Title: Increasing Activity in Peripheral Arterial Disease
Brief Summary: Lower extremity peripheral arterial disease (PAD) is a disease in which fatty build-up, or plaque, accumulates in the arteries of the legs. People with lower extremity PAD often experience leg pain while walking, which is caused by reduced blood flow to the legs. Regular walking has significant benefits for people with blood flow problems in their legs, but previous studies have shown that most men and women with PAD do not walk for exercise on a regular basis. A group home-based walking program may help people with PAD to walk more often and improve their lower extremity functioning. This study will evaluate the effectiveness of a home-based group mediated cognitive behavioral (GMCB) exercise program in helping people with lower extremity PAD to increase their walking frequency and improve their lower leg functioning.


Options:
A: Inclusion Criteria:

* Essential hypertension grade 1 - 2 without medical treatment

Exclusion Criteria:

* End organ damage
* Two or more cardiovascular risk factors
* Diabetes
B: 1. Subjects with NAFLD determined by MRS ;
2. Age 40-65 years old;
3. Waist circumference\> 90cm for men and \> 85cm for women.
C: Inclusion Criteria:

* Have PAD
* Potential participants with a resting ABI greater than or equal to 0.91 and less than or equal to 1.00 at their baseline visit will be eligible if their ABI drops by at least 20% after the heel-rise test. Potential participants with a resting baseline ABI greater than 0.91 who do not meet criteria for inclusion based on the heel-rise test can be eligible if they have data from a certified non-invasive vascular laboratory that demonstrates presence of lower extremity ischemia. However, more evidence than an abnormal PVR from the non-invasive vascular laboratory is required (for example, a toe brachial index pressure less than 0.60). Finally, potential participants who do not meet the above criteria for inclusion will be eligible if they have an angiogram demonstrating greater than 50% stenosis on one or more lower extremity arterial vessels.

Exclusion Criteria:

* Below or above knee amputation
* Wheelchair confinement
* Uses a walking aid other than a cane (e.g., walker)
* Unable to return to the medical center at the required visit frequency
* Greater than Class II New York Heart Association heart failure or angina (symptoms at rest or with minimal exertion)
* Any increase in angina pectoris symptoms during the 6 months before study entry or angina at rest
* Presence of a foot ulcer
* Lower extremity revascularization or major orthopedic surgery during the 3 months before study entry
* Heart attack or coronary artery bypass grafting during the 3 months before study entry
* Major medical illnesses, including treatment for cancer (except non-melanoma skin cancer) during the 12 months before study entry
* Planned lower extremity revascularization within the 12 months after study entry
* Current participation in another clinical trial
* Walking for exercise at a level comparable to that targeted in the study's intervention
* Completion of a cardiac rehabilitation program within 3 months before study entry
* Coronary ischemia during exercise, defined as ST segment depression greater than 1 mm during the baseline exercise treadmill test, with or without associated chest discomfort
* Left-bundle branch block or significant ST-T wave changes on the baseline ECG without a perfusion stress test, demonstrating no reversible ischemia within the 3 months before study entry
* Stopping during the treadmill exercise stress test because of chest pain, shortness of breath, hip or knee arthritis. These individuals will be interviewed by the principal investigator and will be excluded only if it is determined that their walking performance (based in part on the treadmill test) is limited by a comorbidity other than leg ischemia.
* Unable to walk at least 50 feet without stopping during the 6-minute walk test
* Stopping during the 6-minute walk test for symptoms other than ischemic leg symptoms
* Mini-Mental Status Examination (MMSE) score of less than 23 or psychiatric illness
* Failure to complete a study run-in period
* Parkinson's disease
* Requires oxygen with exertion.
