Active clinical trials for "Death"

Description of the decision making process as well as the practices of end of life care in an ICU of a German university hospital during the period when changes of German legislation occurred.

Sudden cardiac death remains one of the major leading causes of death. Therapeutic hypothermia is a validated standard procedure to avoid or minimize cognitive deficits after cardiac arrest. To assess the efficiency of different cooling methods and further improve these methods, the investigators collected blood samples to measure the neuron specific enolase (NSE) in patients treated with invasive cooling as compared to patients treated with non-invasive cooling.

The purpose of this study is to determine whether waveforms of the intracardiac electrograms, acquired through an ICD, can be used: to predict malignant ventricular arrhythmias, requiring appropriate ICD therapies, and to predict progression of heart failure in patients with ICD.

The purpose of this study is to use the BIS monitor to assess the degree of consciousness in pre-terminal palliative patients admitted to our palliative care unit and to ascertain if this tool provides a more accurate assessment of consciousness in this specific group of patients than clinical observation of consciousness and the use of sedation scales. We hypothesize that the measured BIS results provide a more accurate assessment of the patient's level of consciousness than routine clinical observation or the use of sedation scales.

Worldwide three million people a year die from sudden cardiac death (SCD). In most cases there is no warning and the heart is stopped by a sudden arrhythmia. We know that some people are at high risk of sudden cardiac death and can prevent their deaths with an implantable cardioverter defibrillator (ICD) that is implanted in a minor operation. However, most people who die from sudden cardiac death are not found to be at high risk by our current risk markers and 40% of the people who have ICDs do not have therapy within the first 4 years after implant. We need new and better ways of identifying people who are at high risk of sudden cardiac death so that we can prevent their deaths with ICDs. Our understanding of the electrical signals in the heart has increased considerably in recent years; in no small part this is due to our Principal Investigator Professor Andre Ng's basic science work. This study aims to take the understanding of action potential duration (APD) restitution gained through our work and other studies in humans and in computer simulations and translate it into a fresh way of assessing risk of sudden cardiac death. This study will carefully examine electrical activity, using APD restitution, in the hearts of patients who are having ICDs fitted because of their high risk of sudden cardiac death and combine this with a detailed heart scan, assessment of autonomic nervous system and gene expression data. We will then follow these patients up to see who benefits from their ICD. This wide ranging information will give us as complete a picture as possible of the factors that cause sudden cardiac death. We hope to use this to identify better predictors of sudden cardiac death. The study hypotheses are as follows: Primary Regional Restitution Instability Index (R2I2) will be significantly higher in patients reaching the endpoint of ventricular endpoint / sudden cardiac death than in those not. An R2I2 cut-off of 1.03 will partition patients into high and low risk groups. Secondary Peri-infarct zone mass in grams will be significantly higher in patients reaching the endpoint of ventricular endpoint / sudden cardiac death than in those not.

It is required to establish an adequate definition of delayed graft function in deceased donor kidney transplantation. We attempt to compare various definitions of delayed graft function and find the definition that can predict graft function survival best in deceased donor kidney transplantation.

Occupation stress can be the risk factors of early embryonic death

OBJECTIVES: I. Assess and compare the incidence and severity of cardiorespiratory events documented by home monitoring in infants at increased epidemiological risk for sudden infant death syndrome (SIDS). II. Determine the antecedent medical, demographic, physiologic, and behavioral characteristics that predict the incidence of cardiorespiratory events documented by home monitoring.

The current COVID19 pandemic has afflicted almost the whole globe. The stress related to the pandemic, not the direct virus-related injury, can be potentially associated with acute cardiovascular events due to a large list of physical and psychosocial stresses. This study is a cross sectional study that will enroll patients evaluated during the COVID19 pandemic period for acute cardiovascular events.

The overall aim of this study is to improve our understanding of the effects of the build-up of amyloid deposits in the heart, in particular, our understanding of the risk of abnormal heart beats, or rhythms, associated with people with cardiac (heart) amyloidosis. Symptoms such as palpitations (fast, strong or irregular heart beat) and blackouts are common in people with cardiac amyloidosis, but there is not enough information on what causes this. At present, there is also not enough information on when they occur, how often they happen, and which patients are at risk of having serious, life-threatening types of abnormal heart rhythms. Some of these abnormal heart rhythms can be treated with medicine; others need electronic devices (e.g. pacemakers) implanted or inserted in the heart to prevent serious harm. The information on when is the best time to implant these life-saving devices remains limited. In this study, a small device known as an implantable loop recorder (ILR) will be implanted under the skin on the chest wall to continuously monitor participants' heart rhythm. This will help us answer some of the questions about what causes the abnormal heart rhythms, when they happen, and which patients are particularly likely to have them. Furthermore, it may help us to identify earlier, rather than later, those who are at risk of developing abnormal heart rhythms. This may lead to improvements in the care of people with cardiac amyloidosis in the future. Participants may not directly benefit from taking part in this study; however, there is a chance that the ILR may reveal heart rhythm abnormalities in some participants which might not be picked up otherwise, and so may lead to a change in their treatment.
