Conservative management can improve outcomes for intermittent claudication patients. Monitoring ankle-brachial index (ABI) helps predict clinical outcomes and the need for vascular surgery.

Area of Science:

  • Vascular Medicine
  • Clinical Outcomes Research

Background:

  • Intermittent claudication is a common symptom of peripheral artery disease.
  • Understanding predictors of disease progression is crucial for patient management.

Purpose of the Study:

  • To analyze parameters predicting clinical outcomes in intermittent claudication.
  • To evaluate the effectiveness of conservative management.

Main Methods:

  • Retrospective review of 460 patients with intermittent claudication.
  • Average follow-up of 4.1 years with conservative management.
  • Analysis of ankle-brachial index (ABI) at initial and follow-up evaluations.

Main Results:

  • 44.1% of patients experienced disease deterioration, requiring vascular surgery.

  • Higher initial ABI (>0.7) and stable ABI during follow-up increased favorable outcome chances.
  • Lower initial ABI (<0.5) and significant ABI decrease predicted increased risk for vascular surgery.

    • Conclusions:

    • Ankle-brachial index (ABI) effectively predicts intermittent claudication outcomes.
    • Conservative management, including lifestyle changes, can modify disease progression.
    • Systemic vascular health influences lower limb arterial disease progression.
