Association of Disease Progression With Cardiovascular and Limb Outcomes in Patients With Peripheral Artery Disease: Insights From the EUCLID Trial.

Background: Patients with peripheral artery disease have a high risk of future cardiovascular disease events and mortality. Little is known about the changes in symptom classification over time in patients with peripheral artery disease and the association of changes in symptom classification with subsequent cardiovascular disease events.

Methods: In this analysis of the EUCLID trial (Examining Use of Ticagrelor in Peripheral Artery Disease), we examined the changes in Rutherford classification (RC) of patients over 12 months.
