text: According to current understanding, angina pectoris develops when cardiac work, and hence myocardial oxygen need, is greater than the ability of the coronary arterial system to supply oxygen per unit time, Angina can be precipitated by an increase in cardiac work and hence oxygen need, or, conversely, angina may occur after a decrease in the oxygen supply secondary to obstruction of coronary flow or a reduction of arterial oxygen content.
