Definition 2
Grading of patient's angina by class (Canadian Cardiovascular Society Grading Scale or CCS classification system): Class I: Ordinary physical activity, such as walking or climbing stairs, does not cause angina. Angina occurs with strenuous, rapid, or prolonged exertion at work or recreation. Class II: Slight limitation of ordinary activity. Angina occurs on walking or climbing stairs rapidly, walking uphill, walking or climbing stairs after meals, or in cold, in wind, or under emotional stress, or only during the few hours after awakening. Angina occurs on walking more than 2 blocks on the level and climbing more than 1 flight of ordinary stairs at a normal pace and in normal condition. Class III: Marked limitations of ordinary physical activity. Angina occurs on walking 1 to 2 blocks on the level and climbing 1 flight of stairs in normal conditions and at a normal pace. Class IV: Inability to perform any physical activity without discomfort- anginal symptoms may be present at rest. (Campeau L. Circulation. 1976;54:522. Letter) (NCI Thesaurus)
