For PAD Awareness Month, Vital Heart & Vein vascular and endovascular surgeon Dr. Dylan Brooks joined KPRC to discuss new research on GLP-1 medications and peripheral artery disease (PAD).
What is PAD? Peripheral artery disease is a blockage in the arteries that restricts blood flow, most often to the legs. It can start subtly. A common early sign is cramping in the calf, thigh, or buttock that comes on with walking and improves with rest. Many people brush it off as a normal part of getting older, but it’s a classic early symptom. A wound on a toe or foot that isn’t healing is more serious and should be evaluated urgently by a vascular specialist.
What did the new study find? Dr. Brooks described a large, real-world study published this summer. It compared people who had both PAD and type 2 diabetes, with one group taking metformin and another taking GLP-1 medications. Over five years, the GLP-1 group had lower rates of hospitalization, death, procedures to restore blood flow to a limb, and amputation.
What does it mean? Dr. Brooks emphasized that this was an observational study, so it can’t prove GLP-1 medications were responsible for the better outcomes. It is an encouraging signal, though. Early evidence suggests GLP-1s may support blood vessel function by reducing inflammation, and an earlier randomized study found improved pain-free walking distance and quality of life in patients with PAD. More research is needed.
Add this section to the Dr. Brooks post, after “What does it mean?”:
What this means if you already have PAD. In a second TV interview, on KHOU, Dr. Brooks stressed that GLP-1 medications aren’t a replacement for proven PAD treatment. The foundation is still antiplatelet therapy such as aspirin, a high-intensity statin to stabilize plaque, regular walking and exercise, and staying away from tobacco. If you smoke, he noted, no medication can make up for it. If you already have a reason to take a GLP-1, such as diabetes or obesity, it’s reasonable to talk with your doctor about whether one is right for you.
