Angina is chest pain or discomfort that occurs when the heart muscle doesn't get enough oxygen-rich blood. It often feels like pressure, squeezing, or burning in the chest. Common triggers include physical exertion, emotional stress, cold temperature, and heavy meals. While not a heart attack, angina is a warning sign of underlying coronary artery disease.
