Criteria for Chronic Stable Refractory Angina
The criteria for chronic stable refractory angina were defined by Mannheimer and colleagues in 2002 as a chronic condition characterized by the presence of angina caused by coronary insufficiency in the presence of coronary artery disease which cannot be controlled by a combination of medical therapy, angioplasty and coronary bypass surgery. The presence of reversible myocardial ischemia should be clinically established to be the cause of the symptoms. Chronic is defined as a duration of more than 3 months.
