When revascularization is required for patients presenting with<unk>  angina or NSTEMI, the choice is between PCI and<unk> . In general, the indications for PCI and<unk>  in UA/NSTEMI are similar to those for stable angina. Based on the results of multiple randomized trials,<unk>  is recommended for patients with disease of the left main coronary artery, multivessel disease and impaired left ventricular function. However, recent advances in techniques and less complications with PCI have led to use of PCI for isolated left main disease.
