Hypothesis
Does adherence to statin and aspirin treatments affect the recurrence of cardiovascular disease and all-cause mortality in patients with established cardiovascular disease?
Conclusion
Good adherence to both statins and aspirin treatment is associated with lower risks of recurrence of cardiovascular disease and all-cause mortality.
Supporting Evidence
- Patients taking both aspirin and statins had better adherence than those on single drug treatments.
- Good adherence was associated with better outcomes in patients taking both treatments.
- Adherence to statins predicted a good outcome, while adherence to aspirin did not.
Takeaway
Taking your heart medicine regularly helps you stay healthy and avoid getting sick again. If you forget to take it, you might not feel as good.
Methodology

Limitations
The study lacks information on lifestyle factors and may underestimate adherence due to reliance on prescription dispensing data.
Participant Demographics
Patients with established cardiovascular disease, average age 67.5 years, 46% women.
