Angina Pectoris
Coronary arterial circulation normally supplies sufficient blood to meet oxygen demands of myocardium. When one or more of these major arteries of coronary arterial circulation becomes severely narrowed by the process of atheroscleresis, the myocardium receives inadequate blood supply.It may not result in any symptom at rest.But during increased work load to the heart(e.g.exercise,emotion etc.) an imbalance arises inbetween the supply &demand for blood.
