Peripheral vascular disease and depression.

The occurrence of peripheral vascular disease (PVD) in our aging population is of great proportion affecting approximately 20% of the population, which extrapolates to 8 to 12 million Americans. PVD is a progressive disease that almost always includes one or more comorbidities that impact greatly on severity and management of the disease. The age of disease onset can vary but most commonly presents at age 65 years and older.
