Abstract:
Objective To investigate the changes and significance of serum N-terminal pro-brain natriuretic peptide ( NT-proBNP) levels in mice model with viral myocarditis( VMC) . Methods 100 Balb/c mice were randomly di-vided into VMC group ( n=60 ) and control group ( n=40 ) . Mice in VMC group were injected intraperitoneally coxsackievirus B3 ( CVB3 ) , while mice in control group were treated with the same amount of virus-free DMEM cul-tivate liquid. 10 mice of each group were sacrificed on 3, 7, 14, and 28th day after VMC modeling and their blood and heart tissues were collected. The serum NT-proBNP levels in two groups of mice were detected by ELISA. Pathological changes in myocardial tissue were examined with hematoxylin and eosin stain. The relationship be-tween serum NT-proBNP concentration and cardiac pathology score of VMC group at different time points were ana-lyzed. Results The serum NT-proBNP levels of VMC group were significantly higher than that of control group( P<0. 05 ) . There was a significant statistical difference between NT-proBNP levels of VMC group at different time points( P <0. 05 ) . The NT-proBNP level was positively correlated with myocardial histopathology scores ( r =0. 829 , P<0. 05 ) . Conclusion Serum NT-proBNP levels may reflect severity of myocardial injury in mice with VMC. NT-proBNP can be used as one of serum indicators to judge the risk stratification in mice with VMC.
