Filter by:The Enavogliflozin Outcome Trial in Functional Tricuspid Regurgitation (EVENT) was designed to examine the hypothesis that, compared with placebo, therapy with the SGLT2 inhibitor enavogliflozin would improve clinical and echocardiographic outcomes in heart failure (HF) patients with functional tricuspid regurgitation (TR) and preserved left ventricular ejection fraction (LVEF). The primary objective of the EVENT study is to test the hypothesis that, compared with placebo, therapy with enavogliflozin for 18 months would improve a composite of cardiovascular events or worsening of TR on follow-up echocardiography in HF patients with functional TR and preserved LVEF. The secondary objective is to examine whether enavogliflozin is effective in reduction of renal events and tricuspid regurgitation, and to evaluate whether beneficial effects of enavogliflozin on primary outcomes are associated with reduction of all-cause mortality.
Levosimendan, a drug with inotropic, vasodilatory and myocardial protective properties, has been proposed for the prevention and treatment of postoperative low cardiac output syndrome in cardiac surgery. Despite preliminary studies with promising results, large randomized controlled trials aimed at demonstrating the benefits of levosimendan did not show superiority over placebo in this indication. However, in these studies, the infusion was neither performed at the maximum dosage nor during the 24 hours preceding the surgery, but mainly at the very beginning of the operation. However, post hoc analyses showed a reduction in mortality and in the occurrence of low cardiac output syndrome in the subgroup of patients who had undergone isolated coronary artery bypass grafting, in contrast to those who had undergone valvular or combined surgery. Another recent study suggests that under similar conditions, preconditioning with levosimendan started 48 hours before surgery reduces the length of stay in intensive care and the average cost of hospitalization. There are no formal recommendations on the prophylactic use of levosimendan in cardiac surgery for heart failure patients with impaired LVAS. However, the France-Levo registry, a multicenter observational study requested by the HAS, has shown that in real practice there is a place for preconditioning with levosimendan, which is used in this indication for 7% of the patients in the registry. The Cardiovascular Surgery and Transplantation Department of the Nancy Brabois University Hospital, which actively participated in the France-Levo registry, is one of the cardiac surgery centers that uses this practice, as is the University Hospital of Rouen. It is interesting to be able to evaluate retrospectively whether levosimendan preconditioning has a positive impact on the postoperative prognosis of patients and more particularly on the reduction of the length of stay in critical care and in hospital compared to standard management.
The study is designed as an open-label, prospective, international, multicenter, non-randomized study to determine safety and product performance of the CE-marked Amvia/Solvia pacemaker family, including the aATP, CRT AutoAdapt and Early Check features in the setting of a post-market clinical follow-up study.
This study will evaluate the efficacy, safety, tolerability and pharmacokinetics of JTT-861 administered once daily for 12 weeks in subjects with heart failure with reduced ejection fraction (HFrEF) who are on a stable, guideline-directed medical therapy for heart failure.
There is an increased risk of diastolic heart failure in post menopausal women. Estrogen plays a positive role in regulating molecular pathways in heart remodeling. Such pathways may work through purinergic signaling and its downstream effects on the heart's mitochondrial metabolism and angiogenic response to stress. Loss of estrogen functionality in post menopausal women may account for the increased risk of diastolic heart failure. The investigators will explore said pathways using cardiac tissue obtained from patients undergoing cardiac surgery.
Telemonitoring is a key clinical issue in heart failure (HF). Bedside measurement systems using handheld devices provide "digital biomarkers" useful for remote monitoring. A recent systematic review and meta-analysis showed that teleconsultations and telemonitoring at home improved the prognosis of HF patients compared with usual care. Biomarkers contained in exhaled air could constitute "digital biomarkers" in HF, as measurement is non-invasive, and 4 different species have shown their potential interest: NO, CO, acetone and isoprene. The assessment of these species in the exhaled air to remains an issue in the perspective of non-invasive biomarkers in HF. Indeed, it requires selective sensors with low limit of detection. In addition, these sensors should be miniaturizable. Quartz-enhanced photoacoustic spectroscopy (QEPAS) are sensors that are suitable in this context. Last, the measured concentration should be informative and directly related to the HF. However, the concentration each of these biomarkers is not homogeneous during the expiration as it reflects the different lung compartments. While the end-expiratory concentration constitutes a sample of the alveolar concentration (AC) that reflects the blood concentration (BC) of one specie, the relationship between alveolar and blood concentrations is complex as exchanges that take place within these different compartments. Thus, measuring the concentration of a specie in exhaled air during a complete exhalation (or "expirogram") depends not only on the BC of the specie, but also on changes in lung function. Because both BC and changes in lung function depend on the severity of the HF, obtaining a full expirogram each specie should provide valid diagnosis information in HF. The mathematical modelization of real-time QEPAS sensors based expirograms together with lung function parameters (volume, flow) and lung compartment identification (capnography i.e. exhaled CO2 concentration) could provide valid algorithms with a an acceptable diagnosis performance in HF.
The diagnosis of depressed left ventricular ejection fraction (dLVEF) (EF<50%) depends on golden standard ultrasound cardiography (UCG). A wearable synchronized phonocardiography (PCG) and electrocardiogram (ECG) device can assist in the diagnosis of dLVEF, which can both expedite access to life-saving therapies and reduce the need for costly testing.
The purpose of the study is to determine associations between fitness status, bacteria in the mouth, and the blood flow to muscle. This study is trying to find out if fitness status impacts the bacteria that are present in the oral microbiome (environment in the mouth) or the ability of the body to send blood to the skeletal muscle. Participants will complete all or some of the following: - A mouth swab to assess the bacteria in their mouths. - Produce a saliva sample into a tube. - Cycle on a bike until you reach maximum effort. - Undergo blood draws - Wear a 24-hour non-invasive device that monitors blood pressure. - Undergo a test to assess blood flow to the muscles measured with an ultrasound. - Drink 70mL (1/3 of a cup) of concentrated beetroot juice once
Finerenone will be compared to placebo to determine efficacy and safety of treatment in patients hospitalized with acute decompensated heart failure (HF) and mildly reduced or preserved left ventricular ejection fraction.
The primary purpose for this study is to support the hypothesis (pilot data) that the use of the CPM system reduces the rate of HF related events and the related healthcare cost. The study will also measure the impact on quality of care and patient satisfaction. In order to support the primary objective, the study will compare the outcomes and costs for patients using the CPM system against those who are not. This can either be done using institutions averages, if available, or through a control group.
