Diagnostic and predictive value of troponin I hy persensitive C-reactive protein and lactic acid in viral myocarditis

Objective To explore the diagnostic and predictive value of tropenin I,lactic acid and hypersen-sitive C-reactive protein（hs-CRP） in viral myocarditis. Methods Troponin I ,hs-CRP,lactic acid blood levels in dif- ferent time were measured in 88 patients with acute viral myocarditis （54 cases） or acute upper respiratory infectious （34 cases）. Troponin I level in patients with severe 39 cases and mild VMC 15 cases were compared. Results Troponin I level of VMC group was （0.59 ± 0.10） ng/L, and significantly higher than that of acute upper respiratory infection group [ （0.10±0.08 ） ng/L ] （ t = 2.79, P 〈 0.05 ）. And higher lactic acid and hs-CRP level were observed at different period （ t = 2.71,2.48, all P 〈 0.05 ）. Conclusion Troponin I could help diagnose VMC predict the severity of myocarditis to some extent. Lactic acid and hs-CRP could also reflect imflammation injury of VMC.
