Filter by:The Medtronic CapSure Epi Lead Post-approval Study will assess long-term safety of the 4968 lead. This study is part of the Medtronic System Longevity Study.
Safety and effectiveness will be summarized for the model 4965 lead. This study was conducted within Medtronic's System Longevity Study (SLS).
The purpose of this study is to determine whether waveforms of the intracardiac electrograms, acquired through an ICD, can be used: - to predict malignant ventricular arrhythmias, requiring appropriate ICD therapies, and - to predict progression of heart failure in patients with ICD.
The (Catheter Ablation Versus Anti-arrhythmic Drug Therapy for Atrial Fibrillation Trial) CABANA Trial has the overall goal of establishing the appropriate roles for medical and ablative intervention for atrial fibrillation (AF). The CABANA Trial is designed to test the hypothesis that the treatment strategy of left atrial catheter ablation for the purpose of eliminating atrial fibrillation (AF) will be superior to current state-of-the-art therapy with either rate control or rhythm control drugs for decreasing the incidence of the composite endpoint of total mortality, disabling stroke, serious bleeding, or cardiac arrest in patients with untreated or incompletely treated AF.
Depression in cardiac patients is common, persistent, and deadly. However, the vast majority of cardiac patients with depression go unrecognized and untreated, despite the existence of treatments that clearly improve depressive symptoms and may favorably impact survival. Our research group and others have found that depression recognition and treatment appears particularly limited among patients with acute cardiac illness, though this population may be the most vulnerable to the deleterious effects of depression. We propose a project, building on successful collaborative care depression management programs in outpatient settings, to address this important issue. The specific hypotheses behind the proposed research are that a collaborative care depression management program can be successfully adapted to inpatient cardiac units, and that such a program will lead to greater rates of adequate depression treatment and improvements in secondary outcomes. The following specific aims capture the stepwise goals of this program: 1. To determine whether a collaborative care depression management program ('Enhanced Care') leads to significantly increased rates of adequate depression treatment compared to usual care (screening and feedback) (Primary Aim). 2. To assess whether this Enhanced Care program has a lasting impact on adequate depression treatment, depressive symptoms, health-related quality of life, and adherence to medical recommendations at 6 weeks, 12 weeks, and 6 months, compared to usual care.
An implantable cardioverter defibrillator (ICD) administers a shock to terminate potentially life-threatening cardiac arrhythmias. The device saves lives, but presents psychological challenges for patients. At present, there is a paucity of brief interventions for ICD patients designed for administration in a clinic setting that considers issues of cost, time, and available resources. The present study examined the impact of a brief cognitive behavioral (CBT) educational intervention on primary endpoints of patient acceptance and quality of life and secondary endpoints of depression and anxiety. It was hypothesized that the intervention would result in significant improvements primary and secondary endpoints for participants in the intervention group.
The purpose of this study is to determine if atorvastatin (Lipitor) reduces the occurence of abnormal heart rhythm (atrial arrhythmia) following non cardiac thoracic surgery.
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 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).
