Intravenous Tedisamil in the Rapid Conversion of Atrial Fibrillation or Flutter to Normal Sinus...
Atrial FibrillationAtrial FlutterThe purpose of this study is to demonstrate the ability of tedisamil to convert atrial fibrillation or flutter into normal sinus rhythm (NSR) in female patients.
Trigger- vs. Substrate-Ablation for Paroxysmal Atrial Fibrillation
Atrial FibrillationThe purpose of this study is to compare two strategies of catheter-based treatment of paroxysmal atrial fibrillation: Pulmonary vein isolation either alone or combined with electrogram-guided substrate-ablation.
Clinical Performance of AFGen1
Atrial FibrillationAfib1 moreAFGen1 is indicated for use on symptomatic or asymptomatic adults who are at risk of developing or who have atrial fibrillation, where a software assisted analysis of ambulatory ECG is needed to identify episodes of Afib. The purpose of this study is to establish the clinical performance of AFGen1 on human participants.
Electrical Coupling Information From The RHYTHMIA HDx Mapping System and DIRECTSENSE Technology...
Paroxysmal Atrial FibrillationThe objective of this study is to evaluate whether local impedance (DIRECTSENSE™) drop on the INTELLANAV STABLEPOINT™ ablation catheter is associated with late pulmonary vein (PV) reconnections and durable conduction block in patients undergoing de novo PV isolation (PVI) for treatment of paroxysmal atrial fibrillation (PAF).
Relationship Between the Posterior Atrial Wall and the Esophagus: Esophageal Position and Temperature...
Atrial ArrhythmiaA multimodal strategy integrating esophageal visualization with the multidetector computed tomography (MDCT) and simultaneous temperature monitoring has never been put into practice. We have developed an isodistance map (esophageal print) to depict the atrio-esophageal relationship and to analyze the esophageal position peri procedurally. The present randomized study intends to analyze the usefulness of the esophageal print in predicting local thermal heating of the esophagus.
Clinical Decision Support for Atrial Fibrillation and Flutter
Atrial Fibrillation and FlutterAtrial fibrillation (AF) is a major public health problem: it impairs quality of life and independently heightens the risks of ischemic stroke, heart failure and all-cause mortality. AF is a common reason for presenting to emergency departments (ED) in Kaiser Permanente Northern California (KPNC) and is associated with frequent hospitalization. Additionally, inter-facility hospitalization rates for AF vary across KPNC. Improvements in modifiable components of ED AF care could potentially reduce low-yield hospitalizations and the associated costs, patient inconveniences, and complications that can ensue. Real-time clinical decision support systems (CDSS) can transform entrenched physician practices and improve patient outcomes. The investigators will conduct a stepped-wedge cluster randomized trial of a CDSS intervention across 13 KPNC EDs for the comprehensive management of acute AF with the following three aims: 1) To evaluate the impact of the CDSS intervention on index hospitalization rates; 2) To evaluate the impact of the CDSS intervention on ED AF rate and rhythm control process-of-care metrics; and 3) To evaluate the impact of the CDSS intervention on AF stroke prevention actions for eligible participants at the time of ED discharge. The investigators hypothesize that the CDSS intervention will safely reduce index hospitalization rates, improve rate and rhythm control process-of-care metrics, and increase stroke prevention actions for eligible participants at ED discharge and within 30 days.
PRevalence of Obstructive Sleep apnoEa and Reduction of Promoters in AF
Atrial FibrillationOsa SyndromeThis study aims to identify how many patients who have atrial fibrillation, also have sleep apnoea. This is important because sleep apnoea can be a trigger to atrial fibrillation and it can be corrected with a simple intervention. Therefore it is important to understand its prevalence (how many patients with atrial fibrillation are affected by it). Also, obesity and sleep disorders are often associated, therefore the evolution of atrial fibrillation is studied in patients who also have obesity and have lost weight compared with patients who did not loose any weight or are not obese. As medications or therapy are not changed, this is an observational study.
Singapore Cardiac Longitudinal Outcomes Database
Coronary Artery DiseaseCongestive Heart Failure1 moreThe research project aims to perform data extraction, integration and analysis across multiple clinical, administrative, financial and pharmacy databases in the participating institutions. The key data components will include clinical cardiovascular specific data, procedural data, financial and administrative data (e.g. cost of medications and supplies, length of stay, diagnosis codes etc.), short-to-long term clinical outcomes (including hospital re-admissions, cardiovascular events, death), and quality-of-care indices (e.g. compliance to guideline-recommended therapy and medications). The research project will involve all patients proven and/or suspected with coronary artery disease (CAD), congestive heart failure (CHF) and atrial fibrillation (AF) admitted to National Heart Centre Singapore (NHCS) and NUH.
Supporting Use of AC Through Provider Profiling of Oral AC Therapy for AF
Atrial FibrillationPrescribing Practices1 moreThe SUPPORT-AF study aims to improve rates of anticoagulation (AC) in atrial fibrillation (AF) patients by developing and delivering supportive tools and educational materials to providers treating patients with AF. The investigators hypothesize that AC percentage will increase among providers receiving tools and educational content.
Improved Cardiovascular Risk Reduction to Enhance Rural Primary Care
Diabetes MellitusHypertension3 moreThe trial will examine whether a centralized Prevention Health & Cardiovascular Risk Service (PHCVRS) run by clinical pharmacists at the University of Iowa can be implemented in primary care offices and whether it can improve the care delivered to patients at risk for developing cardiovascular disease.
