Aim:
The aim of this study was to describe patient characteristics, event characteristics, and outcomes for patients with in-hospital cardiac arrest in Denmark.
Methods:
Data was obtained from DANARREST. DANARREST is a nationwide registry that covers all in-hospital cardiac arrests in Denmark with a clinical indication for cardiopulmonary resuscitation (i.e. without a prior "do-not-resuscitate" order).
Results:
A total of 4069 adult in-hospital cardiac arrests were registered between January 1st, 2017 and December 31st, 2018. The median age was 74 years (quartiles: 65, 81) and 37% were female. 71% had a non-shockable rhythm and the presumed etiology was primarily non-cardiac (57%). A total of 2180 patients (53.8%) achieved ROSC, with an additional 36 patients (0.9%) receiving extracorporeal cardiopulmonary resuscitation. At 30-days 1124 patients (27.8%) were alive. Of cardiac arrests from 2017, 404 patients (20.0%) survived to 1 year after the cardiac arrest. The incidence of adult in-hospital cardiac arrest in Denmark was estimated at 1.8 per 1000 admissions or 0.6 per 1000 in-patient days.
Conclusion:
In-hospital cardiac arrest occurs in at least 2000 patients each year in Denmark with a 30-day survival of approximately 28%. The establishment of a national registry for in-hospital cardiac arrest in Denmark will allow for quality improvement and research projects.

Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
01:19Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
01:29Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...
