Filter by:The DAVID II Clinical Study evaluates the hypothesis that, in patients needing an ICD but without overt indications for pacing, AAI pacing with maximal concomitant drug therapy will not increase the rate of the combined endpoint of mortality or hospitalization for new or worsened heart failure as compared to patients with ventricular backup pacing.
This study tests the hypothesis that allopurinol, a xanthine oxidase inhibitor, improves heart metabolism in patients with heart failure.
The objective of this study is to evaluate the prevalence of sustained ventricular and supraventricular rhythm disorders in patients implanted with a CONTAK RENEWAL TR2 ventricular resynchronization therapy (CRT) device
The MADIT-CRT trial is designed to determine if combined implantable cardiac defibrillator (ICD)-cardiac resynchronization therapy (CRT-D) will reduce the risk of mortality and heart failure (HF) events by approximately 25%, in subjects who are in New York Heart Association (NYHA) functional Class II with non-ischemic or ischemic cardiomyopathy and subjects who are in NYHA functional Class I with ischemic cardiomyopathy, left ventricular dysfunction (ejection fraction [EF] < or = 0.30), and prolonged intraventricular conduction (QRS duration > or = 130 ms).
The purpose of this study is to determine whether combined mortality and hospitalization in heart failure patients receiving optimal pharmacologic therapy can be reduced by combining optimal pharmacologic therapy and 1) biventricular pacing therapy alone or 2) biventricular pacing with defibrillation.
Discharge to the community is increasingly becoming a priority for patients implanted with a Ventricular Assist Device (VAD). Because VADs are complex, patients and caregivers often fear leaving the hospital, although their status does not require hospitalization. This project includes development of CD/video and web-based instructional programs on management of the VAD controller for patients and their caregivers (formal and informal). A clinical trial will be used to examine discharge rates and placements following patients educated under usual care vs. self-pace CD/video conditions.
Patients hospitalized for treatment of decompensated heart failure (CHF) are at risk for prolonged length of stay (LOS) and frequent readmissions. Renal dysfunction and diuretic resistance contribute to this risk, particularly if renal dysfunction worsens during CHF treatment. Brain natriuretic peptide (BNP) is a hormone of myocardial cell origin with well-defined physiological effects which include arterial and venous vasodilation, suppression of adverse neurohumoral systems and favorable effects on renal hemodynamics and sodium excretion. Recombinant human BNP (Natrecor) is approved by the FDA for treatment of decompensated CHF as it has been demonstrated to lower filling pressures and improve symptoms. While clinical trials and the FDA support the use of BNP as adjuvant therapy in decompensated CHF, the extent of its efficacy in improving non-hemodynamic CHF parameters has not been fully defined. The objective of this clinical practice protocol is to determine whether use of BNP in addition to standard therapy, will preserve renal function and facilitate diuresis in patients with CHF and mild-moderate renal impairment (creatinine clearance > 20 but < 60 ml/min) as compared to standard therapy alone. Patients admitted to the Mayo Heart Failure Service who meet entrance criteria will be randomized to standard clinical practice with or without a 48 hour infusion of BNP. The primary endpoints will be indices of renal function and diuretic response at 1, 2 and 3 days and at discharge. Secondary endpoints will be neurohumoral function, LOS and 30-day readmission rate.
The study is a randomized, placebo controlled, multi-center, single dose study to evaluate cardiac hemodynamics and safety of iv SLV320 in 110 subjects with congestive heart failure requiring diuretic treatment. Each subject will receive one dose of SLV320 or placebo or furosemide. The study consists of three visits (or study days when in-subjects are included). Ambulatory subjects will be in hospital for two nights and one day.
The purpose of this clinical investigation is to demonstrate the safety and effectiveness of the CONTAK® RENEWAL™ 2/4/4HE cardiac resynchronization therapy defibrillator (CRT-D) family and EASYTRAK® 2 lead in delivering LV-CRT or BiV-CRT with an LV Offset for patients with heart failure and an indication for an ICD.
The purpose of this clinical investigation was to assess the safety and effectiveness of the EASYTRAK 3 lead
