stress screening test preparation
Informed by recognized medical guidance
Overview
A stress screening test (also called an exercise stress test or treadmill test) is a way for doctors to check how well your heart works when it is under stress, such as during exercise. It can help find problems with blood flow to your heart muscle.
Key facts
- The test usually involves walking on a treadmill or riding a stationary bike while your heart rate, blood pressure, and heart rhythm are monitored.
- You may be asked to stop taking certain medicines or to avoid food, drink, or smoking before the test. Your doctor will give you specific instructions.
- The test is safe, but you should tell the medical team about any chest pain, feeling dizzy, or shortness of breath during the test.
- Results help your doctor decide if more tests or treatments are needed to keep your heart healthy.
Yes, stress screening tests are a common way to evaluate heart health, especially in people with symptoms like chest pain or in those at higher risk for heart disease.
Adults who have symptoms of heart disease (such as chest pain or shortness of breath), or who have risk factors for heart disease (such as high blood pressure, high cholesterol, diabetes, smoking, or a family history of heart problems).
Symptoms
- Chest pain that does not go away (especially if it feels like pressure or tightness)
- Severe difficulty breathing
- Fainting or near-fainting
- Pain spreading to your arms, back, neck, or jaw
- ⚠New or worsening chest pain or shortness of breath that is not severe
- ⚠Palpitations that happen often or last a long time
Common symptoms
- Chest pain or discomfort (angina)
- Shortness of breath during activity
- Fatigue or weakness
- Palpitations (feeling like your heart is racing or skipping beats)
Symptoms in children
- Stress tests are rarely performed in children; symptoms in children that might lead to a stress test include chest pain or fainting during exercise.
Symptoms in older adults
- Shortness of breath with mild activity
- Unexplained fatigue
- Dizziness or lightheadedness
- Less ability to do usual activities
Causes
Main causes
- Coronary artery disease (narrowing of the arteries that supply blood to your heart muscle)
- Heart valve problems
- Heart rhythm disorders
Risk factors
- High blood pressure
- High cholesterol
- Diabetes
- Smoking
- Being overweight or obese
- Lack of physical activity
- Unhealthy diet
- Family history of early heart disease
- Stress and anxiety
When to see a doctor
See a doctor urgently if:
- You have chest pain or discomfort that lasts more than a few minutes or goes away and comes back.
- You have severe shortness of breath, especially with activity.
- You faint or nearly faint.
Book a routine appointment if:
- You have mild chest pain or discomfort that happens with activity and gets better with rest.
- You are at high risk for heart disease (for example, if you have diabetes or a strong family history) and have not had a check-up recently.
- You are over 45 (men) or over 55 (women) and plan to start a vigorous exercise program.
Diagnosis
A stress screening test is usually done in a hospital or clinic. You will be asked to exercise on a treadmill or stationary bike while your heart is monitored. If you cannot exercise, you may be given a medicine that makes your heart work harder.
Tests that may be done
- Exercise stress test (treadmill or bike)
- Stress echocardiogram (ultrasound of the heart before and after exercise)
- Nuclear stress test (injection of a small amount of radioactive tracer to see blood flow to the heart)
What to expect at your appointment
Before the test, you will be asked to wear loose, comfortable clothing and shoes suitable for walking. Your weight, height, and blood pressure will be recorded. Sticky patches (electrodes) will be placed on your chest and sometimes your arms and legs. A blood pressure cuff will be on your arm. During the test, the exercise will start slowly and get harder. The team will watch your heart rate, blood pressure, and how you feel. The test usually lasts about 10–15 minutes. After the test, you will rest while your heart rate returns to normal.
Treatment
Treatment depends on the results of the stress test. If it shows a problem, your doctor may recommend lifestyle changes, medicines, or procedures to improve blood flow to your heart. If the test is normal, you may only need to keep up your healthy habits.
Self-care at home
- Eat a balanced diet low in saturated fats, salt, and added sugars.
- Get regular physical activity, like walking or swimming, for at least 30 minutes most days.
- Manage stress with relaxation techniques, hobbies, or talking to a friend or counsellor.
- Avoid smoking and limit alcohol.
- Take all medicines exactly as prescribed by your doctor.
Medical treatments
If the stress test shows blockages or heart muscle problems, doctors may suggest medicines to lower blood pressure, reduce cholesterol, or prevent blood clots. In some cases, a procedure called angioplasty (to open narrowed arteries) or bypass surgery may be needed. Your doctor will discuss the best options for you.
When is surgery considered?
Surgery, such as coronary artery bypass grafting, may be considered if there are severe blockages or if other treatments haven't helped.
Living with this condition
After a stress test, you can usually return to your normal activities. If your test shows heart disease, you may need to make changes to protect your heart, such as taking more rest during activities and following a heart-healthy routine.
Lifestyle tips
- Follow a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins.
- Stay active, but talk to your doctor about what level of exercise is safe for you.
- Keep a healthy weight.
- Get enough sleep (7–9 hours per night).
- Avoid smoking and second-hand smoke.
Diet and exercise
Eat plenty of fibre, omega-3 fatty acids (found in fish like salmon), and limit processed foods. Exercise can be walking, cycling, or swimming. Always warm up and cool down. Ask your doctor before starting any new exercise program.
Mental health and emotional wellbeing
Worrying about your heart can cause stress and anxiety. It is normal to feel concerned. Talking to your doctor, family, or a mental health professional can help. You are not alone.
Prevention
You can reduce your risk of heart disease by making healthy choices, such as not smoking, eating well, exercising, and managing stress. Regular check-ups with your doctor can catch problems early.
Vaccines
Get recommended vaccines, including the flu vaccine and COVID-19 vaccine, as infections can put extra stress on the heart.
Screening programmes
Screening for heart disease may include checking blood pressure, cholesterol, and blood sugar. Your doctor might recommend a stress test if you have symptoms or high risk.
Complications
If left untreated
- Heart attack
- Heart failure (your heart cannot pump blood well)
- Arrhythmia (irregular heartbeat)
- Stroke
Long-term outlook
Most heart disease can be managed well with the right treatment and lifestyle changes. A stress test helps your doctor find problems early, so you can take action. Many people with treated heart disease live full, active lives.
