Secondary outcomes are quality of life, NYHA functional class, glomerular filtration rate, renin plasmatic activity, aldosterone and composite clinical outcome (all-cause mortality and cardiovascular hospitalization)

NCT ID: NCT03305692 Recruiting - Clinical trials for Heart Failure, Systolic

ECG Belt vs. Echocardiographic Optimization of CRT

Start date: October 31, 2017
Phase: N/A
Study type: Interventional

Cardiac resynchronization therapy (CRT) has been a valuable intervention for patients with systolic heart failure for over 15 years. Despite years of research, there is a still a 25-40% non-responder rate depending on the outcomes measured. CRT optimization is a term used to describe the act of individualizing the therapy (CRT programming) for an individual patient. This is not often performed, but when it is, echocardiography is utilized. Recent work of body surface mapping using a novel system called the ECG Belt has shown a relationship between measures of electrical dyssynchrony and acute and chronic heart pumping function. This study will compare outcomes of patients randomized to either echocardiographic or ECG Belt optimization of CRT devices.

Start date: August 31, 2017
Phase: N/A
Study type: Interventional

NCT ID: NCT03220659 Recruiting - Clinical trials for Heart Failure, Systolic

Optimising Pacemaker Therapy Using Multi-point Pacing (the OPT-MPP Study)

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

Recently, the introduction of quadripolar left ventricular leads (one with four pacing poles) has allowed the opportunity to pace the lateral (back) of the heart from several points at once using a single lead (multi-point pacing - MPP). Although it seems logical that electrical beginning at several points on the left ventricular wall should improve coordination of the heart, there is no consistent response in terms of improved remodeling (cardiac structure and function) or composite scores of patient-related status. The technology has a further disadvantage that it leads to accelerated battery drain, with on average one year less longevity over the lifetime of the device. Aims are: 1. to explore the effect of MPP on the force-frequency relationship, 2. to examine the effects of MPP on exercise capacity measured by treadmill walk time and whether these are related to the FFR response to MPP in individual patients, 3. establish whether the acute contractile response is maintained to 6 months after the implant procedure and 4. determine whether the acute contractile response to MPP is associated with subsequent beneficial remodeling over a further six months.

NCT ID: NCT03183323 Recruiting - Clinical trials for Chronic Kidney Diseases

Implementation of Telerehabilitation In Support of HOme-based Physical Exercise for Heart Failure

Start date: June 8, 2017
Phase: N/A
Study type: Interventional

ITISHOPE4HF is a randomized controlled trial of telerehabilitation in a heart failure population. The goal is to evaluate if a home-based telerehabilitation project can increase physical activity in heart failure patients. Patient will be provided telerehabiliation or advice on physical activity (standard care).

NCT ID: NCT03183011 Recruiting - Clinical trials for Heart Failure, Systolic

Cardiac Magnetic Resonance Imaging After Cardiac Resynchronization Therapy

Start date: November 1, 2016
Phase: N/A
Study type: Interventional

This study is evaluating how MRI after CRT can provide key insights regarding LV function, structure, and mechanics resulting from CRT in patients with or without LV scar and inform optimal pacing strategies. The expected accurate and reproducible response assessment with cardiac MRI has important implications for evaluating CRT outcomes in clinical trials, and the insights from the post-CRT MRI promise to improve implementation of CRT.

NCT ID: NCT03157219 Recruiting - Heart Failure Clinical Trials

Manipal Heart Failure Registry (MHFR)

Start date: September 10, 2015
Phase: N/A
Study type: Observational [Patient Registry]

Burden of HF in India is approximate 2-5 million patients with an estimated prevalence of 2-3/1000 population. HF is responsible for approx1.8 million admissions annually in India. Very few studies are there in India which shows the detailed documentation of HF. Manipal Heart failure Registry (MHFR) is an institutional level Heart Failure disease registry. In MHFR the investigator will document the detailed information about heart failure patients admitted or referred to Department of Cardiology, Kasturba Medical College, a constituent college and teaching hospital of Manipal University. MHFR will include cohorts of patients with acute heart failure (AHF), with the intention of implementing a long-term follow-up, the use of health economic assessment to evaluate the degree of resource utilization; and quantifying the burden on quality of life for patients. Utilization of drug in HF patients will be evaluated as a part of this study to prevent the use of inappropriate drug therapy and to improve overall drug effectiveness and outcomes. Hence the protocol sought to identify the characteristics and long-term outcomes of Indian patients with acute heart failure admitted in an Indian tertiary care center in South India. There are no risks to patients participating in the registry study, as standard of care quality will not be affected. It is unlikely that there will be any direct benefit as a result of participation in the HF-disease registry. However, the information contained within this non-interventional registry study will be used for research studies directed at improving the knowledge and treatment of acute heart failure as well as improving patients treatment in the future. The potential impact of proposed research (Manipal Heart Failure Registry) is envisioned to be four-fold: 1. to enable a broad overview of the routine medical practices for HF treatment; 2. to assess the healthcare resource utilization and drug utilization review for heart failure patients 3. to assess the burden of disease (mortality, re-hospitalization) in the long term; and 4. to provide a novel overview of the impact of HF syndrome on quality of life as well as health economics.

NCT ID: NCT03122769 Recruiting - Clinical trials for Heart Failure, Systolic

Cardiac Uptake of Metformin, Visualized by Positron Emission Tomography

Start date: April 20, 2017
Phase: Phase 1
Study type: Interventional

The purpose of the study is to evaluate if metformin is taken up into the failing myocardium. Recent experimental and epidemiological studies have shown beneficial effects of metformin on heart failure. It is unknown whether this effect is direct or indirect. The aim of the study is to investigate if metformin is taken up in heart failure using a novel 11C-metformin tracer and positron emission tomography (PET).

NCT ID: NCT03089502 Recruiting - Breast Cancer Clinical Trials

Efficacy of Cardio-Oncology Rehabilitation Exercise for Women With Breast Cancer and Treatment Related Cardiotoxicity

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

Breast cancer is the leading cause of cancer among Canadian women with nearly 26,000 new cases diagnosed each year. Fortunately, advancements in diagnostic tools and curative treatments have significantly improved overall survival. However, the development of cardiac toxicity (including asymptomatic and symptomatic heart failure) associated with use of anthracycline containing chemotherapy and targeted therapies including trastuzumab limits improvements in survival for women with breast cancer. Cardiac toxicity is a life threatening complication that leads to reduced physical functioning and quality of life. The increased risk is associated with shared risk factors among cancer and heart failure and the direct influence of cancer therapy on the cardiovascular system. Cardiac rehabilitation (CR) (including exercise training and education/counselling) has been shown to improve health outcomes, reduce heart failure related hospitalizations and modestly improve mortality among individuals with non-treatment related heart failure and may benefit women with breast cancer and treatment related cardiac toxicity (BC-CT). Therefore, this single centre, randomized control trial aims to determine if participation in an exercise based CR program can improve cardiorespiratory fitness, cardiovascular function/structure and health, and quality of life among women with BC-CT.

NCT ID: NCT03086746 Not yet recruiting - Clinical trials for Myocardial Infarction

VItamin D as a Novel Determinant of Injurious Cardiac Remodelling After acuTE Myocardial Infarction

Start date: December 1, 2017
Phase: N/A
