Cardiologists and generalists have been reported to
diverge in terms of their self-reported use of angiotensin-converting enzyme (ACE) inhibitors, but information on their actual use of ACE
inhibitors has been lacking. In order to assess ACE inhibitor use in
patients with heart failure in a teaching hospital and any differences
between specialties we studied all patients in the Western Infirmary of
Glasgow between 1 April and 1 October 1996 with an echocardiogram
showing moderate or severe left ventricular systolic dysfunction
(n=236). We found that most patients were on
an ACE inhibitor (66%), 12% had been tried but found to be intolerant, 10% had not been tried because of a contraindication, but
12% had not been tried despite no contraindication. Of those on
treatment, 58% were on a dose used in a major survival study (38% of
all patients). Most patients were treated by a cardiologist (64%). Of
these, more were on an ACE inhibitor (77% vs
53%, p<0.01), fewer had been tried but found intolerant (11%
vs 18%), and fewer had never been tried
(11% vs 29%, p<0.01), irrespective of
whether they had a contraindication (5% vs
18%, p<0.01) or not (6% vs 12%). More
were on a dose used in a major survival study (48% vs 31%, p<0.05). We conclude that, despite
improvements over time, ACE inhibitors are still under-used, sometimes
without good reason. There are also differences in the use of ACE
inhibitors between cardiologists and generalists which may affect
outcome, and could affect resource utilisation.
