Objective: Recently, Coronary artery bypass grefting (CABG) surgery frequency has increased paralel to the increase of young patients in our country and the world. In this retrospective study, our aim was to evaluate early outcomes of patients ≤40 years old underwent isolated CABG with cardiopulmoner bypass (CPB).

Material and Method: Our study has included 106 patients ≤40 years old who underwent CABG with CPB between April 2004 to January 2012. Demographic data, perioperative and postoperative parameters were evaluated.

Results: Demographic data were examined such as smoking cigarette rate of 59.4%, diabetes mellitus 30.2%, obesity 25.5%, hyperlipidemia 66%. The patients had left main coronary artery, single-vessel, two-vessel and three-vessel disease, 5.7%, 8.5%, 37.7%, 53.8%, respectively. Intraoperative parameters were as follows: mean cross clamp time 37 min, cardiopulmoner bypass time 66.8 min, mean graft number was 2.5. No mortality was seen. Seven cases had atrial fibrillation, and 3 patients had superfical infection at the sapheneous vein harvesting site.

Conclusion: Smoking cigarette and diabetes mellitus are common important risk factors in patients underwent CABG ≤4O years old.
