OBJECTIVES: Perioperative transfusions are known to increase morbidity and mortality after coronary artery bypass grafting (CABG). The aims of the study were (1) to identify the clinical profile of the patient subset at highest risk from transfusion and (2) to disclose causative relationship and dose-dependency of transfusion on hospital mortality. METHODS: A prospective observational design was employed on a cohort of 1047 consecutive patients (median age 63.2 ± 9.3, 18.8% female, 30.6% diabetics, 31.9% rgent/emergent, 15.3% with low preoperative left ventricular ejection fraction (LVEF)) who underwent on-pump isolated CABG between January 2004 and December 2007. Univariate and multivariate regression analysis and post-hoc risk stratification, by means of propensity scoring and binary segmentation, were adopted.

Abstract

OBJECTIVES: Perioperative transfusions are known to increase morbidity and mortality after coronary artery bypass grafting (CABG). The aims of the study were (1) to identify the clinical profile of the patient subset at highest risk from transfusion and (2) to disclose causative relationship and dose-dependency of transfusion on hospital mortality. METHODS: A prospective observational design was employed on a cohort of 1047 consecutive patients (median age 63.2 ± 9.3, 18.8% female, 30.6% diabetics, 31.9% rgent/emergent, 15.3% with low preoperative left ventricular ejection fraction (LVEF)) who underwent on-pump isolated CABG between January 2004 and December 2007. Univariate and multivariate regression analysis and post-hoc risk stratification, by means of propensity scoring and binary segmentation, were adopted.
