Asymptomatic peripheral artery disease: Silent but deadly

Area of Science:

• Vascular Medicine
• Cardiovascular Disease
• Atherosclerosis Research

Background:

• Peripheral Artery Disease (PAD) is a manifestation of atherosclerosis, leading to reduced limb perfusion and metabolic dysfunction.
• The asymptomatic PAD phenotype, while increasingly recognized, lacks defined prevalence due to absent universal screening protocols.
• Patients with asymptomatic PAD share comparable morbidity and mortality risks with those experiencing symptomatic PAD (e.g., claudication).

Purpose of the Study:

• To highlight the clinical gap in understanding and treating asymptomatic PAD.
• To advocate for the investigation of existing pharmacotherapies in the asymptomatic PAD population.
• To emphasize the need for widespread screening of asymptomatic PAD to mitigate adverse outcomes.

Main Methods:

• This study is a review and position paper, analyzing existing literature on PAD phenotypes and therapeutic approaches.
• It examines current pharmacotherapies used in PAD without stratifying for symptom status.
• The paper calls for future clinical investigations tailored to asymptomatic PAD patients.

Main Results:

• The prevalence of asymptomatic PAD remains unknown due to a lack of standardized screening guidelines.
• Existing PAD pharmacotherapies have not been specifically evaluated for efficacy in asymptomatic individuals.
• Patients with asymptomatic PAD exhibit a similar risk profile for morbidity and mortality as symptomatic PAD patients.

Conclusions:

• Further research into existing therapies for asymptomatic PAD is essential to reduce associated morbidity and mortality.
• Implementing widespread screening for asymptomatic PAD is critical for early detection and intervention.
• Addressing the asymptomatic PAD population represents a significant opportunity to improve cardiovascular outcomes.
