Abstract

We evaluated the outcome of multimodal supervised exercise training (SET) on walking performances and different hemodynamic parameters (ankle/toe-brachial index [ABI/TBI], and transcutaneous oxygen pressure [TcPO2]) in patients with symptomatic lower extremity peripheral artery disease (PAD). Whether hemodynamic parameters predict walking performances at baseline and following SET was also investigated. Fontaine stage II PAD's patients following a 3-month SET were retrospectively included. Hemodynamic parameters and walking performances (pain-free [PFWD], maximal [MWD], and 6-minute [6MWD] walking distance) were measured in each patient. Eighty-five symptomatic PAD patients were included. Following SET, PFWD, MWD, and 6MWD significantly increased (+142%, +94%, +14%; respectively; P ≤ .001). Toe-brachial index significantly increased (MD: 0.04 ± 0.01; P = .02), whereas ABI and TcPO2 did not change significantly. At baseline, patients with higher TBI and TcPO2 performed significantly better (PFWD: β = 0.25, P = .01 for TBI; PFWD: β = 0.30, P = .005, and MWD: β = 0.22, P = .04, for TcPO2). No significant relationship was observed at baseline between ABI and walking performances. Baseline values of hemodynamic parameters did not si...Continue Reading
