title: Effect of aorta-coronary bypass operation on factors precipitating angina.
abstract: About two thirds (65 percent) of 271 male patients and one half of the 44 female patients who had angina pectoris prior to the aorta-coronary bypass operation experienced total relief of symptoms 1 year after the operation. This was especially apparent for angina associated with walking activity and the postprandial angina. In the nonoperated patients who had angina pectoris and only mild or no coronary artery obstruction, 38 percent of the 127 men and 27 percent of the 73 women were free of symptoms 1 year after the original examination.
