NCT ID: NCT03279861 Withdrawn - Hypertension Clinical Trials

Sacubitril-valsartan Versus Usual Anti-hypertensives in LVAD

Start date: November 2017
Phase: Phase 4
Study type: Interventional

This pilot, feasibility study evaluates the efficacy of sacubitril-valsartan (Entresto) versus usual anti-hypertensive medications in patients with left ventricular assist devices (LVAD). It also measures diurnal blood pressure variations in the context of continuous flow physiology.

NCT ID: NCT03227393 Withdrawn - Clinical trials for Heart Failure, Systolic

The Effect of Yoga on Cardiac Sympathetic Innervation Evaluated by I-123 mIBG

Start date: September 30, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate if yoga practice will reduce cardiac sympathetic activity and subsequently cardiac arrhythmias.

NCT ID: NCT03160625 Withdrawn - Clinical trials for Heart Failure With Preserved Ejection Fraction

Evaluation of Rate Adaptive Pacing on Chronotropic Response in Preserved Ejection Fraction HF

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

RESPOND-HF is a prospective, multi-center, non-significant risk pilot study with cross-over design. The purpose of the study is to investigate if rate adaptive pacing has the potential to provide benefit to HF patients with preserved ejection fraction, referred to as HFpEF patients. Findings from this pilot study may be used to guide subsequent efforts to design and conduct a prospective, randomized, multi-center pivotal trial powered to show improvement in patient outcomes.

NCT ID: NCT03091998 Withdrawn - Heart Failure Clinical Trials

Subcu Administration of CD-NP in Heart Failure Patients With Left Ventricular Assist Device Support

Start date: September 30, 2017
Phase: Phase 1
Study type: Interventional

The worldwide use of left ventricular assist devices (LVAD), which is mechanical device to improve hemodynamic function, has improved the outcomes of severe heart failure (HF) patients leading to the continued annual increase in the number of LVAD implantations. However LVAD support still results in major complications such as renal failure or gastrointestinal bleeding. The investigators hypothesize that such major complications may be due to endothelial dysfunction induced by the lack of pulsatility, which may be improved by an innovative designer natriuretic peptide, CD-NP. They have demonstrated its favorable actions in animal models as well as humans, and tested its safety in LVAD patients. They hypothesize that CD-NP will have renal and endothelial protective actions through its receptor GC-A and GC-B. Thus, the investigators will test their hypothesis with a highly translational approach to examine CD-NP's role in endothelial and renal protection. The aim is to determine safety and tolerability together with cGMP activating, neurohumoral modulating and renovascular protective properties of chronic subcutaneous delivery of CD-NP compared to placebo in stable LVAD patients for 3 days.

NCT ID: NCT03042130 Withdrawn - Heart Failure Clinical Trials

Treatment With IV Iron in Hospitalized Patients With Severe Heart Failure But Without Iron Deficiency

Start date: December 14, 2016
Phase: Phase 4
Study type: Interventional

Patients with congestive heart failure, grade 3-4, in addition to the standard care, will be randomized 1:1. The study group will receive 2 doses of IV iron (Iron carboxymaltose). The control group will receive standard of care alone. The study will test for the effects of the additional IV iron on the symptoms, clinical picture and quality of life of the treated patients.

NCT ID: NCT03032211 Withdrawn - Heart Failure Clinical Trials

Optimal Balance Alfapump® System Feasibility Study

Start date: December 31, 2017
Phase: Phase 1
Study type: Interventional

1. Summary of Clinical Investigation A summary of the clinical investigation is provided below and includes the primary objective of the study, the safety and feasibility endpoints, the number of subjects to be enrolled, the study duration, the subject follow-up and the inclusion/exclusion criteria. 1. Primary Objective The primary objective of the study is to evaluate the safety and feasibility of the alfapump® System indication for use in the management of fluid in NYHA Class III and ambulatory NYHA Class IV heart failure patients who have an eGFR of > 15 to < 60 mL/min/1.73m2. 2. Study Endpoints 1. Primary Safety Endpoint The primary safety endpoint will be an assessment of the occurrence of adverse events (AEs) and serious adverse events (SAEs) related to: 1. Surgical implant of the alfapump® 2. Device malfunctions 3. Dialysate infusion 2. Secondary Safety Endpoints The secondary endpoint will be an assessment of: 1. Time to first hospitalization related to fluid management after the activation of the alfapump® System and initiation of dialysate infusion has occurred 2. Rate of occurrence of re-hospitalizations related to fluid management 3. All-cause mortality 3. Assessment of Feasibility for Fluid Management in Heart Failure Indication The feasibility of the alfapump® System for management of fluid in NYHA Class III and ambulatory NYHA Class IV heart failure patients with renal dysfunction will be assessed by the net fluid balance as measured by the ability of the alfapump® System to move more fluid to the bladder than dialysate instilled.

NCT ID: NCT03032081 Withdrawn - Heart Failure Clinical Trials

High Intensity Interval Training in Heart Failure

Start date: March 2, 2017
Phase: N/A
Study type: Interventional

The investigators will assess the efficacy and safety of utilizing high-intensity interval training in stable heart failure patients on functional outcomes. Specifically, an assessment of baseline peak oxygen uptake and peak cardiac output will be assessed before and 8 weeks after intense interval training. Measurements of quality of life will be assessed before and after training as well as the number of arrhythmic events before and after training. The control group will be a group that will follow a moderate exercise training protocol over a similar period.

NCT ID: NCT03021213 Withdrawn - Heart Failure Clinical Trials

Treating Heart Failure With Enhanced External Counterpulsation (EECP)

Start date: January 2017
Study type: Observational

Enhanced external counterpulsation (EECP) is an outpatient coronary artery disease (CAD) therapy that involves the cyclical inflation/deflation of cuffs wrapped around the lower extremities. However, the possible benefits of EECP in patients with heart failure (HF) (New York Heart Association [NYHA] classes II to IV) and cardiomyopathy are unclear.

NCT ID: NCT03005184 Withdrawn - Clinical trials for Heart Failure NYHA Class III

Mechanism(s) Underlying Cardiovascular Effects of ARB/NEP Inhibition - Aim 2

Start date: September 2017
Phase: Phase 2
Study type: Interventional

This study tests the hypothesis that endogenous bradykinin contributes to effects of a combined angiotensin receptor blocker/neprilysin inhibitor (LCZ696 or Entresto)

NCT ID: NCT02985268 Withdrawn - Heart Failure Clinical Trials

Evaluation of Outcomes of CRT and MitraClip for Treatment of Low Ejection Fraction and Functional Mitral Regurgitation in HF

Start date: December 2016
Phase: N/A
Study type: Interventional

At present, the optimal treatment strategy for heart failure patients and moderate-to-severe (3+) or severe (4+) mitral regurgitation with a class IIa recommendation for CRT is uncertain.Whether these patents should also be treated for functional mitral regurgitation or with CRT also remains unclear. We therefore propose a randomized 2x2 factorial design in this patient population to understand the the impact of both CRT and transcatheter mitral valve repair with the MitraClip on their functional status and quality of life.
