Angina or chest pain: It is the most common indication of heart disease caused due to decreased blood flow to heart muscles. The heart is dependent on oxygen for its functioning and pumping of blood, yet sometimes, due to various genetic and environmental reasons, the blood vessels supplying blood to the heart narrow unexpectedly, causing decreased blood flow to the heart. This abrupt decrease in blood flow leads to increased stress on the heart to pump blood towards different organs causing an event of acute chest pain that starts from the arm along the jaw and finally involves the chest. Angina pectoris is of 3 types:

1) Stable Angina: is the most common type in which blood flow to the heart is low as compared to what it needs to function, caused by increased physical activity.

2) Unstable angina: is the most lethal type in which blood supply to the heart decreases abruptly due to blockage of the artery by a clot, etc.

3) Variant angina: occurs at rest due to spasmodic narrowing of the artery.
