questions to ask before angina

Overview

Angina is chest pain or discomfort that happens when your heart muscle doesn't get enough blood and oxygen. It is a symptom of coronary heart disease, not a disease itself. Think of it as a warning sign that your heart needs more blood.

Angina is a common symptom, affecting over 2 million people in the UK alone. It becomes more common as people get older.

Angina mainly affects adults over 50, but it can happen at any age, especially in people with risk factors like smoking, high blood pressure, diabetes, or a family history of heart disease.

Symptoms

Common symptoms

• Chest pain or discomfort that feels like squeezing, pressure, or heaviness
• Pain that spreads to the arms, neck, jaw, shoulders, or back
• Shortness of breath
• Feeling tired or weak during activity

Symptoms in children

• Angina is very rare in children. If a child has chest pain, it is usually from other causes, such as asthma, anxiety, or muscle strain. Any chest pain in a child should be checked by a doctor.

Symptoms in older adults

• Older adults may not feel typical chest pain. They might instead feel shortness of breath, fatigue, or just a feeling of being unwell.
• Pain may be felt in the shoulders, arms, or back more than the chest.

Causes

Main causes

• Narrowing or blockage of the coronary arteries due to a build-up of fatty deposits (atherosclerosis)
• Spasm of the coronary artery (less common, called variant or Prinzmetal's angina)
• Increased demand for oxygen by the heart, such as during exercise or stress, when the arteries cannot supply enough blood

Risk factors

• Smoking or using tobacco
• High blood pressure (hypertension)
• High cholesterol
• Diabetes
• Being overweight or obese
• Lack of physical activity
• Unhealthy diet high in saturated fats and salt
• Family history of heart disease
• Older age (over 45 for men, over 55 for women)

When to see a doctor

See a doctor urgently if:

• If you have new chest pain or chest pain that is getting worse, see a doctor as soon as possible.
• If you have had a heart attack or have known heart disease and your angina pattern changes (more frequent, more severe, or happens at rest), call for emergency help.

Book a routine appointment if:

• If you have been diagnosed with stable angina and you have questions about your condition, such as what activities are safe or how to manage triggers, talk to your doctor during a scheduled visit.
• If you are starting a new exercise program or need advice on medications (but never change or stop medications without talking to your doctor).

Diagnosis

Your doctor will take a detailed history of your symptoms, do a physical exam, and may order several tests to check how well your heart is working and whether your arteries are narrowed.

Tests that may be done

• Electrocardiogram (ECG or EKG) – records the electrical activity of your heart
• Blood tests – check for enzymes that suggest heart muscle damage, and check cholesterol and blood sugar
• Exercise stress test – walking on a treadmill while your heart is monitored
• Echocardiogram – ultrasound to see heart structure and function
• Coronary angiography – a dye test to see blockages in arteries (done in hospital)

What to expect at your appointment

You may be referred to a cardiologist (heart specialist). Tests can often be done as an outpatient. Some tests, like angiography, may require a short hospital stay. Your doctor will explain the results and discuss treatment options with you.

Treatment

Treatment for angina aims to relieve symptoms, improve quality of life, and reduce your risk of heart attack and stroke.

Self-care at home

• Learn what triggers your angina (like exercise, cold, or stress) and try to avoid or manage those triggers.
• Rest or take your prescribed medication (if any) when you feel angina coming on.
• Eat a heart-healthy diet, exercise regularly, and stop smoking.
• Keep a diary of your symptoms to share with your doctor.

Medical treatments

Doctors often prescribe medications to help widen blood vessels, lower blood pressure, or control cholesterol. They may also recommend a daily low-dose aspirin or other blood-thinning medicine. Always take medications exactly as prescribed and never stop without your doctor's advice.

When is surgery considered?

If medications and lifestyle changes are not enough, you may need a procedure such as angioplasty (using a balloon to open a blocked artery) or coronary artery bypass grafting (a surgical bypass). Your doctor will discuss the risks and benefits if surgery is an option for you.

Living with this condition

With proper treatment, most people with angina can do their usual daily activities. Keep a symptom diary, carry your medication with you, and know when to rest. Tell your family and friends about your condition so they can help in an emergency.

Lifestyle tips

• Stop smoking – it is the single best thing you can do for your heart.
• Manage stress through relaxation techniques, talking to someone, or hobbies.
• Get enough sleep – aim for 7–9 hours per night.
• If you drink alcohol, stick to recommended limits (no more than 14 units per week with some alcohol-free days).

Diet and exercise

Eat a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit salt, sugar, and saturated fats. Ask your doctor or a dietitian for a heart-healthy eating plan. Gentle exercise like walking is safe for most people, but always check with your doctor before starting a new exercise routine.

Mental health and emotional wellbeing

Living with a heart condition can cause anxiety, worry, or depression. It is normal to feel this way. Talk to your doctor about your feelings – they can refer you to a counsellor or support group. Remember, managing your mental health is part of managing your heart health.

Prevention

You cannot always prevent angina, but you can lower your risk by controlling risk factors. Healthy habits like not smoking, eating well, staying active, and managing blood pressure and diabetes can help prevent angina from getting worse.

Screening programmes

Routine screening for high blood pressure, high cholesterol, and diabetes can help catch problems early. If you have a strong family history of heart disease, talk to your doctor about earlier testing.

Complications

If left untreated

• Heart attack (myocardial infarction)
• Heart failure – when the heart cannot pump blood well
• Arrhythmias – irregular heartbeats that can be dangerous
• Sudden cardiac arrest

Long-term outlook

With the right treatment and lifestyle changes, most people with angina can manage their symptoms well and reduce their risk of serious heart problems. Angina is a condition you can live with for many years. Work closely with your healthcare team to stay as healthy as possible.
