Can heart failure be diagnosed in primary care?

Use of chest x-ray in diagnosing heart failure

In an otherwise excellent commentary[1] (Can heart
failure be diagnosed in primary care? ) on the article by
Lyn Caruana and colleagues[2] , Prof. Richard Hobbs
fails to mention the value of the chest X-ray. As every
medical student knows the chest X-ray provides
information on cardiac size and the major cardiac
structures, and more fundamentally on any respiratory
cause of breathlessness. It is even more extraordinary
that in the article by Caruana et al, no mention of the
chest X-ray in the diagnostic process is made in a
study which was especially focussing on excluding
other causes of the patients symptoms.

The current obsession with open-access
echocardiography is tending to unnerve GP’s who feel
that they cannot now make the diagnosis of heart
failure without demonstrating abnormal left ventricular
function. In fact the vast majority of patients can be
diagnosed and treated with a knowledge of the past
history, clinical findings, chest X-ray and ECG[3] .

Our own experience of open-access echocardiography
over a two year period was that it added very little to the
diagnostic process for those in primary care, except in
the presence of a heart murmur[4] . Given the rising
demands for specialist technician and medical time, it
is neither realistic nor desirable to use
echocardiography as a screening test for heart failure.
BNP may prove better [3], but surely the first test in
primary care for a breathless patient should be a chest
X-ray.
