After years of working with patients who’ve been confused by overlapping vascular terms, one thing is clear: the distinction between peripheral artery disease (PAD) and peripheral artery disease (PVD) isn’t just medical semantics—it can shape your treatment path and long-term outcomes.
Based on our clinical experience, PAD is often under-recognized as a more specific and serious form of the other that demands targeted intervention. In this guide, we break down the critical differences, clarify common misconceptions, and share diagnostic and treatment insights.
Peripheral Artery Disease (PAD) silently ravages the body, obstructing the flow of blood to the extremities, particularly the legs. This condition is often caused by the accumulation of fatty deposits in the arteries, a condition known as atherosclerosis.
Other factors that can cause it include blood clots or inflammation in the arteries, or less commonly, injury to the limbs, unusual anatomy of the ligaments or muscles, or radiation exposure.
While often silent in its early stages, it may present a range of symptoms as it progresses. These symptoms are indicative of the disease's progression and are crucial for diagnosis and determining treatment options.
The most common symptom is claudication, characterized by muscle pain or cramping in the legs when walking, climbing stairs, or exercising. This pain usually subsides during rest.
This condition is not confined to arteries but involves any blood vessel outside the heart, which could be arteries, veins, or lymphatic vessels. PVD is a circulation disorder that causes blood vessels outside the heart to narrow, block, or spasm.
A cause analysis shows that it is usually triggered by atherosclerosis, the build-up of fatty deposits in the vessel walls. Other causes include blood clots or embolism, inflammation, or infection.
Often, individuals with it may not exhibit any symptoms until the disease has significantly progressed. This can make timely diagnosis and treatment challenging. However, when symptoms do manifest, they can range from mild discomfort to severe pain.
Some commonly reported symptoms of Peripheral Vascular Disease include:
The second is a broader term that refers to any disease or disorder of the circulatory system outside of the heart, while the first is a type of PVD that specifically involves disease of the blood vessels supplying the arms and legs.
One key similarity between them lies in their risk factors. Both conditions are strongly linked to smoking, diabetes, hypertension, and high cholesterol. Age and family history also play a significant role in the development of these diseases.
“In over two decades of vascular care, we’ve seen countless patients misled by generalizations—treating Peripheral Artery Disease (PAD) as interchangeable with Peripheral Vascular Disease (PVD). But PAD isn’t just a subset; it’s the red flag. It’s the signal of deeper arterial compromise that, if overlooked, can escalate into limb-threatening complications. From our clinical lens, clarity in diagnosis isn’t optional—it’s the difference between conservative management and life-altering intervention.”
These statistics back up what we see every day in the clinic—PAD is often overlooked, but it carries serious risks. Clear diagnosis and early action save lives and limbs.

Understanding the distinction between the two isn’t just a matter of terminology—it can shape outcomes and even save lives.
Based on years of clinical experience, here’s what we’ve consistently observed:
We've seen many patients whose early symptoms were misclassified as general vascular issues, delaying vital treatment.
Here’s where it often goes wrong:
If you or someone you care about is experiencing symptoms:
“In our opinion, clearer language leads to better care. The right diagnosis—early—can change everything.”
Peripheral artery disease (PAD) and vascular disease are both conditions that affect the circulatory system, but they involve different areas. PAD specifically involves problems with blood flow in the arteries that supply blood to the legs and feet. On the other hand, vascular disease is a more general term that includes all conditions that affect the circulatory system, including PAD, but also conditions that affect veins, capillaries, or the lymphatic system.
Several red flags for peripheral vascular disease should prompt a visit to the doctor. These include chronic leg or foot pain, especially while walking or exercising; wounds on the feet or legs that heal slowly or not at all; a decrease in the temperature of your lower leg or foot compared to the rest of your body; or changes in the color of your legs.
Certain drugs can contribute to the development of peripheral vascular disease. These include some hypertension medications, certain migraine medications, oral contraceptives, and certain chemotherapy drugs. It's important to discuss the risks and benefits of these medications with your doctor.
Three signs of peripheral arterial disease include intermittent claudication, which is pain or discomfort in the legs during exercise that subsides with rest; coldness in your lower leg or foot, particularly when compared with the other leg; and a change in the color of your legs, often becoming pale or blue.
Determining whether leg pain is vascular or muscular often requires a medical evaluation. Vascular pain is often associated with activities like walking and is relieved with rest, while muscular pain can occur at rest or during activity and may be associated with specific movements or positions. Muscular pain is often relieved by rest, whereas vascular pain tends to be more consistent.
Yes, you can have both peripheral artery disease (PAD) and peripheral vascular disease (PVD) at the same time. PAD is a type of PVD, so if you have PAD, by definition, you also have PVD. However, you can also have other forms of PVD in addition to PAD.
The end stage of peripheral vascular disease, also known as critical limb ischemia, is characterized by consistent pain, even at rest, and serious tissue damage that can lead to ulcers, gangrene, and potentially amputation if not treated promptly and effectively.
Yes, you can have peripheral vascular disease (PVD) without having peripheral artery disease (PAD). PVD is a broader term that includes any disease or disorder of the circulatory system outside of the brain and heart, including diseases of the veins, arteries, and lymph vessels or blood disorders that affect circulation.
Legs with peripheral artery disease can show several signs. They may be pale or have a bluish color, feel cold to the touch, and have weak or absent pulses. Sores and wounds on the legs and feet may not heal properly, and there may be a notable decrease in hair growth on the legs and feet.
The life expectancy with peripheral artery disease (PAD) can vary widely based on the individual and the severity of the disease. With proper management, including lifestyle changes and treatment of underlying conditions like diabetes or high cholesterol, many people with PAD can live a long and healthy life.
Several conditions can be mistaken for peripheral artery disease, including sciatica, deep vein thrombosis, and restless leg syndrome. These conditions can cause similar symptoms, such as leg pain and discomfort, but the causes and treatments are different.
The best position to sleep in with peripheral artery disease is often elevated. This is because elevation can help improve circulation to the legs, which can help relieve discomfort and prevent further complications. However, the best position can vary based on the individual and the severity of their condition, so it's always a good idea to consult with a healthcare provider.
