Filter by:Sudden cardiac death (SCD) is a major cause of mortality in industrialized countries and represents a major health issue. The survival rate after out-of-hospital cardiac arrest (OHCA) is only 10-15%, regardless of first recorded rhythm. Prior heart disease is a major risk factor for sudden cardiac arrest (SCA), and coronary artery disease (CAD) is the most common underlying cause. A better understanding of pathophysiological mechanisms occurring during cardiac arrest (CA), earlier diagnosis of underlying cause as well as identification of risk factors related to CA may improve patient treatment and increase survival. In our out-of-hospital cardiac arrest (OHCA)-study, we intend to investigate whether biomarkers, such as copeptin, hs-cTnT and NT-proBNP in addition to clinical evaluation may improve risk stratification and supply information related to pathophysiology. Furthermore, we intend to gather additional pathophysiological information related to coagulation activation in CA and cardiopulmonary resuscitation (CPR), as intravascular thrombosis may impair microcirculation and reduce end-organ blood flow which is associated with a poor prognosis. We intend to study coagulation activation during and immediately after SCA with regard to outcome, and assess the contribution of the intrinsic system, measured together with that of the extrinsic system. Low levels of n-3 fatty acids (FA) are reported as a risk factor for SCD. Red blood cell eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) may serve as a useful surrogate of cardiac omega-3 fatty acid status. The exact mechanism by which FAs might protect against serious cardiac arrhythmias is not known, but they are expected to exert a membrane stabilizing effect during an ischemic episode. In our study we intend to evaluate the association between ventricular fibrillation (VF) and the content of EPA and DHA in red blood cells. Furthermore, as vitamin D is associated with n-3 FAs in the diet, we also aim at investigating the association between 25-hydroxy (OH)-vitamin D and VF.
The aim of this study is to evaluate the prognostic value of the suppression ratio monitored by Bispectral Index for prediction of neurologic outcome after cardiac arrest. All patient admitted to our intensive care unit after a cardiac arrest are included. The results of the suppression ratio will be collected in the 6 first hours of admission. We will evaluate the link between suppression ratio and cerebral performance category score collected at three months.
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.
A prospective randomized controlled trial studying the ordering of palliative care consultations in the emergency department (Ig) versus later palliative care consultations in the hospital--ICU or hospital ward(Cg). Patients will be randomly allocated to Ig or Cg with a 1:1 ratio.
This study includes comatose survivors of out-of-hospital cardiac arrest treated with 24 hours or 48 hours of targeted temperature management. The overall aim is to evaluate the importance of plasma complement protein concentrations in patients resuscitated after out-of-hospital cardiac arrest and treated with 24 hours or 48 hours of targeted temperature management. The specific aim is to evaluate: - the concentration of plasma lectin pathway proteins the first, second and third day after cardiac arrest - the relation between concentration of plasma lectin pathway proteins and mortality - if prolonged targeted temperature management influences the concentration of plasma lectin pathway proteins This study is a sub-study to the trial entitled: "Time-differentiated targeted temperature management (TTH48) (ClinicalTrials.gov Identifier: NCT01689077)" The following Complement Lectin Pathway proteins will be measured: Mannan-Binding-Lectin, M-ficolin, H-ficolin, CL-L1, MASP-1, MASP-2, MASP-3, MAp19 and MAp44.
This is a sub-study to the Time-differentiated Therapeutic Hypothermia (TTH48, ClinicalTrials.gov Identifier: NCT01689077). TTH48 compares 24 with 48 hours of therapeutic hypothermia at a target temperature of 32-34°C in survivors of out-of-hospital cardiac arrest. The overall aim of this sub-study is to examine the hemostasis in patients resuscitated after cardiac arrest and treated with 24 and 48 hours of therapeutic hypothermia Our specific aims are: - To investigate the whole blood coagulation using the rotational thromboelastometry. - To investigate the function of platelets
The quality of cardiopulmonary resuscitation (CPR) has been identified as an important determinants for patient survival, yet many studies revealed poor CPR guidelines compliance in real-life practice for both health care providers and lay persons. Common shortcomings identified include an insufficient number of chest compression, too rapid lung inflations, and too much hands-off time. The poor quality of CPR is associated with lower survival rate. Besides, some other problems could be found during resuscitation, such as prolonged intubation time, delayed first shock delivery or unsteady drug delivery interval. These problems can't be blamed on the only person but the teamwork. Certain measurements could improve the performance of the resuscitation team, such as audio prompt or checklist. Methods proposed and improvised to improve the quality of CPR have included CPR assisted devices, automatic driven devices or audio prompt system. However, some of these methods are hardly incorporate with the original resuscitation process since it could be an extra workload. Therefore, the investigators try to provide an digitized checklist combined with visual and audio alarming system, which could not only minimize the workload of chart recording but also remind the team to perform essential procedures in time. Information gained from a video-recording evaluation system had been employed to improve the resuscitation skills. The improvement of resuscitation quality also could be found through video-recording after certain intervention. It can also avoid the interference of the resuscitation and find out other harmful factors to CPR quality.
Study of heterogeneity in associations between heart rate and the initial presentation of 12 cardiovascular diseases.
Study of heterogeneity in associations between social deprivation and the initial presentation of 12 cardiovascular diseases.
The association between alcohol consumption and cardiovascular disease (CVD) has mostly been examined using broad endpoints or cause-specific mortality. The purpose of our study is to compare the effect of alcohol consumption in the aetiology of a range of cardiovascular disease phenotypes.
