Characteristics, clinical management and outcomes of patients with acute myocardial infarction enrolled or not enrolled in a quality registry

Patients non-enrolled in SWEDEHEART received less evidence-based care and had worse short- and long-term outcomes. This study identifies a non-negligible population in need of better care and provides support for the value of structured care models in improving patient outcomes through closer monitoring and better treatment.
Study context
- Population
- Patients hospitalised for a first or recurrent myocardial infarction between 2006 and 2021 in the region of Stockholm, Sweden, linked to the SWEDEHEART quality registry
- Participants
- 47,342 hospitalisations
- Comparison
- Non-enrolled vs. enrolled patients
- Non-enrolledn = 6,113
- Outcome
- Initiation of aspirin

Admission characteristics
- Non-enrolled participants were older, had more chronic kidney disease and other comorbidities
Invasive procedures
- Non-enrolled underwent fewer coronary angiographies and fewer coronary interventions
Adherence to treatments
- Non-enrolled less likely to adhere to treatments, in part explained by their comorbid profile
