When to see a doctor
See a doctor urgently if:
- If you have new or worsening chest pain or fatigue
- If your angina attacks are more frequent, last longer, or feel more severe
- If you have trouble breathing or feel faint
Book a routine appointment if:
- If you have stable angina and want to talk about managing fatigue
- If you have risk factors for heart disease and are worried about your symptoms
Diagnosis
Your doctor will ask about your symptoms, medical history, and risk factors. They will listen to your heart and may order tests to check your heart function and blood flow.
Tests that may be done
- Electrocardiogram (ECG) to measure the heart's electrical activity
- Blood tests to check for heart damage or risk factors
- Exercise stress test to see how your heart handles activity
- Echocardiogram (ultrasound of the heart)
- Coronary angiography (special X-ray to look for blockages)
What to expect at your appointment
The diagnosis may take a few visits. Your doctor will explain each test and how to prepare. Many tests are non-invasive and painless.
Treatment
Treatment aims to relieve symptoms, prevent heart attacks, and improve your quality of life. It includes lifestyle changes, medicines, and sometimes procedures.
Self-care at home
- Rest when you feel tired or have angina
- Take your prescribed medicines exactly as your doctor tells you
- Learn what triggers your angina and try to avoid those triggers
- Keep a diary of your symptoms to share with your doctor
Medical treatments
Doctors may prescribe medicines to widen blood vessels, reduce the heart's workload, or prevent blood clots. Some people need procedures like angioplasty or bypass surgery to restore blood flow. Always follow your doctor's advice about medicines.
When is surgery considered?
Surgery, such as coronary artery bypass grafting, may be recommended if blockages are severe or if medicines do not control your symptoms.
Living with this condition
Living with angina and fatigue means pacing yourself. Listen to your body and take breaks when you need them. Plan activities for times when you have more energy. Keep a symptom diary to share with your doctor.
Lifestyle tips
- Eat a heart-healthy diet low in saturated fat and salt
- Stay physically active as much as you can, but don't push beyond your limits
- Quit smoking if you smoke
- Manage stress with relaxation techniques like deep breathing
- Maintain a healthy weight
Diet and exercise
A diet rich in fruits, vegetables, whole grains, and lean protein can help your heart. Talk to your doctor before starting any exercise program. Walking, gentle cycling, or swimming are often safe choices.
Mental health and emotional wellbeing
Feeling tired and having chest pain can be worrying and may lead to anxiety or depression. It is important to talk about your feelings with your healthcare team or a counsellor.
Prevention
You can lower your risk of developing angina or making it worse by adopting heart-healthy habits: not smoking, eating well, exercising regularly, controlling blood pressure and cholesterol, and managing diabetes.
Screening programmes
Regular check-ups and blood pressure monitoring can catch risk factors early. Talk to your doctor about your personal screening needs.
Complications
If left untreated
- Heart attack (myocardial infarction)
- Heart failure – when your heart cannot pump blood well
- Arrhythmias – irregular heartbeats
- Sudden cardiac arrest – when your heart stops beating
Long-term outlook
With proper treatment and lifestyle changes, most people with angina can manage their symptoms and lead active lives. Fatigue often improves with treatment. The key is to work closely with your healthcare team and follow your care plan.
