title: Efficacy of optimal long-term management of multiple cardiovascular risk factors (CVD) on walking and quality of life in patients with peripheral artery disease (PAD): protocol for randomized controlled trial.
abstract: Peripheral artery disease (PAD) is an understudied chronic illness most prevalent in elderly individuals. PAD patients experience substantial walking impairment due to symptoms of limb ischemia that significantly diminishes quality of life (QOL). Cardiovascular disease (CVD) morbidity and mortality is increased in this population because of aggressive atherosclerosis resulting from untreated CVD risk factors. Despite current national guidelines recommending intensive CVD risk factor management for PAD patients, untreated CVD risk factors are common. Interventions that bridge this gap are imperative. The Vascular Insufficiency - Goals for Optimal Risk Reduction (VIGOR(2)) study is a randomized controlled trial (RCT) that examines the effectiveness of a long-term multifactor CVD risk reduction program on walking and quality of life in patients with PAD. The purpose of this article is to provide a detailed description of the design and methods of VIGOR(2). Clinical Trial Registration - URL: http://clinicaltrials.gov/ct2/show/NCT00537225.
