Journal Review in Vascular Surgery: Beef to Biologics - The Cutting Edge of Medical Management for Peripheral Arterial Disease

Peripheral artery disease has been called the ‘silent circulatory crisis’—affecting millions, limiting mobility, and quietly raising the risk of heart attack, stroke, and limb loss. For decades, treatment focused on walking programs, aspirin, and sometimes a stent or bypass. But today, the landscape is changing. From PCSK9 inhibitors that drive cholesterol to record lows, to GLP-1 agonists like semaglutide improving walking distance, to novel antithrombotic strategies that balance bleeding and clotting—PAD care is entering a new era. In this episode, we’ll explore the breakthroughs, the evidence behind them, and what they mean for patients who just want to keep moving forward.

Hosted by the University of Michigan Department of Vascular Surgery:
- Robert Beaulieu, Program Director
- Frank Davis, Assistant Professor of Surgery
- Luciano Delbono, PGY-5 House Officer
- Andrew Huang, PGY-4 House Officer
- Carolyn Judge, PGY-2 House Officer

Learning objectives:
1. Describe the current evidence-based recommendations for multifactorial medical management of peripheral artery disease (PAD), including lipid, glycemic, and antithrombotic strategies per 2024 SVS/AHA guidelines.

2. Interpret the clinical implications of the FOURIER trial regarding the role of PCSK9 inhibition in reducing cardiovascular events in patients with atherosclerotic disease, including PAD.

3. Evaluate the emerging role of GLP-1 receptor agonists, such as semaglutide, in improving walking performance and quality of life among patients with diabetic PAD based on findings from the STRIDE trial.
