Active clinical trials for "Death, Sudden"

Antipsychotics may be associated to life-threatening arrhythmias and sudden cardiac death. This is the fist study to estimated the arrhythmic burden using long-term monitoring by implantable loop recorder in patients treated with antipsychotics.

Sympathetic tone is important in cardiac arrhythmogenesis. The simultaneous recording of sympathetic nerve activity (SNA) and electrocardiogram (ECG) was obtained by invasive method. The purpose of this protocol is to further develop this recording method to turn it into a new non-invasive tool for arrhythmia prediction and detection. This method may also be useful in validating the results of surgical procedures aimed at sympathetic denervation

Assessment of the psychological benefit of the proposition by prehospital medical team of a sudden death counselling on family members of sudden death victims.

Sudden death is a public health problem with more than 300,000 cases per year in USA and 40,000 cases per year in France. Moreover, despite all recent therapeutic improvements (therapeutic hypothermia, new techniques of resuscitation…), the prognosis remains drastically poor and less than 50% of the patients admitted alive at hospital will survive to the event at 1 year. Outside all medications and technical care to improve patient prognosis, a psychological evaluation looks also critical to detect the occurrence of a "post traumatic stress syndrome". In fact, along with the event severity, a variable period of amnesia related to coma may favor the occurrence of such a syndrome and psychological issues, which at the end may lead to impairment of patient quality of life. Previous studies have evaluated the impact of an intensive care unit diary on psychological distress in patients and relatives in the context of severe traumatisms. Such an evaluation has however never been done in the specific setting of sudden death and the frequency of this syndrome is unknown in this context. Aim The aim of the present study is to evaluate the impact of an intensive care unit diary on the occurrence of a "post traumatic stress syndrome" after a sudden death. Secondary objectives To evaluate the frequency of the occurrence of a "post traumatic stress syndrome" and other psycho traumatic symptoms after sudden death To evaluate the impact of an intensive care unit diary on the severity of this syndrome, psycho traumatic symptoms, and psychopathologic comorbidities To evaluate the impact of the diary on psycho traumatic symptoms and their severity in patient's relatives To evaluate the satisfaction of the patients and their relatives regarding medical cares in both groups (with and without diary) Comparison of nurse diagnostic (psychological distress) and diagnostic made by dedicated personal with a specific formation in psychology Qualitative evaluation of the diary Evaluation of the paramedical feeling before and after the diary input in practice

Background: People with sickle cell disease (SCD) have problems with their heart, brain, kidneys, liver, and lungs as they age. These problems may improve after transplant. Researchers want to learn how and why this happens. Objective: To study the benefits of treatments that are intended to cure SCD. Eligibility: People aged 18 and older with SCD who are either receiving curative therapy in the next 3 months or don t have any plans to receive a curative therapy in the next 2 years. Design: At their first visit, participants will be screened with their medical history and a physical exam. Participants will then have a baseline visit. This will take about a week to complete and will include: Blood and heart tests MRI of the brain, heart, and lungs. Participants will lie on a bed that will move into the MRI scanner. Special padding may be placed around their head to keep it still. Interactive games. Participants will complete computer games that test memory, attention, problem solving, language, spatial orientation, processing speed, and emotion. Questionnaire rating quality of life Iothalamate test. An IV catheter will be placed into a vein. A contrast agent will be injected through the IV. Blood will then be collected at different time points. Lung function tests and a 6-minute walk test Vibration controlled transient elastography. A probe placed on the abdomen will measure liver scarring. DOS test. A light attached to the finger or toe will measure blood oxygen. Participants will have an end-of-study visit about 2 years after their baseline visit. This will include repeats of the baseline visit tests.

CHAOS is based on the investigator's new and exciting results from pre-clinical and large longitudinal multi-center observational clinical studies of critically ill patients and asymptomatic community-based adults with little or no advanced disease. By integrating approaches from the physical, biological, computational, statistical and clinical sciences, this observational study will test the hypothesis that early diagnosis of subclinical signatures of critical illness encoded within physiological signals complements conventional clinical predictors by providing unique prognostic insight. The primary goal is to reduce mortality, morbidity and complications by early identification of individuals with brewing subclinical critical illness and adverse events before overt clinical presentation (e.g., cardiac arrest, arrhythmias, hemorrhage, respiratory failure, circulatory collapse). This will provide the necessary lead time for healthcare providers to deliver early, more effective and/or preventive therapies. Through innovative approaches, CHAOS also meets the challenge of medical errors to reduce missed diagnosis, misdiagnosis, preventable harm and variability in provider adherence to best practice guidelines. The goal is to validate predictive algorithms and identify subclinical signatures of illness, ranging from asymptomatic adults in the community to very sick patients in the hospital. The overall goal is to make healthcare more precise, effective, efficient, safe and timely while reducing costs, preventable harms and adverse events.

The overall hypothesis of this study is that subtle interactions between structural (substrate) and functional (trigger) abnormalities of the heart, some of which are genetically-determined, can be used to identify patients at high risk of sudden cardiac death (SCD). Such information may be used to better define patients most likely to benefit from replacement of an internal defibrillator (ICD). The prospective, observational study to enroll, categorize and follow patients who receive an ICD pulse generator replacement for primary prevention of SCD (PROSe-ICD) was established to : to gain a better understanding of the biological mechanisms that predispose to SCD to develop readily determined clinical, electrocardiographic, genetic and blood protein markers identify patients with an increased risk of dying suddenly

The purpose of this pilot feasibility study is to evaluate the ability of the Perfusion Index to predict the return to spontaneous circulation of the out-of-hospital cardiac arrest patient during cardiopulmonary resuscitation. The performance of the perfusion index will also be compared to the current gold standard, end-tidal CO2 (EtCO2).

A multi-centre observational cohort trial to identify Magnetocardiography (MCG) parameters in the prediction of future ICD therapy. To show a correlation between Arrhythmogenic features on MCG and future ICD therapies seen on ICD interrogation of patients at risk of SCD.

The purpose is to increase the understanding of the characteristics, circumstances, medical histories and pathologies of children from ages 11 months through 18 years who have died suddenly and unexpectedly, and in some instances, without explanation. The SUDC Registry and Research Collaborative will analyze cases of sudden unexpected deaths in these children to understand risk factors and causes, and develop preventative measures.
