Filter by:Old age, less body weight and deteriorated renal function are significant clinical factors for the outcomes of atrial fibrillation- so called 'fragile'- and these are common risk factors in osteoporosis and fracture. Therefore, in real world, these risk factors and co-morbidities are commonly considered when it comes to prescribe anticoagulant in atrial fibrillation patients. Recent study even reported that comorbid atrial fibrillation in patients with osteoporosis might be associated with an increased risk of bone fracture and death after fracture. Because there have been very few data about the effectiveness/safety of anticoagulant among non-valvular atrial fibrillation with prior osteoporosis/fracture, this study is planned to provide real-world evidences for this specific type of non-valvular atrial fibrillation patients.
The study is a prospective, multi-center, non-randomized, unblinded worldwide pre-market clinical study. The purpose of the study is to provide data demonstrating the safety and effectiveness of the PulseSelect™ PFA System for the treatment of atrial fibrillation (AF). The study will also provide first in human insights into clinical safety and device function of the PulseSelect PFA System for pulmonary vein isolation (PVI) as a treatment for AF. To this end, the clinical study has been designed into phases (Pilot and Pivotal), with each phase comprising a separate data set that will be analyzed and reported on per the below objectives.
The aim of the submodule study is to assess whether a high BMI may influence the sensing performance and the sECG quality of the BIOMONITOR.
Among patients who are receiving long-term anticoagulant therapy, whether with a direct oral anticoagulant (DOAC) or vitamin K antagonist (VKA), approximately 3-5% who require treatment interruption for a surgery will do so in an urgent/emergency surgery setting. Additionally, there is considerable morbidity and mortality associated with DOAC/VKA management in an urgent/emergency surgery setting. Thus, this prospective registry study aims to identify and compare determinants for perioperative adverse events in DOAC-treated and VKA-treated patients who require an urgent/emergency surgery, and to identify which of these are modifiable. It also aims to describe and compare management of anticoagulant reversal (i.e., non-specific and specific reversal agents) and resource utilization (i.e., blood transfusion) in DOAC- and VKA-treated patients who need an urgent/emergency surgery.
A prospective, single center, open-label, single arm, study to evaluate the safety and technical performance of the CLAAS system for closure of the left atrial appendage.
There are a wide range of significant epidemiological, clinical, and operative predictors for the development of post-CABG AF including older age, female gender, large LA diameter, higher CHA2DS2-VASc score, valve replacement and postoperative inotropic support. Nevertheless, further large-scale studies are still needed to confirm our findings
The proposed PAUSE-2 RCT study is the logical next step to the Perioperative Anticoagulant Use for Surgery Evaluation (PAUSE) study, which was completed on August 31, 2018. Both studies address the perioperative management of patients with atrial fibrillation (AF) who are receiving a direct oral anticoagulant (DOAC) and require an elective surgery/procedure. PAUSE did not address safe management of patients having a high-bleed-risk surgery/neuraxial anesthesia in whom there is concern about bleeding, especially neuraxial-related epidural hematomas that can lead to paralysis; such patients are often managed by the approach recommended by the American Society of Regional Anesthesia (ASRA). In PAUSE-2, investigators will test the hypothesis: (i) for patients having a high-bleed-risk surgery/neuraxial anesthesia, the simpler "PAUSE management" is as safe (non-inferior) to the more complex "ASRA management". PAUSE-2 will establish a standard for perioperative DOAC management in patients having high-bleed-risk surgery or neuraxial anesthesia. To start, this will be a pilot study of a larger PAUSE-2-RCT. The investigators will be conducting this pilot study to assess the feasibility of the study at this smaller scale.
The incidence of atrial fibrillation (AF), the most common heart rhythm disorder, is increasing. The symptoms of AF include: unpleasant heartbeats; difficulty breathing; tiredness; dizziness; and, reduced exercise capacity. Patients with AF have lower quality of life, higher mental distress, and higher risk of heart disease and stroke when compared to the general population. Further, patients with non-permanent AF tend to experience more severe symptoms and substantial reductions in quality of life when compared to patients with permanent AF. Type 2 diabetes increases the risk of developing AF and accounts for about 20% of patients with non-permanent AF. High blood glucose concentrations and increased blood glucose fluctuations (large and frequent upward and downward blood glucose swings) are commonly seen in type 2 diabetes. Increased blood glucose fluctuations may worsen AF symptoms and quality of life in patients with AF. Exercise improves quality of life and mental health and reduces risk of developing heart disease and stroke. However, no clinical guidelines for managing AF include exercise. High-intensity interval training (HIIT), a form of exercise that alternates between intense bouts of exercise and less intense recovery periods, is a time-efficient approach to improve blood glucose fluctuations in type 2 diabetes. In healthy individuals and in patients with coronary artery disease, HIIT also improves quality of life and mental health. Currently, the effect of HIIT on blood glucose fluctuations, AF symptom severity and quality of life in patients with AF living with type 2 diabetes is unknown. Also, the links between blood glucose fluctuations and AF symptom severity and quality of life have not been investigated.
This clinical trial is designed to compare two management strategies for the treatment of asymptomatic/subclinical atrial fibrillation after ablation based on data from the Biotronik ICM (BioMonitor3® or future generation of Biotronik ICM).
A randomized, open-blinded, prospective study to evaluate the timeliness and safety of direct current cardioversion (DCCV) when using methohexital when compared to the more often used propofol.
