Prospective Study on Primary Aldosteronism in Resistant Hypertension
Prevalence of primary aldosteronism (PA) in resistant hypertension is not clear. In addition, emerging evidence supports the role of elevated serum aldosterone in promoting cardiovascular disease, independently from high blood pressure (BP) levels, but current data on this issue are heterogeneous.
Echocardiographic Predictors of Atrial Fibrillation
This prospective study aims to identify the diagnostic accuracy of echocardiographic predictors of atrial fibrillation in patients with ESUS (embolic stroke of undetermined source) or TIA (transient ischemic attack).
Ultra-High Frequency - Electrocardiogram (UHF-ECG) for the Diagnosis of Ventricular Electrical Dyssynchrony (VED)
The purpose of this study is to demonstrate the safety and effectiveness of the VDI UHF-ECG System in the diagnosis of ventricular dyssynchrony when compared to the 12-lead ECG in patients with bradycardia and heart failure indicated for pacemaker implantation.
Data Collection for Echocardiography-Based Software Assessment
This is a prospective, observational study collecting data from routine clinical care. The information gathered will be used to support the evaluation of a software-based tool. No investigational procedures or treatments are introduced, and all data are obtained as part of standard-of-care activities.
Impact of Catheter Ablation on ABC Risk Scores
The aim of this prospective, monocentric, non-randomized trial is to investigate the impact of catheter ablation of atrial tachyarrhythmias on the ABC-stroke and ABC-bleeding risk scores. Participants planned for first catheter ablation for symptomatic atrial tachyarrrhythmias (atrial fibrillation, atrial flutter) will be enrolled. Serial blood samples will be collected before …
Stroke Risk Assessment and Markers of Blood Clotting in Patients With Newly Diagnosed Non-valvular Atrial Fibrillation (NVAF), Who Have Not Received Oral Anticoagulation Therapy (OAC-therapy) Prior to Inclusion
Background Atrial fibrillation (AF) is the most common heart rhythm disorder worldwide. Globally, there are 37.5 million people with AF. AF increases the risk of death, heart failure, and stroke, which severely affect patients and also lead to high healthcare costs. Around 25% of all strokes are caused by AF, …
Clinical Study on the Effect of CPAP on AF Recurrence After Catheter Ablation in Patients with AF and OSA
Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice, significantly increasing the risks of death, stroke, heart failure, cognitive impairment, and dementia, thus severely impacting patients' quality of life. However, for AF patients with concomitant cardiovascular risk factors, particularly those with obstructive sleep apnea (OSA), the success …
Fetal Electrophysiologic Abnormalities in High-Risk Pregnancies Associated With Fetal Demise
Each year world-wide, 2.5 million fetuses die unexpectedly in the last half of pregnancy, 25,000 in the United States, making fetal demise ten-times more common than Sudden Infant Death Syndrome. This study will apply a novel type of non-invasive monitoring, called fetal magnetocardiography (fMCG) used thus far to successfully evaluate …
DOAC in Chinese Patients With Atrial Fibrillation
Direct oral anticoagulants (DOACs) have emerged as safe and efficacious ischemic stroke prophylaxis for non-valvular atrial fibrillation (NVAF). All four DOACs - apixaban, dabigatran, edoxaban, and rivaroxaban - were shown to reduce the risk of major bleeding compared to warfarin. The predictable pharmacokinetic profiles of DOACs also favour their use …
Mechanisms for Atrial Fibrillation in Obstructive Sleep Apnea
Atrial fibrillation (AF) is the most common rhythm disorder and involves an increased risk of cardiovascular disease and death, impaired quality of life and a high proportion of healthcare consumption. An important risk factor is obstructive sleep apnea (OSA). However, it is not fully understood why OSA induces AF. It …
