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.
Primary Aims 1. Evaluate the safety of high-dose spironolactone in combination of patiromer in acute decompensated heart failure patients. 2. Evaluate the efficacy of high-dose spironolactone in combination of patiromer in causing volume loss and symptom relief in patients with ADHF treated with high-dose spironolactone. Secondary Aims 1: Evaluate the effect of high-dose spironolactone on urinary sodium excretion and renal function.
Objective: The Ultrasonic Cardiac Output Monitor (USCOM) is a non-invasive, quantitative method for measuring and monitoring cardiovascular haemodynamic parameters in patients. The aims of this study are: 1. To investigate whether USCOM-derived haemodynamic parameters such as Cardiac output (CO), inotropy and oxygen delivery (DO2) have a role in the diagnosis of patients with a compensated heart failure syndrome (cHFS) or acute decompensated heart failure syndrome (adHFS) 2. To investigate whether USCOM-derived haemodynamic parameters such as CO, inotropy and DO2 correlate with heart failure staging, especially New York Heart Association (NYHA) class and American Heart Association (AHA) stage. 3. To investigate whether USCOM-derived haemodynamic parameters such as velocity time interval (vti), stroke volume (SV), CO, SV index (SVI), CO index (CI), inotropy and DO2 correlate with ejection fraction. 4. To investigate whether USCOM-derived haemodynamic variables may be used as prognostic indicators of 30-day, 6-month and 1-year Major Adverse Cardiac Events (MACE). 5. To evaluate the agreement between hemodynamic measurements obtained using the Ultrasonic Cardiac Output Monitor (USCOM®; USCOM Ltd., Sydney, Australia), and reference standards as determined by 2 Dimensional echocardiography (2D-echo) measurements in groups of haemodynamically stable and unstable adult patients. Design: This prospective observational cohort study will be conducted in the Prince of Wales Hospital in Hong Kong. Setting and Subjects: Patients will be screened and recruited from adult patients either scheduled for elective 2D-echo at a cardiology clinic at the Prince of Wales Hospital, or attending the emergency department at the Prince of Wales Hospital. Interventions: Haemodynamic measurements made using the USCOM and 2D-echo will be compared. In order to assess inter-observer variability, a second, blinded operator will repeated 15% of scans.
Historically, ultrasound imaging of the lung parenchyma has been challenging because of the high total ultrasound energy attenuation and scattering by the air in the lungs. However, recent technological advancements have allowed for rapid assessment of various pulmonary diseases via the use of lung ultrasound. Furthermore, it has been shown that clear reproducible Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal-processing package. The LDS may contain information of significant diagnostic and physiological value regarding the pulmonary parenchyma and vasculature, as well as the cardio-vascular system in general. In a pilot clinical validation study of patients with acute decompensated heart failure (ADHF) patients, LDS signals unique to ADHF patients were identified, that superpose on the normal Lung Doppler Signals (unpublished data). These are high velocity "disorganized" variable signals that are not synchronous with the cardiac cycle but rather sometimes with respiration.
Purpose: To compare the hemodynamic effects of dobutamine and milrinone in hospitalized patients who are receiving Beta Blocker Participants: Patients who are admitted to the General Cardiology and Heart Failure Services at the University of North Carolina Hospitals with acute decompensated heart failure, who have maintained steady state concentrations of beta blocker therapy (carvedilol or metoprolol), and who are deemed by the health care team to require pulmonary artery catheter placement and inotropic therapy with dobutamine or milrinone by continuous infusion. Patients that are not currently receiving beta blocker therapy will be enrolled for comparative purposes; however, any patient not at steady state (on or off beta blocker therapy) will not be enrolled. Procedures: After obtaining informed consent, patients will be assigned to the appropriate sub-study group based on beta blocker use (Study A: patients on stable doses of metoprolol and Study B: patients on stable doses of carvedilol). All patients should receive dobutamine followed by milrinone as outlined in the dosing algorithm (see inotrope dosing algorithm attached, as part of the usual standard of practice). Baseline pulmonary artery catheter hemodynamic parameters will be collected prior to administration of inotrope trial of dobutamine followed by milrinone. Hemodynamic parameters will be recorded per the dosing algorithm following initiation and dose titration. Dose titration will be determined by the health care team based upon patient response or lack thereof and tolerability. Changes in hemodynamic parameters in response to dobutamine or milrinone will be compared within study groups. Additionally, data will continue to be collected on patients receiving not beta blocker therapy for comparative purpose.
To evaluate the overall safety and efficacy of TRV027 when administered in addition to standard of care (SOC) on mortality, morbidity, dyspnea, and length of stay in patients hospitalized with Acute Decompensated Heart Failure (ADHF).
For patients hospitalized with acute decompensated heart failure,volume removal remains the primary therapeutic objective. The current standard of care remains loop diuretics.The high likelihood of readmissions and poor outcomes highlights the need to examine and improve in-hospital protocols for these patients. Ultrafiltration allows for greater volume removal, less neurohormonal stimulation and greater sodium removal.However it is associated with increased costs, line complications, and relative immobility during treatment. Tolvaptan in addition to diuretic therapy has been shown to improve the amount of volume removed compared to diuretic alone. The study proposes to compare the strategy of adding tolvaptan to usual care with ultrafiltration as primary mode of therapy in acute decompensated HF(ADHF) patients. Hypothesis: addition of tolvaptan to usual care for hospitalized HF patients will result in: - greater volume and weight reduction compared with usual care - similar efficacy outcomes compared with ultrafiltration, with less complications of therapy
To compare the therapeutic efficacy of recombinant human brain natriuretic peptide (rhBNP) with dobutamine on acute decompensated heart failure patients with different blood BNP levels
The purpose of this study is to evaluate the efficacy and safety of a continuous intravenous (IV) ularitide infusion on the clinical status and outcome of patients with acute decompensated heart failure (ADHF).
The purpose of this observational study is to collect and characterize multiple physiologic data from a broad subset of subjects with acute heart failure (HF) Changes in physiologic data are expected to correlate with 30-day readmission rates in this population
