Relationship of serum albumin with BNP,hs-CRP and LVEF in patients with acute myocardial infarction / 中国综合临床

ABSTRACT

Objective To study the changes of serum albumin and its relationship with B-Type Natriuretic Peptide(BNP),High sensitivity C-reactive protein(hs-CRP)and left ventricular ejection fraction (LVEF) in patients with acute myocardial infarction(AMI).Methods Serum levels of albumin,BNP,hs-CRP at baseline were analyzed in 95 patients with AMI,and LVEF were measured by echocardiography.All AMI patients were divided into 2 groups based on the values of serum albuminthe hypoalbuminemia group and the normal albuminemia group.Fifty patients without coronary artery disease were selected as controls.The correlations between serum albumin and BNP,hs-CRP,LVEF were analyzed.Results Serum albumin in AMI patients was lower than that in the controls[(38.45±4.60) g/L vs.(43.15±3.11) g/L ;t =8.53,P ＜ 0.001].BNP and hs-CRP levels in the hypoalbuminemia group were higher than that in the normal albuminemia group [(5.24±1.71)ng/L vs.(4.17±1.61) ng/L;t =2.660,P =0.009;(1.64±0.93) mg/L vs.(1.13±1.03)mg/L;t =2.159,P =0.045].LVEF in hypoalbuminemia group was lower than that in the normal albuminemia group[(49.10±11.63) ％ vs.(54.63±9.60) ％ ; t =2.268,P =0.025].Levels of serum albumin were negatively correlated with BNP and hs-CRP in AMI patients(r =-0.465,P ＜0.001 ; r =-0.391,P ＜ 0.001).Levels of BNP were positively correlated with hs-CRP(r =0.492,P ＜ 0.001).LVEF was negatively correlated with BNP values(r =-0.371,P ＜ 0.001).Conclusion Hypoalbuminemia is associated with the prognosis of AMI and may be an important predictor of adverse outcome in patients with it.
