Abstract:
Objective:To investigate the value of high-sensitivity cardiac troponin I (hs-cTnI) and soluble suppression of tumorigenicity 2 (sST2) in predicting cardiac complications of severe acute organophosphorus pesticide poisoning (SAOPP) .Methods:All 274 SAOPP patients from September 2014 to February 2019 were selected. According to the results of hs-cTnI detection, the patients were divided into non-elevated troponin group (78 cases) and troponin elevation group (196 cases) at 1 hour after admission. 3 days after admission, there were 109 cases of complication and 165 cases of non-complication according to the presence or absence of cardiac complications. The changes of hs-cTnI, sST2, N-terminal B-type brain natriuretic peptide (NT proBNP) , acute physiology and chronic health (APACHE-Ⅱ) , cholinesterase activity, left ventricular ejection fraction (LVEF) , short axis shortening rate (FS) were observed and analyzed. The predictive value of hs-cTnI and sST2 were evaluated by receiver operating characteristic curve (ROC) analysis.Results:The sST2 level in patients with troponin elevation group was significantly higher than that in non-elevated troponin group ( P<0.05) . Compared with the non-complication and non-elevated troponin group, the patients with non-complication and troponin elevation group had elevated hs-cTnI, sST2 and decreased cholinesterase ( P<0.05) . Compared with other groups, the hs-cTnI, sST2, NT-proBNP, and APACHE-Ⅱ scores in the complication and troponin elevation group were significantly increased, and cholinesterase was significantly reduced ( P<0.05) . In the non-complication group, LVEF and FS were in the normal range, and there was no significant difference between the groups ( P>0.05) . Compared with other groups, the LVEF and FS of patients with elevated troponin in the complications group were significantly decreased ( P<0.05) . Correlation analysis showed that hs-cTnI and sST2 were positively correlated in patients with SAOPP complications ( r=0.725, P<0.01) . hs-cTnI, sST2 and APACHE-Ⅱ scores were positively correlated in the complications group ( r=0.846, 0.885, P<0.01) . ROC results showed that the areas under the curve for predicting SAOPP secondary heart damage of hs-cTnI (1 hour after admission) and sST2 (3 days after admission) were 0.945 and 0.833, respectively. Conclusion:hs-cTnI and sST2 may have important clinical value in the early diagnosis and prognosis evaluation of patients with SAOPP secondary cardiac damage.
