Abstract
Cardiovascular disease is the main cause of morbidity and mortality in cardiac patients. Coronary artery bypass grafting (CABG) is the surgical procedure performed by cardiac surgeons worldwide. This study was designed to illustrate a comparison of early clinical outcomes of on pump vs off pump CABG in patients with three vessel disease. Total number of subjects selected were (n=85). In group A, 30 subjects for on pump procedure and in group B, 55 subjects for the off pump procedures were selected. Exclusion criteria of subjects were included: emergency or urgent operations, combined valve surgery, history of renal insufficiency, stroke or transient ischemic attack, patients with atrial fibrillation, atrial flutter, and sustained ventricular tachyarrhythmia. Fourteen parameters were chosen for the evaluation of two procedures. The preoperative risk assessment was counted via parsonnet score system. The number of patients who experienced postoperative atrial fibrillation were 11 (11.94%) in total; 7 cases (23.3%) were related to on pump CABG group and 4 cases (7.3%) were related to off pump CABG group. The frequency of the recurrence of atrial fibrillation, which was 2.9±1.1 days overall; in the on pump CABG group was 3.6±1.2 days while in the off pump CABG group was 2.2±0.9. The ICU stay in on pump group was 2.3±3.7 days, while for off pump group was 1.1±0.4 days. Meanwhile, duration of hospital stay was 18±14 days for the on pump group, whereas that was 15±8.3 days for the off pump CABG group. The conclusion revealed that there is no significant difference in early clinical outcomes of on pump vs off pump CABG in patients with triple vessel disease.
