Key result
Targeted PAD case-finding with resting ABI is favored over universal screening in hypertension care.
Why the study?
Peripheral artery disease is common in people with hypertension, but it is often underrecognized because symptoms are frequently absent or atypical and access to physiologic testing is uneven.
This narrative review outlines a risk-stratified, treatment-linked diagnostic pathway for detecting peripheral artery disease in patients with hypertension while distinguishing targeted case-finding from unproven universal screening.
BACKGROUND: Peripheral artery disease (PAD) is common but often underrecognized in people with hypertension because symptoms are frequently absent or atypical and access to physiologic testing is uneven. This narrative review examines how hypertension care can support risk-stratified PAD recognition while keeping targeted case-finding distinct from universal screening. METHODS: We conducted a structured narrative review of PubMed/MEDLINE from inception through 31 July 2026, supplemented by citation searching and review of major US and European guidelines and relevant US policy and coverage sources. Evidence was interpreted according to the question it could answer: association/prognosis, diagnostic accuracy, treatment effect, implementation, or policy status. RESULTS: Hypertension and PAD share age-related, metabolic, renal, and tobacco-related determinants, while pressure-related vascular injury provides biological plausibility for their association. Resting ankle-brachial index (ABI) is the initial physiologic test for appropriately selected people; toe-brachial index with waveforms is preferred for noncompressible ankle arteries, exercise ABI for persistent exertional symptoms despite normal or borderline resting values, and duplex ultrasound when anatomic definition will change management. Guideline-supported risk-based testing differs from universal screening of unselected asymptomatic adults, for which outcome benefit remains unproven. Detection is clinically meaningful only when linked to appropriate prevention, symptom management, foot protection, and referral. CONCLUSION: This narrative review supports a risk-stratified, treatment-linked approach to PAD recognition in hypertension care, but the proposed case-finding pathway itself has not been proven to improve clinical outcomes. Pragmatic trials of the complete care pathway are needed.

Li et al. (2026) conducted a review in Peripheral artery disease (PAD) in people with hypertension. Risk-stratified PAD case-finding (resting ankle-brachial index, toe-brachial index, exercise ABI, duplex ultrasound) vs. Universal screening of unselected asymptomatic adults was evaluated. Risk-stratified, treatment-linked PAD case-finding using resting ABI in hypertension care is supported over universal screening, though outcome benefit of the pathway remains unproven.
