I20-I25: Ischaemic heart diseases
I20: Angina pectoris
Angina pectoris, often simply called angina, is part of a group of conditions that generally affects the heart. It is caused by an inadequate flow of blood and oxygen to the heart itself, mainly due to blockages in the arteries that supply the heart. This narrowed or blocked supply route is often the result of hardening of the arteries (atherosclerosis), and triggers chest pain or discomfort known as angina. Angina sufferers might describe this pain as heaviness, tightness, pressure, or squeezing, usually located in the chest but, it can also spread to the neck, jaw or shoulders. It typically occurs with physical exertion or emotional stress but, in more severe cases, may come about even at rest or during sleep. Progression of this condition can lead to heart attack if left untreated. In addition to chest pain, symptoms of angina could also include shortness of breath, fatigue, and sweating.
