Abstract

CONTEXT:

Statins in primary prevention before 75 years old reduce cardiovascular events from 20 to 30% and mortality from 10% with acceptable side effects. We investigated whether these results persisted for patients aged 75 and older taking statin.

METHOD:

Methodic review of large randomized clinical trials and meta-analyzes that included patients 75 years and older treated with statins in primary prevention.

RESULTS:

Since the 1990s, a score of randomized controlled trials studying statins versus placebo in primary prevention were published and studied in meta-analyses. Exclusion criteria, including persons older than 70 years, are often restrictive. The impact on all-cause mortality in the four main studies and meta-analyses in over 75 years has not been demonstrated. On the other hand, a recent meta-analyses of observational studies including subjects between 70 and 89 years treated with statins found that low total cholesterol was associated with a moderate decrease in cardiovascular mortality, with no decrease in all-cause mortality. Moreover, in a common context of comorbidities in this age group, statins may be responsible for many adverse effects, drug interactions and impaired quality of life.

CONCLUSION:

Given the lack of formal evidence of effectiveness in terms of all-cause mortality and a high level of adverse effects, the benefit/risk of primary prevention with statins is not established in the elderly. The economic weight of statin prescriptions and their possible impact on quality of life justify an economic analysis of discontinuing statin therapy for people 75 years and older.
