How does angina cause fever?

Angina does not cause a fever. Fever is a symptom that is usually associated with an infection or other medical conditions, such as autoimmune diseases or certain types of cancer. Angina, on the other hand, is a type of chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. It is a symptom of coronary artery disease and is not typically associated with fever.
