An angina scoring method was designed in the Veterans Administration Coronary Artery Bypass Surgery Study in 1973 to evaluate the effect of medical versus surgical therapy on relief of angina. The score measures the frequency of angina, type of activity producing angina, and use of medications. The score is based on objective responses to specific questions, is easy to compute, and is designed to be administered by a physician familiar with symptoms of angina and coronary artery disease. In this report, the authors evaluate the reproducibiltty, validity, and utility of the angina score in Veterans Administration study patients. Extensions of the scoring method to include newer cardiac drugs and comparison with other methods of grading the severity of angina are also discussed.
