Filter by:The aim of PLUTO-II is to use biventricular pressure-volume (PV) loop measurements to improve the understanding of direct changes in cardiac and hemodynamic physiology induced by transcatheter aortic valve implantation (TAVI) or tricuspid edge-to-edge repair (TEER). These procedures evoke immediate changes in cardiac mechanoenergetics, ventricular-vascular interaction as well as ventricular (in)dependency. Within the context of PLUTO-II, patients will undergo biventricular PV-loop measurements before and after TAVI or TEER. In future, the application of perprocedural PV loop monitoring may tailor the daily individual decision making process during structural interventions in the catheterization laboratory.
Cardiac amyloidosis (CA) has recently been reported as a common cause of heart failure with preserved left ventricular ejection fraction (HFpEF), with a prevalence of 6% in elderly HFpEF patients. However, the diagnosis of CA is still challenging and requires multiple costly investigations. Regardless of the type of CA, TTR or AL, early diagnosis significantly improves prognosis. In this study, the investigators aimed to determine the prevalence of CA in Tunisian HFpEF patients and to identify clinical and ultrasound criteria predictive of CA.
Sodium-glucose cotransporter 2 (SGLT2) inhibitors have shown further reductions in heart failure hospitalization, cardiovascular events, and mortality, especially for heart failure patients. The SGLT2 gene, also known as SLC5A2 (solute carrier family 5 member 2), is located on chromosome 16 and is responsible for encoding SGLT2. Several SLC5A2 mutations alter SGLT2 expression, membrane location, or transporter function. Several common genetic variations were found in the SLC5A2 gene that may affect the response to treatment with SGLT2 inhibitors.
The study is being done to see if ziltivekimab can be used to treat participants living with heart failure and inflammation. Participants will either get ziltivekimab (active medicine) or placebo (inactive substance that looks like the study medicine but does not contain any medicine). The treatment participants get is decided by chance. Participant's chance of getting ziltivekimab or placebo is the same. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe. The study is expected to last for up to 1 year and 4 months.
Patients with severe aortic stenosis combined with severe heart failure often miss the opportunity for surgery, and the prognosis is poor with drug therapy alone.In recent years, the emergence of transcatheter aortic valve replacement (TAVR) has brought new hope for these patients, and since its birth in 2002, TAVR has been widely used internationally, and its safety and efficacy have been confirmed by several large, prospective, randomized controlled studies. Levosimendan is a new type of positive inotropic drug. It not only enhances myocardial contractile force through calcium sensitization, but also activates K+ sensitive channel KATP on the membrane of vascular smooth muscle, relaxes the arteries and veins of the whole body, and reduces the front and back load of the heart, pulmonary vascular resistance and systemic vascular resistance. A series of studies suggested that for patients undergoing thoracotomy in various cardiac surgeries, regardless of whether the patients were accompanied by ventricular systolic dysfunction before surgery, the use of levosimendan resulted in significantly higher postoperative cardiac function and decreased mortality than the control group, and patients with preoperative LVEF < 40% benefited more. At present, there are no studies to clarify the regulatory effect of levosimendan on cardiac function after TAVR in patients with severe aortic stenosis complicated with cardiac insufficiency. This is a randomized controlled study. On the basis of basic drug therapy, the treatment group was given levosimendan to analyze the regulatory effect of levosimendan on cardiac function after TAVR.
The goal of this observational study is to evaluating myocardial stiffness in patients with heart failure with preserved ejection fraction (HFpEF) by intrinsic wave velocity propagation (IVP). The main questions it aims to answer are: - Whether myocardial stiffness assessed by IVP in patients with HFpEF Increased. - Whether IVP is related to the cardiac structure and function in patients with HFpEF. - What are the risk factors that may be associated with heart failure rehospitalization in patients with HFpEF? - Whether increased myocardial stiffness is a risk factor for heart failure rehospitalization. Participants will undergo transthoracic echocardiography to obtain conventional ultrasound parameters, and software post-processing analysis to obtained two-dimensional strain parameters and IVP, as well as general clinical data and laboratory test results. Clinical followed up was performed through electronic medical records or telephone interviews until patient rehospitalization for heart failure or discharge for one year.
Researchers are looking for a better way to treat people who have chronic heart failure with reduced ejection fraction. Chronic heart failure with reduced ejection fraction (HFrEF) is a long-term condition that occurs when the heart is too weak to pump enough blood to the rest of the body. This results in a reduced supply of the oxygen that the body requires to function properly. The common symptoms of HFrEF include breathlessness, weakness, fatigue, and swelling in the ankles and legs. If left untreated, heart failure can lead to other serious health problems, including damage to other organs, which may result in hospital stays or even death. Vericiguat is an approved drug for use in people with chronic HFrEF. It works by activating a protein called soluble guanylate cyclase, which helps dilating the blood vessels and in turn improves heart function. Currently, treatment with vericiguat starts at a daily dose of 2.5 milligrams (mg), which increases to 5 mg after 2 weeks. The dose is then increased to the target dose of 10 mg after another 2 weeks. In this study, researchers are trying to learn how well participants can tolerate and how safe it is to start vericiguat at a dose of 5 mg. Starting directly at the 5 mg dose is expected to help reach the target dose of 10 mg faster. Participants will take vericiguat 5 mg as a tablet by mouth once daily along with their regular heart medications. At the start of the study, study doctors will check participants' medical history and perform full health check-ups to confirm if they can take part in the study. Throughout the study, study doctors will monitor participants' previous and current medications, their heart health, and their overall well-being. This will help researchers assess how safe the study drug is and if they experience adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective of whether they think they are related to the study treatment. Access to study treatment after the end of this study is not planned. Everyone, including study doctors and participants, will know what drug the participants receive during the study. Participants may be in the study for about 4 weeks. Participants may not benefit from the treatment as the study is designed to assess safety and tolerability: the duration of the study is very short and participants will be taking a low dose of vericiguat without moving to the target dose of 10 mg during the study. However, the findings of this study may enable people with chronic HFrEF to safely skip one initial dosing step and reach the target dose of vericiguat faster. Participants may experience medical problems such as low blood pressure, upset stomach, nausea, dizziness, and headache. Researchers will monitor and manage all these, and other, medical problems participants may have during the study.
The purpose of this study is to evaluate whether pulmonary blood volume (PBV) derived from contrast echocardiography can serve as a non-invasive surrogate for invasive pulmonary artery wedge pressure (PAWP) during exercise. Also, to compare changes in PBV with exercise in patients with and without heart failure and pulmonary vascular disease.
This study will involve LVAD patients who have already received a clinically-indicated BAT (BAROSTIM) device. After recovery from LVAD implant, we will investigate the effects of BAT in a double-blind cross-over study design.
