Brief summary
Peripheral arterial disease (PAD), a disabling condition, affects 800,000 Canadians. People with PAD suffer from poor quality of life due to leg pain, which makes walking difficult. They also have a high risk of heart disease. In November of 2017, the University of Ottawa Heart Institute (UOHI) launched Canada's first specific walking rehabilitation and cardiovascular risk reduction program dedicated to patients with PAD. An on-site, supervised exercise program to improve walking endurance and quality of life in PAD has been shown to be successful. However many patients are not able to participate in the on-site program due to barriers such as transportation, parking, or other commitments. Recently, a home-based walking program has also been shown to significantly improve walking endurance and quality of life among people with PAD. It was decided that a hybrid program, that has a short on-site program followed by a home-based program may allow more patients to participate and have the highest chance of success. The goal is to develop a new hybrid program for medical care in PAD patients in order to: (a) improve their walking distance, (b) improve their quality of life and (c) improve their cardiovascular risk. As part of this study the investigators will enrol 25 participants with PAD. Participants will be studied at baseline (before their first on-site class) and at 3 month follow up (after their last home program phone call).
