screening for angina
Informed by recognized medical guidance
Overview
Angina is a type of chest pain or discomfort that happens when the heart muscle does not get enough oxygen-rich blood. It is usually a symptom of a heart problem, not a disease itself.
Key facts
- Angina is a warning sign that your heart may not be getting enough blood.
- Symptoms often happen during physical activity and get better with rest.
- Angina is not the same as a heart attack, but it can increase your risk of one.
Yes. Angina is very common, especially in people over 50 and those with heart disease risk factors.
It most often affects adults aged 50 and older. You are more likely to have it if you have high blood pressure, high cholesterol, diabetes, or a family history of heart disease. Smoking, being overweight, and not being active also increase your chances.
Symptoms
- Chest pain that lasts more than a few minutes or is severe
- Chest pain with shortness of breath, sweating, nausea, or lightheadedness
- Chest pain that spreads to your arms, neck, or jaw and does not go away with rest
- ⚠New or worsening chest pain that happens more often, at rest, or lasts longer than usual
- ⚠Chest pain that begins with a stressful event or after a long period of inactivity
Common symptoms
- Chest pain or pressure, often described as squeezing or heaviness
- Pain that spreads to your arms, neck, jaw, or back
- A feeling of tightness in the chest that comes on with activity, emotional stress, or cold weather
- Symptoms that usually stop after a few minutes of rest
Symptoms in children
- Angina is rare in children, but it can happen in children with certain heart conditions.
- Symptoms may include chest pain with exercise, trouble breathing, or unusual tiredness.
Symptoms in older adults
- Older adults may have less typical symptoms, such as shortness of breath, nausea, fatigue, or weakness.
- They may not feel obvious chest pain, so symptoms can be easy to miss.
Causes
Main causes
- Atherosclerosis: a buildup of fat and cholesterol in the coronary arteries, which narrows them and reduces blood flow
- Coronary artery spasm: when an artery temporarily tightens, cutting off blood flow
- Less commonly, heart disease caused by damage to the heart muscle or inflammation
Risk factors
- High blood pressure
- High cholesterol
- Smoking or exposure to secondhand smoke
- Diabetes
- Family history of early heart disease
- Being physically inactive
- Being overweight or obese
- Older age
When to see a doctor
See a doctor urgently if:
- If you have chest pain that is new, severe, or different from what you have felt before, call your local emergency number right away.
- If you have been diagnosed with angina and your symptoms happen more often, come on at rest, or last longer, seek care that day.
Book a routine appointment if:
- If you have any chest discomfort that worries you, even if it comes and goes, make an appointment with your doctor.
- If you have risk factors like diabetes, high blood pressure, or high cholesterol, talk to your doctor about regular heart checks.
Diagnosis
Doctors ask about your symptoms, medical history, and family history. They may do a physical exam and order tests to see how well your heart is working.
Tests that may be done
- Electrocardiogram (ECG or EKG): a quick test that measures your heart's electrical activity
- Blood tests: help look for substances that suggest your heart is stressed
- Exercise stress test: you walk or ride a stationary bike while your heart is monitored
- Imaging tests: such as an echocardiogram or a CT scan to see the structure and blood flow of your heart
- Coronary angiography: a special X-ray that shows blockages in the heart arteries
What to expect at your appointment
If your doctor suspects angina, they may refer you to a heart specialist. You might have tests on the same day or at a later visit. The process is usually not painful, though some tests involve needles or IVs. You will be guided through each step and told what to expect.
Treatment
Treatment for angina focuses on lowering your risk of a heart attack, reducing symptoms, and improving your quality of life. Your doctor will build a plan that is personal to you.
Self-care at home
- Rest when you feel chest discomfort.
- Learn what triggers your symptoms and avoid those situations when you can.
- Manage stress with relaxation techniques like deep breathing or mindfulness.
- Quit smoking if you smoke (ask your doctor for support).
- Have your blood pressure, cholesterol, and blood sugar checked regularly.
Medical treatments
Your doctor may prescribe medications to help widen your blood vessels, lower blood pressure, reduce cholesterol, or prevent blood clots. They may also recommend a low-dose medicine to help your heart work less hard. Always take medicines exactly as prescribed and talk to your doctor before stopping or changing any treatment. Some people may need a procedure such as angioplasty (opening a narrowed artery with a balloon) or heart bypass surgery if blockages are severe.
When is surgery considered?
Surgery is not the first step for most people. It is considered when medicines and lifestyle changes do not control symptoms, or when tests show severe blockages that put you at high risk.
Living with this condition
Living with angina means being aware of your body, carrying your medicines if prescribed, and knowing when to seek help. Many people live full, active lives by managing their condition and following a heart-healthy routine.
Lifestyle tips
- Follow a heart-healthy diet.
- Stay physically active with activities you enjoy, within your comfort level.
- Get enough sleep.
- Manage stress.
- Avoid smoking and excess alcohol.
- Keep regular appointments with your doctor.
Diet and exercise
Eat plenty of fruits, vegetables, whole grains, and lean proteins. Cut back on salt, saturated fat, and added sugars. Aim for at least 30 minutes of moderate exercise most days, but check with your doctor first. Start slowly and stop if you feel chest pain, shortness of breath, or very tired.
Mental health and emotional wellbeing
Angina can cause worry, stress, and low mood. You may feel anxious about having pain or fear of a heart attack. It is normal to feel this way. Talking to your doctor, a counsellor, or your family can help. Some people find relaxation exercises helpful.
Prevention
There is no guaranteed way to prevent angina, but you can reduce your risk by controlling your blood pressure, cholesterol, and weight, eating well, staying active, and not smoking. These habits also help prevent the underlying condition that causes angina.
Screening programmes
Screening for heart disease usually means checking blood pressure, cholesterol, and blood sugar. If you have symptoms or a family history, your doctor may recommend further tests. There is no simple 'angina test' for people without symptoms, but knowing your numbers helps you take action early.
Complications
If left untreated
- Heart attack
- Heart failure
- Irregular heartbeats (arrhythmias)
- Sudden cardiac arrest
Long-term outlook
With the right treatment, most people with angina can keep their symptoms under control and enjoy a good quality of life. Your outlook depends on your overall health, how well you stick to your plan, and how early you seek care. Many people live for many years after their first episode of angina.
