stress ultrasound explained
Informed by recognized medical guidance
Overview
A stress ultrasound, also called a stress echocardiogram, is a safe and painless test that looks at how your heart works when it beats faster and harder. It uses sound waves to create moving pictures of your heart, both while you are resting and while you exercise or receive medicine that makes your heart work harder.
Key facts
- It checks whether your heart muscle gets enough blood flow when it is under stress.
- It uses sound waves only, so there is no radiation exposure.
- It can help your doctor find narrowing or blockages in your heart arteries that might cause chest pain or shortness of breath.
Yes. Stress ultrasound is a common test used in hospitals and heart clinics around the world. Many people have it as part of the evaluation for chest pain, unusual breathlessness, or other heart-related concerns.
It can be used for adults who have symptoms that may be related to heart disease, including older adults. It can also be used for children and teenagers with certain heart conditions, but this is less common. Your doctor will only recommend it if there is a clear reason to check your heart under stress.
Symptoms
- Chest pain or pressure that lasts more than a few minutes, especially if it travels to your arm, neck, or jaw
- Sudden severe shortness of breath at rest
- Fainting or collapsing with no obvious cause
- A sudden rapid or irregular heartbeat with dizziness
- ⚠New or worsening chest pain that is not going away
- ⚠Chest pain that now happens with very light activity or at rest
- ⚠Increasing breathlessness over days or weeks
Common symptoms
- Chest pain, tightness, or pressure that comes on with activity and eases with rest
- Shortness of breath when you exercise or climb stairs
- Unexplained tiredness during physical activity
- A fast or irregular heartbeat feeling
Symptoms in children
- Chest pain or fainting during sports or exercise
- Shortness of breath or tiring quickly during physical activity compared with other children
Symptoms in older adults
- Feeling short of breath on mild exertion, such as walking to the shop
- Pain or discomfort in the chest, shoulders, arms, or jaw during activity
- Fatigue that is out of proportion to the level of exertion
Causes
Main causes
- A stress ultrasound is not caused by anything; it is a test. It is used to look for heart problems such as coronary artery disease, where a build-up of fatty material narrows the arteries that supply blood to the heart muscle.
- The symptoms that lead to a stress ultrasound can be caused by reduced blood flow to the heart, heart valve problems, or sometimes by conditions outside the heart.
Risk factors
- High blood pressure
- High cholesterol
- Smoking
- Diabetes
- A family history of early heart disease
- Being overweight or physically inactive
When to see a doctor
See a doctor urgently if:
- If you have chest pain that is new, worse, or happens at rest, see your doctor the same day or call your local healthcare service for advice.
- If you faint or have severe breathlessness with little activity, seek help promptly.
Book a routine appointment if:
- Make an appointment with your doctor if you have chest pain or breathlessness that comes on with exercise and goes away with rest.
- If you have risk factors for heart disease such as diabetes, high blood pressure, or high cholesterol, ask your doctor whether you might need a stress ultrasound as part of a check-up.
Diagnosis
A stress ultrasound is itself a diagnostic test, so it is not something you 'diagnose.' Your doctor will decide whether you need it based on your symptoms, medical history, and other tests. If it is ordered, you will go to a heart clinic or hospital where a trained technician and a doctor will be present.
Tests that may be done
- Resting electrocardiogram (ECG) to check your heart's electrical activity
- Blood tests to check for signs of heart strain or risk factors
- Exercise stress test on a treadmill or stationary bike
- Stress ultrasound with images taken before and after exercise or medicine
What to expect at your appointment
Before the test, you will be asked to avoid food and caffeine for a few hours. You will wear comfortable clothes and shoes. First, you will lie on a couch while a gel is applied to your chest and a small probe is moved over it. This gives resting pictures. Then you will exercise on a treadmill or bike, or receive a medicine through a small needle if you cannot exercise. Your heart rhythm, blood pressure, and pictures of your heart will be watched closely. After you finish, more heart pictures are taken. The whole test usually takes about 45 to 60 minutes.
Treatment
A stress ultrasound is a test, not a treatment. If it shows normal blood flow to your heart, you may not need any treatment at all. If it finds a problem, your doctor will talk with you about the best way to keep your heart healthy.
Self-care at home
- Follow the advice your doctor gives you about physical activity and rest.
- Stop smoking if you smoke, and limit alcohol.
- Keep any follow-up appointments so your doctor can review your test results with you.
Medical treatments
If stress ultrasound shows a heart problem, treatment aims to improve blood flow and reduce strain on the heart. This may include medicines to lower blood pressure, lower cholesterol, or help the heart pump more easily. It may also include lifestyle advice to eat healthily, move more, and manage stress. You and your doctor will decide together what is best for you.
When is surgery considered?
In some cases, if a blocked artery is severe, a procedure such as angioplasty (opening the artery with a small balloon) or bypass surgery (creating a new route for blood to flow) may be considered. Your doctor will explain the options and what to expect.
Living with this condition
After a stress ultrasound, you can usually return to your normal daily activities. If the results are normal, carry on with a healthy routine. If a heart condition is found, your doctor will give you a plan for managing it safely.
Lifestyle tips
- Aim for regular moderate activity, such as walking, after checking with your care team.
- Learn to recognise your body's warning signs, such as new chest pain or unusual breathlessness.
- Take time to relax and get enough sleep.
Diet and exercise
A heart-friendly diet includes plenty of vegetables, fruit, wholegrains, and lean protein. Try to limit salty foods, fried foods, and too much sugar. Exercise should be enjoyable and not cause symptoms. If you are unsure what is safe for you, ask your doctor or nurse.
Mental health and emotional wellbeing
Waiting for test results can feel worrying. It is normal to feel anxious or low while thinking about your heart health. Remember that a test is a step towards getting you the right care. Talk to your doctor or nurse about how you feel, and lean on family and friends for support.
Prevention
The test itself cannot prevent heart disease, but it helps detect problems early so they can be treated. Heart disease can often be prevented or slowed by a healthy lifestyle and by managing conditions like blood pressure, cholesterol, and diabetes.
Screening programmes
Some people at high risk for heart disease may be offered a stress ultrasound as part of a wellbeing check, even if they have no symptoms. Ask your doctor if you think you might benefit.
Complications
If left untreated
- If a heart condition found by a stress ultrasound is left untreated, reduced blood flow to the heart can lead to worsening chest pain, a heart attack, or heart failure.
- The test itself has very few risks. You may feel tired, breathless, or dizzy during the exercise, but these symptoms settle quickly.
Long-term outlook
The outlook for people who have a stress ultrasound is generally very positive. Whatever the result, it gives you and your doctor valuable information. If problems are found, modern treatments work well and many people with heart conditions live full, active lives.
