Active clinical trials for "Heart Failure"

This study is an exploratory clinical study to observe the improvement of heart function before and after the treatment by human umbilical cord mesenchymal stem cells, and the purpose is to evaluate the safety and effectiveness of human umbilical cord mesenchymal stem cells in the treatment of heart failure. The study is a randomized parallel controlled study. Patients receive a review of which main content includes symptom improvement, cardiac function improvement, and adverse events.

The effects of home noninvasive ventilation on renin-angiotensin system (RAS), kallikrein-kinin system (KKS) and cardiac remodeling in patients with chronic stable heart failure have not been reported. This project aims to clarify the efficacy and safety of home non-invasive ventilation in patients with chronic heart failure complicated with sleep-disordered breathing. First, patients with chronic stable heart failure were selected and monitored by polysomnography. Patients with sleep apnea hypopnea syndrome (SAHS, AHI≥15) were randomly divided into two groups: the treatment group was treated with non-invasive ventilator at home (≥5h/ night); The control group was only given routine treatment. After 6 months of follow-up, the effects of sleep disordered breathing and noninvasive ventilation on RAS, KKS, cardiac remodeling and function and cardiovascular adverse events in patients with chronic heart failure were evaluated. The results are helpful to further reveal the role of sleep disordered breathing in the occurrence and development of chronic heart failure, and provide a new diagnosis and treatment strategy for chronic heart failure.

The purpose of this study is to assess whether clinical ultrasound (CU)-guided treatment in acute heart failure (AHF) is superior to the standard care (SC)-guided treatment. We would like to see if using a portable ultrasound to guide diuretic therapy for AHF patients will prevent hospital readmissions in the setting of hospitalization at home (HAH). This study will use a handheld ultrasound called IVIZ-Sonosite and aims to see whether changing diuretic therapy based on the performance of the ultrasound will result in the less hospitalizations for heart failure as compared to performing just SC-guided therapy.

The effectively therapeutic approaches for Heart failure with preserved ejection fraction (HFpEF) remain limited. The PARAGON-HF trial found that Angiotensin Receptor-Neprilysin Inhibition (ARNI) has potential benefits for the management of HFpEF. Nevertheless, the role of ARNI in cardiac fibrosis in HFpEF are still unclear. We will conduct a prospective randomized controlled trial to evaluate the effect of ARNI on cardiac fibrosis in patients with HFpEF by cardiac magnetic resonance (CMR).

Type 2 diabetes mellitus (T2DM) is a well-recognized independent risk factor for heart failure (HF). Whereas the prevalence of HF in the general population is 1-4%, it reaches approximately 12% in T2DM patients. In 1972, Rubler reported a specific diabetes-associated cardiac injury called diabetic cardiomyopathy. This cardiomyopathy is defined by ventricular dysfunction occurring without coronary disease or hypertension. Diabetic cardiomyopathy is also characterized by left ventricular (LV) hypertrophy, diastolic dysfunction and myocardial fibrosis. A large body of work indicates that diabetic cardiomyopathy is associated with altered cardiac energy metabolism. Indeed, in obese T2DM patients, heart lipid uptake is increased. Several studies support that free fatty acid (FFA) accumulation leads to the increased production of diacylglycerol (DAG), ceramides and reactive oxygen species (ROS), affecting cardiac insulin sensitivity and cardiac contractility. On the other hand, hyperglycemia and glucose overload have been involved in cardiac hypertrophy and dysfunction in the context of T2DM and obesity. The diabetic heart is simultaneously characterized by impaired insulin-stimulated glucose uptake and obvious signs of glucose overload, such as ROS and advanced glycation end-product (AGE) production as well as hexosamine pathway chronic activation. Interestingly, when comparing diabetic and nondiabetic obese patients, we previously demonstrated that hyperglycemia per se plays a central role in the impaired cardiac mitochondrial activity associated with myocardial contractile dysfunction.

It was aimed to examine whether the arm endurance exercise training is effective in addition to the lower cycling training program in order to alleviate the negative functional results in heart failure patients with ICD.

Aim of this clinical study is to compare our newly developed control algorithms for mechanical circulatory support devices based on physiological demand with the standard manual LVAD speed operation. Specifically it shall be demonstrated that: Suction is properly detected by the pre-trained pump flow estimation algorithm Suction events (due to changes in physiological demand) can be reduced by control algorithms compared to continuous speed If suction is encountered, it can be detected and cleared The pump reacts adequately to changes in patient demand due to physical activity Physicians pump setpoints (of requested speed for a certain heartrate) can be achieved safely.

This is a prospective, single-arm, unblinded pilot study and registry that aims to demonstrate adherence to adaptive servo-ventilation (ASV) therapy in patients with moderate to severe sleep disordered breathing who have been recently hospitalized. ASV therapy has been linked to improved outcomes in this population, but adherence to therapy is low. The AirCurve 10 ASV device that will be used for this study employs newer technologies, such as web-based monitoring and provides patients feedback, which may increase therapy adherence and therefore improve patient outcomes.

The purpose of this study is to determine acute effect the transctutaneous electrical nerve stimulation in sympathetic and parassympathetic system in individuals with heart failure.

The purpose of this study is to determine whether direct endomyocardial injection of autologous bone marrow cells is effective for enhancement of neovascularisation in patients with ischaemic heart failure.
