Abstract:
Objective To investigate the relationship between brain natriuretic peptide (BNP)and heart function in elderly patients with acute myocardial infarction.Methods All data were taken from the hospitalized cases with acute myocardial infarction from December 2008 to August 2010.100 patients aged from 60 to 97 were enrolled.The data were divided into 4 groups (group 1,24 cases; group 2,32 cases,group 3,23 cases; group 4,21 cases) respectively according to Killip's classification.Left ventricular function was measured by echocardiography.Plasma BNP was determined with enzyme immunoassay.Results Compared with non heart failure group and normal group,heart failure group had much higher plasma BNP concentrations.The plasma BNP level had positive correlation with left ventricular end diastolic diameter (r =0.27,P < 0.01) and left ventricular end-diastolic dimension (r=0.37,P<0.01),while,had a negative correlation with left ventricular ejection fraction (r =-0.38,P < 0.01).Conclusions Plasma BNP level was significantly elevated which could evaluate the heart function in elderly patients with acute myocardial infarction.
