title: Reprinted article "Exercise training versus angioplasty for stable claudication. Long and medium term results of a prospective, randomised trial".
abstract: OBJECTIVE
  To compare percutaneous transluminal angioplsty (PTA) against exercise training in the treatment of stable claudication.
  
  
  METHODS
  Prospective, randomised trial.
  
  
  METHODS
  Fifty-six patients with unilateral, stable, lower limb claudication assessed prior to randomisation, at 3 monthly intervals for 15 months, and at approximately 6 years follow-up. Thirty-seven patients were available for long term review.
  
  
  METHODS
  Ankle/brachial pressure index (ABPI), treadmill claudication and maximum walking distances, percentage fall in ankle systolic pressure after exercise.
  
  
  RESULTS
  Significant increases were seen in ABPI in the patients treated with PTA at all assessment to 15 months. However in terms of improved walking performance, the most significant changes in claudication and maximum walking distance were seen in the exercise training group. At long term follow-up, there was no significant difference between the groups. Subgroup analysis by angiographic site of disease showed greater functional improvement in those patients with disease confined to the superficial femoral artery treated by exercise training. The overall prognosis for the whole group of patients was benign, with only two (4%) undergoing amputation.
  
  
  CONCLUSIONS
  Exercise training confers a greater improvement in claudication and maximum walking distance than PTA, especially in patients with disease confined to the superficial femoral artery.
