There is increasing research interest in cholesterol-lowering therapy in older patients. The newer lipid-lowering agents (the proprotein convertase subtilisin/kexin type 9 [PCSK9] inhibitors evolocumab and alirocumab; the PCSK9 synthesis inhibitor inclisiran, and the adenosine triphosphate-citrate lyase inhibitor bempedoic acid) might also provide more options for the future treatment of older patients. Data analyses of the phase III outcome trials of the PCSK9 inhibitors suggest that their clinical benefits are maintained at older ages and that there is no increased relative risk of adverse events in older patients; however, data from patients aged ≥ 75 years and particularly aged ≥ 85 years are limited, and the trials did not collect information on the frailty status of patients. Frailty is a predictor of adverse outcomes, including mortality, and might help guide therapy decisions. To date, no outcome data are available for cardiovascular endpoints for the low-density lipoprotein cholesterol-lowering drugs inclisiran and bempedoic acid. Except for the risk of gout and tendon rupture with bempedoic acid, which remains to be further characterized in larger populations, the safety profile of the novel lipid-lowering agents in older patients seems favorable. The newer lipid-lowering agents could be added to other lipid-lowering medication or used as an alternative treatment in older patients with documented statin intolerance (as is already recommended in guidelines for the PCSK9 inhibitors), such as myopathy. Especially in older patients needing high-intensity therapy despite polypharmacy or certain comedications, the absence of clinically relevant drug-drug interactions with the PCSK9 inhibitors and inclisiran might be an advantage.
