Abstract:
Objective To study the early diagnostic value of high-sensitivity cardiac troponin Ⅰ(hs-cTnI) and soluble growth stimulating gene 2 protein (soluble suppression of tumorigenicity 2,sST2) in myocardial injury of acute organophosphorus pesticide poisoning (AOPP).Methods Totally 168 AOPP patients hospitalized from March 2014 to October 2018 were divided into the mild group (n=45),moderate group (n=55) and severe group (n=68).Another 30 healthy persons were served as the control group.The levels of cTnI,hs-cTnI,N-terminal B-type natriuretic peptide(NT-proBNP) and sST2 were detected at 4 h and 12 h after admission.SPSS 21.0 was used for statistical analysis.The measurement data were expressed by mean±standard deviation,two groups were compared by LSD-t test,and the multigroup comparison was made by single factor analysis of variance (ANOVA).The correlation analysis by Spearman correlation test (P＜0.05).Results At 1 h after admission,the hs-cTnI of AOPP patients with different degrees of poisoning was higher than that of control group,and that of severe group was higher than that of mild to moderate group.Comparison between groups was statistically significant (P＜0.05).However,there was no significant difference in the cTnI level (P＞0.05).At 4 h and 12 h after admission,the levels of cTnI and hs-cTnI increased with the increase of poisoning degree and the extension of time,and their level at 12 h after admission were significantly higher than those at 4 h after admission,with statistically significant difference between the two groups (P＜0.05).At 1 h after admission,the level of sST2 in the poisoned patients was higher than that in the control group,and the level in the severe group was higher than that in the mild to moderate groups.At 4 h and 12 h after admission,the level of sST2 was increased significantly,especially in the severe group.The level of sST2 at 12 h after admission was significantly higher than that at 4 h after admission (P＜0.05).The concentration of NT-proBNP was in normal range 1 h after admission,increased gradually at 12 h after admission,and the level of NT-proBNP in the severe group was significantly higher than that in the other groups (P＜0.05),and comparison between the groups was significantly different (P＜0.05).The correlation analysis showed that there was a positive correlation between hs-TnI and sST2 in AOPP patients (r=0.776,P＜0.01).hs-TnI and sST2 was positively correlated with the severity of AOPP (r=0.958,P＜0.01;r=0.844,P＜0.01).That is,the more severe the patient,the higher the concentration of hs-TnI and sST2,and the more serious myocardial injury.Conclusions Early detection ofhs-cTnI and sST2 levels in AOPP patients can identify early myocardial damage and objectively evaluate the extent of myocardial damage.
