  3. Background:Transfusion in ACS and PCI • Blood product transfusion is an important complication in acute coronary syndromes (ACS) and percutaneous coronary intervention (PCI) patients treated with potent antithrombotic and antiplatelet agents. • Recent data suggest that transfusion is associated with an increase in adverse outcomes in ACS and PCI, including mortality. • We assessed the impact of transfusion on mortality and ischemic events in patients with ACS from the ACUITY Trial.

Methods: The ACUITY TrialStudy Design and Definitions • The ACUITY Trial compared: heparin or enoxaparin + glycoprotein inhibition (H+GPI), bivalirudin + glycoprotein inhibition (BIV+GPI), and bivalirudin monotherapy (BIV) in 13819 patients with moderate and high-risk NSTE-ACS. • We evaluated outcomes in patients who received transfusion (non-CABG-related) within 30 days of randomization.

  16. Results: The ACUITY Trial (N=13819)Transfusion (non-CABG-related) in ACS • 319 (2.3%) of 13819 patients had transfusion by 30 days. • Patients with transfusion were (p<0.05): • older, female, non-smokers, and had lower body weight, diabetes, hypertension, impaired creatinine clearance, elevated biomarkers, and high-risk (ST-changes or elevated biomarkers). • more likely to receive pre-treatment with a thienopyridine. • more likely to have a >4h randomization to angiography time. • Transfusion was less frequent for: • Bivalirudin vs. Heparin(s) + GPI (1.6% vs. 2.7%, p<0.0001), • Bivalirudin vs. Bivalirudin + GPI (1.6% vs. 2.6%, p<0.0001). • Transfusion was associated with higher 30-day mortality and ischemic event rates.

  23. Conclusion: The ACUITY Trial (N=13819)Transfusion in Patients with ACS • Transfusion is associated with increased 30-day mortality and ischemic event rates in patients with ACS undergoing an invasive strategy. • Bivalirudin results in lower transfusion rates compared to GPI-based strategies. • Factors associated with an increase in the risk of transfusion: • age, female gender, diabetes, hypertension, chronic kidney disease, anemia; • high-risk presentation; • treatment with heparin(s) + GPI. • Knowledge of these factors is important in the assessment of the transfusion risk of, and decision-making for an individual patient. • Minimizing transfusion risk is paramount in order to optimize outcomes in this setting.
