Objectivesmany studies have shown that oral beta blockers reduce the incidence of atrial fibrillation after coronary artery bypass. The goal of this study was to determine whether landiolol, an intravenous beta blocker, reduces the incidence of atrial fibrillation after off-pump coronary artery bypass.Methods39 consecutive patients were given landiolol after coronary artery bypass, and 20 who were not given landiolol served as a control group. Landiolol was intravenously administered at 1 µg.kg(-1).min(-1) in the intensive care unit.Resultsthe mean dose of landiolol was 2.3 ± 1.2 1 µg.kg(-1).min(-1). The incidence of atrial fibrillation during intensive care unit stay was significantly lower in the landiolol group compared to the control group: 2.6% (1/39) vs. 20% (4/20). Heart rate after landiolol administration was significantly lower than that before administration, whereas landiolol had no effect on blood pressure. C-reactive protein and creatine kinase levels 7 days after surgery were significantly lower in the landiolol group.Conclusioncontinuous administration of landiolol at a low dose after off-pump coronary artery bypass reduced the incidence of atrial fibrillation.
