Acute chest pain appears when no enough oxygen is reaching the heart muscles. The term angina pectoris means chest pain. It is more common in middle aged and elderly people and is seen in both men and women. It occurs due to conditions that affect the blood flow.
It should be differentiated from other conditions such as:
Heart failure where the heart does not pump blood effectively enough to meet the needs of the body.
Heart attack occurs when heart muscles are suddenly damaged by inadequate supply of blood.
Cardiac arrest is the condition where the heart stops beating i.e complete stoppage of heart beat.
