Registration Study of Acute Ischemic Stroke/Transient Ischemic Attack (TIA) With Atrial Fibrillation...
Acute Ischemic StrokeAtrial FibrillationPatient Registration Study of Acute Ischemic Stroke/transient ischemic attack(TIA) With Atrial Fibrillation (AISWAF) is a single-center prospective, consecutively, observational study, was conducted in patients with acute ischemic stroke/TIA with atrial fibrillation. The aim of this study was to understand the stroke mechanism, the regularity of stroke recurrence and its influencing factors, to establish a risk stratification model for stroke recurrence, and to preliminarily explore the relationship between stroke mechanism, risk stratification and antithrombotic regimen in this population.
Atrial Fibrillation Research Database
Anticoagulants and Bleeding DisordersAtrial FibrillationAll patients with atrial fibrillation who are treated with vitamin-k antagonists (warfarin, phenprocoumon) or non vitamin K oral anticoagulants (Dabigatran, Rivaroxaban, Apixaban, Edoxaban) in real world settings will be recorded in this register. Within this register a characterization of patients and therapy (with regard to medication, dose and duration) will be done. On basis of defined clinical relevant end points the long-term efficacy and safety will be evaluated.
RE-ELECT. Dabigatran vs Warfarin in AF Patients With T2DM and CKD
Atrial FibrillationT2DM (Type 2 Diabetes Mellitus)1 moreKidney function in patients with atrial fibrillation (AF) is tending to decline over a time which is clearly demonstrated in clinical studies. Renal impairment is a risk factor for stroke, its progression is associated with unfavorable prognosis. So preserving kidney function should be considered as a one of priorities when choosing treatment strategies which is especially important in patients with existing chronic kidney disease (CKD) or in patients who have risk of its development. This is especially relevant for the patients with type 2 diabetes mellitus (T2DM) and with CKD who can be considered as a group of risk for rapid kidney function decline.
Integrative Management of Patients With Atrial Fibrillation Via Hospital-Community-Family-Based...
TelemedicineAtrial FibrillationAtrial fibrillation (AF) is one of the most common arrhythmias. Its repeated fluctuations in ventricular rate and irregular heart rhythm not only reduce exercise tolerance and quality of life, but also cause hemodynamic changes. The incidence of stroke is increased by 5 times or more compared with the average person. According to statistics, the annual mortality rate from stroke due to atrial fibrillation is about 20%-25%. Of course, like other cardiovascular diseases, atrial fibrillation occurs in a large proportion of the elderly population. According to statistics, 80% of patients with atrial fibrillation are 65 years of age or older. With the aging of the world's population, especially in the 21st century, the proportion of patients with atrial fibrillation has increased year by year. The treatment of atrial fibrillation involves many aspects such as switching to sinus rhythm, controlling heart rate and anticoagulant therapy, which is a long course affecting the adherence of AF patients. AF is a kind of disease that can be preventable and controllable. The out-of-hospital care for AF patients has been proved to reduce the mortality and unexpected readmission rate, but there are still high costs, poor compliance, low management efficiency and etc. Telemedicine was believed to solve these problems to further reduce the mortality of AF patients. The latest ESC Heart Failure Guidelines emphasis the significance of telemedicine in AF, however, it didn't provide a standardized AF remote management system.
Atrial Electromechanical Function in Endurance Athletes With and Without Atrial Fibrillation
Paroxysmal Atrial FibrillationThis study evaluates cardiac structure and function differences between healthy endurance trained athletes with atrial fibrillation and healthy age matched endurance trained athletes without atrial fibrillation. It is hypothesized that despite having similar structural adaptations of the heart (due to endurance training), athletes with atrial fibrillation display will impaired heart functional measures compared to endurance athletes without atrial fibrillation.
Stent Placement and the Risk of New-onset AF in Patients With AMI
Atrial Fibrillation New OnsetAcute Myocardial InfarctionThe benefit of a drug-eluting stent (DES) in patients with acute myocardial infarction (AMI) is controversial. This study will aim to observe the effect of a DES on the risk of new-onset AF in patients with AMI.
Microparticles Circulating Plasma Concentration in Atrial Fibrillation After Percutaneous Occluding...
Atrial FibrillationThe aim of the study is to compare levels of differnts types of microparticles circulating before and after percutaneous occluding of the left atrium by patients with atrial fibrillation and patients control. Hypothesis is that prothesis implantation will decrease levels of microparticles circulating in blood circulation because of occluding of the left atrium .
Influence of an Innovative Telemetric Smartphone Application on Re-hospitalization
Paroxysmal Atrial FibrillationA randomized, open, mono-centric pilot study to investigate the influence of an innovative telemetric smartphone application on re-hospitalization and quality of life after cryoballoon pulmonary vein isolation in patients with paroxysmal atrial fibrillation.
Atrial Fibrillation and Carotid Atherosclerosis in Ischemic Stroke Patients-(AFCAS)
Ischemic StrokeAtrial Fibrillation1 moreThe main aim of the study is to investigate the prevalence and characteristics of ischemic stroke patients with atrial fibrillation and concurrent carotid atherosclerosis. Additionally, this study will investigate the effect of concurrent carotid atherosclerosis on the outcomes of recurrent stroke, myocardial infarction and death during follow-up
Substrate Guided Ablation Therapy for Atrial Fibrillation
Persistent Atrial FibrillationAtrial fibrillation (AF), often referred to as an 'irregular heartbeat', is the most common abnormal heart rhythm worldwide. AF may be intermittent (termed paroxysmal) or sustained (termed persistent).Catheter ablation is increasingly being used to manage individuals with AF, however in a significant proportion of cases AF recurs. Such rhythm control interventions are known to be less effective in individuals with persistent AF compared with those with paroxysmal AF. Analysis of heart tissue of individuals with AF show deposition of scar tissue within the heart muscle and this scar tissue promotes abnormal electrical activity that is involved in causing AF. The aim of the proposed study is to evaluate the feasibility and effectiveness of combining conventional pulmonary vein isolation (PVI) during catheter ablation for AF with adjunctive substrate ablation.
