The aim of the study is to evaluate if there is an association between platelet inhibition and surgery-related bleeding in patients undergoing emergent cardiac surgery during dual antiplatelet therapy.
||Observational Model: Cohort
Time Perspective: Prospective
||Does Platelet Inhibition Predict Surgery Related Bleeding in Patients Undergoing Emergent Cardiac Surgery During Dual Antiplatelet Therapy - a Pilot Study
Primary Outcome Measures:
- Calculated blood loss [ Time Frame: until postoperative day 5 ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- BARC bleeding [ Time Frame: until postoperative day 2 ] [ Designated as safety issue: No ]
