Active clinical trials for "Death, Sudden, Cardiac"

Implantable cardioverter-defibrillators have been proven to be effective in the prevention of sudden cardiac death in high-risk patients. However, it is well acknowledged that such a strategy could be optimised, especially through new technologies/devices. Data on the entirely sub-cutaneous implantable cardioverter defibrillator (S-ICD) published so far come from high-volume centers and/or selected populations. The HONEST Cohort -taking the opportunity of a unique scenario with a single manufacturer and remote monitoring system available- aims to collect retrospectively baseline information as well as follow-up of all patients implanted with an S-ICD in France since the first implant in October 13, 2012 until December 31, 2019. An extended prospective yearly follow-up will be carried out since January 1, 2020 until December 31, 2024.

The implantable device therapy for cardiac arrhythmias has been an established therapy, and one of the common standard procedures in cardiac clinical practice. Pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy have been developed since 1960s, and the technologies in this field are still progressively developing. Not only these "traditional" implantable devices, there are multiple new devices for cardiac diseases, such as implantable loop recorder, vagal nerve stimulator and barostimulator. The aim of this registry is to demonstrate the efficacy and the safety of standard device implantation procedures and to evaluate/ identify specific factors, including clinical characteristics, laboratory data and procedural data, which predict the prognosis/complication of the patients. These identification will result in further improvement of patients' care.

This post market clinical follow-up study is a multi-center, non-randomized, unblinded, observational registry of the performance of the FRx Automated external defibrillator (AED) used in conjunction with electrodes with or without use of the infant/child key. The registry is focused only on on post-event data collection and does not prescribe any device usage. This registry has several safeguards in place to prevent against selections bias, including enrollment of all participants who have pads placed. This registry will evaluate the safety and verify the clinical performance of the device in relation to its claims, when used in accordance with the Device Manual.

The objective of this observational study is to assess clinical benefits of innovative features (e.g. Bluetooth technology and smartphone patient applications) in a patient population that is implanted with standard indication for implantable cardiac defibrillator.

S-ICD avoids the use intravascular leads and their associated risks, has been increasingly used for primary and secondary prevention of sudden death. The long-term safety and feasible of S-ICD system in Asian population with a smaller body size remain unclear. The investigators propose to perform a prospective study in Korean population to investigate the safety and feasibility of S-ICD for primary or secondary prevention of sudden cardiac death.

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

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

Background: Bruton s tyrosine kinase inhibitors (BTKi) are used to treat a form of leukemia. But taking BTKi can also increase a person s risk of developing an abnormal heart rhythm. This can cause sudden death. In this natural history study, researchers want to learn how BTKi affects the heart. Objective: To identify and monitor the effects of BTKi on the heart. Eligibility: People aged 18 and older currently receiving or planning to receive BTKi. Design: Participants who have not yet started BTKi will have 2 required clinic visits: 1 before they start taking BTKi, and 1 about 6 months later. Participants who are already taking BTKi will have 1 required visit. Participants will undergo multiple tests: A physical exam, including collection of blood and saliva. A test that measures heart activity via stickers placed on the chest. A test that uses sound waves to capture images of the heart. An exercise stress test that monitors heart activity and blood pressure while the participant works on a treadmill or stationary bike. Sound wave images of the heart may also be taken while the participant exercises. Stress magnetic resonance imaging (MRI) may be done in place of an exercise test. Participants will lie on a table that slides into a tube. They will be given drugs to stress the heart while images are taken. Participants may wear a device to monitor their heart at home. Participants may have repeat visits if they develop heart symptoms or if they need to stop taking BTKi. They will have follow-up phone calls each year for up to 3 years.

Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European Registry for AAOCA (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres.
