Filter by:The objective of this project is to assess the effects of combined physical exercise and cognitive training interventions on cognitive and brain health in patients with heart failure (HF). Also, the role of sex on the effects of the interventions will be assessed.
The Exploratory Study of the Edwards Transcatheter Atrial Shunt System is a multi-center, prospective, exploratory study to evaluate initial clinical safety, device functionality, and effectiveness of the Edwards Transcatheter Atrial Shunt System.
To provide new ideas for the treatment of patients with ischemic heart failure, this study is to search for differential metabolic markers associated with ischemic heart failure and to study the influence of fecal flora on the course of heart failure in patients with ischemic heart failure.
This is a prospective study in which a process of identifying and reducing heart failure (HF) risk will be applied to cancer survivors >65 years old with chemotherapy >10 years ago. The overall goal of this study to identify the feasibility and value of risk-guided cardiac rehabilitation (exercise, risk factor modification, and behavioural support) as a component of survivorship care.
Acupuncture is believed to increase blood pressure in people who struggle with low blood pressure. This is a common problem facing people with heart failure, and sometimes these people need to take medications to artificially increase their blood pressure. This study is designed to determine if using acupuncture in people with heart failure can improve their blood pressure enough to not require medications to artificially increase blood pressure.
The primary objective of this study is to determine whether preserved pulsatility for patients supported by CF-LVAD (continuous flow Left Ventricular Assist Device) is associated with less acquired deficiency of the Von Willebrand factor, a blood glycoprotein involved in hemostasis.
Chronic heart failure is the terminal stage of various cardiovascular diseases. It is characterized with high fatality rate and high recurrence rate, which brings a heavy economic burden to patients and society. Although in recent years, the long-term prognosis of patients with heart failure has been greatly improved by the advances in drugs and new techniques, some patients have eventually progressed to refractory heart failure. The newly developed positive inotropic drug levosimendan is a new type of calcium sensitizer, increasing the sensitivity of troponin to calcium ions, without directly increasing the concentration of calcium ions in cardiomyocytes. Levosimendan improves heart function by increasing myocardial contractility, dilating blood vessels, regulating coronary blood flow, and also exhibits anti-inflammatory, anti-oxidant and anti-apoptotic effects. Compared with traditional inotropic drugs, levosimendan does not increase calcium ion concentration or increase oxygen consumption. And it does not easily lead to malignant arrhythmia or increase the long-term mortality of patients. Because of its long half-life, intermittent use of levosimendan can improve contractile function for a long time, thereby effectively alleviating the symptoms of patients with advanced heart failure. Patients treated with levosimendan had a higher survival rate, fewer hospitalizations, and a greatly improved quality of life. MicroRNAs (miRNAs) are a class of non-coding RNAs with important regulatory roles. They are 22-nucleotide single-stranded RNAs derived from endogenous hairpin structure transcripts. MiRNAs are reported to be involved in the pathological process of heart remodeling. MiRNAs can be secreted by cells into the peripheral blood and exist stably, which can be used as new diagnostic markers for various diseases. The investigators have previously conducted simultaneous detection of miRNAs in myocardial tissue and peripheral blood in patients with heart failure, and conducted an epidemiological follow-up study. The investigators have identified three cardiac-specific secretory miRNAs (miR-660-3p, miR-665 and miR-1285-3p) which are significantly up-regulated in the plasma of patients with chronic heart failure. Subsequent analysis proved them as valuable biomarkers for the diagnosis and prognosis of heart failure. The investigators hypothesis that the new positive inotropic drug levosimendan improve heart function by regulating the miRNAs in patients with heart failure. This study aims to treat patients with advanced heart failure with levosimendan. By combining the expression of myocardial specific miRNAs, myocardial injury markers, hemodynamics, patient symptoms, long-term prognosis and other clinical indicators, the investigators will explore the relationship between the three myocardial-specific miRNAs expression and cardiac function improvement by levosimendan treatment.
In a prospective cohort study (n = 1.000), the investigators aim to investigate the correlation between cardiac biomarkers and advanced echocardiography and determine whether these are prognostic markers of heart disease in patients suffering from psoriasis.
The renin-angiotensin-aldosterone axis has been found to be a key system involved in heart failure disease progression and it may be inhibited by renal sympathetic denervation. Therefore, a clear need exists for further strategies to beneficially manipulate the sympathetic activation that is characteristic of the heart failure disease process. The combined experience in the pilot studies and the EU randomized, controlled study indicates that the Paradise Catheter System can safely denervate renal sympathetic nerves of the kidney without significant periprocedural complications. Preliminary results of a pilot study of catheter-based renal denervation in a small number of CHF patients did not show evidence of safety issues but suggest improvements in CHF symptoms. This trial will explore the safety and feasibility of renal denervation in a significantly higher number of patients with chronic heart failure. Both inter-individual and intra-individual controls will be used in order to obtain sufficient data and to in order to enable both treatment and control group to receive renal denervation. Additionally, this feasibility trial to describe the safety and feasibility of renal denervation in patients with elevated sympathetic activity as in patients with chronic heart failure, will further the understanding of the role of renal nerves in the control of chronic heart failure and the pathogenesis of both ventricular remodeling and cardio-renal syndrome.
The primary objective of this study is to determine if the correction of functional iron deficiency by administering a single dose of intravenous iron (ferric derimaltose or Monoferric®) in participants with heart failure with preserved ejection fraction (HFpEF) will improve exercise capacity as measured by the change in peak oxygen uptake (peak VO2) from baseline to 12 weeks.
