What is angina?
By Dr Ananya Mandal, MD
Angina is a heart condition that is typically manifested as chest pain and is more of a symptom of an underlying condition than a disease in itself.
The pain in the chest is caused when the blood supply to the heart muscles of cardiac muscles falls short of the required amount. This occurs when the arteries that supply the heart become hardened and narrowed - a condition called arteriosclerosis.
