Insights
Use of four key cardiac medications for acute myocardial infarction increased significantly from 1995 to 2005. This trend was observed across all age groups and genders, indicating improved evidence-based therapy adoption.
Area of Science:
- Cardiology
- Public Health
- Health Services Research
Background:
- Guidelines recommend four cardiac medications for acute myocardial infarction (AMI) management.
- Limited population-based data exist on contemporary use of these therapies.
- This study examines trends in medication use during AMI hospitalizations.
Purpose of the Study:
- To describe contemporary use of four key cardiac medications during AMI hospitalization.
- To analyze trends in medication use by age, gender, and hospitalization period.
- To assess changes in the adoption of evidence-based therapies for AMI.
Main Methods:
- Retrospective analysis of 6334 patients hospitalized with AMI.
- Data collected from 11 hospitals in the Worcester, Mass, metropolitan area.
- Study periods spanned six annual intervals between 1995 and 2005.
Main Results:
- Significant increases in the use of all four cardiac medications were observed between 1995 and 2005.
- Medication use increased across all age strata for both men and women.
- Specific increases noted: men (4%-47%), women (2%-42%) overall; age groups showed similar upward trends.
Conclusions:
- Marked increases in evidence-based therapies for AMI patients over time.
- Educational initiatives to enhance use of effective cardiac therapies are supported.
- Further research needed to identify and address suboptimally treated patient groups.
Background:
Guidelines for the management of patients with acute myocardial infarction recommend the routine use of 4 effective cardiac medications: angiotensin-converting enzyme inhibitors, aspirin, beta-blockers, and lipid-lowering agents. Limited data are available, however, about the contemporary and changing use of these therapies, particularly from a population-based perspective. The study describes differences in the use of these medications during hospitalization for acute myocardial infarction according to age, gender, and period of hospitalization.
Methods:
The study population consisted of 6334 women and men treated at 11 hospitals in the Worcester, Mass, metropolitan area for acute myocardial infarction in 6 annual periods between 1995 and 2005.
Results:
Increases in the use of all 4 cardiac medications during hospitalization for acute myocardial infarction were noted between 1995 and 2005 for all men and in those of different age strata: less than 65 years (4%-47%); 65 to 74 years (4%-46%); 75 to 84 years (2%-48%); and more than 85 years (0%-23%). Increases in the use of all 4 cardiac medications also were observed in all women and in those of all ages over time (2%-42%); 65 to 74 years (8%-47%); 75 to 84 years (1%-44%); and more than 85 years (1%-44%).
Conclusion:
The present results suggest marked increases over time in the use of evidence-based therapies in patients hospitalized with acute myocardial infarction. Educational efforts to augment the use of these effective cardiac therapies, as well as attempts to identify suboptimally treated groups, remain warranted.
