Comprehensive analysis on variation of cardiac enzyme and troponin induced by acute organophosphorous poisoning



Comprehensive analysis on variation of cardiac enzyme and troponin induced by acute organophosphorous poisoning



Zhonghua Lao Dong Wei Sheng Zhi Ye Bing Za Zhi 30(6): 452-455



To discuss the diagnostic value of cardiac enzyme and troponin in acute organophosphorus pesticide poisoning (AOPP). A retrospective study was performed in the document published in domestic journals and PubMed from 1979 to 2010. The data of the cardiac enzyme and troponin were collected. Statistical analysis was conducted with one-way ANOVA and rank sum test. 2129 cases with AOPP were enrolled. The levels of creatine kinase (CK), creatine kinase-MB (CK-MB) and cardiac troponin I (cTnI) in milder, moderate and severe poisoning groups were significantly elevated compared by the healthy control group (P < 0.05). The differences were also dramatic among three patients groups (P < 0.05). The ratios of CK-MB to CK in both moderate and severe groups were significantly lower than in healthy controls (P < 0.05). The levels of CK, CK-MB and cTnI were higher especially in patients with intermediate myasthenic syndrome (IMS) than patients without IMS. Meanwhile, the levels of CK and CK-MB were elevated in patients with respiratory failure compared by non-failure ones, but decreased in the ratios of CK-MB to CK (P < 0.05). The elevation of CK and CK-MB in serum could not be judged as the criteria of myocardial damage in AOPP, the ratio of CK-MB to CK were more valuable; the value of cTnI in myocardial damage was still in suspect. CK, CK-MB and cTnI could be used as auxiliary criteria of AOPP classification.
