幼儿上呼吸道感染心肌酶谱检测的临床价值

目的探讨心肌酶谱检测在幼儿上呼吸道感染中的临床价值。方法随机选择81例上呼吸道感染住院患儿进行肌血清酶谱的检测,根据每年上呼吸道感染次数分为反复上感组与普通上感组(对照组),再根据是否合并高热分为上高热组与上感组(对照组)进行临床观察。结果上感热组患儿心肌血清酶学指标(AST、LDH、CPK、CK-MB、α-HBDH)相应高于体温在39℃以下者,差异有统计学意义(P<0.01),反复上感组患儿心肌血清酶学指标(AST、LDH、CPK、CK-MB、α-HBDH)比普通上感组相应增高,二组比较差异有统计学意义(P<0.01)。经综合临床资料,5例诊断亚临床心肌炎,3例疑诊心肌炎。结论上感合并高热及反复上感患儿心肌细胞有不同程度的损伤,常规检测其心肌血清酶谱对早期发现亚临床心肌炎有重要价值。

Objective To explore the clinical value on the detection of myocardial enzymes in the upper respiratory tract infection. Methods Randomly selected 81 cases of upper respiratory tract infection in children hospilalized for muscle enzymes in serum test, according to the number of upper respiratory tract infection/flu last year repeatedly divided into groups with common sense on the group （control group）, based on whether or not the merger divided into high high group with a sense of the group （control group） to conduct clinical observation. Results Upper respiratory tract infection in children with high fever group of cardiac enzyme levels indicators （AST, LDH, CPK, CK-MB, α-HBDH） were higher than the one whose temperature is below 39℃, the difference was statistically significant （p〈0.01）, again on Respiratory tract infections in children with cardiac serum enzyme group of indicators （AST, LDH, CPK, CK-MB, α -HBDH） than the ordinary upper respiiatoty tract infection group corresponding increase in the two groups had a significant difference （p〈0.01 ）. After a comprehensive clinical data, 5 cases of sub-clinical diagnosis as myoearditis, 3 cases of suspected myocarditis. Conclusion Upper respiratory tract infection and high fever combined upper respiratory tract infection in children with recurrent myocardial cells have varying degrees of damage, its conventional detection of serum cardiac enzymes for the early detection of subclinical myocarditis significant value.
