angina day of procedure tips

Overview

Angina is chest pain or discomfort that happens when your heart muscle does not get enough oxygen-rich blood. It is often a symptom of coronary artery disease, where the arteries that supply blood to your heart become narrowed or blocked.

Yes, angina is common, especially in people over 50 and those with risk factors for heart disease. Many people with coronary artery disease experience angina at some point.

Angina mainly affects people with coronary artery disease. It is more common in older adults, men, and people with high blood pressure, high cholesterol, diabetes, or a family history of heart problems.

Symptoms

Common symptoms

• Chest pain or pressure that feels like squeezing, heaviness, or tightness
• Pain that may spread to the arms, neck, jaw, shoulder, or back
• Shortness of breath
• Nausea, fatigue, or dizziness

Symptoms in children

• Angina is rare in children. If it occurs, symptoms may include chest pain with exercise, tiredness, or fainting. Children with heart conditions like Kawasaki disease may be at higher risk.

Symptoms in older adults

• Older adults may feel less typical symptoms, such as shortness of breath, dizziness, or indigestion instead of clear chest pain. They might also confuse angina with other conditions.

Causes

Main causes

• Narrowing of the coronary arteries due to fatty deposits called plaque (atherosclerosis)
• Coronary artery spasm – a sudden tightening of the muscle in the artery wall

Risk factors

• High blood pressure
• High cholesterol levels
• Smoking or tobacco use
• Diabetes
• Obesity or being overweight
• Lack of physical activity
• Unhealthy diet high in saturated fat, salt, and sugar
• 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 any angina symptoms for the first time
• If your stable angina changes – becomes more frequent, severe, or happens at rest

Book a routine appointment if:

• If you have stable angina and your symptoms are well controlled, see your doctor for regular check-ups as advised (usually every 6 to 12 months).

Diagnosis

Your doctor will ask about your symptoms, medical history, and risk factors, then perform a physical exam. They may refer you to a heart specialist (cardiologist) for further tests.

Tests that may be done

• Electrocardiogram (ECG) – a quick test that records the electrical activity of your heart
• Blood tests – to check for markers of heart damage, cholesterol, and other risk factors
• Stress test – often done while walking on a treadmill to see how your heart responds to exercise
• Coronary angiography – a special X-ray using dye to look for blockages in the arteries

What to expect at your appointment

You may need to go to a hospital or clinic for tests. Some tests, like an ECG and blood tests, are quick and painless. A stress test may take about an hour. If you need an angiogram, it is usually done as a day procedure – you will be awake but given medicine to relax. Your doctor will explain everything before the test.

Treatment

Treatment for angina focuses on relieving symptoms, preventing heart attacks, and improving your quality of life. It includes lifestyle changes, medications, and sometimes procedures to restore blood flow.

Self-care at home

• Learn what triggers your angina (e.g., physical exertion, cold weather, heavy meals, stress) and try to avoid those triggers.
• Keep a symptom diary to share with your doctor.
• Take your medicines exactly as prescribed – do not stop without talking to your doctor.
• Carry your quick-relief angina medicine (such as a spray or tablets) with you at all times.
• On the day of a procedure, follow your doctor's instructions about eating, drinking, and which medicines to take. Do not skip your heart medicines unless told to.

Medical treatments

Doctors may prescribe medicines to widen blood vessels (nitrates for quick relief), slow the heart rate (beta-blockers), relax blood vessels (calcium channel blockers), or prevent blood clots (antiplatelet drugs). Your doctor will choose the best combination for your condition. Never take any new medicine without asking your doctor.

When is surgery considered?

If medicines and lifestyle changes are not enough, procedures like angioplasty (where a balloon opens a blocked artery, often with a stent) or coronary artery bypass surgery (where a healthy blood vessel is used to bypass the blockage) may be recommended. These are done in a hospital and can greatly improve blood flow to the heart.

Living with this condition

Living with angina means being aware of your limits and planning ahead. Learn to pace yourself during activities and take rest breaks. On the day of a procedure, follow your hospital's instructions carefully – for example, you may need to fast (not eat or drink) for a few hours beforehand. Bring a list of all your medicines and any allergies. Ask your doctor or nurse if you have any questions about the procedure.

Lifestyle tips

• Quit smoking – it is the single best thing you can do for your heart.
• Manage stress with relaxation techniques like deep breathing, meditation, or gentle hobbies.
• Get regular, gentle exercise after checking with your doctor – aim for at least 30 minutes of moderate activity most days.
• Maintain a healthy weight – even small weight loss helps.

Diet and exercise

Eat a heart-healthy diet low in saturated fat, salt, and added sugar. Fill your plate with fruits, vegetables, whole grains, and lean protein like fish or poultry. For exercise, start slowly with walking, swimming, or cycling. Your doctor may refer you to a cardiac rehabilitation programme that includes supervised exercise and education.

Mental health and emotional wellbeing

Angina can cause worry, anxiety, or depression because of the fear of a heart attack. It is normal to feel this way. Talk to your doctor about your feelings – they can offer support, counselling, or refer you to a mental health professional. You do not have to manage it alone.

Prevention

You cannot always prevent angina, but you can lower your risk by controlling blood pressure, cholesterol, and diabetes, eating well, staying active, and not smoking. These steps also slow the progression of artery narrowing.

Vaccines

There is no vaccine for angina, but getting recommended vaccinations (like the flu and pneumonia vaccines) can prevent illnesses that could make your heart condition worse. Ask your doctor which vaccines are right for you.

Screening programmes

Regular health check-ups that include blood pressure and cholesterol checks can catch risk factors early. If you have a strong family history of heart disease, your doctor may suggest earlier or more frequent screening.

Complications

If left untreated

• Heart attack (myocardial infarction) – when a blocked artery suddenly cuts off blood flow to part of the heart
• Heart failure – when the heart cannot pump blood effectively
• Irregular heart rhythms (arrhythmias) – which can be serious
• Sudden cardiac arrest – a life-threatening emergency

Long-term outlook

With proper treatment and lifestyle changes, most people with angina can lead full, active lives. Angina is a chronic condition that requires ongoing management, but the outlook is generally very good. Following your treatment plan and staying in touch with your doctor are the keys to preventing complications and maintaining a good quality of life.
