Role of Age (≥70 years)
High Risk vs Very High Risk
Clinical constellation | ESC/EAS risk category |
Carotid plaques without symptoms | High risk |
Carotid plaques + additional risk factors (e.g., diabetes, CKD, smoking) | Very high risk |
Carotid plaques + prior stroke/TIA | Very high risk (secondary prevention) |
Therapeutic Consequences
LDL-C Targets According to ESC/EAS
Risk category | LDL-C target |
High risk | <70 mg/dL and ≥50% reduction |
Very high risk | <55 mg/dL and ≥50% reduction |
Statin therapy is indicated even at advanced age, provided there are no contraindications.
Important Clarification Regarding Age
Age ≥75–80 years is not a contraindication to statin therapy.
The ESC/EAS emphasize:
Core Message
A patient >70 years with carotid plaques is at least high risk according to ESC/EAS; with additional risk factors (CAD, hypertension, smoking, etc.), the patient is very high risk.
This results in a clear indication for LDL-lowering therapy with a high-potency statin at plaque-stabilizing doses
(e.g., rosuvastatin ≥20 mg, atorvastatin ≥40 mg).
ESC/EAS guidelines do not recommend age-based discontinuation, but rather an individualized, target-oriented approach.
Monitoring & Re-evaluation
Risk classification is not primarily age-based, but driven by evidence of atherosclerotic vascular disease.
Mach F, Baigent C, Catapano AL, et al. 2019 ESC/EAS Guidelines for the management of dyslipidaemias: lipid modification to reduce cardiovascular risk. European Heart Journal. 2020;41(1):111–188. doi:10.1093/eurheartj/ehz455.
Thus, they fulfill a high-risk criterion per se.
Plaque / “Carotid Atherosclerosis” (Ultrasound, Vessel Wall Finding)
In population-based ultrasound studies, prevalence in the 75–84-year age group is approximately 75–85%:
(Definition: carotid atherosclerosis/plaques on B-mode ultrasound)
Practical implication:
In individuals >75 years, carotid plaques are the rule rather than the exception when actively assessed.
Stenosis
Prevalence is much lower, as most plaques do not cause high-grade luminal narrowing:
A plaque / “carotid atherosclerosis” detected on ultrasound (vessel wall finding) is an independent marker of systemic atherosclerosis and is considered a risk factor for coronary artery disease, myocardial infarction, and stroke.
Clinically, it justifies a higher cardiovascular risk classification, even if not explicitly included in many risk scores.
A plaque indicates that the patient has manifest atherosclerosis, even if still asymptomatic.
The finding is not only locally relevant but systemically prognostic.
Consequences for Risk Stratification
Formally (Risk Scores)
Clinically (Decisive)
A documented carotid plaque is considered a “risk modifier” and typically results in:
Many guidelines essentially state:
Evidence of subclinical atherosclerosis = higher true risk than numerically estimated
Practical Consequences (Typical Scenario)
A patient with:
is often classified as having:
with implications for:
