What are the benefits of CABG compared with medical therapy for patients with left main or 3-vessel CAD?
The studies established that CABG is more effective than medical therapy at relieving anginal symptoms and offers a survival advantage over medical therapy for patients with left main or 3-vessel CAD. In MASS II (Medicine, Angioplasty, or Surgery Study II), patients with multivessel CAD who were treated with CABG were less likely than those treated with medical therapy to have a subsequent MI, need additional revascularization, or experience cardiac death in the 10 years after randomization.
