angina flare ups
Informed by recognized medical guidance
Overview
Angina is a type of chest pain or discomfort that happens when part of your heart isn't getting as much oxygen-rich blood as it needs. An angina flare-up is when your usual symptoms become more frequent, occur with less effort, last longer, or feel more intense.
Key facts
- Angina is a symptom of an underlying heart problem, not a disease on its own.
- A flare-up can be a warning sign that your heart disease is progressing.
- Learning your triggers and following your care plan can help you stay in control.
Yes. Angina is very common among people with coronary heart disease, especially as they get older.
Angina mainly affects people with narrowed or hardened arteries. You are more likely to experience it if you smoke, have high blood pressure, high cholesterol, diabetes, or a family history of heart disease. It is more common in men over 50 and women after menopause.
Symptoms
- Chest pain that lasts more than 5 minutes or doesn't go away when you rest
- Chest pain accompanied by a cold sweat, nausea, or light-headedness
- Pain spreading to your arm, jaw, shoulder, or back
- Sudden breathlessness, unexplained weakness, or collapse
- ⚠Symptoms that come on when you are resting or wake you from sleep
- ⚠Symptoms triggered by much less activity than usual
- ⚠Symptoms that feel stronger, last longer, or happen more often
- ⚠Your prescribed chest pain medication is not helping as well as it usually does
Common symptoms
- Chest pain, pressure, heaviness, or a squeezing feeling
- Pain that may spread to your left arm, neck, jaw, or back
- Shortness of breath
- Feeling tired or weak
- Nausea or indigestion
Causes
Main causes
- Coronary artery disease – narrowing of the heart arteries by fatty deposits called plaques
- Coronary artery spasm – a temporary tightening of a heart artery
- Increased demand on the heart during hard exercise, stress, cold weather, or heavy meals
Risk factors
- Smoking
- High blood pressure
- High cholesterol
- Diabetes
- Being overweight or inactive
- Family history of early heart disease
- Stress
- Older age
When to see a doctor
See a doctor urgently if:
- Go to your nearest emergency department or call your local emergency number if you have new, severe, or prolonged chest pain.
- Seek same-day medical help if your usual angina pattern changes – for example, it comes on at rest, wakes you from sleep, or your relief medicine isn't working.
- If you have a heart condition and you feel faint, very breathless, or have pain spreading to your arm or jaw, get urgent help.
Book a routine appointment if:
- If you have been diagnosed with angina and are planning to increase your exercise level
- If you have questions about your medicines or ways to lower your risk
- For regular reviews with your heart team to keep your treatment up to date
Diagnosis
A doctor will ask you about your symptoms, medical history, and lifestyle, and may order tests to look at how well your heart is working and whether your arteries are narrowed.
Tests that may be done
- Electrocardiogram (ECG) to record the heart's electrical activity
- Blood tests to check for signs of a heart attack or risk factors
- Exercise tolerance test (stress test) to see how your heart responds to activity
- Imaging tests such as a CT scan or ultrasound scan
- Coronary angiography – a special X-ray dye test to look for blockages
What to expect at your appointment
You'll usually be referred to a heart specialist for further assessment. Many tests are done as an outpatient, and you won't be admitted unless the team finds something that needs urgent treatment.
Treatment
The goal of treatment for angina flare-ups is to quickly control symptoms, reduce the chance of future flare-ups, and protect your heart from further damage. Treatment involves a combination of everyday self-care, medicines, and possibly procedures to restore blood flow.
Self-care at home
- Learn your trigger patterns and plan activities accordingly
- Stop what you're doing and rest if symptoms start
- Take your prescribed chest pain relief medicine as you've been shown
- Carry a list of your medicines and health conditions with you
- Get support to quit smoking and aim for a heart-healthy lifestyle
Medical treatments
Your doctor may prescribe medicines to relax and widen your blood vessels, lower your blood pressure or cholesterol, reduce the heart's workload, and prevent blood clots. Some of these are taken regularly to prevent angina, and one special medicine is used for quick relief during an attack. Always take medicines exactly as prescribed.
When is surgery considered?
If medicines and lifestyle changes aren't enough and a narrowed artery is found to be blocking blood flow, your doctor might discuss procedures such as inserting a tiny balloon and stent to open the artery, or bypass surgery to reroute blood around the blockage.
Living with this condition
Keep a simple symptom diary – write down when angina happens, what you were doing, and how long it lasted. This gives you and your health team useful clues for adjusting your care.
Lifestyle tips
- Quit smoking – it's one of the most powerful changes
- Attend cardiac rehabilitation if it's offered
- Keep up with regular appointments and take your medicines as prescribed
- Learn relaxation techniques that work for you
- Stay within the activity level recommended by your heart team
Diet and exercise
Follow a heart-friendly diet that is low in salt, saturated fat, and processed foods, and rich in vegetables, fruits, whole grains, and fish. For exercise, aim for regular, moderate activity – like brisk walking or cycling – but check with your doctor about what's safe for you. Many people find that spacing out exercise after meals works better.
Mental health and emotional wellbeing
Living with angina can make you feel anxious, low, or worried about another flare-up. These feelings are completely normal. Talk about them with someone you trust, and let your healthcare team know if you're struggling. If you ever feel desperate or have thoughts of harming yourself, contact your local crisis support service right away.
Prevention
You can lower your risk of flare-ups by carefully managing the conditions that cause angina, such as high blood pressure, high cholesterol, and diabetes. Staying active, eating well, and avoiding smoking are also key.
Vaccines
Stay up to date with annual flu vaccination and ask about pneumonia vaccination, since chest infections can put extra strain on your heart.
Screening programmes
Regular blood pressure, glucose, and cholesterol checks – especially if you have a family history of heart disease – can help catch problems early.
Complications
If left untreated
- Heart attack – when a blood clot completely blocks a heart artery
- Worsening of coronary artery disease
- Damage to the heart muscle over time, leading to heart failure
- Serious abnormal heart rhythms (arrhythmias)
Long-term outlook
The outlook for angina is good when it's discovered early and treated consistently. Many people live full, active lives by working closely with their healthcare team and taking their heart health seriously.
