Safety and performance evaluation of the preCARDIA System for patients with ADHF.
Holding ACEI/ARBs during initial 72 hours of admission with acute decompensated heart failure may help preserve renal function with a lesser decline in GFR. This treatment modification will also allow the option of aggressive diuresis in volume overloaded CHF patients which should result in a lesser decline of AKI, length of stay, readmission rates, and cost associated with CHF treatment.
A randomized, double-blind, Multicenter, parallel, placebo-controlled study
This clinical research study is being conducted in multiple hospitals in Belgium and approximately 519 patients with acute decompensated heart failure are expected to participate. Large-scale research shows that 90% of the physicians treat volume overload with high doses of loop diuretics. However, there is not a lot of scientific data available regarding the optimal doses of these diuretic medications. In addition, it is observed that a lot of people, treated with these drugs, are being readmitted to the hospital due to a new episode of heart failure. The hypothesis of this study is that the volume overload could be better treated when patients receive a combination of different types of diuretics. Additionally, the total dose of the administrated diuretics might be lower this way.
Heart failure is a common, costly, and disabling condition characterized by recurrent exacerbations. Episodes of acute decompensated heart failure (ADHF) account for the largest proportion of admissions and 30-day readmissions to US hospitals. Medication nonadherence and dietary/fluid nonadherence have been associated with re-admissions. Hand-carried ultrasound (HCU) devices are portable, relatively inexpensive, and can augment the physical exam in the assessment of volume status. Dilated Inferior Vena Cava (IVC) with poor collapsibility correlates with elevated central venous pressure, which may be correlated with earlier readmission for ADHF. Study design to measure maximum IVC diameter (IVC max) in mm and the degree of IVC collapsibility with inspiration on qualitative assessment in approximately 100 patients admitted with ADHF. The co-investigator will share the IVC images and interpretation with educational intervention group patients in real time; IVC images and interpretation will not be shared with control group patients. Study team will assess whether sharing these IVC measurements correlates with greater adherence to heart failure self-management after discharge, as measured by the administration of the Medical Outcomes Study Specific Adherence Scale, modified to a 3-item version relevant for patients with heart failure (MOSSAS-3HF) at 4 weeks after discharge. Study team will also assess for any difference in 30-day readmission rates for intervention vs. control group patients.
The idea behind the Future Patient research project is to develop a telerehabilitation program and tools for patients with heart failure. The hypothesis for this study is that participation in a telerehabilitation program for patients with heart failure will increase the patients' quality of life and multi‐parametric (subjective and objective) individualized monitoring in a telerehabilitation program for patients with heart failure will increase detection of worsening of symptoms and avoid future hospitalization of the HF-patients.
Purpose. The aim of this study is to evaluate whether lung ultrasound, in addition to physical examination, leads to a reduction of the admission rate for acute decompensated heart failure of patients with chronic heart failure (HF) followed in the outpatients heart failure clinic. Methods. This is a prospective randomized study. The planned sample size consists of 440 patients with chronic HF. The inclusion criteria are: (1) male and female aged between 18 and 90 years (2) signed written informed consent (3) history of HF for at least six months, (4) left ventricular ejection fraction < 45%, (5) adequate medical therapy for HF for at least two months. The exclusion criteria are: (1) concomitant enrollment in other clinical studies, or treatment with experimental drugs or devices within 30 days of clinical assessment, (2) inability to undergo to the planned follow-up and procedures (3) documented pulmonary infections (3) interstitial lung disease and class 4 chronic obstructive pulmonary disease according to GOLD classification. Patients are randomized in two groups: group A, patients undergoing to lung ultrasound and physical examination; and group B, patients undergoing to physical examination only. Patients are evaluated at baseline and after three months with medical history, Quality of Life test, physical examination, blood sample for hematochemical (creatinine, electrolytes, BNP/NTpro-BNP). The diuretic therapy is then optimized according to the presence and severity of B-lines in group A and physical examination in group B. Only patients enrolled in group A undergo to a lung ultrasound examination to assess the extent of pulmonary congestion, through its evidence of B-lines. B-lines originate from the contrast between air-filled structures and water-thickened pulmonary interlobular septa. This leads to linear echogenic vertical artefacts that spread from the pleural layers downwards in the screen. The ultrasound examination is performed with a handheld echocardiography device. The physician carries out a scan of the pulmonary fields, from basal towards mid and apical fields, through the midaxillary line while the patient lies supine. The quantification of B-lines is performed according to their extent over the lung fields. All the information are recorded in dedicated forms. The results are evaluated according to the following criteria. The primary end-point is a significant reduction of hospitalizations for acute decompensated HF in group A during the follow-up period. The secondary end-points are changes of NT-proBNP values, quality of life test (QLT) score and cardiac mortality.
A randomized study designed to determine whether telephone based interventions can prevent return hospital visits for elderly and frail patients with acute symptoms of heart failure. Specifically, the intervention will improve patients ability to monitor and address self care of heart failure at home.
This is an exploratory study to evaluate lung ultrasound as a method for measuring extravascular lung water in stabilized patients during hospitalization for ADHF. Subjects who have been stabilized following admission for ADHF and capable of lying supine will be evaluated by lung ultrasound to determine the degree of lung congestion as measured by the total B-line score. Since different patients may require different degrees of postural change and/or other maneuvers (e.g., leg elevation or exercise) to induce B-line increments, a tailored sequential protocol will be employed to define which maneuvers are sufficient for each patient.
Acute Decompensated Heart Failure (ADHF) is a major cause of morbidity and mortality. It is associated with increased systemic inflammation. Previous studies have demonstrated increased levels of cytokines such as C-reactive protein (CRP), interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-10 (IL-10) and Tumor Necrosis Factor alpha (TNFα) in patients with heart failure (HF). Increased activity of sympathetic nervous system in ADHF is linked to inflammation. Previous anti-inflammatory drug therapies in HF have demonstrated no significant impact on cardiovascular outcomes. Low-level vagus nerve stimulation (LLVNS) is a non-invasive way to modulate autonomic tone and thereby inflammation. Vagal nerve stimulation is thought to increase the parasympathetic activity and suppress the sympathetic activity. Clinical studies of vagal stimulation in chronic HF have been negative. Recent experimental and clinical data suggest that low level tragus nerve stimulation (LLTNS) may produce the same desired neuromodulator effect compared to LLVNS. It is however unknown if LLTNS in ADHF will directly lead to a reduction in the levels of pro-inflammatory cytokines (CRP, IL-1, IL-6 and TNF-α) and an increase in the level of anti-inflammatory marker IL-10.The objective of this proposal is to determine the impact of LLTS on inflammatory cytokines in patients with ADHF. Patients will be randomized to either active or no stimulation(~8 hours daily). Serum collected will (post admission and on days 2, 3 and 4 post admission) will be used for cytokine measurement. This investigation will likely establish the first evidence of effects of LLTS on suppression of inflammation in patients presenting with ADHF.
