Depression and Physical Activity in PAD: Addressing the Missing Link

Peripheral artery disease (PAD) is a prevalent and progressive atherosclerotic condition characterized by impaired limb perfusion and reduced mobility 1) .With a globally aging population, the burden of PAD is expected to increase, highlighting the need for comprehensive management strategies 1,2) .The Behavioral Intervention by Allied Health Professionals to Promote Physical Activity (BIP) trial 3) was a multicenter randomized clinical study aimed at evaluating whether brief counseling by allied health professionals could significantly increase daily step counts in individuals with PAD who were able to walk (n = 200).Participants in the intervention group received two 60-minute in-person behavioral counseling sessions and two 15-minute follow-up phone calls, whereas the control group received four 15-min phone calls delivering general health education about PAD.Both groups were advised to walk at least three times per week for a minimum of 40 min per session.Although the intervention did not significantly increase daily step counts, it did improve PAD-specific quality-of-life measures 3) , which have been associated with a lower risk of major adverse cardiovascular events (MACE) 4) .Traditional PAD management emphasizes supervised exercise therapy for non-critical limb ischemia and revascularization for critical limb ischemia.However, the role of mental health, particularly depression, has historically received less attention despite its well-established association with poor outcomes in patients with PAD 5,6) .In a timely post hoc analysis of the BIP trial, Golledge et al. examined the impact of pharmacologically treated depression on long-term physical activity in patients
