Background: Percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) stands as effective treatment choices for coronary revascularization among selected cases developing stable coronary artery disease as well as ischemia. This work was aimed at comparing the MACE outcomes (total deaths, myocardial infarction (MI), coronary revascularization, stroke, as well as hospitalization) between cases developing intermediate syntax score who underwent distal left main coronary artery stenting and others who underwent coronary artery bypass graft with a six-month follow-up period. 
Methods: The cohort study included 100 cases, with an age range falling between eighteen and seventy-fixe years, both genders, developing de novo lesions, stenosis equal to or above 50% of left main coronary artery, having stable/unstable angina or atypical chest pain and, in asymptomatic cases, they had positive evidence of myocardial ischemia. Participants underwent an equal categorization into two groups: group A: Left main coronary artery stenting and group B: CABG.
Results: Syntax score was significantly reduced within PCI group as opposed to CABG group (p=0.001). Stents number exhibited significantly greater measurements within CABG group as opposed to PCI group (p=0.001). HbA1c exhibited significantly greater values within PCI group as opposed to CABG group (p=0.017). Coronary angiography findings exhibited significant variances among PCI and CABG groups (p<0.001). Outcome as well as complications at discharge and after 6 months were insignificantly different between the two groups. Cardiac events at discharge and within a six-month period exhibited insignificant variance among both groups.
Conclusions: Syntax score exhibited a significant reduction within PCI group in comparison to CABG group. In cases developing intermediate SYNTAX II score, no significant variance was documented among the PCI and CABG with respect to outcome and complications at discharge or after 6 months which including MACE, MI, stroke, heart failure, revascularization and death.
