Abstract:

Objective To investigate the predictive value of neutrophil count combined with serum uric acid (SUA) on myocardial injury in patients with acute carbon monoxide poisoning (ACOP). Methods A total of 114 ACOP patients who were hospitalized in the Department of Gastroenterology at the First Affiliated Hospital of Jinzhou Medical University from January 2021 to June 2022 were enrolled. Patients were allocated to a myocardial injury group ( n=72) and a non-myocardial injury group ( n=42) based on whether there was an increase in cardiac troponin I (cTnI) within 24 hours of admission. Clinical data of two sets were compared. Multivariate binary logistic regression analysis was employed to assess independent risk factors for myocardial injury in ACOP patients. Receiver operating characteristic curve analysis was performed to analyze the predictive value of relevant indicators in these patients. Results There was no significant difference in gender, hypertension history, diabetes history, smoking history and body temperature at admission between the two groups ( P>0.05). Compared with the non-myocardial injury group, the myocardial injury group had significantly higher age, neutrophil count levels, blood creatinine levels, and higher SUA levels ( P<0.05). Binary multivariate logistic regression analysis showed that age, neutrophil count, and SUA were independent risk factors for myocardial injury in ACOP patients. The cutoff values of neutrophil count and SUA for predicting myocardial injury in ACOP patients were 9.55×109/L and 325 μmol/L, respectively. The sensitivity and specificity of neutrophil count combined with SUA in predicting myocardial injury in ACOP patients were 68.1%, 73.8%, respectively, and 0.737 for the area under the curve (AUC), 0.419 for Jordan index. Conclusion Age, neutrophil count, and SUA are independent risk factors for myocardial injury in ACOP patients. The combination of neutrophil count and SUA has certain value in predicting myocardial injury in ACOP patients.
