Short-term outcomes of left main coronary artery disease treatment: A comparative study of optimal medical therapy, coronary artery bypass grafting, and percutaneous coronary intervention

Background: Several studies have compared treatment strategies in patients with left main coronary artery (LMCA) disease. However, short-term outcomes have scarcely been reported. Materials and Methods: In this prospective, single-center, descriptive study, conducted between January 1, 2017, and January 1, 2018, patients with LMCA disease were treated through medical follow-up (MFU), percutaneous coronary intervention (PCI), or coronary artery bypass grafting (CABG). Results: A total of 149 patients participated in the study. Of the 149 patients, 27 (18.1%), 69 (46.3%), and 53 (35.6%) patients were treated with CABG, MFU, and PCI, respectively. The SYNTAX score was 31.0 ± 5.8, 29.9 ± 7.0, and 21.0 ± 6.8 in the CABG, MFU, and PCI groups (P
