Aquaresis Utility for Hyponatremic Acute Heart Failure Study

Heart Failure

Hyponatremia is a common finding in acute heart failure (HF) patients and is associated with worse prognosis. In addition to its prognostic value, hyponatremia may have importance during the acute management of HF. We've recently shown that acute or chronic hyponatremia, especially <130 mEq/L, was associated with higher loop diuretic dose requirements and more frequent need for escalation of the diuretic regimen to achieve the same level of diuresis as normonatremic HF patients. Aquaresis with tolvaptan represents a potentially advantageous approach to the management of volume overload in HF, especially in patients presenting with concomitant hyponatremia. The purpose of the current study is to prospectively evaluate the comparative efficacy and safety of a tolvaptan-based diuretic regimen compared to conventional diuresis with a furosemide-based regimen on short-term clinical and treatment outcomes in hyponatremic acute HF patients. This will be a prospective, open-label, parallel-group, randomized study comparing a tolvaptan-based aquaretic regimen to a conventional continuous infusion loop diuretic-based regimen of furosemide. Up to 55 (target sample size of 50) adult subjects admitted with acute HF and signs of volume overload, and serum sodium less than 135 mEq/L will be randomized to tolvaptan or furosemide treatment arms. The initial 24 hours of study treatment will compare tolvaptan monotherapy to furosemide monotherapy. After the initial 24 hours, treatment regimens may be altered to achieve desired clinical goals. Patients will be followed for up to 96 hours and at discharge for study purposes.

Effect of Nitrate-rich Beetroot Juice on Exercise Performance in Heart Failure Patients

Systolic Heart Failure

Nitrate-rich beetroot juice supplementation has demonstrated reduced oxygen consumption and submaximal exercise performance in healthy adults. Investigation for similar effects in patients with heart failure has not previously been conducted. This was a randomized, double-blind, placebo controlled trial. Following ingestion of the active agent or placebo, subjects with systolic heart failure underwent submaximal steady state exercise with gas exchange analysis followed thirty minutes later by a six minute walk test. Second testing sessions were performed ten days. There were no significant differences in the treatment and placebo arms in average oxygen consumption or six minute walk distance. In conclusion, in patients with heart failure who have ingested a single dose of nitrate-rich beetroot juice concentrate, there is no significant difference with regard to oxygen consumption during submaximal steady state exercise or six minute walk testing distance. Further study is warranted to determine the true efficacy of nitrate consumption in this population with adjustments in acute or chronic dosing, exercise duration, or intensity.

Loop Diuretic Dosage in Patients With Acute Heart Failure and Renal Failure: Conventional Versus...

Heart Failure

Worsening renal function (WRF) is a frequent finding in patients with decompensated acute heart failure (AHF) and it is associated to increased length of hospitalization and higher morbidity and mortality. Traditionally, WRF in AHF setting has been attributed to low cardiac output, but recent evidence also suggests venous congestion play a crucial role. Loop diuretics are the mainstay treatment of AHF, but their use traditionally has been associated to WRF, but also renal function improvement in patients with unequivocal signs of congestion. Nevertheless, traditional symptoms or signs of patients with AHF have shown a limited accuracy to neither identify nor quantify the degree of venous congestion. Recent authors have reported that plasma levels of antigen carbohydrate 125 (CA125) are closely related to the degree of venous congestion. The investigators hypothesize that CA125 may have a role for identifying the hyperhydrated (High CA125) patients that need high loop diuretic doses, and those with normal CA125 values needing low loop diuretic doses. In this randomized study (1:1) the investigators seek to evaluate whether a CA125 loop diuretic guided management therapy is superior to a standard strategy. The primary endpoint is the magnitude of changes of renal function at 24 and 72 hours after initiation of intravenous diuretic in an acute worsening of heart failure

12-Week-Combined Physical Training In Heart Failure Patients

Heart Failure Patients

Purpose: Physical exercise exerts favorable impact on functional capacity (FC) and quality of life (QL) in patients with heart failure (HF). It is believed that the combined aerobic and resistance physical training (CPT) supervised by physical educator is better than only prescription of unsupervised exercise. The aim of this study is to compare the effects of a CPT program on the FC and QL of HF patients with reduced ejection fraction (HFREF) with the practice medical routine prescription of regular physical activity and correlate these findings with clinical and echocardiographic variables. Methods: A longitudinal prospective study included 28 consecutive HFREF patients randomly divided in two age- and gender- matched groups: Trained Group (TG, n = 17), patients undergoing 12 weeks of supervised CPT and Non Trained Group (NTG, n = 11), patients receiving only medical prescription to practice regular physical exercise. All patients were submitted to clinical evaluation, transthoracic echocardiography, Cooper walk test and QL questionnaire before and after the study protocol. Student t test or Mann-Whitney test were performed for groups comparison and correlation tests for the same group variable associations.

ENABLE CHF-PC (Comprehensive Heartcare For Patients and Caregivers)

Heart Failure

Advanced heart failure affects nearly 6 million Americans, and less is known about how this illness affects the 80% of heart failure patients who are 65 years and older because research tends to focus on younger patients. Older patients with heart failure and their family caregivers, rarely have access to palliative supportive care services because the disease is unpredictable and palliative treatment may not be provided until after other medical treatments have been tried. Investigators are studying whether palliative care provided when advanced heart failure patients are still well will result in better quality of life, mood and less symptom distress compared to usual or standard heart failure care. Specific Aims and Hypotheses: Specific Aim 1: Determine whether ENABLE CHF-PC leads to higher advanced heart failure patient-reported quality of life (QOL) and mood (depression/anxiety); and lower symptom burden and resource use (e.g. hospital admissions and days, emergency visits) through 16 weeks post baseline. • Hypothesis 1: Intervention participants will experience higher QOL and mood, and lower symptom burden and resource use through 16 weeks post baseline compared with those receiving usual HF care. Specific Aim 2: Determine whether ENABLE CHF-PC leads to higher caregiver-reported QOL, mood (anxiety/depression), and self-reported health and lower caregiver burden through 16 weeks post baseline. • Hypothesis 2: Intervention caregivers will report higher QOL, mood, and self-reported health, and lower caregiver burden through 16 weeks post baseline.

The Role of Peritoneal Dialysis in Patients With Refractory Heart Failure and Chronic Kidney Disease...

Refractory Heart FailureChronic Kidney Disease

In patients with advanced heart failure (HF), systemic congestion is the main indication for hospitalization. Recent evidence has highlighted the role of fluid retention in the pathogenesis of renal dysfunction and subsequent diuretic resistance. Previous kidney disease, diuretic resistance, and progression of renal dysfunction often coexist in patients with HF and persistent volume overload. This clinical presentation represents the most extreme feature of the cardio-renal syndrome. However, available therapeutic options for this ominous condition are scarce and limited. Indeed, there are no data from randomized control trials using pharmacological interventions that support the beneficial effect on survival. Interestingly, intermittent ultrafiltration has recently emerged as an alternative therapeutic option for reducing volume overload in patients with refractory HF. Current literature suggests that it has potential advantages over standard medical treatment particularly in acute stages of HF. Among ultrafiltration methods, peritoneal dialysis (PD) has been preferred as an additional resource for the treatment of advanced congestive heart failure (CHF) compared with hemodialysis because it can provide a more physiological and continuous ultrafiltration. In fact, several studies showed that use of PD improved clinical functional class and hemodynamic parameters and reduced hospitalization rates in patients with CHF. Nevertheless, most studies were limited by retrospective analyses of small sample size, prospective observational design with no control group, or inclusion of patients with end-stage renal failure. Therefore, well-designed prospective randomized controlled studies are mandatory to confirm the effects of PD in these patients.
