NCT ID: NCT03254485 Not yet recruiting - Clinical trials for Heart Failure With Preserved Ejection Fraction

A Study of the Effect of IW-1973 on the Exercise Capacity of Patients With Heart Failure With Preserved Ejection Fraction (HFpEF)

CAPACITY-HFpEF
Start date: October 2017
Phase: Phase 2
Study type: Interventional

The objective of the CAPACITY-HFpEF study is to evaluate the safety and efficacy of 3 dose levels of IW-1973 compared with placebo when administered daily for approximately 12 weeks to patients with HFpEF. The study will evaluate the effect of oral IW-1973 on peak exercise capacity in patients with HFpEF, with or without permanent or persistent atrial fibrillation.

NCT ID: NCT03254212 Not yet recruiting - Clinical trials for Chronic Heart Failure

Nocturnal Oxygen Needs and Central Sleep Apnea in Patients With Chronic Heart Failure.

HO2F
Start date: October 1, 2017
Phase: Phase 4
Study type: Interventional

The aims of this study are to 1) determine the optimal levels of O2 flow which prevent nocturnal O2 desaturation while minimizing periods of hyperoxia during the course of nocturnal oxygen therapy (NOXT) in heart failure patients with reduced ejection fraction (HFrEF) patients with CSA/CSR; 2) document whether within-patient EO2F values change over time during NOXT, and identify factors which predict changes in EO2F; and 3) examine how well a conventional stepwise titration procedure compares to a breath by breath titration using an automated O2 titration system in terms of targeted flow rate and night time oxygenation (oxygen desaturation index, time spent at specific SpO2 targets).

NCT ID: NCT03254108 Recruiting - Clinical trials for Congestive Heart Failure

Clinical Pharmacology Trial to Investigate the Dose of OPC-61815 Injection Equivalent to Tolvaptan 15-mg Tablet in Patients With Congestive Heart Failure

Start date: August 2017
Phase: N/A
Study type: Interventional

The dose for intravenous administration of OPC-61815 achieving tolvaptan exposure equivalent to that for oral administration of tolvaptan 15-mg tablet will be investigated by administering OPC-61815 injection 2 to 16mg or tolvaptan 15-mg oral tablet to subjects with congestive heart failure.

NCT ID: NCT03253809 Recruiting - Clinical trials for Congestive Heart Failure

Survey of QRS Frequency at Various Left Ventricular Pacing Sites for Cardiac Resynchronization

Start date: July 12, 2017
Phase: N/A
Study type: Interventional

LV pacing at various sites with recording of ECG and subsequent signal analysis at different sites.

NCT ID: NCT03251183 Not yet recruiting - Clinical trials for Heart Failure With Normal Ejection Fraction

Validation of CMR Against Invasive Haemodynamics in Patients With HFpEF

DECIPHER-HFpEF
Start date: September 2017
Phase: N/A
Study type: Observational

Heart failure (HF) currently affects app. 2% of the western population and app. 10% of people >75 years. In about 50% of patients with symptomatic HF ejection fraction (EF) is preserved (HF-PEF). Once patients develop symptoms, the prognosis is poor with 25% mortality at 1 year and 50% mortality at 5 years. HFpEF is one of the major unresolved areas in clinical cardiology. The diagnosis of HFpEF remains a diagnosis of exclusion and currently no non-invasive measure provides a clear diagnosis. Cardiovascular magnetic resonance (CMR) provides non invasive and radiation free evaluation of heart structure and function. New CMR parameters offer the possibility to describe the underlying pathological and physiological changes associated with HFpEF. The investigators propose to undertake the first systematic comparison between a CMR protocol and invasive haemodynamics as the best possible gold standard, as well as define the histopathological drivers in myocardial biopsies. The investigators will also examine the relations with tissue and serological biomarkers implicated in HFpEF and the role with standard and novel parameters by echocardiography. If successful, this study will provide tools for a reliable and accurate non-invasive characterization of patients with HFpEF, supporting the diagnosis and grading the severity of disease. This study will provide a reference basis for future diagnostic algorithms in HFpEF, both, for CMR and echocardiography, but also for their relative value in comparison to blood markers or invasive testing. In addition to a new pathway to acess the effects of current and novel therapeutic interventions, the investigators see the greatest potential in identifying a disease stage where the myocardial injury may be reversible.

NCT ID: NCT03247829 Not yet recruiting - Heart Failure Clinical Trials

Investigation to Optimize Hemodynamic Management of Left Ventricular Assist Devices Using the CardioMEMS™

Intellect2
Start date: August 15, 2017
Phase: N/A
Study type: Observational

This observational post market study is intended to characterize hemodynamic-guided management of patients with an existing left ventricular assist device (LVAD) to protocol specified target ranges and its impact on functional status, quality of life, and readmissions

NCT ID: NCT03247608 Recruiting - Clinical trials for Coronary Artery Disease

ConnectedHeartHealth - Heart Failure Readmission Intervention

CHH
Start date: November 2015
Phase: N/A
Study type: Interventional

This is a single-center, pilot study that will evaluate the effectiveness of the AHA science based CarePlans and the Ambio Health technology in improving the risk adjusted 30 day readmissions rate, patient compliance, and biometrics. The study will also be used to assess the feasibility of similar heart failure transition programs in the future.

NCT ID: NCT03247361 Recruiting - Heart Failure Clinical Trials

High-intensity vs. Low-intensity Inspiratory Muscle Training in Patients With Heart Failure

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

It is well-known that muscle weakness and deconditioning play an important role in low exercise capacity of patients with HF. Interestingly, not only peripheral muscles are impaired, but also respiratory muscles. Studies have shown that patients with HF may have, in addition to decreasing maximal inspiratory muscle strength and endurance, metabolic and structural impairments in diaphragm fibers. Moreover, exercise capacity and weakness of inspiratory muscles have been associated with low quality of life and poor prognosis, which make the addition of inspiratory muscle training (IMT) reasonable in cardiovascular rehabilitation.The specifications of the loads to be imposed during IMT is the main factor determining the outcome. Studies of IMT have highlighted the need for a fixed inspiratory workload during exercise. Thus, purpose of this report was to perform a randomized clinical trial of the effects of addition of high-intensity vs. low-intensity IMT to combined aerobic and resistance Exercise in patients with heart failure.

NCT ID: NCT03246035 Not yet recruiting - Heart Failure Clinical Trials

Reducing Readmission for Frail Elderly Patients With Decompensated Heart Failure

HFF-ED
Start date: August 2017
Phase: N/A
Study type: Interventional

A randomized study designed to determine whether telephone based interventions can prevent return hospital visits for elderly and frail patients with acute symptoms of heart failure. Specifically, the intervention will improve patients ability to monitor and address self care of heart failure at home.

LINQ for impEdance meAsuremeNt While Off From HF Medication Study

LEAN HF
Start date: September 2017
Phase: Phase 4
Study type: Interventional

The purpose of this non-randomized, cross-over, unblinded, single-center feasibility study is to assess the sensitivity of the LINQ ICM to measure derived-subcutaneous impedance in patients with heart failure during periods when diuretics and/or HF-medication consumption is increased or suspended for 48 hours (up to 72 hours at physician discretion) and to collect safety information related to HF status and to medication consumption changes.
