      Inhibition of complement factor 5 (C5) reduced myocardial infarction in animal studies, while no benefit was found in clinical studies. Due to lack of cross-reactivity of clinically used C5 antibodies, different inhibitors were used in animal and clinical studies. Coversin (Ornithodoros moubata complement inhibitor, OmCI) blocks C5 cleavage and binds leukotriene B4 in humans and pigs. We hypothesized ...
    • Open chest and pericardium facilitate transpulmonary passage of venous air emboli

      <p><i>Background:</i> Transpulmonary passage of air emboli can lead to fatal brain- and myocardial infarctions. We studied whether pigs with open chest and pericardium had a greater transpulmonary passage of venous air emboli than pigs with closed thorax. <p><i>Methods:</i> We allocated pigs with verified closed foramen ovale to venous air infusion with either open chest with sternotomy and opening ...
    • Sepsis causes right ventricular myocardial inflammation independent of pulmonary hypertension in a porcine sepsis model

      <i>Introduction</i> - Right ventricular (RV) myocardial dysfunction is a common feature in septic shock. It can worsen outcome, but the etiology is poorly understood. Pulmonary artery hypertension (PAH) plays a part in the pathogenesis of the right heart dysfunction in sepsis but its importance is unknown. In pigs, PAH in sepsis is substantial and the translational value of porcine sepsis models ...
