ABSTRACT
Coronary artery bypass grafting (CABG) in patients with systolic heart failure (HF) carries high morbidity and mortality rates. Reducing perioperative mortality with beta-blockers (BBs) may help improve outcomes. Analysis of 4903 patients who underwent isolated CABG surgery was performed. In-hospital mortality of systolic HF patients who received BBs was 2.03%; systolic HF patients who did not receive BBs had a mortality of 5.20%. Thirty-day mortality was 2.98% in the patients with systolic HF who received BBs and 6.16% in the patients who did not. beta-Blockade did not affect the mortality in patients with preserved systolic function. Cardiogenic shock was a predictor of increased mortality in patients with systolic HF, while BBs reduced mortality. BBs are associated with decreased in-hospital and 30-day mortality in patients with systolic HF. BB therapy should be considered in patients with systolic HF who are undergoing CABG.
