BACKGROUND: It has not been established whether off-pump coronary artery bypass grafting (OPCABG) is less invasive than conventional CABG. In our experience, OPCABG has several advantages such as shorter operative duration, decreased requirement of blood transfusion and myocardial protection compared with conventional CABG. However, frequency of postoperative paroxysmal atrial fibrillation (PAF) is similar between these techniques and early postoperative C-reactive protein (CRP) levels have been shown to be significantly higher in OPCABG. We hypothesized that preoperative steroid administration, routinely used only in conventional CABG, may alleviate high postoperative PAF and CRP levels. Therefore, a prospective, double-blind, clinical trial was conducted in OPCABG patients to investigate the clinical effects of preoperative steroid administration. METHODS: Thirty OPCABG patients were randomly divided into 2 groups: control (Group C: n = 15) and methylprednisolone (Group M: n = 15) groups. Group M patients were intravenously administered 1000 mg methylprednisolone during anesthesia induction. RESULTS: Hospital death and infectious complication such as mediastinitis were not observed in either group. Postoperative PAF occurred in 47 % (7/15) of patients in group C but in only 1 patient in group M (7 %, P = 0.013). Early postoperative CRP levels were significantly lower in group M than in group C (peak values on postoperative day 2: group M 15 ± 6 mg/dL vs. group C 23 ± 4 mg/dL; P = 0.0002). CONCLUSIONS: Preoperative steroid administration in OPCABG patients significantly suppresses CRP elevation and prevents postoperative PAF without increasing in-hospital mortality or infectious complications.
