| Study acronym | MIMIC |
| Study objectives | The aim of the MIMIC trials is to assess the adjuvant benefit of percutaneous transluminal angioplasty (PTA) in patients with Mild to Moderate Intermittent Claudication (MIMIC). All patients will receive best medical treatment, including advice to stop smoking and receive supervised exercise training for 6 months. 340 patients from 10 centres will be randomly allocated to receive angioplasty or not into one of two trials, one for aorto-iliac disease and another for femoro-popliteal disease and followed up for 2 years. It is expected that the MIMIC trials will show whether either aorto-iliac or femoro-popliteal angioplasty are of adjuvant benefit to best medical treatment and exercise therapy in terms of Absolute Walking Distance (AWD) as the primary endpoint, and secondly in terms of both specific and generic health related quality of life (HRQL) measures and, if beneficial, the cost effectiveness of the additional intervention. |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Adult |
| Sex | All |
| Target sample size at registration | 340 |
| Key inclusion criteria | 1. Patients with stable mild to moderate intermittent claudication 2. Patients satisfying the criteria of the Edinburgh Claudication Questionnaire 3. Patients suitable for aorto-iliac or femoro-popliteal PTA after duplex mapping or diagnostic arteriography 4. Ankle Brachial Pressure Indices (ABPI) <0.9 or >0.9 with a positive stress test i.e. a fall of >30 mmHg following a treadmill test at 4 km/h, 10 degree slope for 1 min |
| Key exclusion criteria | 1. Patients with intermittent claudication too mild for patient or doctor to consider PTA 2. Patients with intermittent claudication severe enough to merit consideration of bypass surgery 3. Patients with critical ischaemia i.e. absolute Doppler pressure <50 mmHg, or presence of ulcers or gangrene with a Doppler pressure >50 mmHg 4. Patients with ankle/brachial pressure index (ABPI) >0.9 with a negative stress test who could have sciatica or very mild peripheral arterial disease (insignificant arterial disease) 5. Patients with musculoskeletal, cardiac or any other concomitant disease that renders consideration for supervised exercise inappropriate |
