Peripheral arterial disease (PAD) significantly increases mortality risk and is often underdiagnosed. Early diagnosis via ankle-brachial index and risk factor management are crucial for patient outcomes.

Area of Science:

  • Vascular Medicine
  • Cardiovascular Disease
  • Atherosclerosis Research

Background:

  • Peripheral arterial disease (PAD) is a common manifestation of systemic atherosclerosis, leading to lower extremity arterial occlusion.
  • Patients with PAD face significantly elevated risks of all-cause mortality (3x) and coronary heart disease death (6x) compared to the general population.
  • PAD remains underdiagnosed and undertreated despite its severe prognostic implications.

Purpose of the Study:

  • To highlight the diagnostic importance and prognostic value of the ankle-brachial index (ABI) in peripheral arterial disease.
  • To emphasize the critical need for aggressive management of PAD, including risk factor modification and secondary prevention.

Main Methods:

  • Review of diagnostic approaches for PAD, emphasizing clinical history, physical examination, and noninvasive testing.

  • Focus on the ankle-brachial index (ABI) as a key tool for diagnosis, risk stratification, and monitoring disease progression.

    • Main Results:

    • Clinical diagnosis of PAD has limitations in sensitivity and specificity.
    • The ankle-brachial index (ABI) is a reliable, easily performed test that correlates with PAD severity and functional status.
    • ABI is a strong predictor of cardiovascular and cerebrovascular mortality.

    Conclusions:

    • Accurate diagnosis of PAD using tools like the ABI is essential for patient risk stratification.
    • Comprehensive management of PAD, including risk factor modification, symptomatic treatment, and antiplatelet therapy, is critical for secondary prevention.
