CAVEATS
Retrospective cohort design leaves cause and effect equivocal
Even though the first study was large (with more than 46,000 patients) and the median follow-up was 5.6 years, it was a retrospective cohort study. While there is clearly an association between statin therapy and reduced ASCVD and all-cause mortality in patients with diabetes ages 75 to 84 years, cause and effect cannot be unequivocally stated. However, the meta-analysis, which included RCTs, confirms the benefit of statins in secondary prevention for older patients.
The cohort study did not look at adverse effects from statin therapy in this age group, but the data from the 2019 meta-analysis did not reveal any significant risk of myopathy.
CHALLENGES TO IMPLEMENTATION
Guidelines are lacking and discontinuing meds requires discussion
The lack of supporting guidelines to treat this age group with statins remains the largest barrier to implementation. Many patients may already be taking a statin, so a discussion about discontinuing medication will need to be initiated.
