Abstract:
Objective:To explore the correlation between myocardial damage and vascular endothelial growth factor (VEGF), red blood cell distribution width (RDW), and myocardial enzyme spectrum in children with severe mycoplasma pneumoniae pneumonia.Methods:Sixty children with severe mycoplasma pneumoniae pneumonia and myocardial damage admitted to Jining Medical University from January 2019 to December 2020 were selected as the observation group, and 60 children with severe mycoplasma pneumoniae pneumonia admitted during the same period were selected as the control group. The differences in clinical data and imaging features between the two groups were compared. Pearson correlation analysis was used for correlation analysis; The logistic regression method was applied to analyze the influencing factors of myocardial damage in children with severe mycoplasma pneumoniae pneumonia. The value of VEGF and RDW in predicting myocardial damage in children with severe mycoplasma pneumoniae pneumonia was analyzed using receiver operating characteristic (ROC) curves.Results:The levels of C-reactive protein (CRP), procalcitonin (PCT), VEGF, RDW, creatine kinase isoenzyme (CK-MB), creatine kinase (CK), cardiac troponin I (cTnI), and lactate dehydrogenase (LDH) in the observation group were significantly higher than those in the control group (all P<0.05), and the duration of fever, application of macrolide drugs, and glucocorticoid application time were significantly longer than those in the control group (all P<0.05). There was no statistically significant difference in pulmonary imaging characteristics between the observation group and the control group (all P>0.05). The VEGF and RDW in the observation group were positively correlated with CK-MB and cTnI (all P<0.05). Logistic regression analysis showed that duration of fever, VEGF, RDW, and duration of macrolide drug use were the influencing factors for myocardial damage in children with severe mycoplasma pneumoniae pneumonia (all P<0.05). The area under the ROC curve of VEGF combined with RDW in predicting myocardial damage in children with severe mycoplasma pneumoniae pneumonia was 0.899, significantly higher than that predicted by VEGF and RDW alone (all P<0.05). Conclusions:The serum VEGF and RDW levels in children with severe mycoplasma pneumoniae pneumonia accompanied by myocardial damage are elevated and positively correlated with myocardial enzyme spectrum indicators, which has certain application value in predicting myocardial damage.
