Authors' conclusion

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.

Initiation of statins · less likely to initiate0.59 (CI 0.56–0.61)

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
