Public access defibrillation initiatives make automated external defibrillators available to the public. This facilitates earlier defibrillation of out-of-hospital cardiac arrest victims and could save many lives. It is currently only used for a minority of cases. The aim of this systematic review was to identify barriers and facilitators to public access defibrillation. A comprehensive literature review was undertaken defining formal search terms for a systematic review of the literature in March 2017. Studies were included if they considered reasons affecting the likelihood of public access defibrillation and presented original data...

At abnormally elevated levels of intracellular Ca(2+), mitochondrial Ca(2+) uptake may compromise mitochondrial electron transport activities and trigger membrane permeability changes that allow for release of cytochrome c and other mitochondrial apoptotic proteins into the cytosol. In this study, a clinically relevant canine cardiac arrest model was used to assess the effects of global cerebral ischemia and reperfusion on mitochondrial Ca(2+) uptake capacity, Ca(2+) uptake-mediated inhibition of respiration, and Ca(2+)-induced cytochrome c release, as measured in vitro in a K(+)-based medium in the presence of Mg(2+), ATP, and NADH-linked oxidizable substrates...

BACKGROUND: Each year, about 500,000 people suffer a cardiac arrest (either out-of-hospital or in-hospital) in the USA. Although significant improvements in survival have occurred through the implementation of complex high-quality protocols of care, global costs related to such management are not clearly described. METHODS: We will undertake a systematic review of the published literature on costs related to the acute phase of cardiac arrest management (from collapse to hospital discharge)...

The work of a hospital's medical staff is safety critical and often occurs under severe time constraints. To provide timely and effective cognitive support to medical teams working in such contexts, guidelines in the form of best practice workflows for healthcare have been developed by medical organizations. However, the high cognitive load imposed in such stressful and rapidly changing environments poses significant challenges to the medical staff or team in adhering to these workflows. In collaboration with physicians and nurses from Carle Foundation Hospital, we first studied and modeled medical team's individual responsibilities and interactions in cardiac arrest resuscitation and decomposed their overall task into a set of distinct cognitive tasks that must be specifically supported to achieve successful human-centered system design...

Hypothermic machine perfusion (HMP) effectively reduces ischemia‑reperfusion injury (IRI) in livers donated after circulatory death (DCD) when compared with cold storage (CS). However, the underlying mechanisms remain unclear. The current study aimed to investigate the cellular mechanisms by which HMP ameliorates the inflammatory response during IRI. Adult male Sprague‑Dawley rat livers were exposed to 30 min of warm ischemia following cardiac arrest and preserved by CS or HMP for 3 h (n=3 per group)...

BACKGROUND: Targeted temperature management (TTM) is often used in neurocritical care to minimize secondary neurologic injury and improve outcomes. TTM encompasses therapeutic hypothermia, controlled normothermia, and treatment of fever. TTM is best supported by evidence from neonatal hypoxic-ischemic encephalopathy and out-of-hospital cardiac arrest, although it has also been explored in ischemic stroke, traumatic brain injury, and intracranial hemorrhage patients. Critical care clinicians using TTM must select appropriate cooling techniques, provide a reasonable rate of cooling, manage shivering, and ensure adequate patient monitoring among other challenges...

The American College of Cardiology/American Heart Association guidelines include a Class 1 recommendation to initiate therapeutic hypothermia (TH) in comatose patients with out-of-hospital cardiac arrest (OHCA) with an initial shockable rhythm who have achieved return of spontaneous circulation. There is also a Class 1 recommendation for immediate angiography in these patients whose initial electrocardiography shows ST-elevation myocardial infarction (STEMI). However, due to a lack of clinical trials evaluating these patients who have received both percutaneous coronary intervention (PCI) and TH, controversy remains regarding whether the two can be safely combined...

BACKGROUND AIMS: Light chain (AL) amyloidosis is a protein misfolding disease characterized by extracellular deposition of immunoglobulin light chains (LC) as amyloid fibrils. Patients with LC amyloid involvement of the heart have the worst morbidity and mortality. Current treatments target the plasma cells to reduce further production of amyloid proteins. There is dire need to understand the mechanisms of cardiac tissue damage from amyloid to develop novel therapies. We recently reported that LC soluble and fibrillar species cause apoptosis and inhibit cell growth in human cardiomyocytes...

BACKGROUND: Despite their wide use in the prehospital setting, randomized control trials (RCTs) have failed to demonstrate that any antiarrhythmic agent improves survival to hospital discharge following out-of-hospital cardiac arrest. OBJECTIVE: To assess the use of antiarrhythmic drugs for patients experiencing out-of-hospital cardiac arrest (OHCA). METHODS: Electronic searches of Medline, EMBASE and Cochrane Central Register of Controlled Trials were conducted and reference lists were hand-searched...

AIM: To investigate the epidemiology and outcomes of cardiac arrests associated with opioid overdoses. Recent data suggest that drug overdoses are responsible for more deaths than motor vehicle crashes or firearms in the United States each year, with opioids being involved in majority of drug overdose deaths. Despite the potential for opioids to cause cardiac arrest, few studies have examined this association. PATIENTS AND METHODS: Using data from National (Nationwide) Inpatient Sample database from years 2000-2013, we identified hospitalizations with drug overdoses using ICD-9-CM codes...

A 26-year-old woman, 12 days in postpartum, developed recurrent syncope and cardiac arrest. Her ECG revealed QT-prolongation associated with LQT2-specific T-U wave patterns, T wave alternans, long QT-dependent torsade de pointes (TdP) and ventricular fibrillation (VF). She also had intermittent LBBB (80bpm) on alternate beats and RBBB at sinus tachycardia (113bpm). Family genotyping revealed a novel de novo missense mutation G604C of KCNH2. Propranolol slowed heart rate and further prolonged QT interval (610ms) that caused TdP recurrence...

Aims: Delay in administration of epinephrine is associated with decreased survival among children with in-hospital cardiac arrest with an initial non-shockable rhythm. Whether this association is applicable to paediatric out-of-hospital cardiac arrest (OHCA) population remains unknown. We aimed to determine whether time to epinephrine administration is associated with outcomes in paediatric OHCA. Methods and results: This was a nation-wide population-based study of paediatric OHCA in Japan from 2005 to 2012 based on data from the All-Japan Utstein Registry...
