Coronary Artery Disease (CAD): Often referred to as atherosclerosis, affects the vessels that supply blood to heart muscle. It is caused by the deposition of fat, cholesterol, calcium and fibrous tissue, which makes lumen of the arteries narrower.

Angina: It is also called 'angina pectons'.

A symptom of acute chest pain appears when no enough oxygen is reaching the heart muscle.

Heart failure: It means the state of heart when it is not pumping blood effectively enough to meet the needs of the body. It is sometimes called congestive heart failure because congestion of the lungs is one of the main symptoms of this disease
