artery specialist tests overview

Overview

Artery specialist tests are medical procedures that check how well your arteries are working. Arteries are the blood vessels that carry oxygen-rich blood from your heart to the rest of your body. These tests help find blockages, narrowing, or other problems that could reduce blood flow.

Yes, these tests are very common. Many people have them as part of a check-up for heart or blood vessel health, especially if they have risk factors like high blood pressure or diabetes.

Artery specialist tests are for anyone with symptoms of artery disease, such as leg pain when walking, chest discomfort, or a family history of heart problems. They are also used in people with conditions like high cholesterol, diabetes, or who smoke.

Symptoms

Common symptoms

• Chest pain or discomfort (angina)
• Leg pain or cramping when walking (claudication)
• Shortness of breath
• Dizziness or feeling faint

Symptoms in children

• Rare, but can include high blood pressure or weak pulses in arms or legs
• Poor growth or fatigue during exercise

Symptoms in older adults

• Increased leg pain at rest or with walking
• Slow-healing sores or wounds on feet or legs
• Coldness or numbness in limbs

Causes

Main causes

• Atherosclerosis – a buildup of fatty deposits (plaque) inside the artery walls
• Blood clots that block an artery
• Inflammation of the artery walls (vasculitis)

Risk factors

• High blood pressure
• High cholesterol
• Smoking or tobacco use
• Diabetes
• Being overweight or obese
• Not being physically active
• Family history of heart or artery disease

When to see a doctor

See a doctor urgently if:

• You have chest pain that does not go away after a few minutes or happens at rest
• You suddenly lose feeling or movement in a limb
• You have a leg that becomes pale, cold, or painful for no reason

Book a routine appointment if:

• You have leg pain or cramping when walking that goes away with rest
• You have high blood pressure or diabetes and have not had artery tests recently
• You have a family history of early heart attacks or strokes and want to check your risk

Diagnosis

Your doctor will start by asking about your symptoms, medical history, and lifestyle. They will check your pulse and blood pressure in your arms and legs. Then they may recommend one or more special tests to look at your arteries.

Tests that may be done

• Ankle-Brachial Index (ABI): A quick test that compares blood pressure in your ankle with your arm. It helps find blockages in leg arteries.
• Doppler ultrasound: Uses sound waves to create images of blood flow in your arteries.
• CT angiogram: A special X-ray that uses dye to see your arteries clearly.
• Magnetic Resonance Angiogram (MRA): Uses magnets and radio waves to get detailed pictures of your blood vessels.
• Angiogram: A thin tube (catheter) is inserted into an artery, dye is injected, and X-rays are taken to see blockages.

What to expect at your appointment

Most artery tests do not require staying overnight. For some, you may need to avoid eating or drinking for a few hours before. The doctor or nurse will explain each step. You may feel a pinch or warmth when dye is used. Let your doctor know if you have any allergies or kidney problems.

Treatment

Treatment for artery problems focuses on improving blood flow and preventing further damage. It often starts with healthy lifestyle changes and medicines. If blockages are severe, procedures may be needed to open the artery.

Self-care at home

• Stop smoking – this is one of the most important steps you can take.
• Eat a heart-healthy diet with plenty of fruits, vegetables, and whole grains.
• Get regular exercise – walking is often a great start, but check with your doctor first.
• Manage stress with relaxation techniques or talking to a counselor.

Medical treatments

Your doctor may prescribe medicines to lower blood pressure, reduce cholesterol, or prevent blood clots. These are taken regularly and help keep your arteries open. Always take them exactly as prescribed. Do not start or stop any medicine without talking to your doctor.

When is surgery considered?

If blockages are severe and causing symptoms that do not improve with other treatments, procedures like angioplasty (opening the artery with a small balloon) or bypass surgery (creating a new route for blood flow) may be needed. Your doctor will discuss these options if they are right for you.

Living with this condition

Living with artery disease means paying attention to your body and staying on top of your health. Take your medicines as prescribed, follow up with your doctor regularly, and watch for any new or worsening symptoms.

Lifestyle tips

• Stay active – aim for 30 minutes of moderate activity most days, as advised by your doctor.
• Eat a balanced diet low in salt, sugar, and unhealthy fats.
• Keep a healthy weight.
• Avoid smoking and limit alcohol.

Diet and exercise

A diet rich in fruits, vegetables, whole grains, and lean proteins can help keep your arteries healthy. Avoid processed foods and too much red meat. Walking is a safe exercise for many – start slowly and build up. Your doctor or a physical therapist can give you a personalised plan.

Mental health and emotional wellbeing

Living with a chronic condition can be stressful. You may feel anxious or down about your health. It is okay to ask for help – talk to your doctor, a counsellor, or a support group. Managing your mental health is just as important as your physical health.

Prevention

You cannot prevent all artery problems, especially if you have a strong family history. But you can lower your risk by not smoking, eating well, staying active, and keeping your blood pressure, cholesterol, and diabetes under control.

Vaccines

None specifically for artery disease, but staying up to date with flu and pneumonia vaccines can help avoid infections that might stress your heart and arteries.

Screening programmes

If you have high blood pressure, diabetes, or other risk factors, your doctor may suggest regular checks of your blood pressure and cholesterol. Some people may also benefit from an ankle-brachial index test or ultrasound.

Complications

If left untreated

• Heart attack or stroke
• Peripheral artery disease causing leg pain and possibly limb loss
• Kidney damage from narrowed arteries to the kidneys
• Aneurysm – a bulging, weak spot in an artery that can burst

Long-term outlook

With early diagnosis and proper management, most people with artery problems can lead active, full lives. Treatment and lifestyle changes work well. Work with your healthcare team to stay on track – small steps make a big difference.
