目的探讨血清肌酸激酶同工酶质量和肌钙蛋白I定量在急性一氧化碳中毒心肌损伤的临床意义。方法我院急性一氧化碳中毒患者76例,50例健康体检者作为对照。测定血清肌酸激酶同工酶质量和肌钙蛋白I水平。结果除CK-MB对照组与轻度中毒组无差异,其余各对照组及轻度中毒组比较中、重度组血清CK-MB和肌钙蛋白I水平均明显升高。结论血清cTnI和CK-MB的水平可作为判断ACOP程度的指标,但是CK-MB诊断ACOP合并心肌损伤特异性不高,它不能排除微小的心肌坏死,而cTnI可作为诊断ACOP伴心肌损伤的特异性指标,为正确判断ACOP合并心肌损伤提供可靠依据。
Objective To investigate the clinical significance of the serum creatine kinase isoenzyme mass and troponin I quantification in myocardial injury induced by acute carbon monoxide poisoning. Methods Acute carbon monoxide poisoning in our hospital 76 cases, 50 cases of healthy subjects as a control. Serum creatine kinase isoenzyme mass and troponin I levels were measured. Results In CK-MB control group and mild poisoning group there was no difference, the other control groups and mild poisoning group, moderate and severe serum CK-MB and troponin I levels were significantly higher. Conclusions The levels of cTnI and CK-MB in serum can be used as indexes to judge the degree of ACOP. However, the specificity of CK-MB in diagnosing ACOP complicated with myocardial injury is not high. It can not exclude the minor myocardial necrosis, while cTnI can be used as a specific diagnosis of ACOP with myocardial injury Sexual indicators, to provide a reliable basis for the correct judgment of myocardial infarction combined with ACOP.
