PRIMARY outcome

Timeframe: Through the first 48 hours post-operation

Population: The trial was terminated before the outcome measure data were cleaned and adjudicated. All bleeding outcomes data were to be adjudicated by a Clinical Events Committee, which was not convened because the trial was terminated. Therefore, no bleeding outcomes were available.

Incidence of clinically significant perioperative bleeding events, as evaluated by a ranked composite endpoint

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Through 30 minutes post-CPB

Population: Because of the premature discontinuation of the study, this is the only outcome measure collected and analyzed. The change in drug levels was analyzed for both rivaroxaban and apixaban together (not separately), again due to the low number of enrolled subjects.

Percent change in blood apixaban or rivaroxaban levels from pre coronary bypass (CPB), that is, start of device use to 30 min post CPB
