The association of capillary refill time and return of spontaneous circulation during out-of-hospital cardiac arrest: an observational study.
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

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.

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.
Heart rate (HR) has been proved to be associated with major adverse cardiovascular events (MACE) in Acute coronary syndrome patients. However, the threshold value and clinical significance of time in target of resting heart rate (TTR-HR) remain insufficiently elucidated. Our study aimed to evaluate the independent association between TTR-HR and cardiovascular outcomes in the follow-up study of ACS.

Chronic stress typically leads to deficits in fear extinction. However, when a delay occurs from the end of chronic stress and the start of fear conditioning (a "recovery"), rats show improved context-cue discrimination, compared to recently stressed rats or nonstressed rats. The infralimbic cortex (IL) is important for fear extinction and undergoes neuronal remodeling after chronic stress ends, which could drive improved context-cue discrimination.
