Summary

Angioplasty shows higher symptomatic success rates than exercise therapy for intermittent claudication at 6 months, but carries a risk of major complications. Further research is needed for a definitive comparison.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Rehabilitation Medicine

Background:

  • Intermittent claudication significantly impacts patient quality of life.
  • Exercise therapy and angioplasty are primary treatment options for intermittent claudication.
  • Evidence comparing the long-term efficacy and safety of these treatments is limited.

Purpose of the Study:

  • To compare the clinical outcomes of exercise therapy versus angioplasty in patients with intermittent claudication.
  • To evaluate symptomatic success rates and complication profiles of both treatment modalities.

Main Methods:

  • A summation analysis of published studies was conducted.
  • Literature search of MEDLINE and PUBMED (1966-1999) identified relevant angioplasty and exercise therapy studies.

  • Included studies reported outcomes for intermittent claudication patients at a minimum of 6 months follow-up.

    • Main Results:

    • Angioplasty (2071 patients) demonstrated a mean symptomatic success rate of 76.6%, with a 2.7% major complication rate.
    • Exercise therapy (294 patients) showed a mean symptomatic success rate of 38.4% and a 189.7% improvement in walking distance at 6 months.
    • Direct comparison was limited by heterogeneity in study design, patient numbers, and outcome assessment.

    Conclusions:

    • Angioplasty appears more effective than exercise therapy for symptom relief at 6 months, despite a small risk of major complications.
    • Significant disparities in study methodologies hinder definitive conclusions.
    • A validated, disease-specific instrument is required for future randomized controlled trials to accurately compare these therapies.
