Cardiac Arrest

Purpose & organization

The purpose of The Cardiac Arrest Network is to gather researchers with common interests in all aspects of research within the field of resuscitation after cardiac arrest.

The Cardiac Arrest Network represents different areas of specialization and professions, among these are students, nurses, prehospital employees and physicians. All of them contribute and support the research field of resuscitation after cardiac arrest.

The COCA trial is a randomized, double-blind, placebo-controlled trial evaluating calcium chloride (CaCl) as an intra-arrest intervention for patients with out-of-hospital cardiac arrest. The primary aim of the project is to test whether CaCl – in addition to standard treatment – can improve the proportion of patients regaining spontaneous circulation at hospital arrival.

The study is a randomized, controlled, simulation study comparing two different strategies for cardiopulmonary resuscitation performed by laypersons in a setting of multiple rescuers present. A total of 160 laypersons will be included.

This PhD project aims to improve the efficacy and safety of electrical direct current cardioversion of atrial fibrillation. The studies are designed as randomized clinical trials to provide data on the clinical best-practise for cardioverting atrial fibrillation. The studies aim to investigate cardioversion waveform, energy levels and electrode positions for cardioversion.

The studies are planned to actively enroll patients between 2016 – 2020.

In this observational cohort study, we aimed to compare patient characteristics, cardiac arrest event characteristics, and outcomes for in-hospital and out-of-hospital cardiac arrest patients in Denmark. The primary endpoint was 30-day survival. Secondary outcomes were return of spontaneous circulation and one-year survival.

This mixed-methods simulation study aims to investigate if structural and functional components of commercial AEDs can be improved with more user-friendly designs and instructions, and whether this can shorten time to defibrillation by laypersons.

Every year around 2,500 people suffers a cardiac arrest in Danish hospitals and less than one out of three will survive. The aim of this project is to optimize the use of automated external defibrillators during in-hospital cardiac arrest. The project will contribute with important knowledge about why automated external defibrillators are not always used during in-hospital cardiac arrest and which factors we can improve to save more lives. If we can improve the chance of surviving an in-hospital cardiac arrest by 1 percentages point , we can save 25 more lives every year.

Socioeconomic factors may influence outcomes through multiple mechanisms including difference in co-morbidities and differential treatments including less aggressive care.

However, little is known about the impact of socioeconomic factors in patients with in-hospital cardiac arrest both in Denmark and internationally. We wish to assess the relationship between socioeconomic factors and treatments and outcomes for patients with in-hospital cardiac arrest in Denmark. Identifying such relationships will facilitate interventions to improve equality in treatment and outcomes.

The project aims to determine whether external administration of ubiquinol (reduced coenzyme Q10) increases physiological ubiquinol levels and decreases markers of neurological injury.

Vasopressin and Methylprednisolone for In-Hospital Cardiac Arrest (VAM-IHCA) - A Randomized, Double-Blind, Placebo-Controlled Trial.

This study aims to improve patient survival and neurological outcome of cardiac arrest. The VAM-IHCA trial is a national Danish study that has the potential to change international guidelines for treatment of cardiac arrest.
