Filter by:The purpose of this study is to test the hypothesis that dietary supplementation with an algal source of docosahexaenoic acid (DHA) can improve the heart rate variability in elderly patients.
The overall hypothesis of this study is that subtle interactions between structural (substrate) and functional (trigger) abnormalities of the heart, some of which are genetically-determined, can be used to identify patients at high risk of sudden cardiac death (SCD). Such information may be used to better define patients most likely to benefit from replacement of an internal defibrillator (ICD). The prospective, observational study to enroll, categorize and follow patients who receive an ICD pulse generator replacement for primary prevention of SCD (PROSe-ICD) was established to : 1. to gain a better understanding of the biological mechanisms that predispose to SCD 2. to develop readily determined clinical, electrocardiographic, genetic and blood protein markers identify patients with an increased risk of dying suddenly
This trial evaluates the safety and effectiveness of catheter ablation for PAF. The investigational catheter being studied is the NAVISTAR® THERMOCOOL® irrigated-tip catheter. At the time of this study, the NAVISTAR® THERMOCOOL® Catheter was FDA-approved for commercial distribution in the U.S. for treating patients with Type I atrial flutter and drug refractory monomorphic sustained ventricular tachycardia post myocardial infarction. The catheter was approved for use in Europe for endocardial ablation for treating cardiac arrhythmias.
The aim of the study is to examine the effects of fatty fish and white (lean) fish on cardiovascular disease risk factor levels in subjects with established coronary heart disease using multiple medications. The main end points are blood pressure, serum lipids, inflammatory markers, arrhythmias and gene expression in peripheral mononuclear cells. The study design was a controlled, parallel study lasting 8 weeks with three diet groups: fatty fish, white fish and control group (lean pork, beef or chicken).
The purpose of the study is to evaluate the safety and performance of the Sleuth Monitoring system.
Prospective study assessing the incidence of atrial high rate episodes (AHRE) in pacemaker patients with and without previously diagnosed AT.
The purpose of this study is to assess the effectiveness of a 10 week program of Stress Management versus control Patient Education sessions on cardiac responses to mental stress in veterans with Implantable Cardioverter-Defibrillators
Adult myotonic muscular dystrophy (Steinert's disease) is the most common inherited neuromuscular disorder. Cardiac rhythm disturbances occur frequently in this disease state and may be responsible for up to one-third of deaths. In this study, we intend to evaluate the utility of non-invasive electrocardiographic screening methods and history in predicting serious arrhythmic events.
The purpose of this study is to assess the long-term effects of catheter ablation procedures performed at the OU Medical Center.
To investigate whether statin therapy utilizing the drug Lipitor (atorvastatin) might be effective in preventing short-and long-term atrial fibrillation (AF) following a left atrial ablation procedure. We further hypothesize this reduction will result from diminished peri-procedural inflammation, which will be reflected in lower C-Reactive Protein (CRP) values in the blood.
