Comment<br />

The aetiology of the heart failure in this case is uncertain.<br />

Although ischaemia <strong>and</strong> hypertension may be playing a<br />

part, the diffusely poorly contracting myocardium suggests<br />

the possibility of diffuse cardiomyopathy, <strong>and</strong> the raised<br />

γ-glutamyltranspeptidase <strong>and</strong> triglyceride levels point to<br />

the possibility of alcohol excess. If this is the case, <strong>and</strong> if it is<br />

corrected, this could improve the blood pressure, dyslipidaemia<br />

<strong>and</strong> gout, as well as cardiac function. In the long<br />

term, allopurinol should be substituted for the NSAID, but if<br />

done immediately this is likely to precipitate an acute<br />

attack. Aspirin should be taken (for its antiplatelet effect,<br />

which may not be shared by all other NSAIDs). Treatment<br />

with a fibrate would be useful for this pattern of dyslipidaemia,<br />

but only after establishing that it was not alcoholinduced.<br />
