Clinical significance of TnI, hs-CRP and NT-proBNP in the diagnosis of myocardial damage in uremia patients

Objective:To study the clinical significance of troponinI(TnI),high sensitivity C reactive protein(hs-CRP)and N-terminal pro-brain natriuretic peptide(NT-proBNP)in the diagnosis of myocardial damage in uremia patients.Methods:114 uremia patients treated in our hospital from January 2017 to February 2019 were selected.According to whether myocardial damage occurred,patients were divided into two groups including uremia group(63 cases)anduremia myocardial damage group(51 cases).50 hospitalized patients with non-chronic kidney disease and non-cardiovascular disease in our hospital were selected as control group.The levels of TnI,hs-CRP and NT-proBNP in 1,3 and 7 days after admission were detected and compared.Meanwhile,the ecg indexes of left?ventricular?ejection?fraction(LVEF)and Thickness of the posterior wall of the left ventricle(LVPWd)were recorded and compared.Person correlation was used to analyze the correlation between the levels of TnI,hs-CRP,NT-proBNP and ecg indexes including LVEF and LVPWd.COX regression analysis was used to analyze the independent riskfactors affecting the clinical prognosis of uremia patients.Results:The levels of TnI,hs-CRP,NT-proBNP in the three groups were significantly different on 1,3,7 days after admission.The levels of the three indexes(TnI,hs-CRP,NT-proBNP)in uremia combined with myocardial damage group and uremia group were decreased with treatment.However,the levels of the three indexes(TnI,hs-CRP,NT-proBNP)in uremia combined with myocardial damage group were the highest(P<0.05).Compared with the other two groups,the LVEF of uremia combined with myocardial damage group was the lowest,while the LVPWd was the thickest,showing a significant difference(P<0.05).There was negativecorrelation between LVEF and TnI,hs-CRP,NT-proBNP levels.However,LVPWd was positively correlated with TnI,hs-CRP and NT-proBNP levels(P<0.05).COX regression analysis showed that TnI,hs-CRP,NT-proBNP levels,LVEF and LVPWd were the independent factors affecting the clinical prognosis of uremia patients Conclusion:The level of TnI,hs-CRP,NT-proBNP was dynamic change in the onset and treatment process in uremia combined with myocardial damage patients,which could be used for early diagnosis of uremia combined with myocardial damage.
