hypercholesterolemia

The risk of atherosclerotic cardiovascular disease increases with advancing age. Elevated LDL-cholesterol and non-HDL-cholesterol levels remain predictive of incident atherosclerotic cardiovascular events among individuals older than 75 years. Risk prediction among older individuals is less certain because most current risk calculators lack specificity in those older than 75 years and do not adjust for co-morbidities, functional status, frailty, and cognition which significantly impact prognosis in this age group. Data on the benefits and risks of lowering LDL-cholesterol with statins in older patients without atherosclerotic cardiovascular disease are also limited since most primary prevention trials have included mostly younger patients. Available data suggest that statin therapy in older primary prevention patients may reduce atherosclerotic cardiovascular events and that benefits from lipid-lowering with statins outweigh potential risks such as statin-associated muscle symptoms and incident Type 2 diabetes mellitus. While some evidence suggests the possibility that statins may be associated with incident cognitive impairment in older adults, a preponderance of literature indicates neutral or even protective statin-related cognitive effects. Shared decision-making which is recommended for all patients when considering statin therapy is particularly important in older patients. Randomized clinical trial data evaluating the use of non-statin lipid-lowering therapy in older patients are sparse. Deprescribing of lipid-lowering agents may be appropriate for select patients older than 75 years with life-limiting diseases. Finally, a patient-centered approach should be taken when considering primary prevention strategies for older adults.
