| Angina or Angina Pectoris
refers to the chest pain resulting from an insufficient blood supply to the heart. |
When coronary arteries get obstructed by atherosclerotic
plaques of fat and lipids, the blood supply they provide to the heart is reduced.
During physical activity or stress, the heart rate
increases as well as the amount of blood needed. If the heart muscle doesn't get the blood
supply it needs, it develops a pain called angina. This pain usually goes away a few
minutes after stopping the activity.
If a coronary artery gets completely clogged, the heart
cells (myocardium) that were getting blood supply from this artery die, which can
lead to heart attack (myocardial infarction) and death.
