Clinical and Economic study of some new biomarkers in chronic heart failure.
To confirm the non-inferiority of OPC-61815 16-mg injection to tolvaptan 15-mg tablet using as the primary endpoint the change in body weight following 5-day intravenous administration of OPC-61815 16-mg injection or 5-day oral administration of tolvaptan 15-mg tablet to CHF patients with volume overload despite having received diuretics other than vasopressin antagonists
This paper will mainly present the renal results from a clinical study aimed to observe the effect of sacubitril/valsartan in advanced chronic kedney disease patients with heart failure.All patients will receive LCZ696.The results will be compared before and after treatment.
Heart failure (HF) is a clinical syndrome caused by structural and/or functional cardiac abnormalities, resulting in a reduced cardiac output and/or elevated intra-cardiac pressures at rest or during stress. It is the leading cause of hospitalization in Internal Medicine departments. This study aims at exploring evidence of the importance of ultrasound in HF both for hospitalized patients and in the follow up. Ultrasound may be used as a recovery monitoring instrument at the bedside and also as a global cardiovascular assessment tool for these patients. HF represents an exciting opportunity to create an integrative ultrasound approach in Internal Medicine/Geriatric departments.The Authors plan a five-step ultrasound examination to evaluate and monitor HF patients during hospitalization and follow-up. They call this examination: the "ABCDE" score. It includes the evaluations of A, the Ankle-brachial index (ABI), B, the B-lines, C, the Carotid intima media thickness (CIMT), D, the Diameter of the abdominal aorta and of the inferior cave vein and E, the echocardiographic assessment of the ejection fraction.This score represent an integrative ultrasound approach in Internal Medicine/Geriatric departments.
Cardiac Resynchronisation Therapy (CRT) is a well-known treatment for patients with heart failure. It is a special pacemaker that consists of three pacing wires, which are implanted in the right upper and bottom chambers of the heart and via a vein on the surface of the main pumping chamber (left bottom chamber). CRT helps by improving co- ordination between the top and the bottom chambers of the heart. By stimulating the heart from the left and right bottom chambers, co-ordination can be restored and heart function as well as symptoms improve. It is known that up to 30-40% of patients of patients undergoing CRT pacemaker implantation do not attain any benefit. Given the inherent risks and costs of pacemaker implantation and maintenance, a reduction in the rate of CRT "non-responders" is an important goal. It has been suggested that presence of scar tissue in the heart and suboptimal placement of the pacing wire on the top of the main pumping chamber can explain this poor response. The best place to position the pacing wire on the surface of the main pumping chamber is the area that contracts last and it can be identified using ultrasound scan of the heart. Unfortunately, ultrasound is not always possible to help identifying the best area and only a minority of hospitals are able to use this method. Therefore we aim to investigate alternative ways of positioning the pacing wire in the best possible area of the main pumping heart chamber. Investigators propose to measure electrical signals as an alternative and more effective way in positioning the wire in the most effective area. Investigators aim to look at the relationship between the best area identified by ultrasound scan and by electrical signals and also use electrical signals to avoid areas of scar.
In patients with weak pumping function of the heart, uncoordinated contraction of the chambers can be corrected using a cardiac resynchronization therapy (CRT) pacemaker. These devices make patients live longer by improving how the heart pumps and reducing symptoms such as breathlessness. However, not all patients benefit from CRT and programming devices optimally can greatly influence success. Predicting the correct timings of contraction between the atria (top chambers of the heart) and the ventricles (bottom chambers), as well as between the left and right ventricles, especially when heart rate increases during exercises, is challenging. A new approach to optimizing CRT programming has been proposed known as 'fusion-pacing'. This allows the electrical wave from the heart's own conduction system to merge or fuse with the impulse from the pacemaker in the left ventricle. The timing of the pacemaker's impulse is continuously adjusted to measurements the device makes of the hearts natural conduction. What is not clear is how effective 'fusion-pacing' is during exercise when the hearts natural conduction changes rapidly and unpredictably. We plan to investigate this by monitoring the electrocardiogram (ECG) whilst accurately measuring exercise performance and ability during a cardiopulmonary exercise test (CPET) on an exercise bike. We will also ask participants to rate their perceived exercise intensity to see whether fusion pacing improves ECG resynchronization, exercise performance, and patients' symptoms compared to standard programming.
Patients with STEMI post-revascularization therapy suffered from various clinical outcomes. Non-invasive imaging, including echocardiography, MPS using SPECT or PET, and CMR, has been proved to be of great predicting value in prognosis. The purporse of this registry is to assess the prognostic value of multi-modality imaging-derived indices.
The primary objective of this study is to assess the safety and key electrical performance of the INVICTA leads equipped with DF4 connector: ACTIVE fixation type models (single and dual coil: INVICTA 1CR, INVICTA 2CR) and PASSIVE fixation type models (single and dual coil: INVICTA 1CT, INVICTA 2CT).
Rehospitalizations due to exacerbation of chronic heart failure are an important problem for patients suffering from heart failure. Rehospitalzations lead to worse prognosis, have an impact on the quality of life and have a negative financial impact on the health care system. Currently, studies are being conducted on the efficacy of levosimendan in the prevention of heart failure exacerbations. Patients receive levosimendan at repetitive use and preliminary results suggest a reduction in the incidence of exacerbations of heart failure. Thanks to the clinical trial planned in the Department of Cardiology of the Biziel Hospital with repeatable use of levosimendan, it is possible to determine the benefits of this method of treatment more accurately.
Heart failure has a high morbidity and mortality because the heart is one of the least regenerative organs in a human body. Drug treatments for heart failure manage symptoms but do not restore lost myocytes. Cellular replacement therapy is a potential approach to repair damaged myocardial tissue, restore cardiac function, which has become a new strategy for the treatment of heart failure. The purpose of this study is to assess the safety, feasibility and efficacy of intramyocardial delivery of regenerated cardiomyocytes at the time of coronary artery bypass grafting in patients with chronic ischemic cardiomyopathy.
