Study type: Observational

Observational and perspective study with acute and chronic endpoint.

NCT ID: NCT04872959 Withdrawn - Clinical trials for Heart Failure, Systolic

TRANSFORM Heart Failure With Reduced Ejection Fraction

TRANSFORMHFrEF
Start date: October 2021
Phase: N/A
Study type: Interventional

The goal of the TRANSFORM-HFrEF trial will be to study the current guideline-directed medical therapy (GDMT) landscape for HFrEF and determine effective methods and models of increasing adherence to GDMT and improving Quality of Life (QOL) in outpatient settings within the context of the 20-minute visit. This will be achieved through a randomized evaluation that shifts standard clinical interview and documentation requirements outside the office visit and building the patient and physician relationship through trust and shared goal setting. Specific Aims: To evaluate the ability of ACC Solution Sets and Patient Resources to improve initiation and titration of GDMT for eligible patients with HFrEF Left Ventricle Ejection Fraction (LVEF) ≤ 40%. To evaluate change in QOL between patients in the intervention arm and the Usual Care arm. Examine the relative change in GDMT among higher risk versus lower-risk patients in the Intervention arm and Usual Care arm. In this randomized registry trial, sites will be invited to participate in a 6-month study aimed at various processes of care in HFrEF. Sites would be informed that they might be asked to participate in an intensive intervention to improve GDMT prescription or in a study of QOL in HFrEF. Once a list of sites interested in participating is created, sites would be randomized into two arms: an intervention group and a usual care group.

NCT ID: NCT04839133 Completed - Pulmonary Disease Clinical Trials

Robotic-assisted Exercise Training in Heart Failure

Start date: March 31, 2021
Phase: N/A
Study type: Interventional

Background: Regular physical activity is an evidence-based adjuvant therapy of chronic heart failure or chronic lung diseases. Structured exercise training is safe, increases exercise capacity and quality of life, relieves symptoms and reduces hospitalization rates. Even a trend towards reduction of mortality has been identified. However, dyspnea and fatigue, typical symptoms of heart or lung failure, force patients to physical inactivity which fatally aggravates deconditioning and exercise intolerance, leading to an increased risk of hospitalization and a loss of independence and quality of life. To break through this vicious circle physical activity must be restored, since exercise intolerance can be successfully improved by physical training. Purpose: This study will address the challenging task of remobilizing patients with advanced chronic lung or heart failure in a functional New York Heart Association class III-IV by using an externally physically-supported exosuit movement therapy. This soft, wearable robot (fig. 1) assists mobilization according to individual needs by activating neuromuscular feedback systems, promoting physical activity and preventing early physical exhaustion. The investigators hypotheses that an exosuit-supported training increases exercise capacity and quality of life in a greater degree than non-supported training. Methods: The study will consist of two parts investigating i) the feasibility, tolerance and safety (n= 30) and ii) the efficacy of an exosuit device-supported training (n=30). In i) patients will perform a walking test and a set of everyday life skills or participate in a standardized rehabilitation sports program. In ii) patients will be randomized in a 2:1 ratio for an exosuit-supported or non-supported exercise training protocol, training 3 units per week for 8 weeks. Assessment of outcome will be performed by various functional, mobility and endurance tests, questionnaires and clinical parameters. Furthermore, the transfer of regained motor and balance skills to everyday life will be analyzed.

Sacubitril/Valsartan Versus Valsartan in Heart Failure With Improved Ejection Fraction

PROSPER-HF
Start date: March 16, 2021
Phase:
Study type: Observational [Patient Registry]

Heart failure (HF) is a chronic disease with weakened heart muscles or abnormal pressure within the heart chambers result in breathlessness, leg edema, or fatigue. A subclass of HF shows reduced heart muscle contractility, which is represented by the left ventricular ejection fraction (LVEF). Valsartan is an angiotensin II receptor blocker, a major drug class for heart failure. Sacubitril/valsartan is a combination of 2 drugs, classified as a new class of drug called angiotensin receptor neprilysin inhibitor (ARNI). Although these medications are both first-line treatment in HF with reduced LVEF, recent guidelines encourage the use of sacubitril/valsartan in patients with ongoing symptoms. After successful treatment, some patients experience recovery of LVEF. In these patients, otherwise called heart failure with improved ejection fraction (HFiEF), it is not clear whether continued treatment with sacubitril/valsartan or valsartan is beneficial in terms of relapse of heart failure or worsening of LVEF. Therefore, the investigators aim to determine whether the treatment with sacubitril/valsartan versus valsartan differs in clinical outcomes after 1 year in HFiEF patients by observing the change in blood test markers of heart failure (N-terminal prohormone of brain natriuretic peptide; NT-proBNP) and aggravation of HF defined as reduced LVEF, congestive symptoms, hospitalization or death from HF.

NCT ID: NCT04763460 Recruiting - Clinical trials for Heart Failure, Systolic

Effects of CRT Optimization as Assessed by Cardiac MR

Start date: July 1, 2021
Phase: N/A
Study type: Interventional

Cardiac resynchronization therapy (CRT), or atrial-synchronized biventricular (BiV) pacing, is an FDA-approved device therapy option for heart failure (HF) patients with reduced left ventricular ejection fraction and electrical dyssynchrony. A traditional CRT device has pacing leads implanted within the right atrium (RA), the right ventricle (RV), and within a coronary vein overlying the lateral or posterior left ventricle (LV). Within the past decade, various multi-center randomized controlled trials have reported improved quality of life, aerobic exercise capacity, LV systolic function and structure, as well as decreased hospitalization rates and mortality among patients with HF. Despite improvements in CRT technology with multipoint pacing, quadripolar leads, and adaptive pacing algorithms, approximately 30% of patients do not clinically benefit and are considered non-responders. This study looks to optimize CRT device programming in patients considered non-responders to CRTusing information obtained from standard ECG machines, and to assess acute and chronic effects of CRT optimization using cardiac magnetic resonance imaging (CMR).

NCT ID: NCT04743063 Active, not recruiting - Frailty Clinical Trials

Prospective Monitoring of Angiotensin Receptor Neprilysin Inhibitor in Older Adults With Heart Failure and Frailty

Start date: January 14, 2021
Phase:
Study type: Observational

The objective of this study is to establish a near-real-time prospective monitoring program in Medicare, Optum and MarketScan Research data to evaluate the benefit of new cardiovascular disease (CVD) drugs for older adults with frailty. Prospective monitoring program seeks to find early effectiveness and safety signals of new drugs by updating the analysis at regular intervals as new Medicare data become available. This study specifically aims to emulate a prospective surveillance of the effectiveness and safety of Angiotensin Receptor Neprilysin Inhibitor(ARNI) vs. a comparator, Angiotensin II Receptor Blockers (ARBs), in older adults with Heart Failure with Reduced Ejection Fraction (HFrEF) and different frailty status. This program will be enhanced by incorporating a novel claims-based frailty index, which has been shown useful in assessing how the benefits and harms of drug therapy vary by frailty.

LEIA-HF
Start date: January 1, 2021
Phase: Phase 4
Study type: Interventional

The objective of the study is to determine the efficacy of repeated infusions of levosimendan in the group of outpatients with advanced systolic heart failure (HF).

NCT ID: NCT04703842 Recruiting - Heart Failure Clinical Trials

Modulation of SERCA2a of Intra-myocytic Calcium Trafficking in Heart Failure With Reduced Ejection Fraction

MUSIC-HFrEF1
Start date: September 23, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

It is believed that targeted SERCA2a enzyme replacement in HFrEF patients will correct defective intracellular Ca2+ hemostasis, resulting in improved cardiac contractile function and energetics which will, in turn, translate to improved clinical outcomes. Additionally, it is hypothesized that correcting SERCA2a dysfunction will also improve coronary blood flow through correction of the impaired endothelium-dependent nitric oxide-mediated vasodilatation observed in heart failure.

NCT ID: NCT04703361 Completed - Clinical trials for Heart Failure, Systolic

Effects of Ketones and Niacin in Heart Failure Patients

KETO-COX
Start date: February 15, 2021
Phase: Phase 2
Study type: Interventional

Ketones, 3-hydroxybutyrate (3-OHB), have shown to have beneficial hemodynamics effect in patients with hearth failure with reduced ejection fraction. The mechanisms behind these marked hemodynamic effects are currently unknown, but could involve prostaglandin-release. 3-OHB is the endogenous ligand for the G protein-coupled receptor hydroxy-carboxylic acid 2 (HCA2) receptor. This receptor has proven downstream effects on cAMP and systemic effects via release of prostaglandins. In this present study we will investigate the cardiovascular effects of HCA2-receptor stimulation in heart failure patients.

Acute Hemodynamic Effects of Pacing the His Bundle in Heart Failure

HEPA-His
Start date: September 1, 2021
Phase: N/A
Study type: Interventional

Cardiac resynchronization therapy (CRT) with biventricular pacing (BVP) is indicated for patients with low ejection fraction and persistent symptoms of heart failure despite medical therapy and a wide QRS-complex, preferably with a left bundle branch block. Unfortunately, up to 40 % receiving CRT do not respond with subjective improvement or improved left ventricular ejection fraction from the treatment. There are few therapeutic alternatives in patients not responding to CRT with BVP, and the potential to improve cardiac function in these patients could make a large difference in terms of life quality and prognosis. His-bundle pacing (HBP) can be a suitable alternative, but is likely not possible in all patients with failed CRT. Furthermore, upgrading to HBP does require a surgical procedure and therefore exposes the patients to risk of complications (e.g. infection of the device). Therefore, early identification of the patients who are likely to benefit from an upgrade to HBP would be beneficial. This study aims to evaluate if patients with failed CRT treatment will benefit from hemodynamic improvement if they are treated with temporary HBP, without opening the device-pocket, and exposing the existing pacemaker-device to a risk of infection. A temporary pacemaker lead and pacing sheath will be used, and placed in the heart via a blood vessel on the right side of neck, using local anaesthesia. Acute effects on the pump function of the heart will be measured during rest and during supine bicycle test (the equivalent of moderate physical activity). Factors associated with a beneficial effect will be evaluated on a group basis. If the individual patient experiences an improvement of cardiac function during the test, he/she will be offered an upgrade to HBP and a replacement of the existing device.
