Classification based on clinical circumstances
A (secondary angina) - Develops in the presence of extracardiac condition that intensifies myocardial ischemia
B (primary angina) - Develops in the absence of extracardiac condition
C (postinfarction angina) - Develops within 2 weeks after acute myocardial infarction
Classification based on intensity of treatment
(1) - In the absence of treatment for chronic stable angina,
