Vascular Health & Peripheral Artery Disease
Your vascular system is a network of arteries and veins that reaches every organ. When plaque narrows leg arteries — peripheral artery disease (PAD) — the warning is not only about the legs; it is about your entire cardiovascular risk. This guide explains what to watch for, how PAD is diagnosed, and the range of modern, in-office treatments.

Your vascular system in plain language
Arteries carry oxygen-rich blood away from the heart; veins return it. Problems in either system show up as pain, swelling, wounds, or changes in skin and temperature — and often signal the same underlying process (atherosclerosis) that causes heart attacks and strokes.
Because vascular disease is often silent early on, screening matters more than most patients realize — especially if you have diabetes, high blood pressure, or a smoking history.
What peripheral artery disease is
PAD is the buildup of plaque in the arteries that supply the legs. Reduced flow starves muscles of oxygen during activity, causing cramping or fatigue that resolves with rest — a symptom called claudication. Advanced PAD can cause pain at rest, non-healing wounds, or in severe cases, tissue loss.
PAD is not just a leg problem. Patients with PAD have a significantly higher risk of heart attack and stroke. Identifying and treating PAD is part of protecting the heart.
Symptoms most people miss
Common signs include leg or calf pain when walking that improves with rest, cold or discolored feet, hair loss on the lower legs, slow-healing sores, and unexplained leg fatigue. Many patients attribute these to aging and never mention them — until a wound appears.
Venous problems present differently: heaviness, aching, visible varicose veins, swelling that worsens by evening, and skin changes around the ankles.
How PAD is diagnosed
The first-line test is an ankle-brachial index (ABI), a simple comparison of blood pressure at the ankle and the arm. Ultrasound imaging identifies where narrowings are and how significant they are. When intervention is being planned, catheter-based angiography provides the highest-resolution view.
For venous disease, duplex ultrasound maps reflux and clots. These studies are quick, painless, and done in-office.
Treatments — from lifestyle to catheter procedures
Foundational therapy is aggressive risk-factor control: smoking cessation, statin therapy, blood pressure and diabetes management, and a structured walking program that genuinely reprograms the muscles' ability to work with limited flow.
When lifestyle and medication aren't enough, minimally invasive catheter procedures — angioplasty, atherectomy, and stenting — can restore flow through a small puncture in the groin or wrist. Related techniques like genicular artery embolization address chronic knee pain from arthritis by targeting abnormal vessels rather than replacing the joint.

When to see a cardiologist
Vascular symptoms are easy to normalize. Getting evaluated early often prevents wounds, hospitalizations, and amputations later.
- Chest pain, pressure, or tightness — especially with exertion or shortness of breath.
- Palpitations, fainting spells, or a heart rhythm that feels irregular.
- Leg pain when walking, non-healing wounds, or new leg swelling.
- Family history of early heart disease, or personal history of high blood pressure, diabetes, or high cholesterol.
- You want a proactive, preventive evaluation and a personalized plan.
