Active clinical trials for "Heart Arrest"

Hypoxic-Ischemic-encephalopathy (HIE) is a severe and frequent neurological complication of successful cardiopulmonary-resuscitation after cardiac arrest (CA). Prognosticating neurological outcomes in patients with HIE is challenging and recent guidelines suggest a multimodal approach. Only few studies have analyzed the prognostic power of the association between instrumental tests and, in addition, most of them were monocentric, retrospective and evaluating only poor outcome.

Theoretical knowledge of cardiopulmonary resuscitation (CPR) is the foundation of being able to perform CPR in a cardiac arrest situation. The knowledge and skills received in training is easily lost and after one year the level is equal to pretraining. International studies regarding knowledge of CPR among healthcare professionals, mostly nurses, show poor results. The knowledge of CPR among Swedish healthcare professionals is poorly studied. The aim of this study was to describe the theoretical knowledge of CPR and self-assessed abilities of performing CPR among healthcare professionals working in four hospitals in Sweden.

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.

Transfontanellar Doppler can measure the velocity at both the carotid artery and the anterior cerebral artery during cardiopulmonary bypass in congenital heart disease patients. This study can provide reference value of appropriate cerebral blood flow velocity during pediatric cardiac surgery.

Proteomics is used to identify prognostic markers after CPR. Additionally neurological outcome should be estimated by specific protein alterations and affections of pathways.

The quality of cardiopulmonary resuscitation (CPR) provided to patients with out-of-hospital cardiac arrest (OHCA) is often suboptimal. There now exist monitors/defibrillators that allow for the measurement and real time feedback of the quality of chest compressions and ventilations. In addition to giving the prehospital provider the benefit of real time CPR quality feedback via voice and visual cues, the CPR quality data acquired using these devices can be utilized as part of an on-going quality assurance/quality improvement program. The first objective of the proposed project is to quantify the quality of chest compressions and ventilations provided in the state of Arizona to patients with OHCA and to determine whether the quality of CPR is related to patient outcome from OHCA. A second objective of this project is to determine whether use of audiovisual feedback improves both CPR quality and patient outcome in the pre-hospital setting.

Patients resuscitated from a cardiac arrest undergo therapeutic hypothermia as a treatment option. Measuring the cardiac output in these patients is sometimes important, but difficult, as these patients require an invasive device for measurement. Recently, a non-invasive device based on pulse-contour analysis of the arterial pulse was developed (the Vigileo). Hypothermia changes the pulse contour, so the performance of the Vigileo in patients with induced therapeutic hypothermia is not known. Therefore we conduct this observational study in which the cardiac output of the patients is measured with the traditional method and the Vigileo simultaneously.

We will conduct a prospective cohort study evaluating the incidence of and optimal risk estimation model for major perioperative cardiovascular events in consecutive patients undergoing noncardiac surgery at the 'Herlev University Hospital'. This national pilot study in Denmark together with other national studies will inform the feasibility of a large prospective international cohort study.

The CASPER will collect systematic clinical assessments of patients and families within the multicenter Canadian Inherited Heart Rhythm Research Network. Unexplained Cardiac Arrest patients and family members will undergo standardized testing for evidence of primary electrical disease and latent cardiomyopathy along with clinical genetics screening of affected individuals based on an evident or unmasked phenotype.

To evaluate whether T Wave Alternans can predict ventricular arrhythmias and sudden cardiac death (SCD) in a prospective epidemiologic natural history study. The prospective epidemiologic pilot study included 550 patients that had left ventricular dysfunction and no history of sustained ventricular arrhythmias. The primary hypothesis tested was whether there was an increased risk of having an arrhythmic event when T Wave Alternans was present in the patient. The secondary aims included comparing risk due to T Wave Alternans between the ischemic patients and non-ischemic patients and assessing whether T Wave Alternans remained an independent predictor of risk upon adjustment for other known risk factors for arrhythmic events such as ejection fraction, ventricular ectopy, NSVT, average NN interval, and RR interval variability. The study approach was a standard epidemiologic surveillance technique. The subject population consisted of individuals with Class I to III heart failure who will underwent a TWA and Holter monitor test and then were followed for up to two years or until arrhythmic events occured.
