Canadian Cardiovascular Society classification

TABLE 4-3. The Canadian Cardiovascular Society Classification System of Angina49... 

Angina that increases in severity (i.e., by Canadian Cardiovascular Society Classification System Class of one level or greater), frequency, or duration, or that occurs with less provocation over a short time period (i.e., within 2 months). 

TABLE 15—2. Grading of Angina Pectoris by the Canadian Cardiovascular Society Classification System... 

Angina may be classified according to symptom severity, disability induced, or a specific activity scale (Tables 15-1 and 15-2). The specific activity scale developed by Goldman and coworkers may be preferable because it has been shown to be equal to or better than the New York Heart Association (NYHA) or Canadian Cardiovascular Society (CCS) functional classifications for reproducibility and provides better agreement with treadmill testing.
