Angina: Definition and Harmful Effects
Angina is a type of chest pain caused by reduced blood flow to the heart. It is usually a symptom of coronary artery disease (CAD), a condition in which the arteries that supply blood to the heart become narrow and hardened. Angina can also be caused by spasms of the coronary arteries.
Angina is usually felt as a squeezing, aching, or pressure-like sensation in the chest, usually in the center or left side of the chest. The pain may also radiate to the neck, jaw, arms, and back. It often occurs with physical exertion and is relieved with rest.
Although angina is not typically life-threatening, it is a sign of an underlying heart condition that may be dangerous. If left untreated, CAD can lead to a heart attack, heart failure, or death. It is important to receive medical care for angina to prevent further complications. Treatment options may include lifestyle changes, medications, or surgery.
