What is Angina?
Angina is a type of chest pain caused by reduced blood flow to the heart muscles. It occurs when the coronary arteries, which supply blood to the heart, become narrowed or blocked due to a build-up of fatty deposits. Angina is often a symptom of coronary artery disease and can be triggered by physical exertion, stress, or even heavy meals. It typically presents as a pressure or squeezing sensation in the chest but can also manifest as pain in the shoulders, arms, neck, jaw, or back.
Types of Angina
There are several types of angina:
- Stable Angina: This is the most common type and occurs during physical activity or stress. It usually lasts a few minutes and is relieved by rest or medication.
- Unstable Angina: This type is more severe and can occur at rest. It may last longer and require immediate medical attention as it can precede a heart attack.
- Variant (Prinzmetal's) Angina: Caused by a spasm in the coronary arteries, this type of angina often occurs at rest and can be quite severe.
How is Angina Treated?
The treatment for angina aims to reduce symptoms and prevent heart attacks and other complications. Common treatments include:
- Lifestyle Changes: Doctors may recommend adopting a healthier diet, engaging in regular exercise, quitting smoking, and managing stress levels.
- Medication: Several types of medications can help manage angina, including nitrates (to ease chest pain), beta-blockers, calcium channel blockers, aspirin, and statins to lower cholesterol.
- Surgery: In severe cases, procedures like angioplasty (to open blocked arteries) or coronary artery bypass surgery (to bypass blocked arteries) may be necessary.
It is essential for individuals experiencing symptoms of angina to consult their healthcare provider for an accurate diagnosis and tailored treatment plan. Managing risk factors and adhering to prescribed treatments can significantly improve quality of life and reduce the risk of severe cardiac events.
Where to Seek Help in the UK
In the United Kingdom, individuals with angina can seek help from the National Health Service (NHS) which provides extensive resources and support for heart conditions. Patients can start by consulting their GP (General Practitioner) for initial advice, diagnosis, and treatment. For emergencies, such as unstable angina or a heart attack, patients should call 999 for immediate assistance.

What are the types of angina?
The main types are stable angina, which follows a predictable pattern, and unstable angina, which is more unpredictable and serious.
How is angina diagnosed?
Diagnosis can involve a physical exam, electrocardiogram (ECG), stress tests, blood tests, and imaging studies like coronary angiography.
Can angina be cured?
While angina can't be cured, it can be managed effectively with lifestyle changes, medications, and sometimes surgery.
What lifestyle changes help manage angina?
Changes include quitting smoking, eating a healthy diet, exercising regularly, maintaining a healthy weight, and managing stress.
What medications are commonly used to treat angina?
Medications include nitrates, aspirin, beta-blockers, statins, calcium channel blockers, and antiplatelet drugs.
When should I seek emergency help for angina?
Seek immediate help if you experience chest pain that is new, worsening, or lasts longer than a few minutes, as it could indicate a heart attack.
Are surgical options available for treating angina?
Yes, procedures like angioplasty, where blocked arteries are opened, and coronary artery bypass surgery can improve blood flow to the heart.
How does stress contribute to angina?
Stress increases the heart's workload and blood pressure, which can trigger or worsen angina.
Is angina more common in a particular age group?
Angina is more common in older adults, especially those over 50, but can occur at any age if risk factors are present.
Can angina occur without chest pain?
Yes, it's called silent angina and can occur without noticeable symptoms, particularly in individuals with diabetes.
What is the prognosis for someone with angina?
With proper management, many people with angina can lead active, normal lives. However, it requires ongoing medical care to control the condition and prevent complications.
Can diet affect angina?
Yes, a heart-healthy diet rich in fruits, vegetables, whole grains, and low-fat proteins can help manage angina and improve heart health.
