Screening for left ventricular systolic dysfunction using GP-reported ECGs.

Background: Diagnostic echocardiography has poor access for patients with suspected heart failure. Pre-echocardiography screening with electrocardiograms (ECGs) is recommended as a means of targeting this scarce resource. There are data to support this policy when ECGs are interpreted by cardiologists but not by GPs.

A critical re-appraisal of different ways of selecting ambulatory patients with suspected heart failure for echocardiography.

Background: ECG and BNP have been assessed as screening tests for LVSD and heart failure. However, echocardiography also provides information about valvular disease and LVH. We assessed how good these screening tests are in identifying whether the subsequent echocardiogram will have any significant abnormality.

B-type natriuretic peptide as an alternative way of assessing total cardiovascular risk in patients with diabetes mellitus.

Cardiovascular risk scores are available but are often not calculated in busy clinics for numerous practical reasons. B-type natriuretic peptide (BNP) may be an alternative way of identifying subjects who have a high total cardiovascular risk score. We compared BNP level with Framingham 10-year Risk Scores for coronary heart disease and stroke and New Zealand Cardiovascular Risk Scores in 231 patients who had type 2 diabetes and no preexisting coronary heart disease or stroke.
