What is Angina Angina is a type of chest pain or discomfort that occurs whenever your heart is not receiving all the oxygen that it needs to do its job.

The heartbeat is controlled by electrical impulses that normally travel on a smooth path through the heart, causing the ventricles and atria to contract in a specific order, pushing blood through the lungs and body. These electrical impulses are controlled by the heart's sinoatrial (SA) node, or...
Atrial fibrillation is a type of irregular heartbeat, or arrhythmia, that happens when the electrical signalling in your heart is disrupted. Different types of atrial fibrillation may last for seconds or be permanent. The condition is more common in older people and can have many different causes...
Amyloidosis is a rare, chronic condition in which abnormal proteins bunch together to form amyloid deposits. These deposits can build in certain body organs such as the heart, nerves, gastrointestinal tract, and kidneys, and may cause damage. What is cardiac amyloidosis? Cardiac amyloidosis is a...
Cardiac arrest is a sudden loss of heart function, breathing and consciousness, usually caused by disruptions to the normal electrical activity within the heart.

Neuromuscular disorders represent a heterogeneous group of genetic abnormalities affecting the normal function of nerve and muscle. The age of onset is variable and clinical presentations depend on the type of condition. Symptoms can include muscle pain, weakness, and spasms. Some conditions can...
What Is Cardiac Sarcoidosis? Cardiac sarcoidosis is a rare disease in which clusters of white blood cells, called granulomas, form in the tissue of the heart. Any part of the heart can be affected, though these cell clusters most often form in the heart muscle where they can interfere with the heart...

A coronary abnormality may involve an irregularity with its starting point, course, shape, or branching. Coronary artery anomalies affect less than 1% of the population and are congenital (meaning they are present at birth). They may not be diagnosed until adolescence or adulthood because of a lack...
Coronary artery disease (CAD) is a condition which affects the arteries that supply the heart with blood. It is usually caused by atherosclerosis which is a buildup of plaque inside the artery walls. This buildup causes the inside of the arteries to become narrower and slows down the flow of blood...
Normally, when blood glucose levels rise after a meal, the pancreas (an organ near the stomach) releases a hormone called insulin to stimulate your cells and liver to absorb the glucose. With diabetes, the body either does not produce enough insulin (type 1 diabetes) or cannot use the hormone...
