Role of Statin Therapy in Primary Prevention of Cardiovascular Disease in Elderly Patients

Purpose of ReviewHypercholesterolemia and statin treatment are nowadays common among people older than 75years, but clinical heterogeneity in this increasing age group is wide, and treatment decisions may differ from those in younger patients. Aim is to discuss the presentation, modifying factors, and treatment decisions of hypercholesterolemia (usually with statins) in older persons and focusing on primary prevention.Recent FindingsThere are no randomized controlled trials in persons older than 80years at baseline. Randomized controlled trial findings in younger patients and 75+ subgroups and in observational studies support treatment in secondary prevention of atherosclerotic cardiovascular disease (ASCVD), but trial evidence in primary prevention is less clear. Available data do not imply specific harms in older patients, and, therefore, also, judicious primary prevention is possible. However, persons older than 75years are biologically a very heterogeneous group with frequent frailty, comorbid conditions, and multiple concomitant drugs. All these, as well as personal preferences, must be taken into account in treatment decisions.SummaryStatin treatment is only one way to prevent ASCVD in older people. Treatment of hypercholesterolemia should be started far before 75-80years, and there is no need to discontinue statin treatment due to chronological age alone. After 75years, treatment should be started in patients with ASCVD and judiciously in primary prevention. Like all prevention, statin treatment should be discontinued when palliative treatment is started. Ongoing and planned trials in 70+ individuals will give more information about primary prevention in older persons.
