B-type natriuretic peptide in the diagnosis of cardiac disease in elderly day hospital patients

heart failure is primarily a disease of elderly people. Current guidelines suggest all patients with suspected heart failure should undergo objective assessment, usually by echocardiography. In the UK resources are limited and not all patients have access to echocardiography. The electrocardiogram is widely used as a pre-screening investigation. Recently the natriuretic peptides have been shown to correlate well with left ventricular function, and evidence is accumulating which suggests that B-type natriuretic peptide may have a role in detecting cardiovascular disease. Elderly patients attending day hospital often have non-specific cardiovascular symptoms. B-type natriuretic peptide measurement in parallel with conventional electrocardiogram, may offer a novel method of identifying those with significant cardiac disease, which may warrant treatment. This study assessed the role of B-type natriuretic peptide and electrocardiogram in the detection of cardiac disease in patients attending Day Hospital.
