Anticoagulation management during pulmonary endarterectomy with cardiopulmonary bypass and deep hypothermic circulatory arrest.

Introduction: Pulmonary endarterectomy requires cardiopulmonary bypass and deep hypothermic circulatory arrest, which may prolong the activated clotting time. We investigated whether activated clotting time-guided anticoagulation under these circumstances suppresses hemostatic activation.

Methods: Individual heparin sensitivity was determined by the heparin dose-response test, and anticoagulation was monitored by the activated clotting time and heparin concentration.

Myocardial infarction induces atrial inflammation that can be prevented by C1-esterase inhibitor.

Aims: Inflammation plays an important role in the pathogenesis of myocardial infarction (MI). Whether MI induces atrial inflammation is unknown however. Here, we analysed atrial inflammation in patients with MI and in rats with experimentally induced MI.
