肺炎支原体肺炎患儿血清心肌酶临床分析

目的 研究血清心肌酶对肺炎支原体(MP)肺炎急性期患儿是否有心肌损害的诊断价值.方法 测定48例MP肺炎患儿(MP肺炎组)血清肌酸激酶同工酶MB(CK-MB)、乳酸脱氢酶(LDH)和天冬氨酸氨基转移酶(AST)的变化.以48例健康儿童作为对照(对照组).结果 MP肺炎组急性期血清心肌酶AST(37.18±6.15)U/L、LDH(294.10±46.20)U/L、CK.MB(84.50±13.70)U/L,明显高于对照组的(25.14±10.50)、(140.50±76.21)、(19.50±4.10)U/L,差异均有统计学意义(P＜0.01).MP肺炎组恢复期血清心肌酶较急性期明显下降,但CK-MB(27.80±8.40)U/L]、LDH(189.50±69.73)U/L]仍高于对照组(P＜0.01或＜0.05).结论 MP肺炎急性期有不同程度的心肌损害,血清CK-MB作为MP肺炎心肌损害的生化指标特异性强,治疗MP肺炎时应注意心肌损害,及时给予保护心肌治疗.

Clinical analysis of activity of serological myocardial enzymes in children With mycoplasma pneumonia

Objective To evaluate the diagnostic value of myocardial enzymes on the cardiac muscle injury for the children with acute mycoplasma pneumonia(MP).Method The levels of phosphocreatine kinase-MB(CK-MB),lactate dehydrogenase(LDH),aspartate aminotransferase(AST)in 48children with MP(MP group)were measured,48 normal children served as control group.Results The levels of AST,LDH,CK-MB were(37.18±6.15),(294.10±46.20),(84.50±13.70)U/L in acute stage in MP group,they were higher than those in control group(25.14±10.50),(140.50±76.21),(19.50±4.10)U/L](P＜0.01).All the values above was descended in recovery phase in MP group,but the values of CK-MB(27.80±8.40)U/L]and LDH(189.50±69.73)U/L]were still higher than those in control group(P＜0.01 or＜0.05).Conclusions Children with MP may combine myocardial injuries and CK-MB isa parameter to diagnose the damage.Protection therapy for cardiac muscle should be performed on the children with MP.
