Outcome of Coronary Artery Bypass Grafts: Comparison between on Pump and off Pump
,
Abstract
The present study was undertaken to compare the in hospital results of coronary artery bypass graft (CABG) with (on pump) or without (off pump) cardiopulmonary bypass (CPB). Data were collected on all first-time isolated CABGs with saphenous vein and/or artery grafts at Shahid Madani Hospital in Tabriz-Iran, between 2006 and 2009. Age and clinical profile were marched between on pump and off pump group patients. Patients with concomitant cardiac operations or beating pump technique were excluded from the study. The study included 994 patients; CABG with CPB (ONCABG) was done in 578 (58%) and CABG without CPB (OPCABG) in 416 (42%). For pump and off pump group respectively, mortality rate was 2/3%, and 0.2%, the number of grafts was2/92 ± 0.82 and 2/12 ±o.73 and the use of intra aortic balloon-pump (IABP) was1.5% and5.4%. Post operative ejection fraction (EF) was improved in off pump group (47.9±0.6) versus on pump group (44.53±1.5) and the latter group had more post operative atrial fibrillation, Stroke, acute renal failure, bleeding rate and blood products transfusion, prolonged intubation time but was not statistically significance. Meanwhile Hospitalization time and use of inotrops was less in comparison with former patients group. Off pump CABG was a safe method in our series. Patients with comparable risk profiles have similar prevalence's of selected complications after ONCABG and OPCABG, though some clinical and hemodynamic results are better with off pump technique.
