Brief summary
This study will investigate if patients with peripheral artery disease (PAD) can be successfully incorporated into an already existing Cardiac Rehabilitation programme. One group of PAD patients will exercise as a group, and the other group will exercise alongside patients with coronary artery disease (CAD).
Detailed description
Peripheral artery disease (PAD) is a progressive disease that occurs as the result of atherosclerotic plaque formation in the major arteries of the leg (Mays, Casserly and Regesteiner, 2013). The main presenting symptom of PAD is intermittent claudication (IC) - exertional pain or discomfort in the calf, thigh or buttock that is relieved with rest. The presence of PAD is a very powerful marker of cardiovascular risk and preventable cardiovascular deaths. Following the initial diagnosis of PAD, for those patients without coronary artery disease the risk of systemic morbidity or mortality in the next 5 years is 50% (AACVPR, 2013). In 2012, the National Institute for Health and Care Excellence (NICE) issued guidelines stating that supervised exercise programmes (SEPs) should be offered as first-line treatment for people diagnosed PAD. However, there is a national shortage of dedicated SEPs for PAD patients that UK vascular specialists can refer patients to. There has been suggestion that an already established network of Cardiac Rehabilitation (CR) departments within the United Kingdom (UK) could cater for this group of patients, as they already have facilities and staff in place. To date, there has been no investigation into whether this would be successful. This research project would investigate if CR programmes could get the same outcomes for PAD patients as a stand-alone PAD rehabilitation programme. The study would investigate the possible positive and negative impact on both the PAD and CR patient groups in attending a combined rehabilitation programme of exercise and education. It will also look at the perceptions of the participants regarding the treatment programme itself.

Inclusion criteria
* General criteria As part of this study participants will be required to wear an accelerometer on the first week and last week of the 12 week study. The accelerometer will be kept in place by a medical dressing (e.g. Tegederm). People with an existing skin condition such as psoriasis or eczema that would be affected by the application of a medical dressing will be excluded from the study. All participants must be able to start the incremental shuttle walk test (walking speed of 1.8kph, 1.1 mph). All participants must be able to engage in the exercises prescribed in the programme Inclusion Criteria - PAD patients: All patients recruited will have had a recent diagnosis (0 - 12 months) of PAD made by either a vascular surgeon, vascular specialist nurse or specialist podiatrist. Inclusion Criteria - CAD patients: All patients recruited to the CR group will have had a recent diagnosis (0-12 months) of CAD (angina, myocardial infarction (MI), or coronary artery bypass graft (CABG) or valve surgery).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Walking distance | 12 weeks | Initial and maximal pain free walking distances are measured using a Incremental Shuttle Walk Test. The symptoms of claudication pain are identified using the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) 0-4 Claudication scale. 0 is no claudication; 1 is initial pain; 2 is moderate pain; 3 is severe; 4 is maximal pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Walking Impairment Questionnaire | 12 weeks | Patient's perceived walking distance and speed related to their claudication pain. Participants rate the distance and speed they are able to walk at. The distances are separated in to the amounts of blocks they can walk (with and without impairment). They then rate the speed they can walk 100 yards. The lower the score the worse the perceived limitation of their claudication symptoms. |
| King's College Vascular Quality of Life Questionnaire (VascQual) | 12 weeks | Disease-specific quality of life questionnaire. The questionnaire is 25-item questionnaire subdivided into five domains: pain (4 items), symptoms (4 items), activities (8 items), social (2 items), and emotional (7 items). The higher the score the lower the health-related quality of life. |
| Free-living physical activity levels | 12 weeks | Accelerometer data recording activity levels outside of rehabilitation programme |
| Hospital Anxiety and Depression Scale | 12 weeks | The is a generic quality of life questions that assesses levels of anxiety and depression. There are 14 questions questions in total, 7 questions on anxiety and 7 on depression. Each question has an answer rating from 0-3, with 0 being no evidence of anxiety/depression, and 3 being maximum score. The total score for anxiety and depression are added (but anxiety and depression scores are not combined) to see the total reading for anxiety and depression. If 11 or above is scored in either anxiety or depression, then referral to appropriate health care professional is discussed with participant. |
