what is angina pectoris? Angina pectoris is a common symptom of coronary artery disease (CAD) caused by transient episodes of myocardial ischemia and anoxia. Pathophysiology of angina Angina pectoris results from an imbalance between oxygen supply-demand relationship in ischemic regions of the myocardium
