Filter by:The purpose of this study is to assess whether repeated enhanced and prolonged ECG monitoring after ischemic stroke results in a higher detection of atrial fibrillation (/flutter) compared to usual care (at least 24 hour of cardiac monitoring).
Catheter ablation has emerged as an effective therapy for atrial fibrillation (AF). However, achievement of complete& durable isolation of the pulmonary veins (PVs) is challenging, primary limited both by operator experience and also the limits of currently available ablation technology. Direct contact force sensing (CFS) is a novel technology that may help to ensure adequate lesion delivery. CFS may also help to improve the safety profile of catheter ablation. The purpose of this study is to compare two strategies of wide antral PV isolation plus linear ablation for persistent AF: 1. guided by contact force sensing (CFS) OR 2. blinded to contact force sensing (CFS) - i.e. standard approach
This study plans to describe utilization patterns for oral anticoagulants over time in patients with non-valvular atrial fibrillation at risk for stroke using electronic claims data from a United States commercial insurance database.
This cohort study plans to identify initiators of oral anticoagulants using electronic claims data from a commercial insurance database to quantify associations between anticoagulant choice (warfarin and dabigatran) and the occurrence of selected outcomes in patients with non-valvular atrial fibrillation at risk for stroke.
According to data from high volume Centres, documentation of entry block with the Achieve catheter may be possible in only about to 50% of pulmonary veins. The investigators aim to assess strategies using the Achieve catheter that can improve this performance.
The aim of this prospective randomized double-blind study was to compare the efficacy and safety of Botulinum toxin injection in epicardial fat pads for preventing recurrences (in early postoperative period) of atrial tachyarrhythmia in patients with paroxysmal atrial fibrillation undergoing coronary artery bypass graft (CABG) surgery.
The aim of the present study is to investigate the possible effects of supplementation with 1.8 g/day of n-3 polyunsaturated fatty acids on cardiovascular morbidity and mortality during a follow-up period of 2 years in an elderly population after having experienced an acute myocardial infarction. The hypothesis is that this supplementation on top of modern therapy will reduce the combined cardiovascular end-point of death, non-fatal myocardial infarction, stroke, revascularizations or hospitalization for new or worsened heart failure with at least 30%.
A study for subjects with atrial fibrillation (AF) or atrial flutter who are diagnosed with left atrial (LA) or left atrial appendage (LAA) thrombus. The study will assign subjects to rivaroxaban for treatment of thrombi. The study will measure thrombus outcomes based on echo image and common clinical outcomes such as bleeding and stroke or thromboembolism.
The purpose of this study is to assess the efficacy of F373280 on the maintenance of normal cardiac rhythm after direct electric cardioversion in patients with persistent atrial fibrillation and cardiac failure.
The primary purpose of this study is to evaluate the safety for 2 different rivaroxaban treatment strategies and one Vitamin K Antagonist (VKA) treatment strategy utilizing various combinations of dual antiplatelet therapy (DAPT) or low-dose aspirin (ASA) or clopidogrel (or prasugrel or ticagrelor).
