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 review calls for biologically grounded approach to psychiatric diagnosis

A comprehensive invited review published today in Brain Medicine confronts one of the most persistent paradoxes in modern medicine: psychiatry remains the only major clinical discipline that diagnoses complex illness primarily through conversation and symptom checklists, while fields such as oncology and cardiology long ago embraced laboratory markers, imaging, and molecular profiling.

BCAT2 enzyme identified as a target for diabetic foot recovery

Diabetic macrovascular complications are the main cause of death and disability in diabetes patients, of which vascular calcification is one of the key pathological mechanisms. Calcification in atherosclerotic plaque can cause stiffness and decreased compliance of the vascular wall, and induce atherosclerotic plaque rupture, which increases the risk of acute cardiovascular events.
