Surgical treatment of coronary artery disease has been under development for more than 35 years, during which time it has been met with considerable enthusiasm. As the surgical risk decreases, indications for coronary bypass procedures are being liberalized somewhat and increasing numbers of patients are being referred for surgical treatment. The most immediate benefit of such treatment is prompt relief from angina and improvement in the quality of life. Other benefits for various patient subgroups are improvement in left ventricular function and prolonged life. Further experience and controlled studies gradually will elucidate further indications for coronary artery bypass surgery and will result in improved evaluation of this treatment.
