angina risk reduction
Informed by recognized medical guidance
Overview
Angina is chest pain or discomfort that happens when your heart muscle doesn't get enough oxygen-rich blood. It usually feels like pressure, squeezing, or heaviness in the chest. It can spread to your arms, jaw, or neck. It is a symptom of an underlying heart problem, often narrowed or blocked blood vessels.
Key facts
- Angina is a warning sign of heart disease, not a disease itself.
- It often occurs when the heart works harder, such as during exercise or stress.
- Reducing risk factors can prevent angina and help you live well.
Yes, angina is common. Many people with heart disease experience angina. It affects millions of people worldwide, often those over 50 or those with risk factors like smoking or diabetes.
Angina can affect anyone, but it is more common in older adults, men, and people with a family history of heart disease. People with certain health conditions like high blood pressure, diabetes, or high cholesterol are also at higher risk.
Symptoms
- Chest pain or pressure that lasts more than a few minutes or goes away and comes back
- Pain or discomfort in the chest along with symptoms like sweating, nausea, or light-headedness
- Pain spreading to the arm, jaw, neck, or back
- Sudden difficulty breathing or fainting
- Call your local emergency number right away if you have any of these symptoms.
- ⚠Chest pain that starts happening more often, lasts longer, or occurs at rest
- ⚠Pain that feels different or worse than your usual angina
- ⚠Angina symptoms that don't improve with rest or after taking your usual prescribed medicine as directed
Common symptoms
- Chest pain or discomfort that may feel like pressure, squeezing, or fullness
- Pain that spreads to the arms, jaw, neck, back, or stomach
- Shortness of breath
- Feeling tired or weak
- Sweating, nausea, or light-headedness
Symptoms in children
- Angina is rare in children. When it happens, it may be due to a heart problem present at birth. Symptoms can be similar, but children might not be able to describe their pain well. They may look pale, seem oddly tired, or clutch their chest.
Symptoms in older adults
- In older adults, angina may cause less typical symptoms, like shortness of breath, extreme fatigue, or pain only in the back, jaw, or shoulders. Sometimes symptoms happen without clear chest pain.
Causes
Main causes
- The most common cause is coronary artery disease, where fatty deposits (plaque) build up on the walls of the arteries that supply blood to the heart. This narrows the arteries and reduces blood flow. Activities that make the heart work harder, such as exercise, stress, or cold weather, can trigger symptoms.
Risk factors
- High blood pressure
- High LDL cholesterol (the 'bad' cholesterol)
- Smoking or using tobacco
- Diabetes
- Being overweight or obese
- Physical inactivity
- Unhealthy diet
- Family history of early heart disease
- Older age
When to see a doctor
See a doctor urgently if:
- Seek same-day care for worsening symptoms or a change in your usual pattern.
- If symptoms wake you from sleep or happen at rest, get medical help right away.
Book a routine appointment if:
- If you are new to angina symptoms, or have not been diagnosed, make an appointment to see your doctor.
- If you have risk factors and want to know your heart risk, talk to your healthcare team.
Diagnosis
Your doctor will ask about your symptoms, medical history, and risk factors. They will listen to your heart and may run tests to check how well your heart is working and whether blood flow is reduced.
Tests that may be done
- Electrocardiogram (ECG or EKG) to measure the heart's electrical activity
- Blood tests to check for substances that may indicate heart damage
- Stress tests to see how your heart responds to activity
- Imaging tests, like an echocardiogram or coronary angiogram, to look at heart structure and blood vessels
What to expect at your appointment
You may be asked to keep a record of your symptoms and when they happen. Your doctor may refer you to a heart specialist for further tests. Diagnosis is a process, and you will have time to discuss your results and next steps.
Treatment
Treatment for angina focuses on reducing symptoms and lowering the risk of heart attack and other complications. Your healthcare team will help you create a plan based on your situation. This includes lifestyle changes, medicines, and possibly procedures to restore blood flow.
Self-care at home
- Learn to recognise your triggers and get rest when symptoms start
- Quit smoking if you smoke, and avoid secondhand smoke
- Manage stress with breathing exercises, relaxation, or other calming activities
- Follow your doctor's advice about how much activity is safe for you
- Keep a symptom diary to share with your healthcare team
Medical treatments
Medicines can help reduce angina symptoms and prevent blood clots, lower blood pressure, and improve blood flow. Some medicines are taken regularly, while others are used during an episode. Your doctor will explain how and when to use them. Procedures such as balloon angioplasty or stenting may be considered when medicines and lifestyle changes are not enough. A doctor will discuss the best options for you.
When is surgery considered?
Surgery, such as coronary artery bypass grafting, may be recommended for people with severe blockages or when other treatments do not relieve symptoms. Your heart team will discuss whether this is right for you.
Living with this condition
Living with angina means learning to listen to your body. Plan your activities, take regular breaks, and avoid sudden intense exertion. Keep your medications with you if prescribed, and always carry your doctor's advice about what to do when symptoms occur.
Lifestyle tips
- Eat a heart-healthy diet rich in vegetables, fruits, whole grains, and lean protein
- Aim for a healthy weight and eat sensible portions
- Stay active with walking, cycling, or swimming, as recommended by your doctor
- Limit alcohol and avoid smoking
- Keep follow-up appointments with your healthcare team
Diet and exercise
A heart-healthy diet can help lower blood pressure and cholesterol. Include plenty of fibre, choose unsaturated fats over saturated and trans fats, and reduce salt. Exercise helps strengthen the heart and improves circulation. Your doctor can help you create a safe exercise plan, starting slowly and building up gradually.
Mental health and emotional wellbeing
Angina can cause anxiety, fear, or sadness. It is normal to feel worried after a diagnosis. Talking to a counsellor, joining a support group, or practising mindfulness can help. Remember that taking steps to manage your health can increase your sense of control and confidence.
Prevention
Yes, in many cases you can prevent angina by managing your risk factors. Even if you have heart disease, a healthy lifestyle and following your treatment plan can slow its progression and reduce symptoms.
Vaccines
Talk to your healthcare provider about getting vaccinated against flu, pneumococcal infection, and COVID-19. These infections can put extra stress on your heart. Vaccination can help protect your heart health.
Screening programmes
Regular health check-ups that include blood pressure, cholesterol, and blood sugar checks can detect problems early. Early detection allows you to make changes before heart disease develops or worsens.
Complications
If left untreated
- Heart attack, which can damage the heart muscle
- Heart failure, when the heart cannot pump blood well enough
- Irregular heart rhythms (arrhythmias)
- Sudden cardiac arrest, a life-threatening emergency
Long-term outlook
The outlook for angina is good if it is caught early and managed well. Many people continue to enjoy active, fulfilling lives. With the right treatment and a healthy lifestyle, you can significantly reduce your chances of a heart attack and improve your well-being.
