Heart

Angina
Angina is the chest discomfort or pain that occurs when the oxygen supply to an area of the heart muscle does not meet the demand.

Abdominal aortic aneurysm
The aorta is the largest blood vessel and carries oxygenated blood away from the heart. An abdominal aortic aneurysm is the localised dilation of the aorta in the abdomen.

Blood clots
Blood clotting is a natural process that allows the blood to thicken and form a clot of blood cells and fibrin to stop the bleeding when a blood vessel is severed.

Chest pain
Chest pain can be due to a heart attack or angina or could be caused by other factors. It can be an important warning symptom of a heart attack.

Heart failure
Heart failure means that your heart is unable to pump enough blood to your body’s tissues and organs to meet their needs.

Heart block
Heart block (AV block) is a delay or an interruption in the transmission of an impulse from the atria to the ventricles.

Sudden cardiac death
Sudden cardiac death (also called sudden arrest) is an umbrella term for many different causes of cardiac arrest in young people.

Pulmonary hypertension
Pulmonary hypertension is a serious condition that causes the blood pressure in the arteries to your lungs to become abnormally high which can result in heart failure.

Arrhythmia
An arrhythmia is any deviation from the normal rhythm of the heart. Arrhythmias are important as they cause unpleasant symptoms, which may progress to serious complications.

Barlow's syndrome
Barlow's syndrome is a relatively common condition in which there is an abnormality of the mitral valve of the heart.

Cardiomyopathy
The cardiomyopathies are a group of heart diseases that are defined by myocardial (heart muscle) dysfunction as the initial event.

Heart attack
A heart attack is the death of heart muscle due to the complete blockage of a diseased coronary artery due to a blood clot.

Heart-valve disease
Heart-valve disease refers to any condition affecting the function of any or all of the four valves of the heart.

Pulmonary thromboembolism
Pulmonary embolism, lung blood clot, PE. Pulmonary thromboembolism is the sudden occlusion of a lung artery due to a blood clot that dislodged somewhere else in the body.

Ventricular tachycardia
A tachycardia is an increase in heart rate above the normal rate. Ventricular tachycardia refers to a tachycardia which arises in the ventricles of the heart.
