Care Plan for High Cholesterol in Patients Over 75 Years of Age
For patients over 75 years of age with hyperlipidemia, statin therapy should be continued if already on treatment, but for primary prevention, initiation of statin therapy should be based on a patient-centered approach considering overall cardiovascular risk, life expectancy, and potential benefits versus risks.
Assessment and Risk Stratification
- For patients >75 years with clinical atherosclerotic cardiovascular disease (ASCVD), it is reasonable to continue moderate or high-intensity statin therapy after evaluating potential benefits, adverse effects, drug interactions, frailty, and patient preferences 1
- For primary prevention in adults >75 years without established ASCVD, recommendations for initiating statin therapy are weaker (Class IIb) due to limited and conflicting evidence 1
- The heterogeneity in physical and functional health increases with age, leading to greater variability in cardiovascular risk and life expectancy than in younger adults 2
Treatment Recommendations
Secondary Prevention (Established ASCVD)
- In patients >75 years with clinical ASCVD who are tolerating statin therapy, it is reasonable to continue the current regimen 1
- For those not currently on statin therapy but with established ASCVD, it is reasonable to initiate moderate-intensity statin therapy after evaluating potential benefits, adverse effects, drug interactions, frailty, and patient preferences 1
- High-intensity statin therapy may be considered in select patients with recent ASCVD events and low risk of adverse effects 1
Primary Prevention (No Established ASCVD)
- For adults >75 years without established ASCVD, the decision to initiate statin therapy should shift from a strictly 10-year cardiovascular risk-driven approach to a patient-centered approach considering life expectancy and overall health status 2
- Consider moderate-intensity statin therapy in patients with diabetes mellitus and additional cardiovascular risk factors 1
- For those with very high LDL-C levels (≥190 mg/dL), statin therapy may be considered after careful evaluation of risk-benefit ratio 1
Lifestyle Modifications
- Regardless of pharmacological therapy decisions, lifestyle modifications should be recommended for all patients 1:
- Dietary changes focusing on reduction of saturated fat, trans fat, and cholesterol intake
- Increased consumption of omega-3 fatty acids, viscous fiber, and plant stanols/sterols
- Weight management if indicated
- Regular physical activity appropriate for age and functional status
- For patients with elevated triglycerides (≥150 mg/dL), intensify lifestyle therapy and optimize management of secondary factors 1
Special Considerations for Older Adults
- Recognize that the predictive value of elevated cholesterol for cardiovascular events diminishes with advancing age, particularly after 75 years 3
- In very elderly patients, some evidence suggests high total cholesterol may be associated with longevity 3
- Assess for polypharmacy and potential drug interactions before initiating or continuing lipid-lowering therapy 1
- Evaluate renal function, as some statins require dose adjustment with decreased renal function 1
- Monitor for statin-associated side effects, which may be more common or problematic in older adults 1
Monitoring and Follow-up
- Regular lipid profile monitoring (every 1-2 years) is reasonable for ongoing assessment 1
- Evaluate for medication adherence, side effects, and changes in overall health status at follow-up visits 1
- Reassess cardiovascular risk periodically, as risk factors may change with advancing age 1
- Consider deprescribing lipid-lowering therapy in patients with limited life expectancy or when potential harms outweigh benefits 2
Common Pitfalls and Caveats
- Avoid initiating statin therapy in patients on dialysis, as evidence does not support benefit in this population 1
- Traditional risk calculators tend to overestimate cardiovascular risk in older adults; consider using age-specific risk assessment tools when available 2
- The benefit-to-risk ratio of statin therapy decreases with advancing age and increasing frailty 1
- Recognize that goals of care may shift with advancing age from preventing long-term cardiovascular events to maintaining quality of life and minimizing medication burden 2
