Cardiology

Cardiology is the branch of internal medicine dealing with disorders of the heart and blood vessels. The field is commonly divided in the branches of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.

What is Cardiology?

The term cardiology is derived from the Greek words “cardia,” which refers to the heart and “logy” meaning “study of.” Cardiology is a branch of medicine that concerns diseases and disorders of the heart, which may range from congenital defects through to acquired heart diseases such as coronary artery disease and congestive heart failure.
