Aprotinin-associated risks in off-pump coronary artery bypass grafting.
BACKGROUND
Little data is available regarding the safety of using the serine protease inhibitor aprotinin in off-pump cardiac surgery. We retrospectively assessed the risks of administering the drug to adult patients undergoing off-pump coronary artery bypass grafting (OPCABG).


METHODS
Aprotinin was administered as a bolus of 1 or 2 million kallikrein inhibiting units to 391 patients following median sternotomy; 370 control patients underwent surgery during the same time period without receiving aprotinin. No other antifibrinolytic agents were administered.


RESULTS
Preoperative characteristics, length of ICU and hospital stay were similar between the mostly medium-risk aprotinin and the control patients. Postoperative cardiac, renal, neurological, and respiratory complications and hospital mortality occurred with comparable frequencies in both groups. Levels of myocardial enzymes during the first 72 h after surgery also did not differ significantly.


CONCLUSIONS
Use of aprotinin in OPCABG was not associated with a higher incidence of hospital mortality, cardiovascular, renal, or other complications. Given the good safety profile in this large patient population we suggest that aprotinin could still be a valid antifibrinolytic treatment option in OPCABG.
