Objective: The Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile international normalized ratio, Elderly, Drugs/alcohol (HAS-BLED) score has been developed to predict the risk of potential bleeding in anticoagulated patients affected by atrial fibrillation. The aim of this study was to test the hypothesis that the HAS-BLED score is associated with major bleeding also in patients after cardiac surgery., Design: Prospective, single-center nonrandomized study., Setting: Single hospital center., Participants: Patients., Interventions: Standard cardiac operation and analysis of major bleeding events. A total of 1,173 consecutive adult patients who underwent cardiac surgery were recruited. Major bleeding was defined according to the Bleeding Academy Research Consortium classification (3, 4, 5). Bleeding events were classified as early bleeding (within 48 hours after the operation) and late bleeding (after 48 hours and within 90 days, postoperatively). Patients were followed after the discharge for 120 days, through outpatient clinic visits and by phone calls., Measurement and Main Results: A total of 29 (2.5%) patients experienced early bleeding events (2.5%), while 34 (2.9%) experienced late bleeding events. Univariate and multivariable analysis did not find that the HAS-BLED score was associated with early bleeding, but it was associated significantly with late bleeding (odds ratio [OR], 1.86; 95% confidence intervals [CI] 1.32-2.62, and OR 1.67; 95% CI 1.19-2.35, respectively)., Conclusion: The HAS-BLED score is associated with increased risk of major bleeding events after cardiac surgery procedures. This may help to plan the standard anticoagulation/antiplatelet therapy in cardiac surgical patients with a higher HAS-BLED score., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Purpose: To investigate the impact of minor perioperative bleeding requiring transfusion of 1-2 red blood cell (RBC) units on the outcome after coronary artery bypass grafting (CABG)., Methods: Sixteen cardiac surgical centers contributed to the prospective European CABG registry (E-CABG). 1014 patients receiving 1-2 RBC units during or after isolated CABG were compared to 2264 patients not receiving RBCs., Results: In 827 propensity score matched pairs, transfusion of 1-2 RBC units did not affect the risk of in-hospital/30-day death (p=0.523) or stroke (p=0.804). However, RBC transfusion was associated with an increased risk of acute kidney injury (p=0.008), sternal wound infection (p=0.001), postoperative use of antibiotics (p=0.001), prolonged use of inotropes (p<0.0001), use of intra-aortic balloon pump (p=0.012), length of intensive care unit stay (p<0.0001) and length of in-hospital stay (p<0.0001). Matched paired analysis excluding pre- and postoperative critical hemodynamic conditions showed that RBC transfusion was associated with an increased risk of major complications except in-hospital/30-day death., Conclusion: Minor perioperative bleeding and subsequent transfusion of 1-2 RBC units did not affect the risk of early death, but increased the risk of other major adverse events. Minimizing perioperative bleeding and prevention of even low-volume RBC transfusion may improve the outcome after CABG., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Objective: The authors aimed to validate the European Multicenter Study on Coronary Artery Bypass Grafting (E-CABG) classification of postoperative complications in patients undergoing coronary artery bypass grafting (CABG)., Design: Retrospective, observational study., Setting: University hospital., Participants: A total of 2,764 patients with severe coronary artery disease. Complete baseline, operative, and postoperative data were available for patients who underwent isolated CABG., Interventions: Isolated CABG., Measurements and Main Results: The E-CABG complication classification was used to stratify the severity and prognostic impact of adverse postoperative events. Primary outcome endpoints were 30-day, 90-day, and long-term all-cause mortality. The secondary outcome endpoints was the length of intensive care unit stay. Both the E-CABG complication grades and additive score were predictive of 30-day (area under the receiver operating characteristics curve 0.866, 95% confidence interval [CI] 0.829-0.903; and 0.876; 95% CI 0.844-0.908, respectively) and 90-day (area under the receiver operating characteristics curve 0.850, 95% CI 0.812-0.887; and 0.863, 95% CI 0.829-0.897, respectively) all-cause mortality. The complication grades were independent predictors of increased mortality at actuarial (log-rank: p<0.0001) and adjusted analysis (p<0.0001; grade 1: hazard ratio [HR] 1.757, 95% CI 1.111-2.778; grade 2: HR 2.704, 95% CI 1.664-4.394; grade 3: HR 5.081, 95% CI 3.148-8.201). When patients who died within 30 days were excluded from the analysis, this grading method still was associated with late mortality (p<0.0001). The grading method (p<0.0001) and the additive score (rho, 0.514; p<0.0001) were predictive of the length of intensive care unit stay., Conclusions: The E-CABG postoperative complication classification seems to be a promising tool for stratifying the severity and prognostic impact of postoperative complications in patients undergoing cardiac surgery., (Copyright © 2016 Elsevier Inc.
