Cardiology

What is cardiology?

Cardiology is the study and treatment of disorders of the heart and the blood vessels. A person with heart disease or cardiovascular disease may be referred to a cardiologist.

Cardiology is a branch of internal medicine. A cardiologist is not the same as a cardiac surgeon. A cardiac surgeon opens the chest and performs heart surgery.

A cardiologist specializes in diagnosing and treating diseases of the cardiovascular system. The cardiologist will carry out tests, and they may some do procedures, such as heart catheterizations, angioplasty, or inserting a pacemaker.

Heart disease relates specifically to the heart, while cardiovascular disease affects the heart, the blood vessels, or both.
