Diuretics in chf

Heart failure (HF) with preserved ejection fraction (HFpEF) refers to a clinical condition in which the signs of HF, such as pulmonary congestion, peripheral edema and increased natriuretic-peptide levels, are present despite normal ejection-fractions and the absence of other causes (e.g. pericardial disease). The ejection-fraction cutoff for the definition of HFpEF has varied in the past, but recent society guidelines have settled on a consensus of 50%. HFpEF is particularly common in the elderly. The aim of this narrative review is to summarize the available literature regarding HFpEF in the elderly in terms of evidence for the age-dependence, specific clinical features and underlying mechanisms...

PURPOSE OF REVIEW: Diuretics are the cornerstone therapy for acute heart failure (HF) and congestion. Patients chronically exposed to loop diuretics may develop diuretic resistance as a consequence of nephron remodelling, and the combination of diuretics will be necessary to improve diuretic response and achieve decongestion. This review integrates data from recent research and offers a practical approach to current pharmacologic therapies to manage congestion in HF with a focus on combinational therapy...

INTRODUCTION: Acute heart failure (AHF) is a critical, costly condition with high mortality rates, affecting millions annually. Despite advances in cardiovascular care, AHF treatment lacks robust evidence. AHF commonly manifests with sudden heart failure symptoms such as pulmonary congestion, and the pathophysiology involves fluid overload. Initial treatment is based on intravenous diuretics typically, but the optimal combination of drugs remains uncertain. METHODS AND ANALYSIS: We will systematically review randomised controlled trials enrolling patients with AHF and volume overload undergoing in-hospital diuretic treatment...

In patients with fluid overload and congestion, parenteral diuretic therapy is frequently utilized. However, administration of parenteral diuretic therapy commonly requires hospital admission or outpatient clinic visits. Furoscix (scPharmaceuticals, Burlington, MA), a subcutaneous formulation of furosemide designed for home use, offers new treatment possibilities with the potential for profound cost savings for patients and health systems. Currently, subcutaneous furosemide formulations have been studied in palliative care populations and outpatient clinics, however, new literature has evaluated utility in prescribing on discharge from the emergency department...

There are two significant groups of infection regarding ascitic fluid: spontaneous bacterial peritonitis (SBP) and culture-negative neutrocytic ascites (CNNA). SBP and CNNA typically occur in patients with cirrhosis. A 46-year-old male with end-stage biventricular heart failure presented with a heart failure exacerbation. He was treated with intravenous diuretics with the improvement of hypervolemia. He remained hospitalized to undergo an evaluation for tricuspid valve repair, but given the severity of his bi-ventricular heart failure, he underwent a heart transplant evaluation...

BACKGROUND: Empagliflozin reduces the risk of heart failure events in patients with type 2 diabetes at high cardiovascular risk, chronic kidney disease, and in those with prevalent heart failure irrespective of ejection fraction. While EMPACT-MI showed empagliflozin does not reduce the risk of the composite of hospitalization of heart failure and all-cause mortality, the impact of empagliflozin on first and recurrent heart failure events in patients after myocardial infarction is unknown...

BACKGROUND: Increased renal sodium avidity is a hallmark feature of the heart failure syndrome. SUMMARY: Increased renal sodium avidity refers to the inability of the kidneys to elicit potent natriuresis in response to sodium loading. This eventually causes congestion, which is a major contributor to hospital admissions and mortality in heart failure. KEY MESSAGES: Important novel concepts such as the renal tamponade hypothesis, accelerated nephron loss, and the role of hypochloremia, the sympathetic nervous system, inflammation, the lymphatic system, and interstitial sodium buffers are involved in the pathophysiology of renal sodium avidity...

Heart failure (HF) remains a major cause of morbidity and mortality worldwide. Recently, significant advances have been made in its treatment; however, diuretics remain the cornerstone in managing congestion in HF. Although diuretic resistance poses a significant challenge in the management of HF and is associated with poor outcomes, only limited alternative pharmaceutical options are available in clinical practice. The objective of this narrative review is to provide a comprehensive analysis of the current evidence on the effects of sodium-glucose co-transporter-2 (SGLT-2) inhibitors on diuretic resistance in HF patients...

Congestion is the main therapeutic target of acute heart failure (HF) treatment, and loop diuretics (LDs) are widely used drugs for this purpose. Despite their extensive use, these agents remain largely understudied in terms of modality administration, treatment duration, and escalation dose for subjects responding poorly to therapy. LDs were initially investigated in several edematous statuses such as cirrhosis, nephrotic syndrome, and congestive HF and initially approved for the treatment of cardiogenic congestion in 1966...

Because signs of congestion are associated with adverse outcomes in patients with acute heart failure (AHF), attempts were made to decongest patients as much as possible with diuretic agents (loop diuretic agents, thiazides, acetazolamide) or mechanical devices. Those interventions improved signs of congestion but failed to meaningfully improve patients' symptoms, improve quality of life, or reduce early readmissions or deaths. Recent studies have shown that implementation of guideline-directed medical therapies after an AHF admission led to both more decongestion and improved symptoms, quality of life, and outcomes...

Heart failure with preserved ejection fraction (HFpEF) is a multi-organ systemic syndrome that involves cardiac and extra-cardiac pathophysiological abnormalities. Its growing prevalence causes a major public concern worldwide. HFpEF is usually associated with multiple comorbidities, and non-cardiovascular death is common in patients with HFpEF. In Asia, patients with HFpEF has a younger age, higher prevalence of diabetes and chronic kidney disease than Western countries. A 2-step diagnostic algorithm is recommended in this guideline...

BACKGROUND: Newborns with critical congenital heart disease (CCHD) with increased pulmonary blood flow (PBF) are at high risk for congestive heart failure. In this study, we aimed to evaluate the presence and degree of pulmonary edema in newborns with CCHD using lung ultrasound (LUS) during the perioperative period. METHODS: Prospective clinical trial, 44 newborn patients with CCHD were evaluated in this prospective clinical trial. LUS was repeatedly performed to determine the course of pulmonary edema during the perioperative period...

BACKGROUND: In Mexico, the epidemiology of heart failure is still not well understood. However, it is known that the primary cause of hospital admissions in patients with heart failure is pulmonary and systemic congestion. OBJECTIVE: To estimate congestion status and assess cardiac function using portable ultrasound in patients with heart failure. METHOD: A cross-sectional observational study was conducted. Patients who attended the Heart Failure Clinic at the Ignacio Chávez National Cardiology Institute in Mexico City between May and August 2022 were selected...

AIMS: The current literature provides limited guidance on the best diuretic strategy post-hospitalization for acute heart failure (AHF). It is postulated that the efficacy and safety of the outpatient diuretic regimen may be significantly influenced by the degree of fluid overload (FO) encountered during hospitalization. We hypothesize that in patients with more pronounced FO, reducing their regular oral diuretic dosage might be associated with an elevated risk of unfavourable clinical outcomes...

AIM: Vascular congestion may lead to an increase of carbohydrate antigen 125 (CA-125). The role of CA-125 as a biomarker of congestion or for prognosis across the full ejection fraction (EF) spectrum of chronic heart failure (HF) remains unknown. METHODS AND RESULTS: Serum CA-125 was measured in 1111 study participants from the EMPEROR-Reduced and EMPEROR-Preserved trials. Congestive signs and symptoms were evaluated across CA-125 tertiles. Cox regression was used to study the association with outcomes...

The patient was a male infant, born full-term, admitted to the hospital at 28 days of age due to jaundice for 20 days and abdominal distension for 15 days. The patient developed symptoms of jaundice, hepatosplenomegaly, massive ascites, and progressively worsening liver function leading to liver failure, severe coagulation disorders, and thrombocytopenia one week after birth. Various treatments were administered, including anti-infection therapy, fluid restriction, use of diuretics, use of hepatoprotective and choleretic agents, intermittent paracentesis, blood exchange, and intravenous immunoglobulin, albumin, and plasma transfusions...

Heart failure is increasingly prevalent and is estimated to increase its burden in the following years. A well-reported comorbidity of heart failure is renal dysfunction, where predominantly changes in the patient's volume status, tubular necrosis or other mechanical and neurohormonal mechanisms seem to drive this impairment. Currently, there are established biomarkers evaluating the patient's clinical status solely regarding the cardiovascular or renal system. However, as the coexistence of heart and renal failure is common and related to increased mortality and hospitalization for heart failure, it is of major importance to establish novel diagnostic techniques, which could identify patients with or at risk for cardiorenal syndrome and assist in selecting the appropriate management for these patients...

AIMS: Growth differentiation factor-15 (GDF15), a cytokine in the transforming growth factor family, is up-regulated in stress and inflammatory conditions and is elevated in patients with heart failure (HF). However, the age-specific attributes and prognostic significance of GDF15 across age remain unknown in chronic HF (CHF). METHODS AND RESULTS: Serum levels of GDF15 were examined in 942 hypertensive patients (median 68 years) with CHF from the SUPPORT trial across the four age groups [under 50 (n = 73), 51-59 (n = 158), 60-69 (n = 296), and 70-79 years (n = 415)] and in the continuous spectrum...

Volume overload represents a hallmark clinical feature linked to the development and progression of heart failure (HF). Alleviating signs and symptoms of volume overload represents a foundational HF treatment target that is achieved using loop diuretics in the acute and chronic setting. Recent work has provided evidence to support guideline-directed medical therapies, such as sodium glucose cotransporter 2 (SGLT2) inhibitors and mineralocorticoid receptor (MR) antagonists, as important adjunct diuretics that may act synergistically when used with background loop diuretics in people with chronic HF...

BACKGROUND: Recent evidence suggests that acetazolamide may be beneficial as an adjunctive diuretic therapy in patients with acute decompensated heart failure (HF). We aim to pool all the studies conducted until now and provide updated evidence regarding the role of acetazolamide as adjunctive diuretic in patients with acute decompensated HF. METHODS: PubMed/Medline, Cochrane Library, and Scopus were searched from inception until July 2023, for randomized and nonrandomized studies evaluating acetazolamide as add-on diuretic in patients with acute decompensated HF...
