Active clinical trials for "Atrial Fibrillation"

The purposes of this study are to assess the prevalence of patients with a low risk of stroke or systemic embolism based on a CHA2DS2-VASc score among patients who have an AF-related thromboembolism and to identify the clinical and laboratory risk factors associated with thromboembolism in AF patients with a CHA2DS2-VA score of 0 or 1.

The study was to retrospectively analyse the efficacy and safety of LAA closure using the LAmbre in our center from April 2014 to November 2015.

Abiraterone associated with prednisone is used in prostate cancer. Abiraterone is a selective small-molecule inhibiting cytochrome P450 17A1 (CYP17A1), a key enzyme in androgen synthesis. CYP17A inhibition is also responsible for mineral corticosteroid related adverse events as hypokaliemia, fluid retention, and hypertension. Primary hyperaldosteronism is associated with cardiovascular toxicities such as atrial fibrillation and cardiac failure. Other androgen-deprivation therapies are not associated with increased mineral corticosteroid level. This study investigates reports of cardiovascular toxicities for treatment including L02 (sex hormones used in treatment of neoplastic diseases), and G03 (sex hormones) used in prostate cancer in the French pharmacovigilance database and in the EudraCT database.

Background: Different studies with real-life data and randomized controlled trials have shown a detection rate of paroxysmal atrial fibrillation (AF) of 10-20% in patients with cryptogenic stroke using insertable continuous cardiac monitoring for 6 months. More studies are needed, however, to identify factors which can be used to select the patients where the possibility of detecting AF with prolonged rhythm monitoring is highest, to evaluate the best duration of rhythm monitoring, to determine the optimal definition of short-term AF that warrants intervention and to evaluate whether intervention results in improved clinical outcomes. Methods: The NOR-FIB study is a multi-centre prospective observational trial, designed to evaluate detection of AF in cryptogenic stroke and transient ischemic attack (TIA). Patients admitted with cryptogenic stroke or TIA in stroke units in the Nordic countries, aged 18-80 years are included and have the Reveal LINQ® Insertable cardiac monitor system implanted for 12 months for the purpose of AF detection. Biomarkers that may identify patients, who could derive the most clinical benefit from the detection of AF by prolonged monitoring, are being studied. Conclusion: This NOR-FIB study will increase our knowledge regarding the occurrence of AF in patients with cryptogenic stroke and TIA that potentially can improve secondary prevention. The study will provide information on biomarkers that may be used to select cryptogenic TIA and stroke patients for long-term monitoring as well as information on the significance of short-term AF and optimal duration of cardiac rhythm monitoring.

The objective of this project is to evaluate a treatment decision aid for patients with atrial fibrillation.

The purpose of this study is to study the effects of transthoracic electrical cardioversion for restoration of sinus rhythm in patients who present with recent onset atrial fibrillation, with regard to new silent cerebral thrombo-embolic lesions and cognitive function, as well as electrical and functional/structural reverse remodelling, and its effects on inflammatory changes / specific cardiac biomarkers, vasoactive peptides, coagulation activity, and active fibrinolysis.

Atrial Fibrillation (AF) It is the most common arrhythmia in the world. It carries great public health significance because of its prevalence, additional morbidity and mortality. It provides a 4-5 times higher risk of developing a ischemic stroke or transient ischemic attack. In term, this risk can be 70% reduced by taking oral anticoagulants. Actionable AF is the overarching term for silent AF (asymptomatic AF) and undertreated AF (known AF, but not sufficiently protected against ischemic stroke). It is recommended that over the age of 65, patients should be screened with pulse palpation or rhythm strip for the presence of AF. The MyDiagnostick is a single-lead I, compact hand-held device that analyses heart rhythm during one minute. During preoperative consultation, this device will be used to value the yield of screening for actionable AF.

In order to understand the risks and benefits of edoxaban use in a real-world clinical setting in the Non-valvular Atrial Fibrillation (NVAF) indication, Daiichi-Sankyo proposed this post-authorization safety study (PASS) to gain insight into the safety (bleeding, liver adverse events, all-cause mortality and other drug related adverse events) of edoxaban use in patients with NVAF who were not preselected.

Use of new oral anticoagulants (NOAC) in patients before and after catheter based pulmonary vein isolation (PVI) is still controversial. Experience is reported from consecutive patients ablated with PVI for atrial fibrillation and treated with dabigatran, rivaroxaban, or apixaban from Nov 2011 until Dec 2014. Patients are followed for 3 month after ablation. All complications possible being related to the use of NOAC are registered.

The purpose of this registry is to reflect on standard clinical practice in pulmonary vein cryoablation in Spanish hospitals, the different procedure protocols, details of intervention, complications, long-term follow-up strategy and results in these subjects.
