Introduction and methods

The use of statin therapy in primary prevention in the elderly is topic of debate, and little evidence is available for or against its benefit [1-4]. Both the European guidelines on the management of dyslipidemias and the one on CV disease prevention in clinical practice, give no recommendation for or against statin use for primary prevention in individuals over the age of 75 years [5,6]. The American 2018 ACC/AHA guidelines only recommend a shared decision-making process between clinician and patient and regular reassessment. The ACC/AHA guidelines do mention that if CAC score is 0, the likelihood of benefits does not outweigh the risks in older adults [7].

An outstanding question for clinical practice is whether existing statin therapy can be stopped in older people without a history of CV disease. This study therefore aimed to assess the effect of statin discontinuation on CV outcomes in persons who turned 75 years old in 2012-2014, who were previously adherent to statin therapy (medication possession ratio [MPR] >80%) for at least two years with no history of CV disease. This retrospective study used French healthcare databases. Individuals with a diagnosis of CV disease or a related in-hospital procedure in the previous 2 years and patients taking combined use of CV preventive medication or long-term treatment with an antiplatelet agent other than aspirin, were excluded. Statin therapy was considered to be discontinued if a person presented three consecutive months without exposure. The outcome of interest was hospital admission for a CVD event. 102.173 patients were included and mean follow-up was 2.4 years (max: 4 years). The total follow-up of 3.067.730 months included 176.373 (5.7%) patient-months after statin discontinuation.

Main results

In 75-year-olds taking statin for primary prevention, discontinuation was associated with higher CV risk


In a population-based primary prevention cohort of 75-year-old individuals who were previously adherent to statin therapy for at least 2 years, discontinuation of statins was associated with a higher risk of admission for a CV event. The association with admission was stronger for coronary events than for cerebrovascular events. Considering the observational nature of these data, the findings should be confirmed in randomized studies.
