Why the study?
There is no conclusive evidence that either CABG or PCI is superior to medical therapy alone for treating multivessel coronary artery disease.
Does CABG or PCI improve outcomes compared to medical therapy alone in patients with multivessel CAD, stable angina, and preserved ventricular function?

Does CABG or PCI improve outcomes compared to medical therapy alone in patients with multivessel CAD, stable angina, and preserved ventricular function?
In patients with stable multivessel CAD, medical therapy alone is associated with comparable one-year survival to revascularization, though CABG is significantly more effective for eliminating anginal symptoms.

Schwartz et al. (2004) conducted an RCT in multivessel coronary artery disease (CAD) (n=611). Coronary artery bypass graft surgery (CABG) or percutaneous coronary intervention (PCI) vs. Medical therapy (MT) was evaluated on cardiac mortality, Q-wave myocardial infarction (MI), or refractory angina requiring revascularization.
