What is cardiology?

Cardiology is a medical specialty and a branch of internal medicine concerned with disorders of the heart. It deals with the diagnosis and treatment of such conditions as congenital heart defects, coronary artery disease, electrophysiology, heart failure and valvular heart disease. Subspecialties of the cardiology field include cardiac electrophysiology, echocardiography, interventional cardiology and nuclear.

Specialized Qualification

All cardiologists study the disorders of the heart, but the study of adult and child heart disorders are through different training pathways. Therefore, an adult cardiologist (often simply called “cardiologist”) is inadequately trained to take care of children, and pediatric cardiologists are not trained to take care of adult heart disease. The surgical aspects are not included in cardiology and are in the domain of cardiothoracic surgery. For example, coronary artery bypass surgery (CABG), cardiopulmonary bypass and valve replacement are surgical procedures performed by surgeons, not cardiologists. However the insertion of stents and pacemakers is performed by cardiologists.

Nature of the work

Cardiologists work with adult patients—pediatric cardiology is a separate specialty.

Cardiologists manage patients with conditions such as:

angina (chest pain caused by narrowing of the coronary arteries)
arrhythmias, eg atrial fibrillation (irregular heartbeat)
heart murmurs due to heart valve disease
cardiomyopathy (disease of the heart muscle) with heart failure including pulmonary
oedema (accumulation of fluid)
coronary artery thrombosis or myocardial infarction (heart attack) often associated with high blood pressure (hypertension) and high cholesterol
diseases of the arteries (atherosclerosis, arteritis, atheroma)
hole in the heart and other forms of congenital heart disease within adult
lifeincluding transition from paediatric care and shared care of pregnant women with heart disease
