Elevated prevalence rates are observed in specific high-risk groups, such as older adults with isolated systolic hypertension (25%), maintenance hemodialysis patients (9.4%), and those with heterozygous familial hypercholesterolemia (4.2% for ≥50% stenosis). Conversely, the prevalence is low in certain populations like kidney transplant candidates (1.47% for >70% stenosis) and patients undergoing isolated heart valve surgery (2.25% for…","trust_label":"machine_generated_human_reviewed","editorial_verification":{"status":"human_reviewed","trust_label":"machine_generated_human_reviewed","method":"World ID proof-of-human editorial account","scope":["clinical_integrity","reference_quality","scientific_coherence"],"verification_note":"This Evidence Object is machine-generated and human-reviewed.
