## Definition

the branch of medicine that deals with the heart and its diseases. Doctors in this field study how the heart works and how to fix problems with blood flow.

For teachers: the medical specialty concerned with the study, diagnosis, and treatment of disorders of the heart and blood vessels.

## Examples

- He decided to specialize in cardiology after medical school.
- Advances in cardiology have significantly improved the survival rates for patients suffering from chronic heart failure.
- The hospital's cardiology department is renowned for its pioneering research into minimally invasive valve replacement procedures and pediatric heart surgery.

## Pitfalls

- Not "He is a cardiology." but "He is a cardiologist." — Learners often confuse the field of study (cardiology) with the person who practices it (cardiologist).

## Usage notes

- Typically functions as an uncountable field of study; specific departments or clinics are referred to as 'the cardiology department'.
