Developmental phase



Assessment

Primary outcomes

Intraplatelet Bax increases after cardiopulmonary bypass contributes to reduced perioperative platelet-surface GPIb expression and platelet dysfunction during the perioperative period.

Key secondary outcomes

Changes in intraplatelet Bax and related pathways are less pronounced during and after off-pump cardiac procedures than for cardiopulmonary bypass.

Key inclusion criteria

Patients with or without cardiopulmonary bypass were American Society of Anesthesiologists Physical Status class 3 or 4, and were aged 20-80 years.

Key exclusion criteria

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.
