The use of point-of-care testing in detecting platelet function recovery in a patient treated with prasugrel...

A recent administration of potent P2Y₁₂ receptor inhibitor such as prasugrel in patients undergoing cardiac surgery remains a dilemma and little is known about its impact on platelet function recovery. Guidelines recommend discontinuation of prasugrel 7 days before surgery to reduce the risk of surgery-related bleeding. Patients at risk may benefit from preoperative platelet function testing to guide individualized preoperative waiting time. We present a rare case of complete function recovery in a patient treated with prasugrel revealed by preoperative platelet function monitoring before urgent coronary artery bypass surgery (CABG). A complete platelet function recovery was revealed by platelet function testing after discontinuation of prasugrel for four days and patient underwent urgent CABG without increased risk of postoperative bleeding. Our case with a review of literature emphasized that the decision to proceed with urgent CABG in a patient recently treated with prasugrel should be based on a personalized risk assessment and might be supported by preoperative platelet function monitoring to shorten the waiting time.
