Filter by:Explorative study in Atrial Fibrillation patients to assess Safety and Pharmacokinetics at initiation of treatment and at steady state
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. The incidence and prevalence of AF increase exponentially with increasing age and AF is associated with higher mortality, more frequent hospitalization, and lower quality of life. Furthermore, AF is often associated with heart failure. The majority of AF is initiated by ectopic foci found primarily in the pulmonary veins. It was shown that catheter ablation of those veins could eliminate episodes of AF. In patients with heart failure, catheter ablation could improve cardiac function, symptoms and quality of life. It remains still unknown whether AF ablation is more effective than conventional treatment in terms of mortality and morbidity.
Prospective study assessing the incidence of atrial high rate episodes (AHRE) in pacemaker patients with and without previously diagnosed AT.
To evaluate the effects of K201 on sinus rhythm restoration, symptom score, various cardiovascular parameters, and safety.
The purpose of this study is to assess the safety and tolerability of AZD0837 in patients with atrial fibrillation who are unable or unwilling to take vitamin K antagonist therapy for up to 3 months.
We are performing a research study to learn more about the control of an individual's blood thinning (anticoagulation) on warfarin. Individuals from an anticoagulation clinic are being asked to participate in order to see if a lottery which provides the opportunity to win money in combination with the use of the Med-eMonitor might be useful in helping patients to achieve better control of their anticoagulation therapy. Half of the participants will be enrolled in the lottery arm and the other half will be a control group who will receive the Med-eMonitor only.
The purpose of this study is to determine the optimal images of the heart structures which are used to guide AF ablation or BiVenticle and coronary vessels.
A form of irregular heart rate called, Atrial Fibrillation (AF) is a major clinical problem. It afflicts about 2 million Americans and is the single largest heart related cause of stroke. However, despite 120 years of speculation and research, the mechanisms that cause AF are poorly understood. Acute AF is also the most common irregular heart rate after open-heart surgery in patients. This is seen in as many as 30% of such patients and often results in a longer hospital stay. In this study we would like to study the pattern of atrial fibrosis (scar tissue in the heart) and an associated blood marker (a protein called pro-collagen-1) in those patients concurrently having open heart surgery.
The purpose of this study is to determine whether pretreatment with atorvastatin protects against atrial fibrillation following off-pump coronary artery bypass graft surgery.
Several case reports indicate that the use of the antibiotic combination amoxicillin and clavulanic acid (AM-CLAVAC) can interact with warfarin pharmacodynamics. However, fever per se might also be responsible of these warfarin overdose reports, as well as the use of high dose paracetamol. The aim of the present study is to determine if AM-CLAVAC can increase the pharmacodynamics of warfarin among patients at steady state Double blinded cross over controlled study vs placebo performed in 12 evaluable patients treated with warfarin with an INR target 2 to 3 and a stable INR and a stable dose.
