;左室侧壁射血分数、室间隔射血分数和左室射血率显著低于健康儿童 ;二尖瓣环收缩运动和舒张早期运动速度显著低于健康儿童。心功能下降与抗心肌线粒体抗体阳性与否无关 ,肌酸激酶同功酶(CK -MB)增高者心功能降低者多于CK -MB正常者。结论 部分VM患儿心功能降低 ,心功能降低与CK -MB增高与否有关 ,与抗心肌线粒体抗体阳性与否无关
Objective To understand the changes of cardiac function and related factors in viral myocarditis (VM). Methods Fifty-two children with viral myocarditis diagnosed were tested for cardiac function and the relationship between cardiac function and myocardial mitochondrial and myocardial enzymes was analyzed. Results Echocardiography showed that the PWV of children with VM was significantly lower than that of healthy children. The left ventricular ejection fraction, ventricular ejection fraction and left ventricular ejection fraction were significantly lower than those of healthy children. Mitral annulus contractions Movement and early diastolic velocity were significantly lower in healthy children. Decreased cardiac function and anti-myocardial mitochondrial antibody-positive or not, higher creatine kinase isoenzyme (CK-MB) decreased cardiac function more than CK-MB normal. Conclusions Some patients with VM have decreased cardiac function, decreased cardiac function and CK-MB increased or not, and anti-myocardial mitochondrial antibody-positive or not
