What is angina?

Angina is not a disease: it often is a symptom of a heart problem. The heart problem that most commonly leads to chronic angina is coronary heart disease (CHD).2 Angina is usually experienced as discomfort or pain in the chest or surrounding areas (arm, shoulder, back, neck or jaw), which occurs when the heart is not getting as much oxygen-rich blood as it needs.2,3 Click here to learn about angina.

What is coronary heart disease (CHD)?

In coronary heart disease, also known as coronary artery disease (CAD), the vessels that supply blood to your heart become stiff and narrow. This makes it difficult for oxygen-rich blood to reach your heart. Reduced blood flow that occurs following exercise or emotional stress leads to chest pain or discomfort known as chronic stable angina.2,3

What is the difference between angina and a heart attack?

An angina attack is not a heart attack. Angina means the heart is not getting enough oxygen for the moment.2,3 The pain does not mean the heart is damaged permanently. Angina does not usually cause permanent damage to the heart.

A heart attack happens when blood flow to the heart is suddenly cut off. This may cause permanent damage to the heart.5 Chest pain is usually more severe, lasts longer and does not go away with rest or nitroglycerin.

If you are experiencing angina that does not go away with rest or nitroglycerin, this could be a sign of unstable angina which is a serious condition that can lead to a heart attack.2,3 Patients experiencing unstable angina should seek immediate medical attention.*

How is angina diagnosed?

Angina is diagnosed by noting a patient's symptoms and how they arise. Your cardiologist may run tests to confirm the presence of angina and to establish the severity of the heart condition. Tests may include an electrocardiogram (ECG) at rest, a treadmill exercise test, a pharmacological stress test, and an angiogram (imaging of the coronary arteries using a heart catheter).2

How is angina treated?

There are a variety of approaches to chronic angina treatment. These include:2,13,14

  • Antianginal medications
  • Lifestyle changes
  • Angioplasty/Percutaneous coronary intervention (PCI, also known as stenting)
  • Bypass surgery
  • Cardiac rehabilitation

Your cardiologist may suggest a combination of these options, depending on your symptoms and medical history. The goal of treatment of chronic angina should be relief of angina symptoms and a return to normal physical activity levels.6 Click here to learn more about the treatments for angina.

Can angina treatment reduce my symptoms?


The goal of treatment of chronic angina is to:
