Active clinical trials for "Heart Arrest"

Early-onset pneumonia after out-of-hospital cardiac arrest is frequent. An association between early-onset pneumonia and an increase in morbidity has been reported in this population. The diagnosis of early-onset pneumonia inpatients with out-of-hospital cardiac arrest may be challenging as diagnosis criteria are unspecific in this setting. On the other hand some studies have reported an association between early antibiotics and better prognosis in patients with out-of-hospital cardiac arrest suggesting that early diagnosis and treatment of pneumonia would benefit to patients. Nonetheless, adminitration of antibiotics to any patients with out-of-hospital cardiac arrest would expose to antibiotic patients without infection and woould participate to increase in antibiotic resistance. Therefore, the PP-ACR study aims to evaluate the impact of a diagnosis algorithm including blinded sampling protected brushes on early-onset pneumonia treatment and patient prognosis after out-of-hospital cardiac arrest.

This study seeks to evaluate, whether patients suffering from cardiac arrest, that can be successfully resuscitated, can be differentiated from those, that cannot be resuscitated, using arterial blood pressure values.

Through this retrospective observational study (over 4 years; period analysed: 1st January 2011 to 31st December 2014), we looked for prognostic factors associated with better survival in refractory cardiac arrest by: assessing the overall survival rate evaluating the frequency of intra et extra-hospital events and by comparing these with the survival rate studying no flow, low flow, rhythm at initial management, troponinemia, lactatemia and blood pH in the different groups.

In this study, we want to find out whether the recognition of cardiac arrest using a smart watch is feasible or not. If this idea is possible, the recognition of cardiac arrest using the smart watch is easy and fast to the witness, like a general person. By using the smart watch, the emergency response system for cardiac arrest and the bystander CPR or BLS is beginning earlier than using conventional cardiac arrest recognition method in field.

Time-limited adaptive responses of thyroid function are common in the critically ill. About 70% of all patients treated on intensive care units develop a so-called non-thyroidal illness syndrome (NTIS) or TACITUS (thyroid allostasis in critical illness, tumours, uraemia and starvation), which is marked by low serum concentrations of the thyroid hormone T3 and other adaptive reactions of thyroid homeostasis. Occasionally, temporarily elevated concentrations of thyrotropin (TSH) and peripheral thyroid hormones are to be observed, especially after cardiopulmonary resuscitation (CPR). However, the available evidence is limited, although abnormal concentrations of thyroid hormones after CPR have occasionally been reported. Aim of the planned study is to investigate the thyrotropic (i.e. thyroid-controlling) partial function of the anterior pituitary lobe immediately after CPR. It is intended to evaluate statistical measures of TSH concentration and peripheral thyroid hormones in de-identified datasets (protocol A). Additionally, a prospective sub-study (protocol B) aims at a more precise description of pituitary and thyroid responses by means of serial investigations in routine serum samples, both immediately after CPR and during the course of ongoing treatment. This includes the evaluation of additional possible predictors, too. Primary endpoint of the study is changed TSH concentration immediately after CPR compared to the TSH value 24 hours later. Secondary endpoint is the relation between thyroid-controlling pituitary function and mortality. A high proportion of patients undergoing CPR will eventually receive iodinated radiocontrast media (e.g. for computed tomography or coronary angiography). This is one of the reasons why early identifying subjects at high risk for possible iodine-induced thyrotoxicosis is important. Increased oxygen consumption of the heart in hyperthyroidism is one of the reasons for high mortality in thyrotoxicosis. Therefore, accurate diagnosis of alterations in the hypothalamus-pituitary-thyroid (HPT) axis is of paramount importance.

CIRCA aims to determine the incidence and outcomes of in-hospital cardiac arrest (IHCA) in UK intensive care units (ICUs) and explore associated risk factors with ICU and hospital survival and quality of survival following hospital discharge.

Somatosensory Evoked Potentials (SSEP) and Pupillary Light Reflex (PLR) are key methods for neurologic prognostication in comatose survivors of cardiac arrest. Both methods have low false positive rates.Though they assess different functions of the brain, they should both be sensitive to severe anoxic/ischemic injury from cardiac arrest. The aim of this observational prospective study with an estimated recruitment of 50 patients is to examine the interrelation between PLR and SSEP. PLR will be assessed by Neurological Pupil index (NPi) and SSEP by the cortical N20 response to stimulation of the median nerve.

This study aims to evaluate the electrophysiological properties of the heart conduction system in patients with unexplained polymorphic ventricular tachycardia (VT) and/or ventricular fibrillation (VF), in patients with specific genetic mutations regarding sudden cardiac death or sudden cardiac arrest, in their family members and in a control cohort. The electrophysiological properties will be measured with the relatively new technique ECG-Imaging (ECGI). Also a National Dutch registry for patients with unexplained polymorphic VT and/or VF and their family members will be created. By combining the data from the registry and the results of ECGI, The investigators hope to identity risk markers for patients at higher risk for apparently idiopathic ventricular fibrillation, and use these for an adapted flow chart for the 'general'population of patients at risk for unexplained polymorphic VT and/or VF. The investigators aim to be able to identify patients before the first arrhythmic event, and aim for better treatment strategies in the future.

An terminated pregnancy is defined as the cessation of cardiac activity before 14 weeks of amenorrhea. This early interruption of gestation can be induced by pathological, traumatic or idiopathic causes. In any case, it remains a physically and psychologically trying event for the woman, the couple as well as for the man. Indeed, the loss of this embryo, which measures only a few millimeters, corresponds to the loss of a child for the triad: woman, man, couple. The termination of this pregnancy is experienced as a bereavement for the future parents. The stopped pregnancy has always been a taboo in the society. The proof being that it was not until the 1980s that this was considered mourning and its psychological consequences were studied. Following these studies, psychological follow-ups are democratized and are thus offered to women. However, when is it men? The investigators have always put the woman at the center of the care process. Which is legitimate. However, the man is often seen as "the person who influences the woman". This default categorization marginalizes the man who would like to be an actor in the care of his partner. In fact, men are increasingly asking to support women in their gynecological care procedures. Unfortunately, for lack of measures put in place. The men are more than abandoned.

Postresuscitation disease is a constellation of disorders related to whole-body ischemia and reperfusion syndrome. It includes hypoxic damage in brain, liver, kidney, heart and other organ. In previous study more than one-third of patients resuscitation from out of hospital cardiac arrest developed renal dysfunction. In acute kidney injury, NGAL is an earlier marker compared with serum creatinine. Cardiac arrest and severe asphyxia result in global brain ischemia. In previous study serum NGAL correlated with hypoxic ischemic encephalopathy in asphyxiated neonate. This study was designed to assess serum NGAL level in postresuscitative patients to evaluate its relation to hypoxic brain injury severity, and its clinical utility for early detection of acute kidney injury in these patients.
