Filter by:Congestive heart failure (CHF) represents a major health care concern in the United States. Currently, risk stratification of sudden cardiac death and the need for implantable cardioverter-defibrillator (ICD) placement are essentially dependent upon assessment of left ventricular ejection fraction (LVEF). Nevertheless, the predictive value of LVEF is suboptimal, alternative testing for risk assessment for the development of sudden cardiac death in the heart failure population is desirable. At the genome level, the investigator has focused on the role of SCN5A gene mutations in arrhythmogenesis. Lymphocyte SCN5A mRNA processing may serve as a surrogate marker to assess SCN5A function at the cardiac level and may correlated with arrhythmic risk in high risk populations. This study will determine if SCN5A variant levels are predictive of appropriate ICD therapies in patients with a newly implanted ICD.
Death rate in anesthesia is one of the most valuable methods to assess the safety of anesthesia practice among different types of patients. In this study, the investigators will follow the death among patients who underwent surgery under anesthesia whether regional or general over the next two years from 2016 to 2018.
Death rate in anesthesia is one of the most valuable methods to assess the safety of anesthesia practice among different types of patients. In the investigators study, the investigator will review the death rate in anesthesia whether regional or general over the past five years from 2010 to 2014, by examining the patients records from the hospital database.
The implantable-cardioverter defibrillator (ICD) is a small medical device used to treat dangerously fast and potentially life-threatening heart rates. For patients at risk, the ICD can detect an abnormal rhythm and provide life-saving therapy by delivering a shock. ICD therapy has risks and benefits that should be weighed from each patient's perspective. An ICD battery needs to be surgically replaced 4 to 7 years to ensure ongoing function. At present, the majority of these batteries are automatically changed without eliciting patients' preferences. There is a need for a better way to engage with patients. Patients want to be involved in their healthcare decisions, yet more than half of patients with an ICD do not know that ICD replacement is optional. To ensure that patients are receiving treatment that they value and want, members of the interprofessional team should ensure that treatment decisions align with patients' expectations, values and preferences. This rests on the principle of shared decision making in which members of the healthcare team and patients deliberate together to arrive at a decision which best reflects the preferences and values of the patient. To facilitate the achievement of this goal, a patient decision aid (PDA) can be used. As a result, the investigators developed PDA for ICD replacement. The purpose of this feasibility trial is to collect preliminary data to test the feasibility of conducting a larger trial, and to evaluate the PDA for its acceptability and ease of use. Eligible and consented participants facing ICD replacement will be randomized to receive the decision aid or to usual care. The investigators will assess if this decision aid can improve participants' knowledge on ICD therapy and the replacement surgery, increase patients' perceived involvement in the decision, and determine whether their actual choice reflects their personal values.
This study is an observational study to determine predictors of sudden cardiac death or appropriate ICD therapy in patients with non-ischemic cardiomyopathy. Patients will be followed for 36 months for the occurrence of sudden cardiac death
This research study includes patients ages 1 to 25 years old with Lamin A/C related muscular dystrophy (LMNA-MD). The goal of this study is to evaluate how the heart is affected in children and teens with LMNA-MD. The evaluation includes an echocardiogram, an electrocardiogram, an electrophysiological study and the implantation of a subcutaneous ECG holter monitor.
Cardiac arrest (CA) affects approximately 40,000 people in France. It is still a major cause of death in a young population. Management of CA is defined by international recommendations, detailed by learned societies in each country. It includes several links that are interconnected for its optimisation. Despite all these improvements, no progress, or little has been made in the survival of CA victims over the past few years in industrialised countries, and the survival rate in France is 3% to 5%. Refractory cardiac arrest is defined as failure, after 30 minutes of specialised resuscitation. It used to be the standard to admit that there was no hope of spontaneous cardiac activity and satisfactory neurological recovery after this period, except in cases of CA with neuroprotection (intoxication, hypothermia). External circulatory support such as "extracorporeal membrane oxygenation" (ECMO) makes it possible to replace the circulatory activity of the myocardium and the respiratory activity of the lungs. In in-hospital cardiac arrest (CA) some teams use ECMO with an improvement in the survival rate of 20% in comparison to standard resuscitation. This use demonstrates the possibility of neurological recovery independent of the recovery of spontaneous cardiac activity which can be differed. These results encouraged the use of ECMOs in cases of out-of-hospital refractory cardiac arrests. Patients who are victims of CA are resuscitated for 30 minutes on the spot where the CA occurs. They are then transferred to a specialised centre. The significant improvement in survival noted in in-hospital CAs was not observed in the French series of studies concerning out-of-hospital CAs. This survival is currently estimated at 4%. This difference can be partly explained by the difference in time between the beginning of cardiac massage and the implementation of circulatory support by ECMO ("low flow" period). This time period is directly correlated to survival. To demonstrate the superiority of this strategy in terms of survival, investigators would like to conduct a randomised comparative study of two strategies: 1) installation of an ECMO between the 20th minute to the 30 minute of CA, directly at the site of the CA, by emergency physicians and/or specifically trained resuscitators 2) On-site resuscitation optimised with secondary transfer to the hospital for the implementation of support. The purpose is to increase by 5% to 20% the survival of victims of out-of-hospital refractory cardiac arrests with a good neurological prognosis. Main objective: The hypothesis is that pre-hospital ECMO will result in survival for 20% of the patients, considering that the percentage of survival with in-hospital ECMO is less than 5%. Main judgement criterion: Survival with good neurological outcome (CPC 1 or 2) on discharge from intensive care or at 6 months Secondary judgement criteria: Success rate of the implementation of ECMO ECMO implementation time Immediate complications: haemorrhage, infection Number of organ harvesting The quality of survivors' neurological status according to the CPC neurological classification at D 28, 2 months and 1 year Predictive indicators of the prognosis during cardiac arrest via cerebral and biological monitoring Methodology, type of study: This is a prospective randomised study of current care Sample size (SS, power, risk): A total number of 105 patients in each group will make it possible to demonstrate at the alpha risk of 5% and a power of 1-β=90%, a significant difference in favour of early pre-hospital ECMO compared to the current practice with in-hospital ECMO.
The Cardiovascular disease research using Linked Bespoke studies and Electronic Records (CALIBER) e-health database was the data resource for this study. CALIBER links patient records from four different data sources: Clinical Practice Research Database (CPRD), MINAP (Myocardial Ischaemia National Audit Project registry) Hospital Episodes Statistics (HES), the Office for National Statistics (ONS).
Acute deterioration among hospitalised patient can result in serious adverse events like cardiac arrest, unexpected death or unanticipated intensive care unit (ICU) admission. Most events are preceeded by deteriorating vital signs, and potentially avoidable. To detect and treat hospitalised at-risk patients early an early warning score (EWS) was introduced at the investigator site. EWS measures of a number of physiological parameters that are aggregated to a common score, that directs monitoring frequency, clinical interventions and competency of the provider. Patients with low scores (0 - 1) are monitored every 12th hour and seldom experience serious adverse events. The optimal monitoring frequency for this group is unknown, and presently based on a compromise between patient safety and work load issues. The aim of the present study is to explore if an 8 hourly monitoring interval (intervention) is correlated with a better outcome than 12 hour intervals (control), based on the number of patients that deteriorate to a higher EWS 24 hours after hospital admission in each group.
Connective tissue diseases have been related to heart conduction disorders. The anti-Ro/SSA antibodies are thought to have a pathogenic role, and they most prevalent in systemic lupus erythematous (SLE). The aim of this study is to evaluate the relationship between SLE, arrhythmias and its serologic profile.
