Filter by:Following acute cardiovascular injury, inflammation is vital to activate reparative mechanisms. However, there is compelling evidence implicating excessive inflammation and dysregulated resolution in fibrosis, ventricular remodelling, and heart failure (HF). Recently, the anti-inflammatory agent colchicine reduced cardiovascular events after myocardial infarction (MI) compared to placebo, indicating that targeting inflammation in acute cardiovascular conditions is feasible. Several acute cardiovascular conditions are characterised by inflammation, including myocarditis, MI, and acute heart failure. However, there is large variability in definition, epidemiology, clinical presentation, pathophysiology, and natural history of acute inflammatory cardiovascular diseases. This relates, in part, to the difficulty in performing adequately powered studies. Clinical studies that include sufficient patients and extended observation periods are necessary to address some of these knowledge gaps. This registry aims to collate routinely collected clinical data on patients with acute cardiovascular diseases characterised by inflammation in an observational-based registry. By doing so, the investigators hope to understand the contribution of inflammation to the pathophysiology of acute cardiovascular disease, improve risk stratification, and identify potential novel therapeutic targets.
The CLIMATE-II Observational Study examines to what extent chronically ill patients experience adverse health effects because of heat and whether the patients' specific health behavior, somatosensory amplification, risk and benefit perception, self-efficacy, health literacy, degree of urbanisation of the patients' administration district and characteristics of the patients' neighborhood are associated with these effects.
The evidence-based pharmacologic treatments available for patients with heart failure with reduced ejection fraction (HFrEF) has been established over the last few decades of cardiovascular research. These treatments, termed Foundational Guideline-Directed-Medical Therapies (GDMT), prolong patient life, improve patient-reported symptoms, and reduce hospitalizations for heart failure. A direct effect of most medication classes encompassed within GDMT is the reduction in blood pressure due to their mechanisms of action. In addition, as patients with HFrEF become more advanced in their disease, a significant proportion develop hypotension related to pump failure and autonomic dysfunction, amongst other possible mechanisms. As a result, a significant proportion of HFrEF patients are not optimized on GDMT with hypotension as their limiting barrier that would otherwise have served to improve their heart function, heart failure symptoms, and mortality. Currently, there does not exist any evidence-based strategies to address the problem of hypotension in HFrEF patients who are not optimized on GDMT. Midodrine is an alpha-adrenergic agonist (α1-AR) that exerts its effects on peripheral venous and arteriolar vasculature to increase blood pressure. This medication has been used off-label by some clinicians in the hypotensive HFrEF population to increase blood pressure and has been reported to have beneficial effects in improving GDMT utilization as well as increasing left ventricular ejection fraction (LVEF) in published case reports/case series. There does not exist any randomized prospective data on the use of midodrine in the hypotensive HFrEF population. The investigators' objective is to complete the first open-label, randomized control trial of midodrine in the hypotensive HFrEF population to demonstrate feasibility in performing a trial in this patient population and to show efficacy in increasing blood pressure without associated harm. The results of this trial will be used as the foundation and rationale for future studies assessing the impact of midodrine use on GDMT utilization as well as hard cardiovascular outcomes in the hypotensive HFrEF population, including hospitalizations for heart failure and mortality.
The AquaPass is a non-invasive, renal-intended system designed to enhance fluid transfer through the skin, by increasing sweat rate, to treat fluid overload in heart failure patients. This study will further evaluate the safety, efficacy, and usability of the AquaPass system in the hospital and home settings.
The aim of this pilot randomized study is to examine whether integrating the SIRIO-HF virtual assistant (VA) into the outpatient management of participants recently discharged from hospital with a new diagnosis of heart failure (HF), may reduce the need for regular medical assessment and the healthcare burden, reduce variability in healthcare, and meet with participant satisfaction, without compromising participant safety and overall care quality.
The effect of an acute intake of medium-chain fatty acids on heart function measured by cardiac magnetic resonance imaging (CMR) will be measured in individuals with heart failure with reduced ejection fraction (HFrEF) and in matched healthy controls with normal heart function. This aim will be investigated in a cross-over study including two visits: acute intake of medium-chain fatty acid or long-chain fatty acid as control. In addition, the effect of acute medium-chain fatty acid compared with long-chain fatty acid intake on whole-body lipid and glucose metabolism will be investigated.. The hypothesis is that acute consumption of medium-chain fatty acid will improve cardiac function in patients with heart failure.
Acorai is developing the Acorai Heart Monitor, a handheld electronic device for monitoring pressures inside the heart in a non-invasive manner, by placing the device on the chest of a patient. Currently these intracardiac pressures are measured in an invasive way, during a right heart catheterisation procedure. This procedure carries risks to the patient. There is a clinical need for a non -invasive, easy to use, tool to monitor patients that suffer from heart failure. The study aim is to use the Acorai device to collect the intracardiac pressure measurements from patients admitted to hospital with heart failure and who are awaiting discharge home. Using the data, we will assess the feasibility of the Acorai derived cardiac output measurements, and assess what data best predicts survival, death, or major adverse cardiac events (MACE)
This was a multicenter, randomized, double-blind, placebo-parallel-controlled Phase II clinical study to evaluate the efficacy and safety of HRS9531 Injection compared to placebo in obese subjects with heart failure with preserved ejection fraction. A total of 200 obese subjects with heart failure with preserved ejection fraction would be enrolled. Eligible subjects were randomly assigned to either HRS9531 group or placebo group and were treated with HRS9531 injection or placebo, respectively, for 52 weeks.
Heart failure is a syndrome that progresses with symptoms and signs caused by cardiac dysfunction and results in a shortened life expectancy (1). Acute heart failure resulting in hospitalization is a significant cause of morbidity and mortality. With the increase in the severity of the disease and rapid advances in the treatment of heart failure, these patients are frequently hospitalized and monitored in intensive care. (2) Five years after diagnosis, mortality can be up to 67%. Additionally, it is known that patients with heart failure are hospitalized on average once a year after diagnosis. (3) In a multicenter study, it constituted 14% of 3000 cardiac patients admitted to intensive care units. Additionally, due to longer ICU stays, these patients accounted for 33% of total inpatient days. An increasing number of heart failure patients require intensive care due to respiratory failure, regardless of left ventricular ejection fraction. Heart failure accounts for approximately one-third of patient days in intensive care units, and this burden is increasing. This shows that attention should be paid to the quality of care for patients requiring critical care. (2) Multidisciplinary programs have been implemented to deal with the high prevalence. However, the optimal follow-up frequency is unknown. Therefore, some tools are needed to improve patient prognosis (3). Neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker whose values in both urine and plasma have been associated with acute kidney injury (AKI). Although NGAL is an early specific biomarker for AKI, it has not yet come into routine use, but is frequently used in clinical and experimental studies (4). Venous load ultrasonography score (VExUS) is a new systemic congestion scoring method based on inferior vena cava dilation and pulsed wave Doppler (PW-Doppler) morphology of the hepatic, portal and renal veins. It has been proposed as a score to assess systemic congestion.
The objective of this pilot study is to establish evidence to support the validity of HT in improving skeletal muscle function and physical capacity of patients with HFpEF. Our central hypothesis is that HT treatment will lead to improvements in skeletal muscle and microvascular function compared to a control intervention. As a result, we anticipate that patients treated with HT will demonstrate improved skeletal muscle microvascular blood flow and oxygenation resulting in enhanced exercise tolerance. To explore this hypothesis, we propose the following specific aim: Explore the effects of home-based HT on exercise tolerance in patients with HFpEF.
