artery flare ups

Overview

An artery flare-up is a temporary period when your artery symptoms get noticeably worse. It's not a disease itself, but a sign that an underlying problem with your arteries—such as narrowed or inflamed arteries—needs attention. Because arteries supply oxygen-rich blood to your whole body, a flare-up can affect your heart, legs, or brain, depending on which artery is involved.

Yes. Artery flare-ups are common in people who live with conditions that narrow or damage arteries, such as coronary artery disease, peripheral artery disease, or vasculitis.

They most often affect adults over 50 and people with risk factors like smoking, high blood pressure, high cholesterol, diabetes, or a family history of heart and circulation problems. They can also occur in younger people with certain inflammatory conditions.

Symptoms

Common symptoms

• Chest pain, pressure, tightness, or heaviness (often with physical activity)
• Shortness of breath
• Pain, cramping, heaviness, or tiredness in your legs that comes on with walking and eases with rest
• Pain in the shoulder, arm, jaw, or back
• Feeling unusually tired or dizzy

Symptoms in children

• Artery flare-ups are rare in children. When they do occur, they may cause fever, a rash, pale or cool arms and legs, or chest pain. If your child has any of these, contact a healthcare professional right away.

Symptoms in older adults

• Older adults may not feel typical chest pain. Instead, they may become suddenly breathless, confused, dizzy, or very tired. Leg symptoms, like pain or weakness when walking, can also be a sign.

Causes

Main causes

• Atherosclerosis: a build-up of fatty plaques that narrow and stiffen the arteries
• Inflammation of the artery wall (vasculitis)
• A blood clot that partially blocks an artery
• Spasm of the artery, causing it to squeeze shut temporarily

Risk factors

• Smoking or using tobacco
• High blood pressure
• High cholesterol
• Diabetes
• Being overweight or inactive
• Stress and anxiety
• Cold weather or sudden physical effort
• Having a family history of heart or artery disease

When to see a doctor

See a doctor urgently if:

• If you have new or worsening chest pains, or any symptoms that come on with less effort than before, contact your doctor or local same-day health service that day.
• If you have leg pain that comes and goes with walking and is getting noticeably worse, get a routine appointment soon.

Book a routine appointment if:

• Book a routine appointment if you have risk factors for artery disease and have never discussed them with a doctor.
• See your doctor regularly to monitor high blood pressure, high cholesterol, or diabetes.

Diagnosis

Your doctor will take a detailed history, examine you, and use your description of symptoms to decide which tests you need. Tests help see how well your arteries are working and whether any are narrowed.

Tests that may be done

• Blood tests to check cholesterol, blood sugar, and markers of inflammation
• Electrocardiogram (ECG) to check your heart's rhythm and electrical activity
• Ultrasound scanning of the legs or neck to look at blood flow in the arteries
• A stress test to see how your heart and arteries respond to physical effort
• Angiography or a CT scan to get detailed images of your arteries

What to expect at your appointment

Most tests are painless and many can be done in a day. You may be asked to stop eating before a blood test or to avoid exercising beforehand. Your doctor will explain each step and what they are looking for.

Treatment

Treatment has two goals: to ease symptoms during a flare-up and to stop future flare-ups by treating the underlying cause. This usually involves a heart-healthy lifestyle, medicines to manage risk factors, and in some cases a procedure to restore blood flow.

Self-care at home

• Stop what you are doing and rest if you feel chest pain or severe breathlessness.
• Follow your prescribed care plan and take any treatments exactly as directed.
• Keep warm, especially in cold weather.
• Avoid sudden heavy exertion.
• Tell your doctor about any pattern you notice—what triggers your flare-ups is helpful information.

Medical treatments

Depending on your specific situation, your healthcare team may offer medicines to relax blood vessels, reduce cholesterol, prevent blood clots, lower blood pressure, or control inflammation. They may also recommend a structured cardiac rehabilitation programme. Always ask your doctor or pharmacist for details about the medicines you are prescribed.

When is surgery considered?

If a test shows that an artery is severely narrowed or blocked, and medicines alone are not enough, a specialist may suggest a procedure such as putting in a small tube (stent) to keep the artery open, or bypass surgery to create a new route for blood to flow.

Living with this condition

Living with artery disease means learning to notice your warning signs and pacing yourself. Keep a record of your symptoms and what brings them on. Most people can still do the things they love by making adjustments with their healthcare team.

Lifestyle tips

• Quit smoking—your doctor or pharmacist can help you find a plan.
• Manage stress with relaxation exercises, breathing techniques, or talking to someone you trust.
• Aim for 7 to 9 hours of quality sleep each night.
• Keep your scheduled check-ups with your doctor.

Diet and exercise

A heart-friendly diet is full of vegetables, fruits, whole grains, lean proteins, and healthy fats, and low in salt, added sugar, and processed foods. For exercise, aim for regular moderate activity such as walking, swimming, or cycling, but always check with your doctor what level is safe for you—especially if any activity brings on symptoms.

Mental health and emotional wellbeing

Repeated flare-ups can feel frightening and stressful. This is completely understandable. Anxiety and low mood can themselves put extra strain on your heart and arteries, so it is important to talk about how you feel with your healthcare team and to ask about counselling or support groups if needed.

Prevention

Many artery flare-ups can be prevented by keeping your arteries as healthy as possible. Even with a family history, a heart-healthy lifestyle and good control of blood pressure, cholesterol, and diabetes can make a big difference.

Vaccines

Staying up to date on vaccines such as the flu vaccine can reduce your risk of infections that might stress the heart and trigger flare-ups. Ask your pharmacist or local clinic what is recommended for you.

Screening programmes

Regular checks of your blood pressure, cholesterol, and blood sugar are the best ways to catch problems early. If you have risk factors, your doctor may recommend more frequent screening based on your personal history.

Complications

If left untreated

• A heart attack if a coronary artery becomes fully blocked
• A stroke if an artery to the brain becomes blocked
• Severe leg pain, ulcers, or tissue damage if limb arteries are severely narrowed
• Weakening of the artery wall, which may lead to an aneurysm

Long-term outlook

With proper treatment and lifestyle changes, most people with artery disease can live long, active lives. Flare-ups often become less frequent and less severe once you understand your triggers and follow your care plan. There is always reason to be hopeful—modern treatments are very effective when started early.
