Critical warm ischemia time point for cardiac donation after circulatory death.

Donation after circulatory death (DCD) represents a promising opportunity to overcome the relative shortage of donors for heart transplantation. However, the necessary period of warm ischemia is a concern. This study aims to determine the critical warm ischemia time based on in vivo biochemical changes.

Association between post-procedural hyperoxia and poor functional outcome after mechanical thrombectomy for ischemic stroke: an observational study.

Background: The actual effects of oxygen therapy on patients who have suffered a stroke are still unknown, and its recommendation as a routine measure in emergency services remains controversial. The aim of this study is to determine the effect of hyperoxia in functional recovery in patients with ischemic stroke who underwent intra-arterial mechanical thrombectomy (IAMT).

Methods: A prospective observational cohort study that included all adult patients consecutively admitted to the intensive care unit (ICU) due to an ischemic stroke in the anterior cerebral circulation and following an IAMT intervention, between 2010 and 2015.

Assessment of Preoperative Anxiety in Cardiac Surgery Patients Lacking a History of Anxiety: Contributing Factors and Postoperative Morbidity.

Objectives: The aim of this study was to measure the level of preoperative anxiety in patients scheduled for cardiac surgery, identify any influencing clinical factors, and assess the relationship between anxiety and postoperative morbidity.

Design: A prospective and consecutive study.

Setting: A single university hospital.

Galectin-3 as a marker of interstitial atrial remodelling involved in atrial fibrillation.

Remodelling in the atria could appear as a result of hypertension, diabetes or ischaemic heart disease. Galectin-3 (Gal-3) is a mediator of profibrotic pathways and a potential biomarker of cardiac remodelling. We prospectively recruited consecutive patients undergoing elective cardiac surgery.

Von Willebrand factor is associated with atrial fibrillation development in ischaemic patients after cardiac surgery.

Aims: Atrial fibrillation (AF) is associated with an increased morbidity and mortality after cardiac surgery. Von Willebrand factor (vWF) has been proposed as a biomarker of endothelial damage/dysfunction. We hypothesized that vWF levels could be used as valuable biomarker for AF occurrence after cardiac surgery.

[HDL cholesterol and high-sensitive troponin T as predictive biomarkers of atrial fibrillation after heart surgery].

Introduction: Atrial fibrillation (AF) has an incidence rate of approximately 30% and is the most frequent arrhythmia following heart surgery. Factors such as inflammation, the presence of heart fibrosis, stress and cardiomyocyte apoptosis, have all been associated with AF.

Objectives: We believe that atrial remodelling is a pre-existent process in patients with post-surgical AF.

Acute aortic syndrome mimicking intramural hematoma with hemopericardium.

We report a case of acute aortic syndrome in a 64-year-old man who presented with chest pain and hypotension. His electrocardiogram and cardiac troponins were normal. Computed tomography showed hemopericardium of 2.

[Preliminary experience in an intensive care unit with Impella Recover. A new circulatory support system in patients with low cardiac output].

The low cardiac output syndrome following cardiopulmonary bypass is characterized by poor left ventricular contractibility that requires the support of high doses of vasoactive drugs, intra-aortic balloon pump, and sometimes makes it impossible to disconnect the extracorporeal circulation. We report 5 cases in which a "recently created" device in left ventricular support was inserted, the Impella Recover (Impella CardioSystems AG, Aachen, Germany) due to cardiogenic shock at the end of the surgery. Four of these patients recovered their heart function and the ventricular support could be removed after 70+/-55 h.
