Effect of aorta-coronary bypass operation on factors precipitating angina
JJ Barboriak, CV Hughes, AJ Anderson and AA Rimm
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.
