Filter by:Mechanical circulatory support, specifically implantable continuous flow left ventricular assist device (CF-LVAD) therapy has been established as a viable treatment for rapidly deteriorating patients suffering from end stage heart failure either as bridge or alternative to heart transplantation. However, a large proportion of these patients experience severe complications in the early postoperative period including right ventricular failure or multi organ failure leading to increased mortality. The leading theory explaining these complications involves exaggerated systemic inflammatory response prior to, during and early after CF-LVAD insertion. Among the cytokines IL-6 appears to play a major role. There is increasing demonstration of the efficacy of a cytokine haemoadsorption (HA) technology in attenuating cytokine response and particularly IL-6 in various inflammatory states and emerging data on the safety of the Cytosorb® device in routine and complex cardiac surgery. The study team hypothesizes that Cytosorb® treatment is feasible and safe in heart failure patients undergoing LVAD insertion and that it is effective in attenuating IL-6 secretion with benefit in the wider inflammatory and metabolic response to this high-risk surgery.
Heart failure with preserved ejection fraction (HFpEF) was considered as a heterogeneous disease with multi-organ and multi-system design, which is related to various complications, such as hypertension, obesity and arteriosclerosis. Studies have found that hypertension and obesity are respectively associated with increased arterial stiffness. However, there is still no research investigating the the relationship between blood pressure and arterial stiffness in HFpEF patients with different levels of obesity.
We aim to investigate the hemodynamic effects of weight-adjusted dosing of ketone monoester en patients with chronic heart failure.
The objective of this clinical evaluation is to assess the safety and initial effectiveness of catheter-based unilateral ablation of the right greater splanchnic nerve (GSN) in subjects having heart failure with preserved ejection fraction (HFpEF).
CHF is a most wild-spread and prognostically poor outcome most of cardiovascular and other disease. Despite of significant progress in treatment of CHF for the last years, death from this pathology stayed very high, reaching 60% for men, 45% for women during the 5 years after establishing diagnosis. The purpose of treatment is creating "seamless" system of care the whole continuum stretch CHF, in this connection, the particular relevance take in creating of new way and strategy with IT-technology mHealth. On the whole, mHealth application potentially suggest economic efficiency solution with continuous access for symptoms monitoring, stimulation of patients to self-servicing, self-controlling and achieving better results compare with optimal medical therapy. So, remote monitoring of patients on the base of mobile application must improve clinical and economic efficiency of medical care received. In trial will be studied efficiency of using mobile application for remote monitoring of patients with ischemic etiology HF, also quality of life, commitment to therapy and prognosis (frequency of cardiovascular poor outcomes). Clinical indicators and tests (Quality of Life Minnesota Living with Heart Failure Questionnaire, Hospital Anxiety and Depression Scale, 6-minute walking test) will be evaluated in the beginning of the trial and repeatly after 1 year. Trial financed by Kyrgyz Republic Ministry of Education and Science.
Diabetes mellitus is among the top 10 causes of death worldwide with an increasing incidence. Patients with diabetes are at risk of developing heart failure which is characterised by significant changes in the heart muscle including scarring and thickening. Contraction of the heart involves movement of calcium across the heart muscle and disruption of this process is an early change seen in heart failure. Recently, a drug therapy (SGLT2 inhibitor therapy) in patients with diabetes was shown to benefit patients with heart failure but the mechanisms of benefit are unknown. Our hypothesis is that calcium handling is altered in patients with either type 2 diabetes mellitus (T2DM) or heart failure and that SGLT2 inhibitors can improve this in heart failure irrespective of the presence of T2DM. Scanning the heart using magnetic resonance imaging (MRI) enables detailed assessment of its structure and function by using a new contrast 'dye' containing manganese that has shown advantages over traditional contrast. We plan to further test this new dye as it has the potential to track and quantify improvements in heart function over time and detect changes in calcium handling in the heart muscle, making it an ideal measure to identify the mechanisms of benefit from SGLT2 inhibitor therapy. The study population will comprise patients with heart failure with and without type 2 diabetes, patients with type 2 diabetes without heart failure and healthy volunteers. Baseline comparisons will be made between the four groups before progressing to the randomised controlled trial with heart failure patients only. Patients will have a clinical assessment and blood tests, electrocardiogram, echocardiogram and MRI of the heart at each visit. If successful, this study will give us significant insights into mechanisms of action of SGLT2 inhibitors in heart failure and will enable us to tailor specific treatments in heart failure patients.
This is a prospective, multi-center, open-label clinical trial intended to evaluate the safety and effectiveness of the MobiusHD® in patients with heart failure and reduced ejection fraction.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of heart failure cases with heterogenous cause and variable presentations. The diagnosis of HFpEF required clinical signs and symptoms of HF, normal left ventricular ejection fraction (LVEF) and evidence of diastolic dysfunction. No treatment has been shown in recent major clinical trials having benefits in these patients. One major reason of the poor response to medical treatment is the heterogeneity of HFpEF, which contains many different underline causes. To identify the underlying causes of HFpEF may improve the diagnosis and treatment in these patients. Age-related amyloid deposition has first been reported in 1876 and the following autopsy studies showed the prevalence of senile cardiac amyloid is up to 25%. Recently, it has been recognized that the deposits in senile cardiac amyloid are derived from wild-type transthyretin (TTR). Transthyretin amyloidosis cardiac amyloidosis (ATTR CA) is caused by myocardial deposition of misfolded transthyretin protein. There are 2 types of ATTR classified by genetic mutation including wild-type ATTR (ATTRwt) and familial cardiac amyloid caused by TTR mutation (ATTRm). Multimodality techniques have been developed to assist in the diagnosis of the diagnosis of TTR. Among them, 99mTc-3,3-diphosphono-1,2-propanodicarboxylic acid (99mTc-DPD) scintigraphy is a non-invasive test and it can diagnose TTR from other cause diverse form of cardiac amyloidosis and cardiomyopathy. In the study of Gonzalez-Lopez et al, in 120 HFpEF patients, 16 (13.3%) had positive 99mTc-DPD scan. Four patients with positive 99mTc-DPD scan received endomyocardial biopsy and confirmed cardiac amyloid deposition. ATTRwt could be an important cause of HFpEF and it was often under diagnosed. A recent study in Spain reported that 13% of patents over age of 60 years with HFpEF and left ventricular wall thickness of 12mm or more had ATTRwt. However, the prevalence of ATTRwt among patients with HFpEF is not well-established in Taiwan and Asia. The aim of this study is to determine the prevalence, clinical characteristics, risk factors and outcomes of ATTRwt related HFpEF patients in Taiwan.
Type 2 diabetes is a risk factor of heart failure and cognitive decline. Heart failure at its early stage is often silent. At present, primary prevention for heart failure is not available. Our aim is to identify diabetic patients at risk of heart failure in order to develop personalized preventive strategies. Type 2 diabetes is vascular and metabolic risk factor for cognitive decline though a direct lesional effect but also through an interaction with underlying neurodegenerative lesions. Our aim is to identify diabetic patients at risk of cognitive decline in order to develop personalized preventive strategies
