Insights

Chronic heart failure with preserved ejection fraction (CHFpEF) subphenotypes show distinct clinical and laboratory traits. Higher neuropilin-1 (NRP-1) levels correlate with reduced left ventricular ejection fraction (LVEF) in CHFpEF patients.

Area of Science:

  • Cardiology
  • Heart Failure Research
  • Biomarker Discovery

Background:

  • Chronic heart failure with preserved ejection fraction (CHFpEF) presents significant clinical heterogeneity.
  • Understanding CHFpEF mechanisms and patient stratification requires subphenotype identification.
  • Ischemic heart disease is a common comorbidity in CHFpEF.

Purpose of the Study:

  • To identify clinical, laboratory, and instrumental characteristics of CHFpEF patients with ischemic heart disease.
  • To explore differences in CHFpEF subphenotypes based on left ventricular ejection fraction (LVEF).
  • To investigate the association of specific biomarkers with LVEF in CHFpEF.

Main Methods:

  • Study included 145 patients with CHFpEF undergoing coronary artery bypass grafting.
  • Patients were stratified into two groups: LVEF 50-60% and LVEF >60%.
  • Assessed echocardiography, laboratory tests, and plasma biomarkers including NT-proBNP, VEGF, H-FABP, ST2, VCAM, PAI-1, and NRP-1.

Main Results:

  • CHFpEF subphenotypes exhibit varied clinical and laboratory profiles.
  • Higher concentrations of neuropilin-1 (NRP-1) were significantly associated with lower LVEF in the CHFpEF cohort.
  • Specific biomarkers demonstrated differential expression across LVEF subgroups.

Conclusions:

  • Subclassification of CHFpEF patients based on LVEF reveals distinct characteristics.
  • Neuropilin-1 emerges as a potential biomarker associated with reduced LVEF in CHFpEF.
  • Further research into CHFpEF subphenotypes may improve patient management and therapeutic strategies.

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...

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

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...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Heart Failure I: Introduction01:27

Heart Failure I: Introduction

Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Heart Failure VII: Nursing Interventions

The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...
