Low intraoperative oxygen extraction during heart transplant reduces primary graft dysfunction risk in allografts with prolonged ischemic time

Abstract Objective Prolonged ischemic time remains a major barrier to donor use and is strongly associated with primary graft dysfunction in heart transplantation. We evaluated whether intraoperative recipient metabolic adequacy,..

Oxygen Extraction Trajectories During Cardiopulmonary Bypass Impact Postoperative Outcomes in Coronary Artery Bypass Grafting

Abstract Objectives Goal-directed perfusion strategies during cardiopulmonary bypass typically target indexed oxygen delivery thresholds to reduce acute kidney injury and other complications. This delivery-only paradigm may not fully reflect patient-specific..

Elevated oxygen extraction during heart transplantation is associated with increased morbidity and mortality: Implications for goal-directed perfusion

Abstract Background Goal-directed perfusion (GDP) during cardiopulmonary bypass (CPB) commonly targets indexed oxygen delivery (DO2i), yet fixed delivery thresholds may ignore patient-specific metabolic demand. The oxygen extraction ratio (O2ER) integrates..

Atrial fibrillation is associated with higher oxygen extraction in the human heart

Abstract Introduction Atrial fibrillation (AF) is a prevalent cardiac arrhythmia characterized by irregular atrial contractions that compromise ventricular function and cardiac output. In this study we investigated the impact of..
