New Horizons in Peripheral Artery Disease

Area of Science:

• Vascular Surgery
• Geriatric Medicine
• Cardiology

Background:

• Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis, affecting over 10% of individuals aged 65+.
• Chronic limb-threatening ischemia (CLTI), the advanced stage of PAD, presents with severe symptoms like rest pain and tissue loss.
• PAD and CLTI management guidelines are evolving due to increasing diabetes prevalence and new research.

Purpose of the Study:

• To summarize recent updates in the definition, diagnosis, and staging of PAD and CLTI.
• To highlight advancements in optimal medical therapy and revascularization strategies.
• To emphasize the growing recognition of complex patient factors in CLTI and the role of geriatric input.

Main Methods:

• Review of updated clinical guidelines for PAD and CLTI.
• Analysis of recent randomized trials comparing revascularization approaches (bypass-first vs. endovascular-first).
• Inclusion of emerging evidence on managing complex CLTI patients, including those with frailty and cognitive impairment.

Main Results:

• Updated guidelines incorporate changing disease patterns and increased diabetes prevalence.
• Low-dose anticoagulant plus aspirin is recommended for specific patient groups.
• Minimally invasive endovascular techniques offer more options for complex infra-inguinal disease.
• CLTI patients often present with frailty, cognitive impairment, multi-morbidity, and polypharmacy, impacting survival despite revascularization advances.

Conclusions:

• Shared decision-making and conservative management are crucial for older CLTI patients.
• Specialist geriatric team input shows emerging benefits in perioperative management.
• UK guidelines now recommend frailty, cognitive impairment, and delirium screening, alongside geriatric support for vascular surgery patients.
