The SYNTAX score, a comprehensive angiographic scoring system, was recently developed as a tool for risk stratification during the SYNTAX trial (randomized trial comparing coronary artery bypass grafting with percutaneous coronary intervention). We applied the SYNTAX score in patients with multivessel disease and/or left main coronary artery disease who underwent coronary artery bypass grafting to evaluate its role in predicting incidences of major adverse cardiac and cerebrovascular events (MACCE) within 30 days. The study including 100 consecutive patients with multivessel and/or left main CAD who were subjected to CABG. There were divided into three groups according to the Syntax score (<22, 22{u2013}32, and >32). During the 30 days follow- up, cardiovascular events including death, myocardial infarction (MI), and stroke were systematically indexed. The primary end point was the composite criteria death/ MI/stroke. The syntax score ranged from 10-58 with a mean and Standerd deviation 32.03±9.62. Baseline clinical characteristics were similar among the three groups. No statistically significant difference was found for MACCE: 0.0% versus 12.5% versus 20.5% in the groups with a syntax score < 22, 22{u2013}32, and > 32, respectively P value 0.122
