Condition: Blood Platelet Disorders · Cardiac Surgery · Postoperative Bleeding · Sponsor: Fundación Instituto de Estudios de Ciencias de la Salud de Castilla y León
Perioperative bleeding requiring blood transfusion is common during cardiovascular surgery, especially in procedures requiring cardiopulmonary bypass. Adenosine diphosphate (ADP) plays a fundamental role in platelet function. Several studies have shown that some patients not receiving antiplatelet therapy undergoing cardiovascular surgery have decreased platelet ADP receptor activity; the prevalence of this condition can be as high as 36%. Furthermore, extracorporeal circulation itself has been shown to cause a reduction in platelet function. Platelet dysfunction due to reduced platelet receptor activity after cardiac surgery is potentially a common cause of bleeding, perioperative blood transfusion, and surgical reexploration in patients not receiving antiplatelet agents. However, these studies are conducted with few patients and present some contradictory results, so the evidence is still scarce. The study hypothesis is that preoperative platelet dysfunction for ADP measured by TEG® Platelet Mapping™ is associated with a higher incidence of moderate-severe bleeding after CPB in patients undergoing cardiovascular surgery.
