Intensive Care Unit Management After Cardiac ARrest in Russia
Post Cardiac Arrest SyndromeThe purpose of this study is to study the prevalence of post cardiac arrest syndrome (PCAS) among ICU patients, to analyze the effectiveness of intensive care, to assess the factors associated with death and the development of severe neurological deficits.

Prehospital TEE in Cardiac Arrest
EchocardiographyTransesophageal1 moreThis study shall investigate the feasibility of prehospital performed trans-esophageal echocardiography in out of hospital cardiac arrest. The investigators will include ten patients undergoing advanced life support in this study and determine if it is possible to acquire adequate trans-esophageal images within 10 minutes after arrival of the study team on scene.

NFL Dynamics as a Predictor Factor in Patients With Out of Hospital Cardiac Arrest
Out-Of-Hospital Cardiac ArrestNeurological InjuryTo investigate the pharmacodynamics of light chain of NFL in patients with out-of hospital cardiac arrest after successful resuscitation and determine the difference in the serum levels of NFL in patients with favorable neurological outcome compared to those with non-favorable neurological outcome.

Removing Surrogates' Uncertainty to Reduce Fear and Anxiety After Cardiac Events
Cardiac ArrestThe goal of this study is to test the feasibility and acceptability of an informational website to reduce uncertainty, psychological distress, and caregiver burden among close family members of cardiac arrest patients. The investigators hypothesize that participants who receive access to the website will have lower rates of uncertainty, psychological distress, and caregiver burden at 3 months post-hospital discharge compared to participants who receive usual care.

Early Cessation of Sedation and TTM in Patients With a Favourable EEG After Cardiac Arrest
Hypoxia-IschemiaBrain1 moreThe objective of this study is to estimate the feasibility and safety of early weaning from ICU treatment in patients after cardiac arrest and an early (< 12 h) favourable EEG pattern (indicating no or mild postanoxic encephalopathy).

Korean Cardiac Arrest Research Consortium
Out-of-Hospital Cardiac ArrestThis study will evaluated the epidemiology and the outcomes of patients suffering out-of-hospital cardiac arrest with presumed cardiac etiology in Korea.

Post-Coronavirus Disease of 2019 (COVID-19) Rehabilitation Clinics in Saudi Arabia
FatigueCardiopulmonary Arrest5 moreThis intervention study aims to evaluate the before and after changes in physical fitness, cardiorespiratory status, exercise capacity, fatigue, anxiety, dyspnea, psychoemotional conditions, and quality of life through 3 sessions per week for 4-week of an intensive therapeutic program in post coronavirus survivors. In addition, it aims to answer the main questions before and after the clinical trial study. Does three sessions per week for 4-week of an intensive therapeutic program improve patients' physical fitness, cardiorespiratory status, and exercise capacity? Does it improve physical endurance and fitness, enhancing fatigue, anxiety, and dyspnea on post coronavirus patients? Participants will ask first to answer these questionnaires before and after the intervention. Berg Balance Scale (BBS): to assess the patient's ability (or inability) to safely balance (standing, active, and fall risk) during a series of planned tasks. The Modified Medical Research Council (mMRC) Dyspnea Scale: is used to assess patients' degree of baseline functional impairment due to dyspnea from respiratory diseases. Depression, Anxiety, and Stress Scale- 21 Items (DASS-21): measures the emotional states of depression, anxiety, and stress. Fatigue Assessment Scale (FAS): evaluates symptoms of chronic fatigue. Quality of Life (QOL)-short form-36: to assess the quality of life and calculate eight subscales: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health. After answering the questionnaires, the patients will then go through multiple tests before and after the intervention: A 6-min walk test (6-MWT): is the primary measure of this study to assess aerobic capacity and endurance. 10-meter walk test (10MWT): assess walking speed in meters per second over a short distance and assess capacity and endurance. Time Up and Go (TUG) test: assess lower extremity function, mobility, and fall risk. The TUG test is the shortest, most straightforward clinical balance test available to predict the risk of falls. 1-min sit-to-stand test (1-MSTST): assess lower extremity strength for one minute.

Better Mechanistic Understanding of and Risk Stratification for Ventricular Tachyarrhythmias Through...
Ventricular TachycardiaVentricular Arrythmia10 moreThis study aims to evaluate the electrophysiological properties of the heart conduction system in patients with (increased risk of) ventricular tachyarrhythmias (VTA) and sudden cardiac arrest, and in a control cohort. The electrophysiological properties will be measured with the relatively new technique ECG-Imaging (ECGI). Moreover, clinical data of subjects will be gathered. By combining the data from the data gathering and the results of ECGI, the investigators hope to increase mechanistic understanding of and risk stratification for VTAs. The investigators aim to be able to identify patients at risk of an arrhythmic event, and aim for better treatment strategies in the future.

The Effect of Lumbar CSF Drainage on the Neurologic Outcome Improvement in OHCA Underwent TTM
Heart ArrestOut-Of-Hospital1 moreAim: The investigators aim to evaluate the effect of lumbar cerebrospinal fluid (CSF) drainage on neurologic outcome in post-cardiac arrest (CA) patients treated with target temperature management (TTM). Methods: This is a prospective single-center study conducted from May 2020 to November 2021 on patients who have been treated with TTM following CA. The propensity score matching is proceeded between the lumbar CSF drainage and non-lumbar CSF drainage groups. The good outcome group is defined as a Glasgow-Pittsburgh cerebral performance categories (CPC) scale 1 or 2, and the poor outcome group as a CPC between 3 and 5. Lumbar CSF drainage is initiated when intracranial pressure (ICP) exceeded 15 mmHg in the absence of noxious stimuli at the rate of 10~20 ml/h via a lumbar drainage catheter until ICP is less than 15 mmHg. The magnetic resonance imaging (MRI) is obtained between 72-96 h after return of spontaneous circulation (ROSC) to evaluate the effect of lumbar CSF drainage on attenuation of brain swelling through quantitative analysis of apparent diffusion coefficient (ADC). Multivariate logistic regression and Kaplan-Meier models are built to identify the effect of CSF drainage on the neurologic outcome improvement.

RescueTEE for In-hospital Cardiac Arrest (ReTEECA Trial)
EchocardiographyTransesophageal5 moreReTEECA Trial. Rescue TransEsophageal Echocardiography for In-Hospital Cardiac Arrest. This trial is aimed at studying the utility and interventional outcomes of rescue transesophageal echocardiography (RescueTEE) to aid in diagnosis, change in management, and outcomes during CPR by using a point of care RescueTEE protocol in the evaluation of in-hospital cardiac arrest (IHCA). This is an interventional prospective convenience sampled partially blinded phase II clinical trial with primary outcomes of survival to hospital discharge (SHD) with RescueTEE image guided ACLS versus conventional ACLS.
