Active clinical trials for "Heart Arrest"

The purpose of this study is to determine whether the blood transcriptome of patients resuscitated after out-of-hospital could be an early predictor of the neurological outcome.

Cardiac arrest is a major health problem that carries a high mortality rate. Substantial research and development have been put into changing the outcome of cardiac arrest and despite the advent of automated external defibrillators (AED), increase in bystander Cardiopulmonary resuscitation (CPR) and automated CPR devices (ACPR), the proportion of patient survival to hospital discharge has only minimally improved. The objective is to investigate safety and performance of the Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) procedure as an adjunct to Advanced Life Support (ALS) for treatment of refractory cardiac arrest.

60,000 people suffer an out of hospital cardiac arrest in the United Kingdom (UK) every year. Bystander cardiopulmonary resuscitation (CPR) rates are dismal (30%) compared with places where CPR education is mandatory for all school children (>50%). Strategies are needed to increase these rates through innovative approaches. Lifesaver (www.life-saver.org.uk) is an immersive interactive programme/application that presents such an opportunity. This study aims to assess the effectiveness of Lifesaver on CPR attitudes, knowledge, skills acquisition and retention in school children. Additionally, it aims to examine whether Lifesaver provides additional benefits in terms of CPR attitudes, knowledge, skills acquisitions and retention in school children when combined with face-to-face BLS training.

Cardiac arrest is a major public health problem, with 700 000 cases per year , and a survival ranging from 4 to 33%. The post- anoxic encephalopathy remains the most serious complication with only a third of survivors . It is due to a series of phenomena involving microcirculation disorders . Cerebral oximetry is a new technique to evaluate the microcirculatory status . To this day it is used in cardiovascular surgery at risk of cerebral hypoperfusion where desaturation of cerebral oximetry is synonymous with ischemia and microcirculatory disorders. Therapeutic hypothermia is the only treatment improves the outcome of patients after extra- hospital cardiac arrest resuscitation . Its mechanisms of action seem to change all the phenomena responsible for microcirculatory reperfusion disorders . Currently it is recommended to practice hypothermia between 32 and 34 ° C. However, a recent study suggests a superiority of hypothermia at 32 ° C rather than 34 ° C. The hypothesis of this study is that cerebral oximetry value will be different in patients subjected to two different levels of therapeutic hypothermia in the aftermath of an extra- hospital cardiac arrest. These data allow a better understanding of the mechanisms underlying the benefit of this technique.

This is a steering group approved substudy to the Target Temperature Management trial (TTM, ClinicalTrials.gov Identifier: NCT01020916). TTM compares the effect of two strictly controlled temperature regimes for survivors of out-of-hospital cardiac arrest. The primary aim of this sub-study is to compare the amount of cognitive impairment in cardiac arrest survivors treated with 33 degrees and 36 degrees and with a matched group of control patients with myocardial infarction. Our secondary aims are: To investigate the impact of cognitive impairment on our patients' ability to participate in society and their health related quality of life. To investigate the relationship between our patients cognitive impairments and their relatives/informants health related quality of life and feelings of burden. To test the hypothesis that the simple cognitive screening battery used in the TTM main trial is sensitive enough to detect all patients with significant cognitive disability.

To determine whether drug treatment of asymptomatic ventricular arrhythmias in post-myocardial infarction patients reduced the incidence of sudden cardiac death and total mortality.

The data of patients undergo extracorporeal cardiopulmonary resuscitation (eCPR) will be collected and analyzed. This study will provide useful information about the indication, the start time and others to improve the outcome of ECPR.

Post-cardiac arrest mortality remains high and proper care after cardiopulmonary resuscitation is an important clinical challenge. This prospective observational cohort aims to (1) identify the factors that affect short-term and long-term survival in post-cardiac arrest survivors and (2) investigate the patients and their families' health-related quality of life and psychological well-being.

The primary aim is to conduct a prospective observational cohort study to analyze the incidence of serious arrhythmic events that occur within 14 days after hospital discharge in patients who had been hospitalized for cardiac arrest caused by acute myocardial infarction. Cardiac arrythmias following hospital dischagre will be detected with Philips ePatch® 2.0 for 14 days.

Extra-hospital cardiac arrest is a major public health problem, with approximately 46,000 cases per year. Nearly 71% of the patients for whom resuscitation was initiated did not present a return of spontaneous circulation on scene and only 29% were transported alive to the hospital. In this context, extracorporeal cardiopulmonary resuscitation (ECPR) by veno-arterial extracorporeal membrane oxygenation has been developed as a second line of treatment according to the latest international guidelines. The selection of eligible patients as well as the timing of initiation of ECPR has long been controversial, but expert recommendations have recently been published. After an out-of-hospital cardiac arrest of cardiological cause, an early ventricular dysfunction has been previously described, more particularly in hemodynamically unstable patients. This dysfunction was associated with greater early in-hospital mortality. There are few data on the medium-term course of left ventricular dysfunction and the largest study addressing this question showed that the severity of left ventricular involvement was associated with greater long-term morbidity and mortality. However, it also found that left ventricular ejection fraction was partially reversible in 29% of the study population. It seems so far, the medium-term evolution of left heart dysfunction had not been described in the context of refractory extra-hospital cardiac arrest treated by ECPR. However, these patients are particularly severe, hemodynamically unstable and potentially at risk of developing long-term sequelae.
