Peripheral Artery Disease: Symptoms, Causes, How to Manage It, and Prevention Steps

Have you ever felt pain or cramping in your legs while walking that goes away after you rest? Do not take this symptom lightly, because it may be a sign of Peripheral Artery Disease (PAD), a serious condition that often goes unnoticed. Have it confirmed through a doctor’s examination. This disease not only affects quality of life but can also increase the risk of more severe health complications, such as a heart attack or stroke.

In Indonesia, where modern lifestyles are becoming more and more common, PAD cases are also being found more often. However, many people do not yet understand how important it is to recognize the symptoms and take preventive steps early.

This article covers peripheral artery disease in full, from its symptoms and causes to how to manage it, so you can be more alert and take the right action to keep your heart and blood vessels healthy.

What Is Peripheral Artery Disease?

Peripheral artery disease, also known as Peripheral Arterial Disease (PAD) or peripheral vascular disease, is a condition in which the arteries become narrowed or blocked, especially in the legs. This blockage is usually caused by a buildup of plaque (fat, cholesterol, and other substances) in the blood vessel walls, known as atherosclerosis. As a result, the blood flow that should carry oxygen and nutrients to the limbs is reduced. PAD can occur in various parts of the body, but it most often affects the legs.

How PAD Affects Blood Flow to the Limbs, Especially the Legs

When the arteries narrow or become blocked, blood flow to the affected part of the body, such as the legs, is reduced. This causes symptoms such as pain, cramping, or tiredness in the legs when walking or being active, which usually go away with rest (a condition called intermittent claudication). In more severe cases, very limited blood flow can cause leg wounds that are slow to heal, numbness, or even tissue death (gangrene). If left untreated, PAD can increase the risk of serious complications such as amputation or heart disease.

Prevalence of Peripheral Artery Disease in Indonesia

Although specific data on the prevalence of PAD in Indonesia is still limited, several studies show that the high rates of risk factors such as diabetes, smoking, and hypertension in Indonesia contribute to the rise in PAD cases. According to Indonesia’s Basic Health Research (Riskesdas) 2018, the prevalence of diabetes in Indonesia reached 10.9% in people over 15 years of age, and hypertension reached 34.1%. Both conditions are major risk factors for PAD *. In addition, an inactive lifestyle and an unhealthy diet also increase the risk of PAD. (* Source: Laporan Riskesdas 2018 Nasional)

Globally, an estimated more than 200 million people worldwide have PAD, with prevalence continuing to rise with age. In Indonesia, although there is no comprehensive national data yet, PAD is considered a health problem to watch out for, especially among older adults and people with a history of cardiovascular disease.

Signs of Peripheral Artery Disease to Watch Out For

Many people do not realize they have PAD, because the symptoms often appear gradually and may be dismissed as minor. In this section, we discuss the common symptoms to look out for, the more serious symptoms that can signal a blood flow problem, and the signs that show when you should seek medical help right away.

Common Symptoms of Peripheral Artery Disease

Peripheral artery disease (PAD) often causes symptoms that appear gradually and get worse over time. Some common symptoms that people with PAD often experience include:

• Pain or cramping in the legs, especially when walking, climbing stairs, or doing physical activity. This pain usually goes away after rest (called intermittent claudication).
• Legs that feel weak or heavy, especially after walking or standing for a long time.
• Legs that feel cold or numb, especially in one leg.
• Changes in the skin color of the legs, such as turning pale or bluish.
• Slow toenail growth or hair loss on the legs.

More Serious Symptoms

If PAD is not treated, symptoms can become more severe and carry a risk of serious complications. Symptoms that indicate PAD has reached an advanced stage include:

• Constant leg pain, even while resting.
• Wounds or ulcers on the legs or feet that do not heal, especially on the toes or heels.
• Skin turning dark or blackish, which indicates tissue death (gangrene).
• Swelling in the legs accompanied by severe pain.
• Infections in the legs or feet that are hard to treat and can spread to other parts of the body.

When to Seek Medical Help Immediately

Some emergency conditions related to PAD require medical treatment as soon as possible. Contact a doctor or go to a hospital immediately if you experience:

• Severe, sudden leg pain, especially if the leg also feels cold and looks pale. This may indicate an acute artery blockage.
• Wounds or ulcers on the legs or feet that do not heal, are painful, or discharge pus.
• Skin turning black or the appearance of dead tissue on the legs or feet.
• Fever or signs of infection such as redness, swelling, or warmth around a wound.

What Causes Peripheral Artery Disease?

Many people do not realize that certain lifestyle and health factors can increase their chances of developing PAD. In this section, we explain the main cause of PAD, the various risk factors to look out for, and how lifestyle changes can help lower the risk of this disease.

Main Cause of Peripheral Artery Disease

The main cause of peripheral artery disease (PAD) is atherosclerosis, a buildup of plaque (fat, cholesterol, and other substances) in the artery walls. This plaque causes the blood vessels to narrow or become blocked, so blood flow to certain parts of the body, especially the legs, is reduced. Besides atherosclerosis, PAD can also be caused by inflammation of the blood vessels, injury to the limbs, or radiation exposure. However, these cases are less common than atherosclerosis.

Risk Factors That Can Increase the Likelihood of Peripheral Artery Disease

Several risk factors can increase a person’s likelihood of developing PAD. These factors include:

• Age: The risk of PAD increases with age, especially over 50.
• Smoking: Smoking damages blood vessels and speeds up plaque buildup.
• Diabetes: High blood sugar levels can damage blood vessels and nerves, increasing the risk of peripheral vascular disease.
• Hypertension (high blood pressure): Uncontrolled blood pressure can damage the artery walls.
• High cholesterol: High levels of LDL cholesterol (bad cholesterol) contribute to plaque formation.
• Family history: If a family member has PAD or cardiovascular disease, your risk also increases.
• Obesity: Excess body weight puts extra strain on the circulatory system.

How Lifestyle Can Affect the Risk of Peripheral Artery Disease

Lifestyle plays an important role in determining a person’s risk of PAD. Habits such as smoking, lack of physical activity, and an unhealthy diet (high in fat and sugar) can worsen the condition of the blood vessels. On the other hand, adopting a healthy lifestyle, such as exercising regularly, eating a balanced diet, and avoiding cigarettes, can help reduce the risk of PAD.

For example, physical activity such as walking or cycling can improve blood circulation and keep the blood vessels healthy. In addition, controlling blood sugar, blood pressure, and cholesterol levels through a healthy diet and the right treatment is also very important to prevent PAD. By changing to a healthier lifestyle, you not only reduce your risk of PAD but also improve your overall quality of life.

How Is Peripheral Artery Disease Diagnosed?

Diagnosing peripheral artery disease (PAD) is very important for determining the right treatment steps. Below are the steps doctors generally take to diagnose peripheral artery disease, from a physical examination to additional tests that may be needed.

The Diagnostic Process for Peripheral Artery Disease

Diagnosing peripheral vascular disease, or peripheral artery disease (PAD), usually begins with a physical examination and a medical interview by the doctor. The doctor will ask about your symptoms, medical history, and risk factors such as smoking, diabetes, or high blood pressure. Next, the doctor will perform a physical examination, including:

1. Checking the pulses in the legs and feet: A weak or absent pulse can be a sign of reduced blood flow.
2. Observing the condition of the skin and toenails: Changes in skin color, wounds that do not heal, or abnormal nail growth can indicate PAD.

After the initial examination, the doctor may perform a simple test called the Ankle-Brachial Index (ABI). This test compares the blood pressure at the ankle with the blood pressure in the arm. If the results show a significant difference, this may indicate PAD.

Additional Tests That May Be Needed

If the results of the initial examination suggest possible peripheral vascular disease, the doctor may recommend additional tests to confirm the diagnosis and assess the severity of the condition. These tests include:

• Doppler ultrasound: This test uses sound waves to visualize blood flow in the arteries. It helps the doctor see areas that are narrowed or blocked.
• Angiography: This procedure involves injecting a contrast agent into the blood vessels and then taking images using X-rays, a CT scan, or MRI. Angiography gives a detailed picture of the location and extent of the blockage.
• Treadmill test: This test is done to observe PAD symptoms, such as leg pain, while the patient walks on a treadmill. The results help the doctor assess how severe the condition is.
• Blood test: A blood test is done to check cholesterol levels, blood sugar, and other markers that may contribute to PAD.

With a combination of a physical examination and additional tests, the doctor can diagnose PAD accurately and plan appropriate treatment.

Treatment and Management Steps

Below are the various approaches that can be taken to manage peripheral artery disease (PAD), from non-invasive treatment, such as lifestyle changes and medication, to medical and surgical procedures when needed.

Non-Invasive Treatment

Non-invasive treatment is the first step in managing peripheral artery disease (PAD). The focus is on lifestyle changes and medication to manage symptoms and prevent the disease from progressing.

1. Lifestyle changes: Lifestyle changes are key to managing PAD. Some steps you can take include:
   • Quitting smoking: Smoking worsens the condition of the blood vessels, so quitting smoking is the most important step.
   • Regular exercise: Physical activity such as walking can improve blood circulation and reduce PAD symptoms.
   • Healthy diet: Eating foods that are low in fat, high in fiber, and low in salt helps control cholesterol and blood pressure.
   • Maintaining an ideal body weight: Losing excess weight can reduce the strain on the circulatory system.
2. Commonly prescribed medications: The doctor may prescribe medications to help manage PAD, such as:
   • Blood thinners (for example, aspirin or clopidogrel) to prevent blood clots.
   • Cholesterol-lowering drugs (statins) to reduce plaque buildup in the arteries.
   • Drugs to improve blood flow (cilostazol or pentoxifylline) that help reduce leg pain.

Medical and Surgical Procedures

If non-invasive treatment is not effective enough or PAD is already severe, the doctor may recommend a medical or surgical procedure.

• Angioplasty and stenting: This procedure is done by inserting a catheter into the narrowed blood vessel. A small balloon is then inflated to open the artery, and a stent (a small metal mesh tube) is placed to keep the artery open.
• Bypass surgery: In more severe cases, bypass surgery may be needed. The doctor creates a new route using a healthy blood vessel or an artificial vessel so that blood can flow around the blocked area.

The Importance of Managing Coexisting Conditions

Managing coexisting conditions such as diabetes and hypertension is very important in treating PAD. Both conditions can worsen blood vessel damage and increase the risk of complications.

1. Diabetes: Good blood sugar control through diet, exercise, and medication can prevent further damage to the blood vessels.
2. Hypertension: Keeping blood pressure within normal limits with medication and a healthy lifestyle helps reduce the strain on the arteries.

With a combination of non-invasive treatment, medical procedures when needed, and management of coexisting conditions, PAD can be managed well. These steps not only reduce symptoms but also improve the quality of life of people with PAD. If you have been diagnosed with PAD, consult your doctor to plan the treatment that is most suitable for your condition.

How to Prevent Peripheral Artery Disease

Preventing peripheral vascular disease, or peripheral artery disease (PAD), starts with adopting a healthy lifestyle and reducing the risk factors that can trigger this condition. Here are some preventive steps you can take:

1. Quit smoking: Smoking is a major risk factor for peripheral artery disease. Quitting smoking can significantly reduce the risk of blood vessel damage.
2. Regular exercise: Physical activity such as walking, cycling, or swimming helps improve blood circulation and keep the blood vessels healthy.
3. Healthy diet: Eat foods that are low in saturated fat, high in fiber, and rich in fruits and vegetables. Avoid foods high in salt and sugar to keep your blood pressure and cholesterol levels stable.
4. Weight control: Maintaining an ideal body weight reduces the strain on the circulatory system and lowers the risk of PAD.
5. Manage coexisting conditions: If you have diabetes, hypertension, or high cholesterol, make sure these conditions are well controlled through medication and a healthy lifestyle.

By following these tips, you not only reduce your risk of PAD but also improve your overall health.

The Importance of Regular Health Check-Ups

Regular health check-ups are very important, especially for people with risk factors such as being over 50 years old, a history of smoking, diabetes, or cardiovascular disease. Regular check-ups help detect health problems early, including signs of PAD, before serious symptoms appear.

By having regular health check-ups, you can take more effective preventive steps and keep your blood vessels healthy. Remember, prevention is always better than cure!
