Answer

Angina pectoris is the result of myocardial ischemia caused by an imbalance between myocardial blood supply and oxygen demand. It is a common presenting symptom (typically, chest pain) among patients with coronary artery disease (CAD). Approximately 9.8 million Americans are estimated to experience angina annually, with 500,000 new cases of angina occurring every year.
