Active clinical trials for "Atrial Fibrillation"

Edoxaban, has shown in clinical registration trials a significant reduction of major bleeding compared to warfarin, especially in elderly patients. Efficacy and safety of edoxaban will be assessed in a cohort of very elderly patients (≥80 years of age) with NVAF. A secondary analysis will correlate outcomes with frailty defined according to SHARE-FI (not-frail, pre-frail or frail).

This is a comparative effectiveness and safety study of clinical events among patients taking either dabigatran or warfarin. There is no formal hypothesis to be tested, but rather to provide the estimates on the incidence of stroke and systemic embolism (effectiveness) and bleeding events (safety) using 95% confidence interval for comparison between those non0-valvular atrial fibrillation patients taking dabigatran vs. warfarin using a large, nation-wide claims data in Japan.

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.

The study objective is to confirm appropriate use and safety profile of Prazaxa® Capsules in real-world setting after the availability of idarucizumab

Despite relatively lower prevalence of atrial fibrillation (AF) in Asians (~1%) than Caucasians (~2%) as reported in observational studies, Asia has a much higher overall disease burden, due to its proportionally larger aged population. Based on reported prevalence rates and projected population figures in Asia, there will be an estimated 49 million men and 23 million women with AF, by year 2050. Stroke is a disabling complication of AF that is of particular cause for concern in Asians patients. Implementing consensus expert recommendations for managing stroke risk in AF patients can considerably reduce stroke rates. However, caution is necessary when aligning management of Asian AF patients to that of their Caucasian counterparts. Current international guidelines and risk stratification tools for AF management are based on findings in predominantly Caucasian populations and may therefore have limited relevance, in certain respects, to Asian patients. The vitamin K antagonist (VKA), warfarin and alternative new oral anticoagulants, direct thrombin inhibitors or factor Xa inhibitors is recommended for reducing the risk of stroke and thromboembolism in high-risk patients with non-valvular AF. However, there is very limited information about the safety and efficacy of those agents in Asian population. Therefore, further research is urgently needed to inform specific guidance on the implications of different stroke and bleeding profiles in Asians versus Caucasians. In order to allow comparison between Asians versus Caucasians population, we propose to adopt the current study protocol and case report form of the EurObservational Research Programme on Atrial Fibrillation General Long-Term study.

The study aims to evaluate the safety and effectiveness comparisons between warfarin, dabigatran, and rivaroxaban in routine clinical practice among Japanese non-valvular atrial fibrillation (NVAF) patients with concomitant coronary artery disease (CAD).

RR2 is a medical, home-care, digital therapeutic, wearable device. Its main purpose is to deliver prescheduled, non-invasive, peripheral neuromodulation therapy, in conjunction with standard medical care, to relieve AF symptoms, recurrence and overall burden.

Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.

To assess if deviating the esophagus will reduce/eliminate ablation injury to the esophagus.

Heart failure (HF) is a syndrome, resulting from structural or functional impairment of ventricular filling or ejection of blood. Effective HF management depends on accurate and rapid diagnosis requiring assessment of symptoms and physical signs in combination with advanced and expensive imaging tools. However, several challenges arise from the traditional symptom-based diagnosis because co-morbidities of HF have similar presentations. This implies the need for a deeper knowledge of mechanistic links among genetic and epigenetic events governing the pathophysiology of HF leading to a novel molecular-based system to differentiate HF phenotypes. Now, it is emerging that the pathophysiology of HFpEF and HFrEF is different, it provides an opportunity to identify biomarker candidates that could aid in HF diagnosis and stratification between these two forms of the disease. The aim of PRESMET project is to perform liquid biopsy strategies to identify novel putative non-invasive epigenetic-sensitive biomarkers that could be used either alone or in combination with established diagnostic tests, such as natriuretic peptide, to help differentiate HFpEF from HFrEF. The Investigators will perform DNA methylation analysis on CD4+ T cells isolated from patients versus controls. Remarkably, big data generated from NGS tools will be analyzed by advanced network-oriented algorithms. Our results may provide a useful clinical roadmap in order to improve precision medicine and personalized therapy of HF.
