Filter by:Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). Dapagliflozin was recently granted approval for heart failure by the European Commission, regardless of ejection fraction and whether the patient has diabetes. Real-world observational data are necessary to describe dapagliflozin use in real-world settings in order to assess treatment patterns, HF symptoms and their impact on physical limitation, HRQoL and work productivity, as well as health care utilization of patients treated with dapagliflozin in this setting under local treatment standard conditions in Germany.
The objective of our research is to evaluate the effectiveness of an innovative medical device designed to measure foot and lower leg sizes in detecting early indications of deteriorating heart failure. This health condition frequently causes leg swelling and breathing difficulties due to fluid accumulation. Early detection of these symptoms is vital for effective management, potentially preventing the need for hospitalization. Fluid retention in the lower legs and lungs, manifesting as swollen ankles and shortness of breath, is a common sign of progressing heart failure. Often, a slight increase in body weight is the first warning of fluid accumulation, occurring before noticeable swelling or breathing issues arise. Early identification of these fluid accumulation signs is critical for timely intervention, which can avert the necessity for hospital admittance. Patients are usually encouraged to monitor their weight, check for swelling in the ankles, observe their breathing, and consult with their healthcare provider or heart failure specialist at the first sign of these symptoms. In many cases, patients can report these symptoms in time for their healthcare team to adjust their treatment accordingly. Diuretics, or water pills, are often prescribed to help eliminate excess fluid, effectively preventing hospital admissions when used promptly. The Heartfelt device may provide a useful solution for individuals who find it challenging to consistently monitor these indicators and their weight. It is designed to detect early warning signs seamlessly without imposing additional tasks on the patient's daily routine. The device, intended to complement rather than replace self-monitoring practices, is user-friendly and operates by scanning the feet for any size changes, positioned conveniently by the bedroom floor. This capability allows healthcare professionals to make informed decisions swiftly about patient care, potentially adjusting treatments to avoid further health complications. The device captures images of the feet only, ensuring privacy. This study aims to ascertain the device's practical effectiveness in real-world scenarios, aiming to collect precise data to confirm its potential benefits for patients facing heart failure challenges.
A clinical trial of exercise-similar heart rate acceleration delivered via cardiac pacing vs. sham intervention in subjects at rest will be performed. The study population comprises subjects with guideline-directed medically managed severe left ventricular dysfunction due to ischemic or non-ischemic cardiomyopathy and an existing implantable cardioverter defibrillator or biventricular implantable cardioverter defibrillator. The purpose of the study is to understand how the heart rate pattern of exercise contributes to the considerable cardiac conditioning effects of exercise and estimate whether the pacing approach may have translational clinical applicability. Fifty-two subjects will be randomized, single-blinded, to either the pacing intervention or a sham intervention which they will receive once daily, 3 days/week for 6 weeks. Baseline symptoms and clinical test results will be compared to the same measures at 2 weeks, 4 weeks and 6 weeks of intervention/sham and at 3 months and one-year post-intervention. The primary endpoint will be the change in left ventricular ejection fraction from baseline in intervention vs. sham groups (mixed effects linear regression with time and treatment arm as fixed effects and pre-specified covariates of sex and cardiomyopathy type as random effects). Secondary endpoints will include changes in quality of life, 6-minute walk distance, cardiopulmonary exercise test (CPET) measures, daily activity and major adverse cardiac events (MACE) at 3 and 12 months between pacing and sham groups. A "dose-response" analysis of outcomes at 2, 4, and 6 weeks of the intervention vs. sham compared with baseline will be performed.
Heart failure (HF) patients often develop pulmonary hypertension (PH) that leads to transition into a biventricular HF with poor prognosis. There are two PH components: 1) passive transmission of increased left atrial pressure, 2) heart failure (HF) related pulmonary vascular dysfunction (PVD) with increased vascular resistance. Intriguingly, only some, but not all HF patients develop heart failure-related PVD. The mechanisms and non-invasive detection of HF-PVD are poorly understood and are the focus of the current grant application. Development of PVD is linked to insufficiently characterized metabolic factors that may be mediators of HF-PVD. Untargeted metabolomics is an emerging powerful platform for the discovery of pathways linked to diseases. Its specificity can be further enhanced using transpulmonary gradient sampling. Part A of the project aims to identify novel metabolites associated with the presence of PVD in patients with HF that can serve as biomarkers or targets and will provide biologic insights into PVD. Part C will assess the effects of reverting of metabolic alterations (identified in part A) by a drug/diet on pulmonary vasculature in experimental HF-related PVD. The "gold standard" for the detection of PVD is right heart catheterization, which is invasive and risky. Heart failure-related PVD is therefore often diagnosed late. There is a need for noninvasive tests that may help to detect PVD in early stages and can be done repeatedly. Recent advances in artificial intelligence (AI)-assisted automated quantitative analysis of lung texture from low-dose contrast-free high-resolution CT images allow to quantify lung water content, interstitial changes or vessel volume, and may provide clues for detection of heart failure-related PVD. Such an approach, not tested yet, will be utilized for the detection of HF-PVD (part B). Clinical and functional characteristics of lung circulation (exercise hemodynamics, diffusion capacity, perfusion) will be analyzed in relation to quantitative CT data.
Prolonged pulmonary venous congestion culminates in pulmonary hypertension, defined as a mean pulmonary arterial pressure > 20 mmHg and pulmonary artery wedge pressure >15 mmHg at rest, as determined by right heart catheterization. Pulmonary hypertension secondary to heart failure (PH-HF) is further stratified into isolated post-capillary pulmonary hypertension (Ipc-PH, pulmonary vascular resistance (PVR) is ≤2 Woods Unit) and combined pre- and post-capillary pulmonary hypertension (Cpc-PH, PVR > 2 Woods Unit), the later reflecting additional pulmonary vascular constriction or remodeling in addition to passive PH. While medications tailored for World Health Organization defined Group I pulmonary arterial hypertension are not endorsed for PH-HF according to current guidelines, the coexistence of pulmonary hypertension exacerbates the severity of heart failure. Given the presence of pulmonary arterial vasoconstrictor and heightened sympathetic nervous activity in patients with heart failure, the PADN-5 study has demonstrated the safety and efficacy of pulmonary artery denervation (PADN) for patients with CpcPH, characterized by the improvements in left ventricular ejection fraction, cardiac output, clinical outcome, and reductions in left atrial pressure, pulmonary arterial pressure, and PVR. Our objective is to assess the feasibility, safety, and efficacy of PADN for patients with heart failure independent of left ventricular ejection fraction (HFrEF or HFpEF) without pulmonary hypertension (N=30, 15 with HFrEF and another 15 with HFpEF).
The objective of this randomized clinical trial is to compare the effects of a standardized exercise program alone versus the same program combined with neuromuscular electrical stimulation in patients undergoing heart failure . The main questions it aims to answer are: - Assessing the ultrasonographic parameters: echo intensity (echogenicity), cross-sectional area, thickness, and pennation angle of the rectus femoris muscle in both lower limbs. - Evaluating the strength of the femoral quadriceps muscle - Evaluating the changes in the chronaxie of the rectus femoris muscle in both lower limbs The protocol will have a total duration of 35 days, with an initial intervention period of 21 days (5 days per week), followed by a 14-day follow-up period.
CO-CREATION-HF aims to evaluate the effectiveness of a comprehensive and hybrid cardiac rehabilitation model compared to supervised exercise alone.
According to the World Health Organization (WHO), by 2021 cardiovascular diseases (CVD) will be a public health problem, among them heart failure (HF), since this is a chronic disease, patients should be competent in their care. Despite the above, according to research conducted in Colombia, 59.7% of people with chronic noncommunicable diseases (NCDs) have a level of care competence considered not optimal; patients report not having sufficient knowledge of the disease or experience feelings of lack of tools for the management of symptoms and the challenges of post-hospitalization. The objective of the research is to determine the effect of the PLAN CUIDARTE on the caregiving competence of people with HF Methodology: Pre-posttest randomized clinical trial, with blinding of the participants, where the intervention "PLAN CUIDARTE" is applied and the initial and subsequent caregiving competence is evaluated in the comparison group and in the intervention group for pretest - posttest and between-group comparisons.
Patients with heart failure and a preserved left ventricular ejection fraction (HFpEF) almost invariably complain of exertional breathlessness. Abnormal cardiac hemodynamics with pulmonary congestion are believed to trigger dyspnea in this patients. However, some patients may complain of exertional breathlessness which seems to be out of proportion as compared with hemodynamic abnormalities. Chemoreflex sensitivity accounts for the ventilatory responses to a variety of chemical stimuli, including carbon dioxide produced by the organism during exercise. Chemoreflex sensitivity can be augmented in heart failure with reduced left ventricular ejection fraction, and an increased chemoreflex sensitivity has been linked to symptoms, neurohumoral activation, breathing disturbances, and adverse prognosis. However, the clinical correlates and implications of chemoreflex sensitivity in HFpEF have not been accurately studied. We aim to characterize chemoreflex sensitivity in patients with a diagnosis of HFpEF, and to correlate chemoreflex sensitivity with clinical and hemodynamic characteristics.
This is a Phase III, international, multi-centre, randomised, double-blind, parallel-group, double-dummy, active-controlled, event-driven study in patients with chronic HF and impaired kidney function who had a recent HF event. The aim is to evaluate the effect of balcinrenone/dapagliflozin vs dapagliflozin, given once daily on top of other classes of SoC, on CV death and HF events.
