RESUMO
ObjectiveTo explore the diagnostic and predictive value of troponin Ⅰ,lactic acid and hypersensitive C-reactive protein(hs-CRP) in viral myocarditis.MethodsTroponin Ⅰ,hs-CRP,lactic acid blood levels in different time were measured in 88 patients with acute viral myocarditis(54 cases) or acute upper respiratory infections (34 cases).Troponin Ⅰ leyel in patients with severe 39 cases and mild VMC 15 cases were compared.ResultsTroponin 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).ConclusionTroponin 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.
