Angina occurs when the heart does not receive sufficient oxygen due to narrowing of the arteries that carry blood to the heart. Not a condition on its own, angina is a symptom that indicates other, potentially serious, health issues including blocked arteries and heart disease.
The best-known symptom of angina is a pain in or around the chest. Some people describe the pain as a pressure or squeezing in the chest or surrounding areas. Pain levels can vary depending on age, physical condition, and other individual factors. Sometimes, the pain spreads to other parts of the body, including the neck, arms, or jaw. Chest pain may also be a symptom of a heart attack.
