Supervised Exercise Versus Primary Stenting for Claudication Resulting From Aortoiliac Peripheral Artery Disease: Six-Month Outcomes From the Claudication Exercise Versus Endoluminal Revascularization (CLEVER) Study
Background — Claudication is a common and disabling symptom of peripheral artery disease that can be treated with medication , supervised exercise ( SE ) , or stent revascularization ( ST ) . Methods and Results — We r and omly assigned 111 patients with aortoiliac peripheral artery disease to receive 1 of 3 treatments : optimal medical care ( OMC ) , OMC plus SE , or OMC plus ST . The primary end point was the change in peak walking time on a grade d treadmill test at 6 months compared with baseline . Secondary end points included free-living step activity , quality of life with the Walking Impairment Question naire , Peripheral Artery Question naire , Medical Outcomes Study 12-Item Short Form , and cardiovascular risk factors . At the 6-month follow-up , change in peak walking time ( the primary end point ) was greatest for SE , intermediate for ST , and least with OMC ( mean change versus baseline , 5.8±4.6 , 3.7±4.9 , and 1.2±2.6 minutes , respectively ; P<0.001 for the comparison of SE versus OMC , P=0.02 for ST versus OMC , and P=0.04 for SE versus ST ) . Although disease-specific quality of life as assessed by the Walking Impairment Question naire and Peripheral Artery Question naire also improved with both SE and ST compared with OMC , for most scales , the extent of improvement was greater with ST than SE . Free-living step activity increased more with ST than with either SE or OMC alone ( 114±274 versus 73±139 versus −6±109 steps per hour ) , but these differences were not statistically significant . Conclusions — SE results in superior treadmill walking performance than ST , even for those with aortoiliac peripheral artery disease . The contrast between better walking performance for SE and better patient-reported quality of life for ST warrants further study .
