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.

Physicians who specialize in cardiology are called cardiologists and they are responsible for the medical management of various heart diseases. Cardiac surgeons are the specialist physicians who perform surgical procedures to correct heart disorders
