ObjectiveThe 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.DesignProspective, single-center nonrandomized study.SettingSingle hospital center.ParticipantsPatients.InterventionsStandard 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 ResultsA 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).ConclusionThe 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.
