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

A population-based cohort study using a record-linkage database in Tayside, Scotland, assessing adherence and outcomes over 10 years.

Potential Biases

Potential bias from unmeasured confounders related to lifestyle and adherence behaviors.

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.
