An audit of echocardiograms in acute left ventricular failure
Insights
Many heart failure patients miss echocardiograms, a key diagnostic tool. This audit reveals underutilization of echocardiography and angiotensin-converting enzyme (ACE) inhibitors, impacting patient care and prognosis.
Area of Science:
- Cardiology
- Diagnostic Imaging
- Clinical Audit
Background:
- Echocardiography is crucial for diagnosing heart failure and guiding treatment.
- Acute left ventricular failure requires timely and accurate diagnostic assessment.
Purpose of the Study:
- To audit the use of echocardiography in patients admitted with acute left ventricular failure.
- To assess the adherence to guidelines regarding echocardiography and ACE inhibitor prescription.
Main Methods:
- Retrospective audit of 100 case notes of patients admitted with acute left ventricular failure.
- Review of echocardiogram utilization and angiotensin-converting enzyme (ACE) inhibitor prescription rates.
Main Results:
- 26% of patients admitted with acute left ventricular failure did not undergo echocardiography.
- Among those with echocardiograms, 68% showed reduced systolic function (mean ejection fraction 42%).
- Despite clear indications, some patients were not prescribed angiotensin-converting enzyme (ACE) inhibitors.
Conclusions:
- There is a significant gap in the utilization of echocardiography for heart failure diagnosis and prognosis.
- Suboptimal prescription of angiotensin-converting enzyme (ACE) inhibitors (ACE inhibitors) is evident, potentially affecting patient outcomes.
Abstract:
All patients with heart failure should have an echocardiogram to establish a diagnosis, both to aid treatment as well as for prognostic reasons. An audit of 100 case notes of patients admitted with acute left ventricular failure over a 12-month period found that 26 patients had not had an echocardiogram. Of the 74 who did have an echocardiogram 68 patients had reduced systolic function (mean ejection fraction 42%). Almost all (93%) were commenced on an angiotension-converting enzyme (ACE) inhibitor. Those who did not receive an ACE inhibitor had no contraindications to these drugs. Seventeen patients had a confirmed myocardial infarction. Of these, 11 had an echocardiogram and 10 were discharged home on an ACE inhibitor. Despite appropriate indications some patients are deprived of echocardiography as well as the benefits of ACE inhibitors.
