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.

New 2025 guidelines focus on early intervention and lifestyle to manage high blood pressure

Preventing and managing high blood pressure with healthy lifestyle behaviors, such as following a heart-healthy diet including reducing salt intake, staying physically active, maintaining a healthy weight and managing stress—combined with early treatment with medication to lower blood pressure if necessary—are recommended to reduce the risk of heart attack, stroke, heart failure, kidney disease, cognitive decline and dementia, according to a new clinical guideline published today in the American Heart Association's peer-reviewed journals Circulation and Hypertension, and in JACC, the flagship journal of the American College of Cardiology.

TEER shows promising outcomes in elderly patients with atrial functional mitral regurgitation

The mitral valve controls blood flow between the heart's left atrium and ventricle. When structural changes affect the atrium or valve, it may not close fully-causing blood to leak backwards, a condition known as atrial functional mitral regurgitation (AFMR).
