OBJECTIVES: We sought to evaluate the common utilization of beta-blockers and angiotensin-converting enzyme (ACE) inhibitors or receptor blockers (RBs) in congestive heart failure (CHF).
BACKGROUND: We assessed the association between prescriptions of beta-blockers and ACE inhibitors or RBs within three months after hospitalization and mortality for newly diagnosed CHF in Alberta, Canada seniors (age 65 years and older).
METHODS: Administrative hospital discharge abstracts and drug data during October 1, 1994, to December 31, 1999, were analyzed.
RESULTS: There were 11,854 hospitalizations for newly diagnosed CHF. The use of beta-blockers within three months after hospitalization increased from 7.3% in 19941995 to 20.9% in 19992000. The use of ACE inhibitor or RBs within three months after hospitalization increased from 31.0% in 19941995 to 44.3% in 19992000. Adjusted one-year mortality was lower in seniors with prescriptions for beta-blockers (18.2%; 95% confidence interval [CI] 14.2 to 22.2), ACE inhibitors/RBs (22.3%; 95% CI 20.9 to 23.7), or both (16.6%; 95% CI 13.3 to 20.0), compared with those with no prescriptions (29.9%; 95% CI 28.8 to 31.0). Absolute adjusted risk reduction comparing no prescription with prescription of both beta-blockers or ACE inhibitors/RBs was 13.3% for a relative adjusted risk reduction of 44%.
CONCLUSIONS: This study of incident CHF hospitalizations among seniors demonstrates an association between decreased mortality and the use of beta-blockers, ACE inhibitors/RBs, or combination of both. The effectiveness of beta-blockers and ACE inhibitors/RBs for CHF should be more broadly tested in clinical trials that recruit older patients and those with diastolic dysfunction.
