Use of statins and beta-blockers after acute myocardial infarction according to income and education
Key result
High income linked to ~27% higher statin initiation post-AMI and fewer treatment breaks versus low income.
- HR 1.27
- 95% CI 1.19-1.35
- n=30,078
Why the study?
Does income level affect the initiation and persistency of statin and beta-blocker treatment in patients surviving their first AMI?
Population
30,078 patients aged 30-74 years surviving first hospitalisation for acute myocardial infarction in Denmark…

Implication
Income disparities in post-AMI statin initiation warrant monitoring; leaves open effective equity interventions in secondary prevention.

Population
30,078 patients aged 30-74 years surviving their first hospitalization for acute myocardial infarction in Denmark between 1995 and 2001.

Exposure
High or medium income
C
Comparator
Low income
O
Outcome
Initiation of statin or beta-blocker treatment (out-patient claim of prescriptions within 6 months of discharge) and refill persistency (first break in treatment lasting at least 90 days, and re-initiation of treatment after a break)
Main Result
Hazard Ratio: 1.27 (95% CI 1.19–1.35)
Lower income is associated with decreased initiation and worse long-term persistency of statin therapy post-AMI, highlighting socioeconomic disparities in secondary prevention.

Rasmussen et al. (2007) conducted a cohort in acute myocardial infarction (n=30,078). High income vs. Low income was evaluated on Initiation of statin treatment (HR 1.27, 95% CI 1.19-1.35). High income was associated with increased initiation of statin treatment post-AMI compared with low income (HR 1.27; 95% CI 1.19-1.35) and a lower risk of treatment break.
