Common Error Analysis of Brain Natriuretic Peptide and Left Ventricular Ejection Fraction in Assessment of Left Ventricular Function

Objective To observe the evaluation of effect on left heart function between plasma brain natriuretic peptide(BNP) level and left ventricular ejection fraction(LVEF),analyze the cause of common error.Methods Collect 320 patients of different cardiac function level,They were assigned separately to groups according to BNP and LVEF.Using Biosite company brain natriuretic meal kits and Triage BNP tester for BNP detection.Results In BNP(ng/L) group,BNP level in each group,the differences were statistically significant(P0.05);BNP≥ 100ng/L group and the other group LVEF value,the difference was statistically significant(P0.05).LVEF(%) group,the levels of BNP in all groups,LVEF,LVEDd,the differences were statistically significant(P0.05);where LVEF≥50% in 270 cases,BNP400ng/L in 247 cases(91.5%).Conclusion All kinds of detecting techniques should be comprehensive analysis,Clinical doctors can′t overly dependent on a certain detection.
