Filter by:Ivabradine acts by inhibiting the ionic If current that modulates the pacemaker activity of sinoatrial node cells. The aim of present study is to evaluate the efficacy and safety of IvabRadine hemisulfate Sustained-release Tablets versus placebo in patients with moderate to severe chronic systolic heart failure.
In this study we will select twenty patients with chronic atrial fibrillation and ventricular dysfunction with permanent cardiac pacemaker indication. We will dosage serum level natriuretic peptides for comparison between conventional and bifocal cardiac pacing.
Patients with Ischaemic and Dilated Cardiomyopathy, face an increased risk for Arrhythmic Sudden Cardiac Death. The purpose of this study is to estimate the performance of Modern Non-Invasive Indices and the performance of Programmed Ventricular Stimulation in Sudden Cardiac Death Prediction.
Rationale: Palliative care integration in treatment pathways, palliative care networks and institutional collaborations in health services delivery seems a promising approach reducing fragmentation and discontinuity. Integrated Palliative Care (IPC) approaches in Europe are largely unknown and under-investigated. The investigators aim is to explore experiences of patients with advanced cancer, Chronic Obstructive Pulmonary Disease (COPD) and Chronic Heart Failure (CHF), family and professional caregivers within with IPC. This includes perceived quality of life, quality of care, burden/rewards of care giving, symptoms and collaboration between caregivers in the patient's care network. Objectives: To investigate how patients with advanced cancer, COPD and CHF, their family and professional caregivers within a selection of IPC initiatives in Belgium, Germany, Hungary, The Netherlands and United Kingdom experience care delivery in the last phase of disease. - To investigate what opinions patients and family caregivers have on the (continuity and) quality of care delivered - To investigate how patients rate their symptoms and quality of life - To investigate how family caregivers rate their burden / rewards of care giving - To investigate how the care network of the patient is organised with respect to the type, properties and quality of relationships between patients and family / professional caregivers Study design: Longitudinal multiple embedded case study. Study population: Adult patients with advanced cancer, COPD, and CHF under the care of IPC initiatives in five participating countries, their family and professional caregivers. The investigators aim to enroll up to 288 patients, 288 family caregivers and 192 professional caregivers in total. Study parameters: Experiences with IPC initiatives, quality of care, quality of life, perceived symptoms, perceived collaboration between professional caregivers, burden and rewards of care giving. Methods: Semi-structured interviews, patient diary, Social Network Analysis and the following questionnaires: Palliative care Outcome Scale; Canhelp Lite, Caregiver Reaction Assessment. Patients and family caregivers will be followed over 3 months at 4 consecutive contact points. The diary (containing two questions) will be kept weekly by patients. There will be group or individual interviews with professional caregivers. Analysis: The overall analysis will involve a synthesis of the qualitative and quantitative data.

Cardiac resynchronisation therapy (CRT) is an established treatment for severe systolic heart failure with well documented benefits in symptom improvement and reduction of morbidity and mortality. However, upto 30% of patients do not respond to treatment despite fulfilling the recommended indications. Lack of clinical response may be the result of imperfect left ventricular lead placement in the veins around the heart with conventional techniques. Optimum lead placement may constrained by coronary venous anatomy and may overlie scarred heart muscle or may not be at the site of latest electrical depolarisation. In a further 10% of patients, conventional left ventricular lead placement is not possible for other technical reasons. Left ventricular endocardial lead placement may overcome the limitations and allow placement to be guided by echocardiography, electrical mapping and the pattern of heart muscle scarring. We aim to investigate if targeted left ventricular endocardial lead placement improves exercise capacity, heart failure symptoms, heart function and size, heart pumping efficiency and biochemical markers of heart strain. Each parameter will be assessed independently and as part of a composite cardiac performance score. Patients with heart failure will be enrolled who require an endocardial left ventricular lead on clinical grounds as either conventional left ventricular lead implantation has technically failed or they have clinically non-responded to CRT.
Robotic assisted gait therapy with the Lokomat® as a new method for rehabilitation in advanced heart failure and after cardiac surgery.
CRT and ICD has known as decreasing cardiac mortality in patient with heart failure. Especially, it has reported that CRT improved cardiac systolic function, quality of life of patients with heart failure. However, CRT and primary ICD was not generalized in Korea. So the investigators will register patients who implant CRT or ICD (primary), and follow them up. During scheduled follow up, all patients will perform echocardiography, 6 minute walking test, EKG, Holter monitoring and questionnaire on QOL.
The purpose of this study is to investigate the non-inferiority of bisoprolol to carvedilol by evaluating tolerability (The probability that administered maintenance dose reaches the maximum will be determined as an indicator) as a primary endpoint when bisoprolol or carvedilol is administered for 48 weeks to Japanese chronic heart failure patients. In addition, the safety and efficacy of bisoprolol will be investigated.
It is a randomized prospective controlled study of transcatheter renal denervation in patients with Heart Failure With Normal LV Ejection Fraction. The purpose of the study is to evaluate the safety and effectiveness of renal denervation in patients with Heart Failure With Normal LV Ejection Fraction, due to reduction in renal and systemic sympathetic activity.
Advanced heart failure (when the heart pump fails) is associated with symptoms such as shortness of breath and extreme fatigue. Some of these symptoms are simply due to failure of the pump, however abnormal regulation of blood flow to the muscles of the body is also a potential mechanism. Left ventricular assist devices are mechanical pumps used to compensate for patients with failing hearts either as a bridge to heart transplant or as long term therapy. Whether or not these pumps improve muscle flow and whether this is a determinant in the improvement of symptoms is unknown. Understanding how skeletal muscle and heart perfusion is altered in heart failure patients before and after implantation of an LVAD could provide further insight into the beneficial effects of this therapy. Specific Aims: 1. To evaluate skeletal muscle and heart perfusion studies before and after LVAD implantation 2. To compare functional status with degree of skeletal muscle perfusion.
