Study | Population screened | Treatment arms | Functional outcome tools | PROMs tools | Follow-up period | Changes |
---|---|---|---|---|---|---|
Murphy (2015)10 (CLEVER study) | 111 patients with aortoiliac PAD, multicenter | Optimal medical care alone; both SET and medical care; or both revascularization and medical care | Treadmill-based walking, ABI | SF-12, WIQ, PAQ | 18 months | Combination arms had greater improvements in disease-specific PROMs; SET cohort had greater improvements in PAQ scores compared to revascularization cohort |
Gray (2015)28 (STROLL study) | 250 subjects with de novo or restenotic lesions of superficial femoral artery, multicenter | One or more SMART® bare-metal stents | Rutherford/Becker classification, resting or exercise ABI, angiographic studies | PAQ, WIQ, EQ-5D, SF-12 | 3 years | PAQ summary scores showed significant health status gains at 1 month, with more than 85% of the gain maintained during a 3-year period |
Mustapha (2019)43 (LIBERTY 360° study) | 1200 patients with claudication and CLI, multicenter | Treatment with an FDA-approved peripheral endovascular device intervention | Rutherford classification, angiography imaging, duplex ultrasonography | VascuQoL, EQ-5D | 12 months, up to 5 years | VascuQoL scores improved significantly from baseline to 30 days and persisted at 12 months across all domains in all groups, paralleling estimates of freedom from major amputation and maintenance of artery patency |
Devine (2016)12 | 323 adults with moderate to severe claudication, multicenter | Medical management (including physician-recommended exercise therapy, smoking cessation, and/or medications) or surgical/endovascular revascularization | ABI | 3 domains of modified WIQ (distance, speed, stair-climbing); WIQ pain domain, VascuQoL, EQ-5D, CSI | 12 months | At 12 months, both the medical and revascularization groups had improved WIQ, VascuQoL, and EQ-5D scores, and fewer symptoms as measured by CSI, but the revascularization group had greater improvement as compared to medical management alone |
McDermott (2018)30 (HONOR study) | 200 patients with PAD, multicenter | Usual care or a home-based exercise program with a wearable activity monitor and telephone coaching | 6-minute walk distance | Subscales of WIQ, SF-36, and PROMIS | 9 months | Exercise intervention was associated with a worse PROMIS pain interference score and a smaller degree of improvement in walking distance |
