Abstract:
Objective To explore the predictive value of Tei index and plasma brain natriuretic peptide(BNP) on major adverse cardiovascular events(MACE) during long term follow up in the patients with anteriormyocardial infarction(MI).Methods A total of 238 patients with anterior MI were selected and divided into four groups according to the median of Tei index and BNP:G1 group(Tei≤0.66,BNP≤532.60 ng/mL,n=70),G2 group(Tei≤0.66,BNP＞532.60 ng/mL,n=51),G3 group(Tei＞0.66,BNP≤532.60 ng/mL,n=50) and G4 group(Tei＞0.66,BNP＞532.60 ng/mL,n=67).The follow up end was the MACE occurrence.Results There was a significant positive correlation between the Tei index and BNP(r=0.582,P=0.000).Tei entered the BNP regression equation(β=0.658,P＜0.05).The MACE-free survival rate had no statistical difference among 4 groups(x2 =9.975,P=0.019).The Cox regression analysis showed that Tei index and BNP were the independent predictive factors for MACE.Tei combined with BNP had stronger predictive value to MACE(AUC=0.781,95CI:0.721-0.841,P=0.000),its sensitivity was 72.52％ and specificity was 76.89％.Conclusion Tei combined with BNP has stronger predictive value for anterior MI during long term follow up.
