Abstract:
Objective To explore the clinical significance of determination of the serum levels of brain (B-type) natriuretic peptide (BNP) and high-sensitivity C-reactive protein (hs-CRP) in patients with acute myocardial infarction (AMI).Methods The clinical data of 60 cases with AMI and 50healthy controls were analyzed retrospectively.The BNP and hs-CRP levels were analyzed in AMI and Killip class,and their relationship with prognosis was investigated.Results The serum levels of BNP,hs-CRP and creatine kinase (CK)-MB) were higher in AMI group than in control group (all P＜0.05),and the levels were lowered after treatment (P＜0.05).The correlation analysis indicated that BNP and hs-CRP had positive correlations with CK-MB (r=0.892 and 0.683,all P＜0.05),and increased along with the severity of Killip classification.The 8 cases (13.3 % ) died,and single factor analysis revealed that BNP (≥56.1 pmol/L),hs-CRP (≥9.0 mg/L),CK-MB (≥75.1 U/L) and Killip classification (grade Ⅲ and Ⅳ) were the poor prognostic factors (P＜0.05).Conclusions The elevation of BNP and hs-CRP level is correlated with the severity of AMI,and could be used to evaluate the AMI patients' diagnosis and prognosis.
