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.
冠状动脉疾病的外科治疗已经发展了35年多，在此期间受到了相当大的关注。随着手术风险的降低，冠状动脉搭桥手术的适应症有所放宽，越来越多的患者被转诊接受手术治疗。这种治疗最直接的好处是迅速缓解心绞痛并改善生活质量。对不同患者亚组的其他好处是改善左心室功能和延长寿命。进一步的经验和对照研究将逐渐阐明冠状动脉搭桥手术的更多适应症，并将改进对这种治疗的评估。
