Coronary artery bypass grafting remains a palliative operation for the relief of angina pectoris refractory to drug therapy, and should be performed in those patients unsuitable for coronary angioplasty. A similar approach can be applied to reoperation in patients with recurrent angina bearing in mind the higher operation-related mortality and reduced prospects for satisfactory relief of symptoms in these patients.
冠状动脉旁路移植术仍然是一种用于缓解药物治疗难以控制的心绞痛的姑息性手术，应在那些不适合进行冠状动脉血管成形术的患者中进行。对于复发性心绞痛患者再次手术时，可以采用类似的方法，但要记住这些患者手术相关死亡率较高，且症状得到满意缓解的前景降低。
