Context. - Despite the importance of bêta-blockers for secondary prevention after acute myocardial infarction (AMI), several studies have suggested that they are substantially underutilized, particularly in older patients.
- To describe the contemporary national pattern of bêta-blocker prescription at hospital discharge among patients aged 65 years or older with an AMI, to identify the most important predictors of the prescribed use of bêta-blockers at discharge, and to determine the independent association between bêta-blockers at discharge and mortality in clinical practice.
- Retrospective cohort study using data created from medical charts and administrative files.
- Acute care nongovernmental hospitals in the United States.
- National cohort of 115015 eligible patients aged 65 years or older who survived hospitalization with a confirmed AMI in 1994 or 1995.
- bêta-Blocker as a discharge medication and mortality in the year after discharge.
- Among the 45 308 patients without contraindications to bêta-blockers, 22 665 (50.0%) had a bêta-blocker as a discharge medication.
There was significant variation by state, ranging from 30.3% to 77.1%. Of the 36 795 patients who were not receiving bêta-blocker therapy on admission, 16 006 (43.5%) had therapy initiated on or before discharge. (...)
