NCT ID: NCT03320655 Active, not recruiting - Clinical trials for Chronic Heart Failure

Effectiveness of Combined Aerobic and Strength Training in Acute and Chronic Adaptations in Patients With Heart Failure

Start date: October 9, 2017
Phase: N/A
Study type: Interventional

Patients with chronic heart failure (CHF) underwent to a hospital-based cardiac rehabilitation (CR) program in the Lisbon district Hospitals will be recruited. The participants will be randomized into one of the following exercise groups: A) combined exercise training with more aerobic training and less strength training (CAT); B) combined exercise training with more strength training and less aerobic training (CST). The investigators will test two proportions in combined training, CAT and CST. There hasn't been any data on the so called combined regimes, which include both aerobic exercise with HIIT and ST and the investigators will evaluate the effects of acute and chronic response. The research project will contribute to a better understanding in several aspects that are unexplained by scientific research.

Na+ Channel mRNA Regulation in Heart Failure

Start date: August 2011
Phase: N/A
Study type: Observational

Human heart failure (HF) has been associated with reduced cardiac sodium channel current and other electrical remodeling. Recently, the investigators have shown that downregulation of cardiac Na+ channels (SCN5A) can contribute to arrhythmic risk and that upregulation can mitigate that risk. Furthermore, the investigators have shown that the reduction in cardiac SCN5A mRNA abundance is reflected in circulating white blood cells (WBCs), which also express SCN5A, and that a reduction in SCN5A is highly predictive of appropriate implanted cardiac defibrillator (ICD) therapy. These data suggest that SCN5A regulation contributes to arrhythmic risk in HF. Other electrical remodeling events thought to contribute to arrhythmic risk include reductions in K+ currents, including Ito, IK1 and IKs are responsible. These current reductions have been linked to reduced transcription, translation and expression of the corresponding channel subunits, such as Kv4.3, Kir2.1, KvLQT1, and accessory proteins including minK and K+ channel interacting protein 2. That all these ion channels are downregulated may suggest a common mechanism to reduce ion channel expression. In this application, the investigators intend to explore an entirely novel mechanism by which SCN5A and other ion channel mRNA abundances are reduced in HF.

NCT ID: NCT03294811 Active, not recruiting - Heart Failure Clinical Trials

A Two-way Communication System to Coach Elderly Patients With Heart Failure

Start date: May 2014
Phase: N/A
Study type: Interventional

This is an open randomized clinical trial with two study arms. One group, receiving usual care for heart failure, will be compared to another group, receiving usual care plus active telemonitoring interference. When leaving the hospital, the usual care arm receives a document with a predefined medication scheme and advice for the general practitioner (like it is currently done in usual care). The telemonitoring interference in the other study arm consists of a smartphone application to register medication intake and to transmit the data of an automatic blood pressure device and a balance to a central platform. The goal is to improve medication uptitration (angiotensin-converting-enzyme inhibitor (ACE-I) and bètablockers (BB)) in heart failure patients and to improve medication compliance.

Start date: February 1, 2017
Phase: N/A
Study type: Observational

FEVRIER study is an observatory of hospitalizations in cardiology units in sub-Saharan Africa.

NCT ID: NCT03210883 Active, not recruiting - Heart Failure Clinical Trials

Global Electrical Heterogeneity and Clinical Outcomes

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

This retrospective multicenter cohort will validate an independent association of electrocardiographic (ECG) global electrical heterogeneity (GEH) measures with sustained ventricular tachyarrhythmias and appropriate ICD therapies in systolic heart failure patients with primary prevention ICD, and will validate and re-calibrate GEH ECG risk score for prediction of sustained ventricular tachyarrhythmias and appropriate ICD therapies in systolic heart failure patients with primary prevention ICD.

NCT ID: NCT03195660 Active, not recruiting - Sleep Apnea Clinical Trials

Adherence to ASV Therapy in Heart Failure With Preserved Ejection Fraction Feasibility Study

Start date: June 26, 2017
Phase: N/A
Study type: Interventional

This study is designed to demonstrate feasibility of study conduct and that acceptable adherence to adaptive servo-ventilation (ASV) therapy can be achieved in recently hospitalized HFpEF patients with moderate to severe sleep apnea. All subjects meeting the criteria will receive ASV therapy.

NCT ID: NCT03138122 Active, not recruiting - Clinical trials for Cardiovascular Diseases

The Study of Men Born in 1943

Start date: February 9, 1993
Phase: N/A
Study type: Observational

A random sample a random sample of half of all men born in 1943 and living in the city of Gothenburg, Sweden, have been investigated in 1993 at 50 years of age and will be followed continuously with repeated re-examinations and follow-up concerning mortality and cardiovascular diseased. Out of 1463 invited men, 798 (54.5%) accepted the invitation and is included in this longitudinal cohort study.

NCT ID: NCT03121183 Active, not recruiting - Heart Failure Clinical Trials

Medico-economic Evaluation of Strategies for the Lead Extraction of Implantable Defibrillator and Pacemakers

Start date: March 2015
Phase: N/A
Study type: Observational

The growing use and the expanding indications for cardiovascular implantable electronic devices (CIEDs) have been associated to an increase of device removal. The indications of CIEDs removal are infectious (55%) or noninfectious (45%) such as upgrading of devices, nonfunctional devices and thrombosis. Removal can be performed according to transvenous or surgical procedures. Transvenous lead removal (TLR) must be done by experimented cardiologists and respecting current consensus. TLR can be done with conventional techniques involving inserting locking stylets and telescoping sheaths around the pacing leads to separate them from the surrounding scar tissue. These conventional procedures have a success rate of ≈65%. TLR thanks to laser sheath has been validated and improved the success rate until >95%. However, the TLR from chronically implanted CIEDs still carries a significant risk of procedural failure, morbidity, and mortality, related to tearing of the great vessels and cardiac structures, even when performed by experienced operators. Even if the transvenous extraction using laser sheath seems to be more effective, this strategy would be more expensive. Considering the availability of several strategies for TLR and the cost heterogeneity of procedures, a cost assessment in real life of these therapeutic strategies is essential for an optimal choice of therapeutic strategies.

NCT ID: NCT03112109 Active, not recruiting - Clinical trials for Congestive Heart Failure

SMARTCARE Project: Deploying Integrated Health & Social Services for Independent Living by Older People

Start date: March 1, 2014
Phase: N/A
Study type: Observational

Against the background of the European Innovation Partnership on Active & Healthy Ageing, SmartCare aims to define a common set of standard functional specifications for an open ICT platform enabling the delivery of integrated care to older European citizens. In the context of SmartCare, a total of 23 regions and their key stakeholders will define a comprehensive set of integration building blocks around the challenges of data-sharing, coordination and communication. Nine regions will then deploy integrated health & social services to combat a range of threats to independent living commonly faced by older people, while the others will prepare for early adoption, possibly in the framework of new ICT PSP projects. In a rigorous evaluation approach, the deployment sites will produce and document much needed evidence on the impact of integrated care, developing a common framework suitable for other regions in Europe. The organisational and legal ramifications of integrated care will be analysed to support long term sustainability and upscaling of the services. SmartCare services will provide full support to cooperative delivery of care, integrated with self-care and across organisational silos, including essential coordination tools such as shared data access, care pathway design and execution, as well as real time communication support to care teams and multi-organisation access to home platforms. In addition, they will empower all older people according to their mental faculties to take part in effective management of their health, wellness, and chronic conditions, and maintain their independence despite increasing frailty. The SmartCare services build on advanced ICT already deployed in the pioneer regions, including high penetrations of telecare and telemonitoring home platforms. In SmartCare, these platforms are to be opened to cross-sectorial care teams, improving the ability of older people to better manage their chronic conditions at home and deal with their increasing frailty. System integration will be based, whenever possible, on open standards' multivendor interoperability will be strongly encouraged.
