title: Clinical importance of change in physical activity after endovascular treatment combined with exercise training in patients with peripheral arterial disease.
abstract: We aimed to investigate the characteristics of changes in amount of physical activity of patients with peripheral arterial disease (PAD) before/after endovascular treatment (EVT) combined with exercise training. Twenty-two patients with peripheral arterial disease at stage-II of the Fontaine classification who received EVT combined with exercise training were included in this study. A tri-axial accelerometer was used to record physical activity every day from the day before surgery to 3 months after discharge from hospital. The mean number of walking steps before surgery was 2664 steps (611 steps-5404 steps), whereas those after surgery was 3393 (567 steps-7578 steps). Ankle Brachial Index (from 0.69 to 1.03; p < 0.001), maximum walking distance (from 728.2 to 1271.8 m; p < 0.05) and Vascu-QOL (from 98.9 to 137.9; p < 0.01) showed improvement between before and after surgery. Physical activity of patients with PAD was still low at 3 months after surgery even though walking ability, QOL, and self-efficacy were improved after EVT combined with exercise training. Among the 22 patients, the number of walking steps increased in 17 of them and decreased in 5 of them. Compared with the patients in the increased-steps group, those in the decreased-steps group were significantly older (p < 0.05), and had a significantly higher cardiovascular event rate within the first 3 months after surgery (p < 0.05). These results suggested that, not only the improvement of walking ability, but increase in physical activity after EVT combined with exercise training is also important for short-term prognosis.
