Lung injury in myocardial infarction-associated cardiogenic shock supported by venoarterial extracorporeal membrane oxygenation: a scoping review.

Background: Acute lung injury and acute respiratory failure are frequent complications of cardiogenic shock and are associated with increased morbidity and mortality. Even with increased use of temporary mechanical circulatory support, such as venoarterial extracorporeal membrane oxygenation (VA-ECMO), acute lung injury related to cardiogenic shock continues to have a determinantal effect on patient outcomes.
Objectives: To summarize potential mechanisms of acute lung injury described in patients with cardiogenic shock supported by VA-ECMO and determine current knowledge gaps.
Basal ganglia components have distinct computational roles in decision-making dynamics under conflict and uncertainty.

The basal ganglia (BG) play a key role in decision-making, preventing impulsive actions in some contexts while facilitating fast adaptations in others. The specific contributions of different BG structures to this nuanced behavior remain unclear, particularly under varying situations of noisy and conflicting information that necessitate ongoing adjustments in the balance between speed and accuracy. Theoretical accounts suggest that dynamic regulation of the amount of evidence required to commit to a decision (a dynamic "decision boundary") may be necessary to meet these competing demands.

Crit Care
January 2025
Emergency Medical Service Vienna, Vienna, Austria.
Introduction: Microcirculatory alterations are predictive of poor outcomes in patients with shock and after cardiac arrest in animal models. However, microcirculatory alterations during human cardiac arrest have not yet been studied.
Methods: We prospectively included adult patients receiving resuscitation after witnessed out-of-hospital cardiac arrest.
Survivorship After Cardiogenic Shock.
Circulation
January 2025
Division of Cardiology, Department of Internal Medicine (E.J.H., M.A.F.), University of Texas Southwestern Medical Center, Dallas.
Advances in critical care therapies for patients with cardiogenic shock (CS), including temporary mechanical circulatory support and multidisciplinary shock teams, have led to improved survival to hospital discharge, ranging from 60% to 70%. After their index hospitalization, however, survivors of CS may continue to face cardiac as well as extracardiac sequelae of these therapies and complications for years to come. Most studies in CS have focused primarily on survival, with limited data on long-term recovery measures among survivors.

Division of Cardiovascular Medicine (E.Y., L.E., J.M.H., S.B.), New York University.
Background: The aim of this study was to examine the impact of early versus delayed catheter-based therapies (CBTs) on clinical outcomes in patients with acute intermediate-risk pulmonary embolism (PE).
Methods: This retrospective cohort study analyzed data from 2 academic centers involving patients with intermediate-risk PE from January 2020 to January 2024. Patients were divided into early (<12 hours) and delayed CBT (≥12 hours) groups.
