Quality of Life and Peripheral Arterial Disease

Peripheral arterial disease (PAD) is a common disease entity with the potential to cause considerable impairment in the quality of life (QoL) of millions of Americans. As there is no exact cure for PAD, thus representing a chronic illness, the goal of treatment is disease management including the prevention of cardiovascular events, and improving QoL by helping people with PAD live productive and satisfying lives. Disagreement exists between patients’ clinically inferred QoL status and their perceptions of QoL exist concerning PAD. Whereas a clinician may be concerned with a physiological or anatomical abnormality that may ultimately lead to disease and discomfort, a patient may be more concerned with their overall sense of QoL, which is only in part related to their clinical health status. Thus, to truly understand the outcomes of PAD and its treatment, it is necessary to supplement the traditional clinical outcome measures with information from the patient point of view. In this article, we review measurement instruments available to assess patient-reported QoL, and discuss the potential these tools have for providing accurate and meaningful information to complement traditional clinical outcome data.
