angina X ray explained

Overview

Angina is a type of chest pain or discomfort caused when your heart muscle doesn't get enough oxygen-rich blood. It is usually a symptom of coronary artery disease. A chest X-ray is sometimes used to help diagnose angina by looking at the size and shape of your heart and checking for other problems that could cause chest pain, such as lung conditions or fluid around the heart.

Yes, angina is very common. About one in 50 people in the UK experience angina at some point in their lives.

Angina most often affects adults over 50, but it can also occur in younger people, especially those with risk factors such as smoking, diabetes, high blood pressure, or a family history of heart disease.

Symptoms

Common symptoms

• Chest pain or discomfort that feels like pressure, squeezing, fullness, or sharp pain
• Pain spreading to the arms, shoulders, neck, jaw, or back
• Shortness of breath
• Fatigue or weakness
• Nausea or indigestion

Symptoms in children

• Angina is rare in children, but it can occur in those with congenital heart defects or conditions affecting the coronary arteries. Symptoms may include chest pain during exercise, difficulty feeding, or excessive sweating.

Symptoms in older adults

• Older adults may not feel typical chest pain. Instead, they might experience shortness of breath, extreme fatigue, confusion, or discomfort in the back, shoulders, or stomach.

Causes

Main causes

• Narrowing or blockage of the coronary arteries (the blood vessels that supply the heart) due to the buildup of fatty plaques (atherosclerosis)
• Spasm or tightening of the coronary artery muscle, which can reduce blood flow

Risk factors

• High blood pressure
• High cholesterol
• Smoking or exposure to second-hand smoke
• Diabetes
• Obesity or being overweight
• Lack of physical activity
• Unhealthy diet high in saturated fats, salt, and sugar
• Excessive alcohol consumption
• Stress
• Family history of heart disease
• Age (over 45 in men, over 55 in women)

When to see a doctor

See a doctor urgently if:

• If you have new chest pain or any chest pain that feels different from usual
• If your angina symptoms become more frequent, last longer, or happen with less activity
• If you have chest pain that does not improve with rest or with your prescribed medication

Book a routine appointment if:

• If you have risk factors for heart disease and want to discuss prevention
• If you have been diagnosed with angina and need a regular check-up
• If you experience mild, occasional chest pain that you haven't discussed with a doctor before

Diagnosis

Angina is diagnosed based on your symptoms, medical history, a physical exam, and several tests. A chest X-ray is often one of the first tests done because it can help rule out other conditions that cause chest pain, such as pneumonia, a collapsed lung, or an enlarged heart. However, a normal chest X-ray does not rule out angina.

Tests that may be done

• Chest X-ray – to check the size and shape of your heart and look for lung problems
• Electrocardiogram (ECG) – to record the electrical activity of your heart and detect any damage or irregular rhythms
• Blood tests – to check for markers of heart muscle damage, cholesterol, and blood sugar
• Stress test – to see how your heart works during physical activity
• Coronary angiography – a special X-ray with dye to see blockages in the heart arteries

What to expect at your appointment

A chest X-ray is quick and painless. You will stand or lie in front of the X-ray machine, and a technician will take one or two images while you hold your breath. The whole test takes about 10 minutes. You will need to remove any jewelry or metal objects from your chest area. Tell your doctor if you are pregnant or think you might be pregnant.

Treatment

Treatment for angina aims to relieve symptoms, reduce the risk of heart attack, and improve quality of life. It usually includes lifestyle changes, medications, and sometimes procedures. Your doctor will work with you to create a plan that fits your needs.

Self-care at home

• Stop smoking and avoid second-hand smoke
• Eat a heart-healthy diet low in saturated fat, salt, and added sugars
• Stay physically active as advised by your healthcare team
• Maintain a healthy weight
• Manage stress with relaxation techniques, hobbies, or support
• Limit alcohol to recommended amounts
• Keep track of your symptoms and know what triggers them

Medical treatments

Doctors may prescribe medications to widen blood vessels, reduce the heart's workload, or prevent blood clots. Common types include nitrates (to relieve chest pain quickly or prevent it), beta-blockers (to slow the heart rate and lower blood pressure), calcium channel blockers (to relax arteries), and antiplatelet drugs (to reduce clotting risk). Always take medications exactly as prescribed and discuss any side effects with your doctor.

When is surgery considered?

If lifestyle changes and medications do not control your symptoms, or if the arteries are severely blocked, your doctor may recommend a procedure such as angioplasty (inserting a small balloon to open the artery, often with a stent) or coronary artery bypass surgery (using a blood vessel from another part of your body to bypass the blockage). The decision is made on an individual basis.

Living with this condition

Living with angina means being aware of your symptoms, taking your medications regularly, and knowing when to seek help. Most people can continue their normal activities, but you may need to pace yourself and avoid sudden, strenuous exercise. Keep a record of your symptoms and share it with your doctor.

Lifestyle tips

• Avoid triggers such as heavy meals, extreme cold or heat, and emotional stress
• Carry your prescribed angina medication (like nitroglycerin spray or tablets) with you at all times
• Learn to recognize the warning signs of a heart attack
• Rest when you feel chest pain and take your medication as directed
• Ask your doctor about a cardiac rehabilitation program

Diet and exercise

Eat a diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats (like olive oil, nuts, and fish). Limit processed foods, sugary drinks, and red meat. Regular moderate exercise, such as walking, swimming, or cycling, can improve heart health and reduce angina attacks. Always check with your healthcare team before starting a new exercise routine.

Mental health and emotional wellbeing

Living with a chronic condition like angina can cause anxiety, stress, or depression. It is normal to worry about your health. Talk to your doctor about your feelings. They can refer you to a counsellor or support group. Many people find that staying active and connecting with others helps improve their mood.

Prevention

Angina cannot always be prevented, especially if you have a strong family history. However, you can lower your risk by making heart-healthy choices: not smoking, eating well, staying active, managing stress, and keeping blood pressure, cholesterol, and blood sugar under control. If you already have angina, these steps can help prevent it from getting worse.

Screening programmes

Routine screening for heart disease is not recommended for everyone, but if you have risk factors, your doctor may check your blood pressure, cholesterol, and blood sugar regularly. If you develop symptoms of angina, seek medical advice promptly. A chest X-ray is not used for screening, but it can be part of an evaluation if needed.

Complications

If left untreated

• Myocardial infarction (heart attack) – if a plaque ruptures and blocks blood flow completely
• Heart failure – if the heart muscle becomes weakened over time
• Arrhythmias (irregular heartbeats) that can be dangerous
• Sudden cardiac arrest (a medical emergency)

Long-term outlook

With proper treatment and lifestyle changes, most people with angina can manage their symptoms and live a long, active life. The key is to follow your treatment plan, attend regular check-ups, and seek emergency care when needed. Angina is a warning signal, not a life sentence – many people continue to enjoy their favorite activities with careful management.
