angina after diagnosis
Informed by recognized medical guidance
Overview
Angina is chest pain or discomfort that happens when the heart muscle does not get enough blood and oxygen. After a diagnosis, it means you and your healthcare team know the cause, usually narrowed or hardened arteries, and can put a plan in place to manage it and protect your heart.
Key facts
- Angina is a symptom of an underlying heart condition, not a disease on its own.
- It is usually triggered by physical activity, stress, or cold weather, and often improves with rest.
- With the right treatment and lifestyle changes, many people with angina live active, full lives.
Yes, angina is common. Many people around the world live with this condition. It is most often linked to coronary heart disease, which affects millions of people.
Angina mainly affects adults, especially those over 50. It is more likely in people who smoke, have high blood pressure, diabetes, high cholesterol, or a family history of heart disease. Men are affected somewhat more often than women, though women can also experience angina, sometimes with different symptoms.
Symptoms
- Chest pain that does not go away with rest or your usual prescribed angina medicine, or lasts more than 5 minutes
- Chest pain with sweating, nausea, vomiting, or severe shortness of breath
- Pain spreading to the left arm, both arms, neck, jaw, or back
- A feeling of pressure or tightness that keeps getting worse
- Loss of consciousness or collapse
- ⚠Your angina attacks are becoming more frequent, stronger, or lasting longer
- ⚠Your angina happens at rest or wakes you from sleep
- ⚠Your usual angina medicine does not work as well as it did before
- ⚠You feel breathless or more tired than usual with your normal activities
Common symptoms
- Chest pain or discomfort, often described as pressure, squeezing, heaviness, or tightness
- Pain that may spread to the shoulders, arms, neck, jaw, or back
- Shortness of breath
- A feeling of indigestion or heartburn
- Dizziness or fatigue during episodes
Symptoms in children
- Angina is rare in children. When it does occur, it is usually linked to a congenital heart condition or a problem with the coronary arteries. A child may complain of chest pain during exercise, feel unusually tired, or seem less active than usual.
Symptoms in older adults
- In older adults, angina may feel less like classic chest pain and more like breathlessness, fatigue, weakness, or simply a 'unwell' feeling. Pain may be felt in the back, shoulders, or upper abdomen rather than the chest.
Causes
Main causes
- A narrowing of the coronary arteries due to fatty deposits, a process called atherosclerosis
- A spasm in a coronary artery that temporarily reduces blood flow
- Increased workload on the heart, such as during exercise, stress, or a very fast heartbeat
Risk factors
- Smoking
- High blood pressure
- High cholesterol
- Diabetes
- Being overweight or obese
- Lack of physical activity
- Family history of heart disease
- Unhealthy diet high in saturated fat, salt, and processed foods
- Stress and anxiety
When to see a doctor
See a doctor urgently if:
- If you notice a sudden change in your angina pattern, such as attacks that happen more often, are more severe, or occur at rest, seek medical advice on the same day. If it is very severe or does not settle, call your local emergency number.
Book a routine appointment if:
- Attend all follow-up appointments with your doctor or cardiologist.
- If you have side effects from your medicines, or if you have questions about your treatment, make a routine appointment.
- If you are having difficulty making lifestyle changes, ask for a referral to a cardiac rehabilitation programme.
Diagnosis
Your diagnosis of angina is based on your symptoms, a physical examination, and tests that look at how well your heart and blood vessels are working. Since you have already been diagnosed, your doctor may use regular check-ups to adjust your treatment based on how you feel.
Tests that may be done
- Electrocardiogram (ECG) to record the heart's electrical activity
- Blood tests to check cholesterol, blood sugar, and signs of heart strain
- Stress test (exercise ECG) to see how your heart reacts to activity
- Coronary angiogram to look at the inside of your coronary arteries
- Echocardiogram to check the structure and pumping function of your heart
What to expect at your appointment
After a diagnosis, your healthcare team will explain your treatment plan, including medicines, lifestyle changes, and what to do if symptoms worsen. You will likely have regular follow-up appointments to monitor your condition and adjust your care as needed. You may also be offered cardiac rehabilitation, which is a structured programme of education and exercise tailored to you.
Treatment
Treatment for angina has two main goals: to prevent or reduce chest pain attacks, and to slow the narrowing of your arteries to lower your risk of a heart attack. A combination of medicines, healthy lifestyle changes, and sometimes procedures or surgery can help achieve both.
Self-care at home
- Rest or slow down when you feel an angina attack starting
- Always carry your fast-acting angina medicine as prescribed by your doctor
- Keep a record of your symptoms, what triggers them, and what helps
- Follow your treatment plan exactly and do not change medicines without asking your doctor
- Avoid heavy meals, sudden strenuous activity, and extreme cold or heat
Medical treatments
Your doctor may prescribe medicines to relax blood vessels, reduce blood pressure, lower cholesterol, or reduce the heart's workload so it needs less oxygen. Some medicines are taken regularly every day, while others are designed to be used quickly during an attack. Never take any new medicine, herbal remedy, or supplement without discussing it with your healthcare team, as some can affect your heart condition.
When is surgery considered?
If medicines and lifestyle changes are not enough to control your angina, your doctor may discuss procedures such as angioplasty with a stent (where a small balloon is inflated to open a narrowed artery and a mesh tube is left to keep it open) or coronary artery bypass surgery (where a healthy blood vessel is used to bypass a blocked artery). These are common and generally safe procedures, but the decision is made individually based on your situation.
Living with this condition
Learn to recognise your triggers and keep a daily symptom diary. Carry your prescribed medicines with you, and know what to do if an attack happens. Plan physical activities into your day, but avoid sudden bursts of effort. Always allow time to rest and pace yourself.
Lifestyle tips
- Stop smoking: this is one of the most important steps you can take.
- Limit alcohol intake.
- Maintain a healthy weight.
- Find healthy ways to manage stress, such as relaxation exercises, hobbies, or talking to friends.
- Get good quality sleep.
- Keep your blood pressure and cholesterol in a healthy range with your doctor's help.
Diet and exercise
Eat a heart-healthy diet rich in fruit, vegetables, whole grains, legumes, nuts, and oily fish. Choose lean meats and low-fat dairy, and cut down on saturated fats, salt, and added sugars. For exercise, aim for regular moderate activity such as walking, cycling, or swimming on most days of the week. Always check with your doctor before starting a new exercise programme, and build up gradually.
Mental health and emotional wellbeing
It is completely normal to feel anxious, stressed, or low after a heart diagnosis. Fear of another attack or a heart attack can be overwhelming at times. Talk to your doctor or a counsellor about these feelings. Cardiac rehabilitation often includes support for mental and emotional wellbeing. You may also find it helpful to join a support group where you can talk with others who understand what you are going through.
Prevention
You cannot always undo the hardening of arteries that has already happened, but you can slow the progression and prevent angina from getting worse. Managing blood pressure, cholesterol, and diabetes, along with lifestyle changes, and taking your prescribed medicines as directed, can make a big difference.
Vaccines
Annual flu vaccines and COVID-19 vaccines are recommended for people with heart conditions, as infections can put extra strain on your heart. Ask your doctor or pharmacist about vaccinations that are right for you.
Screening programmes
Regular check-ups to measure your blood pressure, cholesterol, and other heart risk factors are important. Your doctor will tell you how often you need these checks based on your condition.
Complications
If left untreated
- Heart attack, which can cause lasting damage to the heart muscle
- Heart failure, where the heart cannot pump blood well enough to meet the body's needs
- Abnormal heart rhythms, which may be dangerous
- Sudden cardiac arrest, which is a life-threatening emergency
Long-term outlook
The outlook for most people with angina is good, especially when the condition is managed well. With the right medicines, a healthy lifestyle, and regular follow-up, symptoms can often be controlled for many years and the risk of serious complications can be greatly reduced. Many people continue to work, travel, and enjoy active lives. Remember that you are not alone, and your healthcare team is there to support you at every step.
