NO
To investigate the relationship between time-dependent changes in intra-platelet signaling pathways and those in platelet function in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB).
Bio-equivalence
Intraplatelet Bax increases after cardiopulmonary bypass contributes to reduced perioperative platelet-surface GPIb expression and platelet dysfunction during the perioperative period.
Changes in intraplatelet Bax and related pathways are less pronounced during and after off-pump cardiac procedures than for cardiopulmonary bypass.

Male and Female
Patients with or without cardiopulmonary bypass were American Society of Anesthesiologists Physical Status class 3 or 4, and were aged 20-80 years.
We excluded patients and volunteers with conditions known or suspected to independently increase platelet activity; specifically, those with venous thrombosis, sepsis, acute infection, pregnancy, acute coronary syndromes, heparin-induced thrombocytopenic purpura, transient ischemic attacks, severe hypertension (>160/95 mmHg), recent cardiopulmonary bypass, or multiple sclerosis, preoperative hepatic, renal dysfunction, or severe respiratory disease. We also excluded patients who had received platelet transufusion perioperatively, or patients who could not discontinue aspirin 1 week before surgery and other non-steroidal anti-inflammatory medication at least 48 h preoperatively.
