title: Treadmill test is limited in elderly patients with peripheral arterial disease.
abstract: BACKGROUND
  To describe the applicability and the performance of the treadmill test in elderly patients with peripheral arterial disease (PAD) and without PAD (non-PAD).
  
  
  METHODS
  Fifty consecutive PAD and non-PAD elderly patients performed a progressive treadmill test. The proportion of patients who were unable to perform the test and the maximal walking distance were obtained.
  
  
  RESULTS
  The proportion of patients who were unable to perform the treadmill test was similar between PAD (16.6 %) and non-PAD patients (12.5 %), P = .57. Maximal walking time for patients who performed the treadmill test was not different between PAD (232 +/- 218 s) and non-PAD patients (308 +/- 289 s), P = .37.
  
  
  CONCLUSIONS
  The treadmill test is limited in almost 20 % of elderly patients with PAD and non-PAD. These results highlight the need for other forms of exercise stress tests in order to assess the peripheral limitation of patients with PAD.
