Insights

Urinary ketone bodies are linked to heart failure severity. Higher ketone levels correlate with worse echocardiographic measurements, indicating potential biomarkers for heart failure progression.

Area of Science:

  • Cardiology
  • Metabolomics
  • Biomarker Discovery

Background:

  • Heart failure (HF) diagnosis and severity assessment rely on clinical and echocardiographic parameters.
  • Identifying novel biomarkers for HF severity is crucial for improved patient management.

Purpose of the Study:

  • To investigate the association between urinary metabolites and echocardiographic measurements in patients with systolic heart failure.
  • To determine if urinary metabolite profiles correlate with the severity of heart failure.

Main Methods:

  • A cohort of 46 patients with systolic HF and 32 controls underwent echocardiography.
  • Urinary metabolites were quantified, excluding patients with type 2 diabetes mellitus.
  • Statistical analyses, including multiple linear regression, were performed to identify associations.

Main Results:

  • HF patients exhibited significantly different urinary levels of acetate, acetone, cytosine, methylmalonate, phenylacetylglycine, and 1-methylnicotinamide compared to controls.
  • Urinary ketone levels, including acetoacetate and acetone, varied significantly with New York Heart Association (NYHA) classification.
  • Urinary ketones independently predicted left ventricular ejection fraction and E/E' ratio.

Conclusions:

  • Urinary ketone bodies are significantly associated with echocardiographic parameters indicative of heart failure severity.
  • These findings suggest that urinary ketones may serve as potential biomarkers for assessing HF magnitude and progression.

Diabetic Ketoacidosis l: Introduction

DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic ketone production, and...

Diabetic Ketoacidosis ll: Pathophysiology

Diabetic ketoacidosis (DKA) is a metabolic emergency characterized by hyperglycemia, ketonemia, and metabolic acidosis. It results from severe insulin deficiency and an excess of counterregulatory hormones, leading to uncontrolled lipolysis, ketogenesis, and widespread electrolyte and fluid disturbances.Pathophysiology The central event in DKA is a profound loss of insulin action. Without insulin, glucose uptake in insulin-dependent tissues is impaired, while hepatic glucose production...
Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...
