Angina is a medical condition which is commonly caused by coronary heart disease (CHD). CHD used to be referred to as ischaemic heart disease and can affect both men and women. Coronary heart disease (CHD) is when your coronary arteries become narrowed by a gradual build-up of fatty material within their walls. These arteries supply your heart muscle with oxygen-rich blood.
What are the symptoms of angina?
It is confirmed that angina can feel like a heaviness or tightness in your chest which can also spread to your arms, neck, jaw, back or stomach. The description of the feeling and symptoms of angina do vary as some people say it is like a feeling of severe tightness whilst others say it is more of a dull ache. There are people who also describe a shortness of breath.
Anyone with angina who experience a change in their symptoms or believe their angina has got worse or more frequent then they should seek immediate medical advice from their doctor.
What causes angina?
Angina is usually caused by coronary heart disease. When the arteries that supply your heart muscle with blood and oxygen become narrowed, the blood supply to your heart muscle is restricted. This can cause the symptoms of angina.
Angina symptoms are often brought on by physical activity, an emotional upset, cold weather or after a meal. The episodes usually subside after a few minutes.
Are there any other caused of angina?
- Variant angina (also referred to as Coronary artery spasm or Prinzmetal’s angina) which occurs when a coronary artery that supplies blood and oxygen to your heart goes into spasm.
- Microvascular angina (sometimes known as cardiac syndrome X) normally occurs when you are exerting yourself or have had an emotional upset. With microvascular angina the coronary arteries appear normal when investigated and this leaves no evidence of the fatty build-up in the arteries that would usually cause angina to occur.
