Active clinical trials for "Heart Arrest"

The primary aim of the trial is to compare survival to hospital discharge after continuous chest compressions (CCC) versus standard American Heart Association (AHA) recommended cardiopulmonary resuscitation (CPR) with interrupted chest compressions (ICC) in patients with out-of-hospital cardiac arrest (OOHCA). The primary null hypothesis will be that the rate of survival to hospital discharge is not affected by use of continuous compressions with passive or positive pressure ventilation (intervention group) versus CPR with compressions interrupted for ventilation at a ratio of 30:2 (control group).

The investigators hypothesised that the neuroprotective effects of erythropoietin and its analogues could lead to an improve outcome after cardiac arrest. To test this hypotheses, the investigators designed a randomized, multicentre, simple blind trial in which all participating patients will be receive usual treatments and 50% of them will also receive a high dose of epoetin alpha (an analogue of erythropoietin) in an "add on" fashion. The main end point will be the proportion of patients in each arm who will reach at day 60 the best level of recovery, using a 5 level score.

Experimental studies and previous clinical trials suggest an improvement in mortality and neurological function with hypothermia after cardiac arrest. However, the accrued evidence is inconclusive and associated with risks of systematic error, design error and random error. Elevated body temperature after cardiac arrest is associated with a worse outcome. Previous trials did not treat elevated body temperature in the control groups. The optimal target temperature for post-resuscitation care is not known. The primary purpose with the TTM-trial is to evaluate if there are differences in all-cause mortality, neurological function and adverse events between a target temperature management at 33°C and 36°C for 24 hours following return of spontaneous circulation after cardiac arrest.

The purpose of this study is to test the possible neuroprotective effect of early high dose erythropoietin alpha after out of hospital cardiac arrest (OHCA).

The purpose of this study is to determine whether adding interactive video communication to dispatch instruction improves the quality of bystander cardiopulmonary resuscitation in simulated cardiac arrests.

Cardiac arrest is a sudden, unexpected loss of heart function. Therapeutic hypothermia, in which the body's temperature is lowered and maintained several degrees below normal for a period of time, has been used to successfully treat adults who have experienced cardiac arrest. This study will evaluate the efficacy of therapeutic hypothermia at increasing survival rates and reducing the risk of brain injury in infants and children who experience a cardiac arrest while out of the hospital.

The investigators hypothesised that cyclosporine A administration at the onset of cardiopulmonary resuscitation, by inhibiting the mitochondrial permeability transition pore, could prevent the post cardiac arrest syndrome and improve outcomes.

We propose to randomize automatic external cardioverter/defibrillators (AECD) in patients who are at high risk for life-threatening abnormal heart rhythms (arrhythmias) and are admitted to the telemetry ward, all other treatments being constant including cardiopulmonary resuscitation. We hypothesize that the automatic, rapid, accurate and specific diagnostic and therapeutic technology used in AECDs will further increase the rate of survival in patients with cardiac arrest through rapid and automatic defibrillation, independent of operator initiation, as compared to standard cardiopulmonary resuscitation initiated by healthcare providers.

Intravenous epinephrine has been part of the guidelines for cardiopulmonary resuscitation since the start. It improves outcome in animal studies, but has never been investigated in a controlled study in humans. Epidemiologic data indicate that it is an independent negative predictor for survival. If this is true in a controlled randomized study, it could be due to effects of the drug itself or more likely due to reduced quality of chest compressions and ventilations due to the time spent on placing an I.V. needle and injecting drugs.

Sudden cardiac death is a major health problem in the western world. In Europe alone nearly 300 000 patients are affected annually. The majority of victims suffering from an Out-of-Hospital Cardiac Arrest (OHCA have an initial cardiac rhythm that can be treated by means of defibrillation. In most emergency medical systems (EMS) time to defibrillation is too long and survival averages 10 %.However, when laymen operated Automated External Defibrillators (AEDs) are used within the first minutes, 7 out of 10 may survive. The aim of "The Scandinavian AED and Mobile Bystander Activation" (SAMBA) trial is to evaluate if a Mobile Phone Positioning system and a smartphone application will increase the proportions of patients with an attached Automated External Defibrillator (AED) before arrival of the Emergence Medical System (EMS). Mobile phone technology and a smartphone application will be used identify and recruit nearby CPR-trained lay people and automated external defibrillators (AEDs) to patients suffering out-of-hospital cardiac arrest (OHCA). The system is currently running in Stockholm Sweden and in the Gothenburg region.
