Cardiology is a medical specialty dealing with disorders of the heart.  The field includes diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.  Cardiologists investigate patients with suspected heart disease by taking a very careful, extensive history of the patient's condition, and performing a complete physical examination.  Physicians specializing in this field of medicine are called cardiologists.

Cardiologists should not be confused with cardiac surgeons, cardiothoracic and cardiovascular, who are surgeons who perform surgery on the heart and the associated great vessels.

Diseases of the cardiovascular system

Disorders of the coronary circulation
Contrary to a basic understanding of the cardiovascular system, the heart cannot receive enough oxygen and nutrients from the blood it pumps and it must be supply itself with blood as if it were any other organ in the body.  This circulation of blood is called the coronary circulation.  The coronary circulation consists of coronary arteries and coronary veins.

Disorders of the coronary circulation can have devastating effects to the heart since damage to the heart can reduce coronary circulation which causes further damage.

Cardiac arrest
Cardiac arrest refers to the cessation of normal systemic circulation due to failure in proper contraction of the heart.  There are several conditions that can cause cardiac arrest.

Disorders of the myocardium (muscle of the heart)
•    Cardiomyopathy
•    Congestive heart failure
•    Ventricular hypertrophy
•    Primary tumours of the heart
•    Myocardial rupture

Disorders of the pericardium (outer lining of the heart)
•    Pericarditis
•    Pericardial tamponade
•    Constrictive pericarditis

Disorders of the heart valves
•    Aortic valve disorders
•    Mitral valve disorders
•    Pulmonary valve disorders
•    Tricuspid valve disorders
•    Wolff-Parkinson-White syndrome (WPW syndrome)

Congenital heart disease
•    Atrial septal defect
•    Ventricular septal defect
•    Patent ductus arteriosus
•    Bicuspid aortic valve

Tetralogy of Fallot
•    Transposition of the great vessels (TGV)
•    Hypoplastic left heart syndrome
•    Truncus Arteriosus
Diseases of blood vessels (Vascular diseases)
•    Vasculitis
•    Atherosclerosis
•    Aneurysm
•    Varicose veins
•    Economy class syndrome
•    Diseases of the aorta
•    Diseases of the carotid arteries
