The CHILISALT Study aimed to explore the effect of angiotensin-neprilysin inhibition on intrathoracic impedance and -derived fluid index in HFrEF patients who had a device for cardiac resynchronization therapy and/or an implantable cardioverter-defibrillator (ICD; Medtronic Inc., Minneapolis, MN) allowing continuous measurement of intrathoracic impedance.

NCT ID: NCT03359161 Not yet recruiting - Heart Failure Clinical Trials

Clinical Utility of Subcutaneous Furosemide in Patients Presenting With Early Signs of Fluid Overload

Start date: January 2018
Phase: Phase 2/Phase 3
Study type: Interventional

This study will evaluate the usefulness of the subcutaneous administration of a new Lasix formulation. 20 patients will be evaluated in the first phase (pilot phase) and depending on the results, an additional 40 patients will be enrolled (Evaluation Phase). Patients with mild to moderate evidence of fluid overload who present to the cardiology service at St Elizabeth's Medical Center, Brighton, Massachusetts (SEMC) will be included in the study. Patients who qualify for thus study will be sent home with the sc2Wear™ Furosemide Infusor therapy for three days. This is a pump that patients place on their abdomen and it then delivers furosemide to the skin. Participants will be visited at home by a visiting nurse who will give them further teaching on the sc2Wear™ Furosemide Infusor. The visiting nurse will also be responsible for obtaining history (symptoms), physical examination (including inspecting the skin for adverse reactions related to the pump), and laboratory draws, supplementation of electrolytes as needed. Patients will be evaluated by the cardiology service of SEMC within 24 hours of the last dose of the sc2Wear™ Furosemide Infusor. If a patient is found to have satisfactorily responded but requires more therapy, an additional 4 days may be prescribed for total of seven consecutive treatments. If additional units are prescribed, patients will be evaluated by the cardiology service of SEMC within 24 hours of the last dose of the sc2Wear™ Furosemide infusion. Also an additionally, up to three-sc2Wear furosemide at home treatments may be used as authorized by the treating physician in case the patient experiences worsening heart failure within 30-days of enrollment (Rescue Treatment). Participants will be seen in clinic for follow up at 30±3 days after the start of the study for a post treatment.

NCT ID: NCT03358303 Not yet recruiting - Heart Failure Clinical Trials

Effects of Telemonitoring on the Outcome of Heart Failure Patients After an Incidence of Acute Decompensation

Start date: February 2018
Phase: N/A
Study type: Interventional

Heart failure is the most rapidly rising cardiovascular disease and has come to be recognized as a growing epidemic. Digital health interventions are the most recent iteration of an effort to promote individualized outpatient care through positive behaviour change theory. The UHN team has developed a highly automated and user-centered smartphone-based system, Medly, which allows for the telemonitoring of patients diagnosed with heart failure. The purpose of this study will be two-fold: 1) to determine if the introduction of Medly within two weeks of discharge will improve self-care management, quality of life, and clinical status, 2) to assess whether Medly will lead to a potential reduction in 30 day readmission rates amongst HF patients in the Toronto Central Local Health Integration Network (TC LHIN), without increasing the average length of stay or visits to the emergency department. These parameters will be measured as secondary outcomes.

NCT ID: NCT03356652 Not yet recruiting - Heart Failure Clinical Trials

Electrical Activation Mapping Guided Tailor Made Approach for Cardiac Resynchronization Therapy

Start date: January 2018
Phase: N/A
Study type: Interventional

Background Cardiac Resynchronization Therapy (CRT) is proven to improve survival and heart function of patient with certain electrical conduction abnormality and heart failure. However, in patient with certain electrical conduction abnormality, a good response is observed in less than 40% in patient receiving CRT. Conventionally the surgical approach of CRT is to implant one pacing lead in the right heart and one in the left heart to resynchronize the contraction and the pacing lead in the left heart is usually placed in the posterior or lateral portion of the left heart. However, this single approach may not be optimal, especially for those patients with conduction abnormality known to have poor response to CRT. Purpose of the clinical investigation The purpose of the Electrical Activation Guided CRT Study is to study the effectiveness of a tailored made approach to CRT procedure by using a noninvasive globally mapping system studying the electrical conduction under different approaches to delivery CRT. The pacing approach that optimally corrects conduction abnormality will be determined before the actual implantation procedure. Conduct of the Investigation This study will include 93 patients with conduction abnormality that known to have a poor response to CRT from Prince of Wales Hospital, Hong Kong.Subjects will be followed up at 3 months and 6 months visit.

NCT ID: NCT03356353 Not yet recruiting - Clinical trials for End Stage Heart Failure

Sildenafil for the Prevention of Right Heart Failure Following LVAD Implantation

Start date: December 2017
Phase: Phase 3
Study type: Interventional

Continuous-flow left ventricular assist devices (LVAD) move blood from the left ventricle (the largest chamber of the heart) to the aorta (the body's main artery) to help the heart better meet the needs of the body and to improve survival for patients with advanced heart failure (HF). The ability of the right ventricle (the large chamber on the right side of the heart) to keep up with the improved blood flow following LVAD greatly effects how well a person does following surgery. It is understood that a high pulmonary artery pressure (pressure in the blood vessel that takes blood from the right side of the heart to the lungs) measured before surgery, indicates that a higher risk of right heart failure exists after LVAD implantation. This is important because right heart failure after surgery is related to longer intensive care unit (ICU) and hospital stays, increased morbidity (other health problems) including organ failure and worse outcomes following heart transplant, and increased death rates. Sildenafil (Revatio®) has been approved by Health Canada in the treatment of pulmonary arterial hypertension (high blood pressure in the lungs) in patients with connective tissue disease. Sildenafil has not yet been approved by Health Canada for the treatment of pulmonary hypertension in heart failure. Sildenafil lowers blood pressure in the lungs and lessens the workload of the right ventricle (the right side of the heart). The purpose of this study is to determine if lowering blood pressure in the lungs, in heart failure patients at risk for developing right heart failure after LVAD implant, lowers the incidence of right heart failure, shortens ICU and hospital stays and reduces morbidity (other health problems) and mortality (death rates). This is an open label, single arm study. Everyone who participates in this study will receive sildenafil before and after LVAD surgery. It is expected that 24 patients who are scheduled to have LVAD implantation for advanced heart failure will be enrolled from 6 sites across Canada. Participants will be followed in the study for about 2 months.

NCT ID: NCT03356288 Recruiting - Asthma Clinical Trials

The General Breathing Record Study

Start date: August 9, 2017
Phase: N/A
Study type: Observational

NCT ID: NCT03354689 Recruiting - Clinical trials for Cardiovascular Abnormalities

Transcutaneous Electrical Nerve Stimulation and Cardiac Sympathetic Overdrive in Heart Failure

Start date: March 20, 2017
Phase: N/A
Study type: Observational

Introduction: Cardiac sympathetic drive provides inotropic support to the failing heart and preserves cardiovascular homeostasis. Nonetheless, as myocardial insult evolves, this compensatory response leads to a progressive decline in contractile function, increases the vulnerability to arrhythmias and constitutes an independent mortality predictor. Despite advanced pharmacological therapies, side effects and persistent cardiac sympathetic overdrive highlights the modulation of the adrenergic system as a primary target for non-pharmacological strategies in the heart failure (HF) treatment. In this scenario, we will propose cervicothoracic transcutaneous electrical nerve stimulation (TENS) as a non-pharmacological therapy to attenuate cardiac sympathetic overdrive in patients with heart failure. Methods: In this prospective, randomized, sham-controlled, double-blind crossover trial, ten (10) HF patients under optimal pharmacological treatment will be randomly assigned to either an in-home cervicothoracic transcutaneous electrical nerve stimulation therapy (TENS: 30 min twice a day with 80 Hz frequency and pulse duration of 150 μs) or a sham control intervention (SHCI) for two weeks. Following a two-month washout phase from TENS/SHCI, patients crossed over and started the opposite condition. Washout rate and heart-to-mediastinum ratio (planar 123l-metaiodobenzylguanidine myocardial scintigraphy images), indexes of cardiac sympathetic activity and innervation density, muscle sympathetic nerve activity (microneurography) and brachial artery blood flow (Doppler ultrasound) during dynamic handgrip exercise will be obtained at the beginning and end of each condition.

CarDiac MagnEtic Resonance for Primary Prevention Implantable CardioVerter DebrillAtor ThErapy: an International Registry (DERIVATE)

Start date: January 2010
Phase: N/A
Study type: Observational

The DERIVATE study was conceived to integrate the information resulted from clinical data, transthoracic echocardiography, and cardiac magnetic resonance (CMR) imaging to provide a more reliable risk stratification in patients affected by heart failure (HF) and worthy of prophylactic implanted cardioverter defibrillator (ICD) therapy. The main purposes of this multicenter registry are to: 1) determine CMR findings, and specifically late gadolinium enhancement (LGE) features, T1 mapping, and extracellular volume (ECV) that predict sudden cardiac death (SCD) and ventricular arrhythmia; 2) provide a comprehensive clinical and imaging score that effectively improves the selection of patients who deserve a prophylactic ICD therapy; 3) evaluate the contribution of machine learning to predict major adverse cardiac events (MACE) as compared to standard clinical scores.
