Active clinical trials for "Heart Arrest"

In this study, the investigators compared mechanical and manual chest compressions in in-hospital cardiac arrest cases.

While 80 % of all sudden cardiac death (SCD) result from coronary artery disease (CHD) approximatively 2/3 of SCD occur as a first manifestation of the CHD. VF (ventricular fibrillation) is the main cause of SCD in acute coronary syndrome (ACS), and the 2017 ESC Guidelines for the management of acute myocardial infarction, recommended direct admission to the catheterization laboratory in survivors of out of hospital cardiac arrest (OHCA) with criteria for STEMI on the post-resuscitation electrocardiogram (ECG) (Class I, grade B). However, During the past few years, the number of immediate coronary angiography (CA) for suspected ACS in patients presenting an OHCA increased, with a survival rate at discharge in this subgroup of patients better, about 60 to 80% (1). However, the survival rate remains poor in the global population of OHCA and some survivors patients may have neurological sequelles, related to global anoxia consequences or altered quality of life related to cardiac function impairement . While the survival rate at hospital discharge is well known, the investigators have few data on long term outcomes , particularly regarding cardiac and neurological states. Therefore the main objective of this study is to evaluate prospectively, in an observational study, the one-year prognosis of patients with rescuscited OHCA in whom a CA for suspected ACS was performed in the university hospital of Montpellier. Only patients alive at discharged are considered for the follow-up to eliminate the in-hospital mortality . The investigators aim to assess year neurological status using medical questionnaires at one year follow-up(primary end point). The investigators hypothesize that 10% of patients will discharged alive from hospital with severe neurological sequelae at 1 year.Secondary end point will evaluate cardiac status, quality of life and pronostic factors of adverse outcome.

To explore whether the patient's neurological function recovery period is sufficient after successful emergency resuscitation recommended by the current guidelines

Cardiac arrest during pregnancy is rare but may result in poor maternal and fetal outcome. Because of its rare occurrence and ethical issues this topic is not very well studied and many questions pertaining to maternal resuscitation remain unanswered. One of the challenging aspects of cardiopulmonary resuscitation in a term pregnant patient is the ideal positioning during chest compressions. International societies have made recommendations regarding management of pregnant patients during cardiac arrest. They advocate the use of left lateral position with 30 degrees tilt or manual uterine displacement. However these recommendations are not based on high level of evidence. Ultrasound has been used to visualize the change in diameter of great vessels to determine the volume status or adequacy of blood circulation of these patients. This approach can be used to study the adequacy of blood circulation of pregnant patients in different positions. The objective of this study is to compare the change in Inferior vena cava diameter obtained with pregnant women in either the left lateral tilt or in the supine position with a manual uterine displacement, compared to the left lateral position and the supine position. Our hypothesis is that the inferior vena cava diameter obtained in the supine position with manual left uterine displacement would be larger as compared to that obtained with women positioned with a 30-degree tilt.

Background: Cardiac arrest is a life-threatening event. Intensivists are challenged with an increasing number of patients with uncertain neurological outcome following cardiopulmonary resuscitation (CPR). The prognostic value of current biomarkers for neurophysiologic long-term outcome is limited. Hypothesis: We hypothesize that specific brain-derived tissue leakage proteins can be identified to reveal novel, more reliable prognostic biomarkers for good neurological outcome. Methods: This translational study (n=100) is a combination of a prospective basic science study intended to reduce the number of potential plasma biomarker candidates by proteomic shotgun analyses in brain tissue autopsy samples and plasma samples from resuscitated patients (n=10) and a prospective clinical validation study in a large study population (n=90) by high-throughput analyses. Selection of proteomic markers and signature estimation will be performed to discriminate patients with good and poor outcome. Clinical perspective: A structured proteomic analysis approach might identify the best marker out of all proteins liberated during cellular damage.

Cardiovascular disease (CVD) is an important public health problem that affects millions of people worldwide. Associations between risk factors, such as smoking, dyslipidaemia or hypertension, and prevalent CVD are well documented. However, few studies have investigated associations with onset of disease. The initial manifestation of CVD, for example an episode of unstable angina, is important because it influences the prognosis, the quality of life and the management of disease. Furthermore, the extent to which social deprivation, alcohol consumption or atrial fibrillation affects presentation of CVD is poorly understood and deserves further consideration. Most previous studies have considered CVD as a single entity. However, differences in aetiology between coronary phenotypes suggest that risk factors may not be shared across specific coronary phenotypes and their relative importance is likely to differ for each phenotype. Gaining knowledge of these differences could provide insights into the pathophysiology of specific forms of CVD and could eventually lead to modification of recommendations for patient management and disease prevention. We propose to use the linkage of the national registry of coronary events to general practice records in the Clinical Practice Research Database (CPRD), to investigate whether demographic, behavioral, and clinico-metabolic risk factors differentially influence the onset of specific types of CVD.

The purpose of this study is to understand what happens to cerebral metabolism during therapeutic hypothermia for hypoxic brain injury following cardiac arrest.

The purpose of this study is to analyse transitions in cardiac rhythm and hemodynamic variables during resuscitation of patients with in-hospital cardiac arrest.

This is a clinical study based on analysis of video-clip data of endotracheal intubation (ETI) using videolaryngoscope (VL) and clinical data for cardiopulmonary resuscitation patients between 2012.03.01.-2015.02.28. The purpose of this study is to evaluate the appropriate numbers of VL usages for successful ETI at first attempt during cardiopulmonary resuscitation.

It is very important to ensure the tube placement in patients with cardiac arrest and unrecognized misplacement of endo-tracheal tube can lead to morbidity and mortality. In recent pandemic situations such as COVID-19 (Coronavirus disease-19), the number of cases of cardiopulmonary resuscitation with personal protective equipment (PPE) have increased. In those cases, existing methods such as auscultation and chest uprising have to be limited. Quantitative waveform capnography is recommended as the gold standard for confirming correct endotracheal tube placement in the 2010 American HeartAssociation (AHA) Guidelines for Cardiopulmonary resuscitation (CPR) and Emergency Cardiovascular Care (ECC), but it has some well-known limitations in cardiac arrest patients. Ultrasonography is a non-invasive, real-time diagnostic tool commonly used during resuscitation. Especially, tracheal ultrasonography can be performed in real-time when the tube is passed through the trachea or esophagus. Previous prospective studies revealed that tracheal ultrasonography could feasibly and rapidly confirm tracheal intubation during emergency intubation. There have already been several studies comparing the accuracy of tracheal ultrasound and capnography, but there was no study comparing the two tools under the constraints of PPE that is essential in pandemic situations as in this study. This study aimed to determine the accuracy of tracheal ultrasonography in assessing endotracheal tube position during CPR with PPE.
