Abstract

Background: Chronic obstructive pulmonary disease (COPD) is commonly associated with cardiovascular comorbidity and this association may impact reciprocally on disease morbidity and mortality.
Statins and angiotensin-converting enzyme inhibitors (ACEi) are used for their effects on cardiovascular mortality reduction, but little is known on their effects on infective exacerbations of COPD.
Aims: To measure and correlate the use of statins, ACEi and hospital length of stay during COPD exacerbations.
Method: We conducted a retrospective analysis on all COPD exacerbative admissions in 2009 in a district general hospital in London.
Length of stay was measured from an inpatient database, and the use of statins and ACEi were collected from electronic discharge summaries.
Results: We identified 478 admissions (pertaining to 352 patients) specifically for COPD exacerbations. The median age of the patients was 73 years and 60.2% were males. The median admission time was 5 days. A higher proportion of patients with an admission of more than 5 days had concomitant prescriptions for statins and ACEi (43.5% and 33.3% respectively as compared with 34.4% and 28.3% for patients with an admission of ≤ 5 days).

Results
Length of stay<5 days>5 days
Patients on statins34.4%43.5%
Patients on ACEi28.3%33.3%


Conclusion: The use of statins and ACEi was higher in patients who required longer admissions for their COPD exacerbations. These findings may reflect disease severity and the presence of cardiac comorbidities, rather than an effect of statins and ACEi on COPD exacerbations.
