Abstract

Objectives : To determine whether blood natriuretic peptide concentrations are helpful in identifying or excluding left ventricular systolic dysfunction in stable survivors of acute myocardial infarction.

Design : Comparison of blood natriuretic peptide concentrations with echocardiographic assessment of left ventricular systolic function in a general practice population.

Setting : Practices in Western District of Glasgow audit group.

Subjects : 134 long term survivors of myocardial infarction recalled for echocardiography as part of a primary care secondary prevention audit.

Main outcome measures : Area under the receiver operating curve for brain natriuretic peptide and N-terminal atrial natriuretic peptide.

Results : Brain natriuretic peptide was of some diagnostic utility in identifying the minority of subjects with severe left ventricular dysfunction (area under curve=0.73) but was unable to discriminate between patients with moderately severe dysfunction and those with preserved left ventricular function (area under curve for moderate or severe dysfunction=0.54). The corresponding values forN-terminal atrial natriuretic peptide for severe and moderate or severe dysfunction were 0.55 and 0.56 respectively.

Conclusions : Blood natriuretic peptide concentrations are not useful in identifying important left ventricular systolic dysfunction in stable survivors of myocardial infarction.
